PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus. It does not contain all of the information that you should consider before investing in our common stock. You should read the entire prospectus carefully, including the section entitled “Risk Factors” and our consolidated financial statements and the related notes.

Unless the context otherwise requires, all references to “we,” “us,” “our,” or the “Company” in this prospectus refer to Network-1 Security Solutions, Inc., a Delaware corporation.

The Company

Our principal business is the acquisition, development, licensing and protection of our intellectual property. We presently own six patents issued by the U.S. Patent Office that relate to various telecommunications and data networking technologies (the “Patent Portfolio”) and include, among other things, patents covering the delivery of power over local area networks (“LANs”) for the purpose of remotely powering certain devices, such as wireless access ports, IP phones and network based cameras, over Ethernet (“PoE”) networks and systems and methods for the transmission of audio, video and data (LANS) in order to achieve higher quality of service (QoS). Our strategy is to pursue licensing and strategic business alliances with companies in industries that manufacture and sell products that make use of the technologies underlying our Patent Portfolio as well as with other users of the technologies who benefit directly from the technologies, including corporate, educational and governmental entities.

To date, our efforts with respect to our Patent Portfolio have focused on licensing our patent (U.S. Patent No. 6,218,930) covering the control of power delivery over Ethernet cables (the “Remote Power Patent”). In August 2007, as part of a settlement agreement relating to our litigation with D-Link, we entered into a license agreement with D-Link pertaining to our Remote Power Patent (See “Legal Proceedings - D-Link Litigation”). In February 2008, we commenced patent infringement litigation against several major data networking equipment manufacturers including Cisco Systems, Inc. and 7 other defendants (See “Legal Proceedings - Pending Litigation Against Major Data Networking Equipment Manufacturers”). On August 13, 2008, as part of an agreement entered into in June 2008 with Microsemi Corp-Analog Mixed Signal Group Ltd. (“Microsemi-Analog”), previously PowerDsine Ltd., Microsemi Corporation, the parent company of Microsemi-Analog, entered into a license agreement with us for our Remote Power Patent with respect to certain of its Midspan PoE products as part of our new Special Licensing Program. As of April 15, 2009, we had entered into a total of 5 license agreements with respect to our Remote Power Patent.

At least for the next twelve months, we do not presently anticipate licensing efforts for our other patents besides our Remote Power Patent. We may seek to acquire additional patents in the future.

Our Remote Power Patent (U.S. Patent No. 6,218,930) relates to several technologies which describe a methodology for controlling the delivery of power to certain devices over an Ethernet network. Ethernet is the leading local area networking technology in use today. PoE technology allows for the delivery of power over Ethernet cables rather than by separate power cords. As a result, a variety of network devices, including IP telephones, wireless LAN Access Points, web-based network security cameras, data collection terminals and other network devices, are able to receive power over existing data cables without the need to modify the existing infrastructure to facilitate the provision of power for such devices through traditional AC outlets. Advantages of

- 1 -

PoE, such as lower installation costs, remote management capabilities, lower maintenance costs, centralized power backup, and flexibility of device location as well as the advent of worldwide power compatibility, create the possibility of PoE becoming widely adopted in networks throughout the world.

Our future success is largely dependent upon our proprietary technologies, our ability to protect our intellectual property rights and to consummate license agreements with respect to our Patent Portfolio. The complexity of patent and common law, combined with our limited resources, create risk that our efforts to protect our proprietary technologies may not be successful. We cannot be assured that our patents will be upheld or that third parties will not invalidate our patents.

Besides our Remote Power Patent, we also own five (5) additional patents covering various methodologies that provide for allocating bandwidth and establishing Quality of Service (QoS) for delay sensitive data, such as voice, on packet data networks. Quality of Service issues become important when data networks carry packets that contain audio and video which may require priority over data packets traveling over the same network. Covered within these patents are also technologies that establish bi-directional communications control channels between network-connected devices in order to support advanced applications on traditional data networks. We believe that potential licensees of the technologies contained in these patents would be vendors deploying applications that require the low latency transport of delay sensitive data such as video over data networks.

We were incorporated under the laws of the State of Delaware in July 1990. Our executive offices are located at 445 Park Avenue, Suite 1018, New York, New York 10022 and our telephone number is (212) 829-5770. Our web site can be found at http://www.network-1.com.

Pending Litigation Against Major Data Networking Equipment Manufacturers

In February 2008, we commenced litigation against several major data networking equipment manufacturers in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of our Remote Power Patent. The defendants in the lawsuit include Cisco Systems, Inc., Cisco Linksys, LLC, Enterasys Networks, Inc., 3COM Corporation, Inc., Extreme Networks, Inc., Foundry Networks, Inc., Netgear, Inc. and Adtran, Inc. We seek injunctive relief and monetary damages for infringement based upon reasonable royalties as well as treble damages for the defendant’s continued willful infringement of our Remote Power Patent. The defendants, in their answers to the Complaint, asserted that they do not infringe any valid claim of our Remote Power Patent, and further asserted that, based on several different theories, the patent claims are invalid or unenforceable. In addition to these defenses, the defendants also asserted counterclaims for, among other things, non-infringement, invalidity, and unenforceability of our Remote Power Patent. The parties are currently engaged in discovery. A Markman hearing, a hearing on claim construction of our Remote Power Patent, is currently scheduled for December, 2009 and a trial date has been set for July, 2010. In the event that the Court determines that our Remote Power Patent is not valid or enforceable, and/or that the defendants do not infringe, any such determination would have a material adverse effect on our company.

Microsemi Agreement and License

In June 2008 we entered into a new agreement with Microsemi Corp-Analog Mixed Signal Group Ltd (previously PowerDsine Ltd), a subsidiary of Microsemi Corporation (Nasdaq: MSCC), a leading manufacturer of high performance analog mixed-signal integrated circuits and high reliability semiconductors, which, among other things, amended the prior settlement agreement entered into between the parties in November 2005. In accordance with the terms of the new agreement, on August 13, 2008, Microsemi Corporation, the parent company of Microsemi-Analog, entered into a license agreement with us for our Remote Power Patent under our Special Licensing Program. The license agreement provides that Microsemi is obligated to pay us a quarterly royalty payment of 2% of the sales price for certain of its Midspan PoE products (See “Business-Licensing”).

D-Link Settlement

In August 2005, we commenced patent litigation against D-Link Corporation and D-Link Systems, Incorporated (collectively “D-Link”) in the United States District Court for the Eastern District of Texas, Tyler division, for infringement of our Remote Power Patent. Our complaint sought, among other things, a judgment that our Remote Power Patent is enforceable and has been infringed by the defendants. We also sought a permanent injunction restraining the defendants from continued infringement, or active inducement of infringement by others, of our Remote Power Patent.

In August 2007, we finalized the settlement of our patent infringement litigation against D-Link. Under the terms of the settlement, D-Link entered into a license agreement for our Remote Power Patent the terms of which include monthly royalty payments of 3.25% of the net sales of D-Link Power over Ethernet products, including those products which comply with The Institute of Electrical and Electronic Engineers (“IEEE”) 802.3af and 802.3at Standards, for the full term of our Remote Power Patent, which expires in March 2020. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of our Remote Power Patent based on units of shipments of licensed products. In addition, D-Link paid us $100,000 upon signing of the settlement agreement.

__________________________

(1) Includes non-cash compensation expense of $287,000 and $1,403,000 for the years ended December 31, 2008 and 2007, respectively.

We have incurred substantial operating losses since our inception, which have resulted in an accumulated deficit of $(50,895,000) as of December 31, 2008. For the years ended December 31, 2008 and 2007, we incurred net losses of $(1,618,000) and $(2,998,000), respectively. We have financed our operations primarily by sales of equity securities. We had royalty revenue of $349,000 and $232,000 for the years ended December 31, 2008 and December 31, 2007, respectively. Our ability to achieve revenue and generate positive cash flow from operations is dependent upon consummating additional material license agreements with respect to our patented technologies. We may not be successful in achieving additional license agreements with third parties, or in such additional license agreements resulting in significant royalty revenue, and our failure to do so would have a material adverse effect on our business, financial condition and results of operations. We believe that we will have enough funding to meet our cash needs and continue our operations until at least December 31, 2010.

RISK FACTORS

An investment in our common stock involves a high degree of risk. The risk factors listed below are those that we consider to be material to an investment in our common stock and those which, if realized, could have material adverse effects on our business, financial condition or results of operations as specifically discussed below. In such an event, the trading price of our common stock could decline, and you could lose all or part of your investment. Before you invest in our common stock, you should be aware of various risks, including those described below. You should carefully consider these risk factors, together with all of the other information included or incorporated by reference in this prospectus, before you decide whether to purchase our common stock. This section includes or refers to certain forward-looking statements. You should refer to the explanation of the qualifications and limitations on such forward-looking statements discussed on page 11.

We have a history of losses and modest revenue from current operations.

We have incurred substantial operating losses since our inception, which has resulted in an accumulated deficit of $(50,895,000) as of December 31, 2008. For the years ended December 31, 2008 and 2007, we incurred net losses of $(1,618,000) and $(2,998,000), respectively. We have financed our operations primarily by sales of equity securities. We had revenue of $349,000 and $232,000 from operations for the years ended December 31, 2008 and December 31, 2007, respectively. Our ability to achieve revenue and generate positive cash flow from operations is dependent upon consummating licensing agreements with respect to our patented technologies. In August 2007, as part of our settlement agreement pertaining to our patent infringement litigation against D-Link Corporation and D-Link Systems (collectively, “D-Link”), we entered into our first license agreement for our Remote Power Patent with D-Link. (See “Legal Proceedings - D-Link Settlement”). In August 2008, as part of our Special Licensing Program and an agreement with Microsemi Corp-Analog Mixed Signal Group Ltd. (previously PowerDsine Ltd.), a subsidiary of Microsemi Corporation (“Microsemi”), Microsemi entered into a license agreement with us for our Remote Power Patent with respect to certain of its Midspan PoE products (See “Legal Proceedings – PowerDsine Settlement). As of April 15, 2009, we have entered into 5 license agreements with respect to our Remote Power Patent. We may not be successful in achieving additional material licensing agreements with third parties and our failure to do so would have a material adverse effect on our business, financial condition and results of operations. We may not be able to achieve material revenue or generate positive cash flow from operations from our licensing business.

We could be required to stop operations if we are unable to develop our technology licensing business or raise capital when needed.

We anticipate, based on our currently proposed plans and assumptions relating to our operations (including the timetable of, costs and expenses associated with our continued operations), that our cash position of approximately $4,020,000 at March 31, 2009 will more likely than not be sufficient to satisfy our operations and capital requirements until at least December 31, 2010. However, we may expend our funds prior thereto. In the event our plans change, or our assumptions change or prove to be inaccurate (due to unanticipated expenses, difficulties, delays or otherwise), we could have insufficient funds to support our operations prior to December 31, 2010. Our inability to obtain additional financing when needed, absent generating sufficient cash from licensing

- 5 -

arrangements, would have a material adverse effect on us, requiring us to curtail or possibly cease our operations. In addition, any additional equity financing may involve substantial dilution to the interests of our then existing stockholders.

Our licensing business may not be successful.

In November 2003, we entered the technology licensing business following our acquisition of six patents relating to various telecommunications and data networking technologies including, among others, patents covering the delivery of remote power over Ethernet and the transmission of audio, video and data over computer and telephony networks. To date, we have only entered into 5 license agreements with third parties with respect to our patented technology (See “Business - Licensing”). Accordingly, we have a limited history in the technology licensing business upon which an evaluation of our prospects and future performance can be made. Our prospects must be considered in light of the risks, expenses and difficulties frequently encountered in the development, operation and expansion of a new business based on patented technologies in a highly specialized and competitive market. We may not be able to achieve sufficient revenue or profitable operations from our new licensing business.

Our future source of licensing revenue is uncertain.

In February 2004, we initiated our first licensing efforts relating to the technologies in our remote power patent (U.S. Patent No. 6,218,930) (the “Remote Power Patent”). To date, we have entered into 5 license agreements with respect to our Remote Power Patent. (See “Business - Licensing”). Our inability to consummate additional licensing agreements and achieve material revenue from our patented technologies would have a material adverse effect on our operations and our ability to continue our business. In addition, in the event we consummate license arrangements with third parties, such arrangements may not produce a stable or predictable stream of revenue in the foreseeable future. Furthermore, the success of our licensing efforts depends upon the strength of our intellectual property rights.

Our success is dependent upon our ability to protect our proprietary technologies.

Our success is substantially dependent upon our proprietary technologies and our ability to protect our intellectual property rights. We currently hold 6 patents issued by the U.S. Patent Office that relate to various telecommunications and data networking technologies and include among other things, patents covering the delivery of power to certain devices over PoE networks and the transmission of audio, voice and data over computer and telephony networks. We rely upon our patents and trade secret laws, non-disclosure agreements with our employees, consultants and third parties to protect our intellectual property rights. The complexity of patent and common law, combined with our limited resources, create risk that our efforts to protect our proprietary technologies may not be successful. We cannot assure you that our patents will be upheld or that third parties will not invalidate our patent rights. If our intellectual property rights are not upheld, such an event would have a material adverse effect on us.

- 6 -

Any litigation to protect our intellectual property or any third party claims to invalidate our patents could have a material adverse effect on our business.

Our success depends on our ability to protect our intellectual property rights. In August 2005, we commenced patent litigation against D-Link Corporation and D-Link Systems, Incorporated for infringement of our Remote Power Patent and in April 2007 we entered into a settlement agreement with the D-Link parties (See “Legal Proceedings - D-Link Litigation”). In addition, in February 2008 we commenced patent litigation against Cisco Systems, Inc. and seven other major data networking equipment manufacturers which is currently pending in the United States District Court for the Eastern District of Texas, Tyler Division (See “Legal Proceedings - Pending Litigation Against Major Data Networking Equipment Manufacturers”). In the future, it may be necessary for us to commence patent litigation against additional third parties whom we believe require a license to our patents. In addition, we may be subject to claims seeking to invalidate our patents, as asserted by the defendants in the aforementioned pending litigation in Texas with us. These types of claims, with or without merit, may subject us to costly litigation and diversion of management’s focus. If we are unsuccessful in enforcing and validating our patents and/or if third parties making claims against us seeking to invalidate our patents are successful, they may be able to obtain injunctive or other equitable relief, which effectively could block our ability to license or otherwise capitalize on our proprietary technologies. Successful litigation against us resulting in a determination that our patents are not valid or enforceable, and/or that third parties do not infringe, would have a material adverse effect on us.

Our license agreements with D-Link and Microsemi may not result in significant royalties and do not necessarily mean we will achieve additional license agreements or material revenue.

In August 2007 we finalized the settlement agreement with respect to our patent litigation against D-Link Corporation and D-Link Systems, Incorporated pending in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of our Remote Power Patent. Under the terms of the settlement, D-Link entered into a license agreement for our Remote Power Patent the terms of which include monthly royalty payments of 3.25% (which began in May 2007) of the net sales of D-Link PoE products, including those products which comply with the IEEE 802.3af and 802.3at Standards, for the full life of our Remote Power Patent, which expires in March 2020. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of the Remote Power Patent based on units of shipments of licensed products. In addition, D-Link paid us $100,000 upon signing of the Settlement Agreement. On August 13, 2008, as part of our Special Licensing Program and our agreement with Microsemi Corp-Analog Mixed Signal Group Ltd. (“Microsemi-Analog”) entered into in June 2008, Microsemi Corporation (“Microsemi”), the parent company of Microsemi-Analog, entered into a license agreement with us with respect to our Remote Power Patent. The license agreement provides that Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales price for certain of Microsemi’s Midspan PoE products for the full term of our Remote Power Patent (March 2020). For the year ended December 31, 2008, we received aggregate royalty payments of $349,000 with respect to our license agreements. Notwithstanding our license agreements with D-Link and Microsemi, there is no assurance that we will achieve significant royalty revenue from such license agreements, that we will be able to consummate additional material license agreements with third parties relating to our

- 7 -

Remote Power Patent or any of our other patents, or that such license arrangements will result in significant revenue to us.

We face uncertainty as to the outcome of our litigation against major data networking equipment manufacturers.

In February 2008, we commenced litigation against eight major data networking equipment manufacturers in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of our Remote Power Patent. The defendants in the lawsuit include Cisco Systems, Inc., Cisco Linksys, LLC, Enterasys Networks, Inc., 3COM Corporation, Inc., Extreme Networks, Inc., Foundry Networks, Inc., Netgear, Inc. and Adtran, Inc. We seek injunctive relief and monetary damages for infringement based upon reasonable royalties as well as treble damages for the defendants’ continued willful infringement of our Remote Power Patent. In their answers to the Complaint, the defendants asserted that they do not infringe any valid claim of our Remote Power Patent, and further asserted that, based on several different theories, the patent claims are invalid or unenforceable. In addition to these defenses, the defendants also asserted counterclaims for, among other things, non-infringement, invalidity, and unenforceability of our Remote Power Patent. A Markman hearing, a hearing on claim construction of our Remote Power Patent, is scheduled for December 2009 and trial date has been set for July 2010. In the event that the Court determines that our Remote Power Patent is not valid or enforceable, and/or that the defendants do not infringe, any such determination would have a material adverse effect on us.

Material licensing revenues from our Remote Power Patent may be dependent upon the applicability of the IEEE Standard.

The Institute of Electrical and Electronic Engineers (IEEE) is a non-profit, technical professional association of more than 370,000 individual members in approximately 160 countries. The Standards Association of the IEEE is responsible for the creation of global industry standards for a broad range of technology industries. In 2000, the IEEE formed a task force to facilitate the adoption of a standardized methodology for the delivery of remote power over Ethernet networks which would insure interoperability among vendors of switches and terminal devices. In June 2003, the IEEE Standards Association approved the 802.3af Power Over Ethernet standard (the “Standard”), which covers technologies deployed in delivering power over Ethernet cables including whether deployed in switches or as standalone midspan hubs both of which provide power to remote devices including, among others, wireless access points, IP phones and network based cameras. The technology is commonly referred to as PoE. We believe our Remote Power Patent covers several of the key technologies covered by the Standard. However, there is a risk that as a result of litigation a court may determine otherwise and such a determination would have a material adverse effect on our ability to enter into license agreements and achieve material revenue and profits from our Remote Power Patent.

Our markets are subject to rapid technological change and our technologies face potential technology obsolescence.

The telecommunications and data networking technology market, including transmission of audio, video and data over computer and telephony networks and the delivery of remote PoE markets, are characterized by rapid technological changes, changing customer requirements, frequent new

- 8 -

product introductions and enhancements, and evolving industry standards. The introduction of products embodying new technologies and the emergence of new industry standards may render our technologies obsolete or less marketable.

In addition, other companies may develop competing technologies that offer better or less expensive alternatives to PoE and the other technologies covered by our Patent Portfolio. Several companies have notified the IEEE that they may have patents and proprietary technologies that are covered by the Standard. In the event any of those companies asserts claims relating to our patents, the licensing royalties available to us may be limited. Moreover, technological advances or entirely different approaches developed by one or more of our competitors or adopted by various standards groups could render our Remote Power Patent obsolete, less marketable or unenforceable.

Dependence upon CEO and Chairman.

Our success is largely dependent upon the personal efforts of Corey M. Horowitz, our Chairman and Chief Executive Officer and Chairman of the Board of Directors. Our employment agreement with Mr. Horowitz expired on February 28, 2009. Mr. Horowitz continues to serve as our Chairman and Chief Executive Officer. We are currently in discussions with Mr. Horowitz with respect to a new employment agreement, but there is no certainty that we will achieve a mutually acceptable agreement. We believe that the loss of the services of Mr. Horowitz would have a material adverse effect on our business and prospects. We do not maintain key-man life insurance on the life of Mr. Horowitz.

Risks related to low priced stocks.

Our common stock currently trades on the OTC Bulletin Board under the symbol NSSI. Since the trading price of our common stock is below $5.00 per share, our common stock is considered a penny stock. SEC regulations generally define a penny stock to be an equity security that is not listed on Nasdaq or a national securities exchange and that has a market value of less than $5.00 per share, subject to certain exceptions. SEC regulations require broker-dealers to deliver to a purchaser of our common stock a disclosure schedule explaining the penny stock market and the risks associated with it. Various sales practice requirements are also imposed on broker-dealers who sell penny stocks to persons other than established customers and accredited investors (generally institutions). Broker-dealers must also provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and monthly account statements disclosing recent price information for the penny stock held in the customer’s account.

The significant number of options and warrants outstanding may adversely effect the market price for our common stock.

As of April 15, 2009, there are outstanding options and warrants to purchase an aggregate of 12,164,882 shares of our common stock at exercise prices ranging from $.12 to $10.00. To the extent that outstanding options and warrants are exercised, existing stockholder percentage ownership will be diluted and any sales in the public market of the common stock underlying such options may adversely affect prevailing market prices for our common stock.

- 9 -

We have a significant amount of authorized but unissued preferred stock, which may affect the likelihood of a change of control in our company.

Our Board of Directors has the authority, without further action by the stockholders, to issue 10,000,000 shares of preferred stock on such terms and with such rights, preferences and designations as our Board of Directors may determine. Such terms may include restricting dividends on our common stock, dilution of the voting power of our common stock or impairing the liquidation rights of the holders of our common stock. Issuance of such preferred stock, depending on the rights, preferences and designations thereof, may have the effect of delaying, deterring or preventing a change in control. In addition, certain “anti-takeover” provisions in Delaware law may restrict the ability of our stockholders to authorize a merger, business combination or change of control.

Our stock price may be volatile.

The market price of our common stock is likely to be highly volatile and could fluctuate widely in price in response to various factors, many of which are beyond our control, including the following:

● our ability to successfully enforce and/or defend our Remote Power Patent;

● our ability to enter into favorable license agreements with third parties with respect to our Remote Power Patent;

● our ability to achieve material revenue and profits;

● our ability to raise capital when needed;

● sales of our common stock;

● our ability to execute our business plan;

● technology changes;

● legislative, regulatory and competitive developments; and

● economic and other external factors.

In addition, the securities markets have from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These market fluctuations may also materially and adversely affect the market price of our common stock.

Additional stock offerings may dilute current stockholders.

We may need to issue additional shares of our capital stock or securities convertible or exercisable for shares of our capital stock, including preferred stock, options or warrants. The issuance of additional capital stock may dilute the ownership of our current stockholders.

BUSINESS

Overview

Our principal business is the acquisition, development, licensing and protection of our intellectual property. We presently own six patents issued by the U.S. Patent Office that relate to various telecommunications and data networking technologies (the “Patent Portfolio”) and include, among other things, patents covering the control of power delivery over local area networks (“LANs”) for the purpose of remotely powering network devices over Ethernet (“PoE”) networks and systems and methods for the transmission of audio, video and data over LANS in order to achieve higher quality of service (“QoS”). Our strategy is to pursue licensing and strategic business alliances with companies in industries that manufacture and sell products that make use of the technologies underlying our Patent Portfolio as well as with other users of the technologies who benefit directly from the technologies including corporate, educational and governmental entities.

To date, our efforts with respect to our Patent Portfolio have focused on licensing our patent (U.S. Patent No. 6,218,930) covering the control of power delivery over Ethernet cables (the “Remote Power Patent”). In August, 2007, as part of a settlement agreement relating to our litigation with D-Link, we entered into a license agreement with D-Link pertaining to our Remote Power Patent (See “Legal Proceedings - D-Link Settlement”). In February 2008, we commenced patent infringement litigation against several major data networking equipment manufacturers including Cisco Systems, Inc. and 7 other defendants (See “Legal Proceedings - Pending Litigation Against Major Data Networking Equipment Manufacturers”). On August 13, 2008, as part of our new agreement with Microsemi Corp - Analog Mixed Signal Group Ltd. (“Microsemi Analog”), Microsemi Corporation (“Microsemi”), the parent company of Microsemi Analog, entered into a License agreement with us with respect to our Remote Power Patent (See “Business – Licensing - Licensing Program”). As of April 15, 2009, we had entered into a total of 5 license agreements with respect to our Remote Power Patent.

At least for the next twelve months, we do not presently anticipate licensing efforts for our other patents besides our Remote Power Patent. We may seek to acquire additional patents in the future.

The Patents

Our Patent Portfolio consist of the following patents:

U.S. Patent No. 6,218,930: Apparatus and method for remotely powering access equipment over a 10/100 switched Ethernet network;

U.S. Patent No. 6,577,631: Communication switching module for the transmission and control of audio, video, and computer data over a single network fabric;

U.S. Patent No. 6,574,242: Method for the transmission and control of audio, video, and computer data over a single network fabric;

U.S. Patent No. 6,570,890: Method for the transmission and control of audio, video, and computer data over a single network fabric using Ethernet packets;

- 14 -

U.S. Patent No. 6,539,011: Method for initializing and allocating bandwidth in a permanent virtual connection for the transmission and control of audio, video, and computer data over a single network fabric; and

U.S. Patent No. 6,215,789: Local area network for the transmission and control of audio, video, and computer data.

In August 2008, we were issued European Patent No. 1086556 titled “Integrated Voice and Data Communications over a Local Area Network” which covers the same technology as covered by our U.S. QoS family of patents. The Patent has issued in France, Germany, Spain, United Kingdom and Ireland. We have also been notified that the Canadian Intellectual Property Office has issued a Notice of Allowance for this patent and we anticipate its issuance in Canada by the end of the second quarter this year.

Our future success is largely dependent upon our proprietary technologies, our ability to protect our intellectual property rights and consummate license agreements with respect to our Patent Portfolio. The complexity of patent and common law, combined with our limited resources, create risk that our efforts to protect our patents may not be successful. We cannot be assured that our patents will be upheld, or that third parties will not invalidate our patents. We face uncertainty as to the outcome of our litigation commenced in February 2008 against several major data networking equipment manufacturers pertaining to our Remote Power Patent. (See Risk Factors “We face uncertainty as to the outcome of our litigation with major data networking equipment manufacturers”).

The provisional patent application for our Remote Power Patent was filed on March 11, 1999 and the patent was granted by the U.S. Office of Patent and Trademark on April 21, 2001. The patent expires on March 11, 2020.

We were incorporated under the laws of the State of Delaware in July 1990. Our offices are located at 445 Park Avenue, Suite 1018, New York, New York 10022 and our telephone number is (212) 829-5770.

Market Overview – Remote Power Patent

Our licensing efforts are currently focused on our Remote Power Patent. Our Remote Power Patent (U.S. Patent No. 6,218,930) relates to several technologies which describe a methodology for controlling the delivery of power to certain devices over an Ethernet network.

- 15 -

midspan hubs to provide power to remote devices such as wireless access points, IP phones and network-based cameras. The technology is commonly referred to as Power over Ethernet (“PoE”). We believe that our Remote Power Patent covers several of the key technologies covered by the Standard.

Ethernet is the leading local area networking technology in use today. PoE technology allows for the delivery of power over Ethernet cables rather than by separate power cords. As a result, a variety of network devices, including IP telephones, wireless LAN Access Points, web-based network security cameras, data collection terminals and other network devices, are able to receive power over existing data cables without the need to modify the existing infrastructure to facilitate the provision of power for such devices through traditional AC outlets. Advantages such as lower installation costs, remote management capabilities, lower maintenance costs, centralized power backup, and flexibility of device location as well as the advent of worldwide power compatibility, create the possibility of PoE becoming widely adopted in networks throughout the world.

PoE provides numerous benefits including quantifiable returns on investment. The cost of hiring electricians to pull power cables to remote locations used for access points or security cameras can rival or exceed the cost of the devices. Another key benefit is the need for Voice over IP power reliability in the face of power failures. Using PoE enables data center power supply systems to ensure ongoing power – a function that would be difficult and expensive to implement if each phone required AC outlets.

These and other advantages such as remote management capabilities, lower maintenance costs, and flexibility of device location have led to forecasts that PoE will be widely adopted in networks throughout the world. The benefits of PoE are compelling as evidenced by the introduction of products by such leading vendors such as Cisco Systems, Foundry Networks, Extreme Networks, 3Com, Siemens, Nortel Networks and Avaya, as well as many others.

The ability to supply power to end-devices over Ethernet networks can be applied to other end-devices, such as advanced security cameras, RFID card readers, laptop computers, personal digital assistants and portable digital music players. As the desire to connect more end-devices to the Ethernet network grows, we believe that PoE technology will become more widely used as a method to power these end-devices.

Additional Patents

We also own five (5) additional patents, besides our Remote Power Patent, covering various methodologies that provide for allocating bandwidth and establishing QoS for delay sensitive data, such as voice, on packet data networks. QoS issues become important when data networks carry packets that contain audio and video which may require priority over data packets traveling over the same network. Covered within these patents are also technologies that establish bi-directional communications control channels between network-connected devices in order to support advanced applications on traditional data networks. We believe that potential licensees of the technologies contained in these patents would be vendors deploying applications that require the low latency transport of delay sensitive data such as video over data networks.

Network-1 Strategy

Our strategy is to capitalize on our Patent Portfolio by entering into licensing arrangements with third parties including manufacturers and users that utilize our Patent Portfolio’s proprietary technologies as well as any additional proprietary technologies covered by patents which may be acquired by us in the future. We will also seek to enter into licensing arrangements with users of the proprietary technologies, including corporate, educational and governmental entities in those cases where the patent rights extend to the users of the technologies contained in manufactured products.

We do not anticipate manufacturing products utilizing our Patent Portfolio or any of the proprietary technologies contained in our Patent Portfolio. Accordingly, we do not anticipate establishing a manufacturing, sales or marketing infrastructure. Consequently, we believe that our capital requirements will be less than the capital requirements for companies with such infrastructure requirements.

In connection with our activities relating to the protection of our Patent Portfolio, it may be necessary to assert patent infringement claims against third parties that we believe are infringing our Patent Portfolio, as is the case with our litigation against eight major data networking equipment manufacturers (“Legal Proceedings – Pending Litigation Against Major Data Networking Equipment Manufacturers”) and as we previously asserted against D-Link (See “Legal Proceedings - D-Link Settlement”).

Licensing

In February 2004, we commenced licensing efforts with respect to our Remote Power Patent. We believe that potential licensees include, among others, Wireless Local Area Networking (WLAN) equipment manufacturers, Local Area Networking (LAN) equipment manufacturers, Voice Over IP Telephony (VOIP) equipment manufacturers, and network camera manufacturers. In addition, we believe that additional potential licensees include users of the equipment embodying the PoE technology covered by our Remote Power Patent, including corporate, educational and federal, state and local government users, as we believe that they are significant beneficiaries of the technologies covered by our Remote Power Patent.

ThinkFire Agreement

On November 30, 2004, we entered into a Master Services Agreement (the “Agreement”) with ThinkFire Services USA, Ltd. (“ThinkFire”) pursuant to which ThinkFire has been granted the exclusive (except for direct efforts by us and related companies) worldwide rights to negotiate license agreements for our Remote Power Patent with respect to certain potential licensees agreed to between the parties. Either we or ThinkFire may terminate the Agreement upon 60 days notice for any reason or upon 30 days notice in the event of a material breach. We have agreed to pay ThinkFire a fee not to exceed 20% of the royalty payments received from license agreements consummated by ThinkFire on our behalf after we recover our expenses.

Licensing Program

As of April 15, 2009, we had transmitted letters to approximately 250 companies offering licenses to our Remote Power Patent. In addition, in September 2005 we initiated an industry-wide Power Up Licensing program that offered licenses for our Remote Power Patent to “early adopters” that included royalty rates and related fees at a discount from our standard royalty rates and fees for a limited time period. The Power Up licensing program continued until May 2007. No licenses were granted under the Power Up licensing program.

On June 25, 2008 we announced the introduction of a Special Licensing Program for our Remote Power Patent. We entered into 3 license agreements as part of our Special Licensing Program. Our Special Licensing Program was of limited duration (through December 31, 2008) and was implemented on an industry-wide basis to offer discounted running royalty rates and exceptions to our standard licensing terms and conditions for our Remote Power Patent to vendors of finished products that comply with the PoE Standard, including equipment defined in the PoE Standard as Power Sourcing Equipment (PSE) and Powered Devices (PD). The Special Licensing Program was available to all vendors of PoE equipment including those companies that are defendants in our pending patent litigation against eight major data networking equipment manufacturers. Our agreement with Microsemi Corp. - Analog Mixed Signal Group Ltd. (“Microsemi”), dated June 17, 2008, among other things, enabled Microsemi to assist its customers’ evaluation of our Remote Power Patent and the terms being made available to vendors of PoE equipment pursuant to our Special Licensing Program.

Microsemi License

On August 13, 2008, as part of our Special Licensing Program and our agreement with Microsemi Corp-Analog Mixed Signal Group Ltd. (“Microsemi-Analog”), previously PowerDsine Ltd, entered into in June 2008, Microsemi Corporation (“Microsemi”), the parent company of Microsemi-Analog, entered into a license agreement with us with respect to our Remote Power Patent. The license agreement provides that Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales price for certain of its Midspan PoE products for the full term of our Remote Power Patent (March 2020).

D-Link License

In August 2007, we agreed to licensing terms with D-Link Corporation and D-Link Systems (collectively, “D-Link”) as part of a settlement agreement of our patent infringement litigation against D-Link in the United States District Court for the Eastern District of Texas, Tyler Division for infringement of our Remote Power Patent (See “Legal Proceedings - D-Link Settlement”).

The license terms include the agreement by D-Link to license our Remote Power Patent for its full term which expires in March 2020, and the payment of monthly royalty payments (which began in May, 2007) based upon a running royalty rate of 3.25% of the net sales of D-Link branded Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards. The royalty rate is subject to adjustment to a royalty rate consistent with other similarly situated licensees of our Remote Power Patent that may vary according to units and volumes of licensed products sold. In addition, D-Link paid us an upfront payment upon signing of the license agreement of $100,000. The products covered by the license include D-Link Power

over Ethernet enabled switches, wireless access points, and network security cameras, among others.

Legal Representation

In February 2008, we entered into an agreement with Dovel & Luner, LLP pursuant to which such firm provides legal services to us with respect to our litigation commenced in February 2008 against eight major data networking equipment manufacturers, pending in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of our Remote Power Patent (See “Legal Proceedings”). The terms of our agreement with Dovel & Luner, LLP provide for fees of a maximum aggregate cash payment of $1.5 million plus a contingency fee of up to 24% depending upon when an outcome is achieved.

With respect to our litigation against D-Link, which was settled in May 2007, we utilized the services of Blank Rome LLP, on a full contingency basis and also the services of Potter Mitton, P.C. (Tyler, Texas) on an hourly basis to serve as local counsel. In accordance with our contingency fee agreement with Blank Rome LLP, we will pay legal fees to Blank Rome LLP equal to 25% of the royalty revenue received by us from our license agreement with D-Link after we recover our expenses related to the litigation.

Competition

The telecommunications and data networking licensing market is characterized by intense competition and rapidly changing business conditions, customer requirements and technologies. Although we believe that we have enforceable patents relating to telecommunications and data networking, there can be no assurance that our Patent Portfolio will be upheld or that third parties will not invalidate any or all of the patents in our Patent Portfolio. In addition, our current and potential competitors may develop technologies that may be more effective than our proprietary technologies or that would render our technologies less marketable or obsolete. We may not be able to compete successfully.

Description of Property

We currently lease office space in New York City at a cost of $3,400 per month under a lease which expires in June 2010.

LEGAL PROCEEDINGS

Pending Litigation Against Major Data Networking Equipment Manufacturers

In February 2008, we commenced litigation against eight major data networking equipment manufacturers in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of our Remote Power Patent. The defendants in the lawsuit include Cisco Systems, Inc., Cisco Linksys, LLC, Enterasys Networks, Inc., 3COM Corporation, Inc., Extreme Networks, Inc., Foundry Networks, Inc., Netgear, Inc. and Adtran, Inc. We seek injunctive relief and monetary damages for infringement based upon reasonable royalties as well as treble damages for the defendants’ continued willful infringement of our Remote Power Patent. The defendants, in their answers to our complaint, have asserted that they do not infringe any valid claim of our Remote Power Patent, and further asserted that, based on several different theories, the patent claims are invalid or unenforceable. In addition to these defenses, the defendants also asserted counterclaims for, among other things, non-infringement, invalidity, and unenforceability of our Remote Power Patent. A Markman hearing, a hearing on claim construction of our Remote Power Patent, is scheduled for December, 2009 and a trial date has been set for July, 2010. In the event that the Court determines that our Remote Power Patent is not valid or enforceable, and/or that the defendants do not infringe, any such determination would have a material adverse effect on our company.

D-Link Settlement

In August 2007, we finalized the settlement of our patent infringement litigation against D-Link. Under the terms of the settlement, D-Link entered into a license agreement for our Remote Power Patent the terms of which include monthly royalty payments of 3.25% of the net sales of D-Link Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards, for the full term of our Remote Power Patent, which expires in March 2020. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of our Remote Power Patent based on units of shipments of licensed products. In addition, D-Link paid us $100,000 upon signing of the Settlement Agreement.

- 20 -

PowerDsine Settlement

On November 16, 2005, we entered into a Settlement Agreement with PowerDsine, Inc. (NASDAQ: PDSN) and PowerDsine Ltd. (collectively, “PowerDsine”) which dismissed, with prejudice, patent litigation brought by PowerDsine against us in March 2004 in the United States District Court for the Southern District of New York that sought a declaratory judgment that our Remote Power Patent (U.S. Patent No. 6,218,930) was invalid and not infringed by PowerDsine and/or its customers.

Under the terms of the Settlement Agreement, we agreed that, under certain circumstances, we will not initiate litigation against PowerDsine for its sale of Power over Ethernet (PoE) integrated circuits. In addition, we agreed that we will not seek damages for infringement from customers that incorporate PowerDsine integrated circuit products in PoE capable Ethernet switches manufactured on or before April 30, 2006. PowerDsine has agreed that it will not initiate, assist or cooperate in any legal action relating to the Remote Power Patent.

No licenses to use the technologies covered by our Remote Power Patent were granted to PowerDsine or its customers under the terms of the settlement. The Settlement Agreement further provides that PowerDsine is obligated to provide each of its customers with written notice of the settlement which notice shall disclose that no license for our Remote Power Patent has been provided to PowerDsine’s customers and that in order to combine, modify or integrate any PowerDsine product with or into any other device or software, PowerDsine’s customers may need to receive patent license(s) for our Remote Power Patent which is the customer’s responsibility.

In June 2008 we entered into a new agreement with Microsemi Corp-Analog Mixed Signal Group Ltd (“Microsemi Analog”), previously PowerDsine Ltd, a subsidiary of Microsemi Corporation (“Microsemi”), a leading manufacturer of high performance analog mixed-signal integrated circuits and high reliability semiconductors, which, among other things, amended the prior Settlement Agreement entered into between the parties in November 2005. Under the new agreement, on June 25, 2008 we announced the commencement of an industry-wide Special Licensing Program for our Remote Power Patent to vendors of PoE equipment. The Special Licensing Program was of limited duration (through December 31, 2008) and was implemented on an industry-wide basis to offer discounted running royalty rates and exceptions to our standard licensing terms and conditions for the Remote Power Patent to PoE vendors who were “early adopters” and entered into license agreements without delay to avoid litigation and higher royalties. We entered into 3 license agreements as part of our Special Licensing Program. The new agreement enabled Microsemi Analog to assist in its customers’ evaluation of our Remote Power Patent and the terms being made available to vendors of PoE equipment pursuant to our Special Licensing Program, an activity that was previously prohibited by the 2005 Settlement Agreement with PowerDsine. As part of our Special Licensing Program and our agreement with Microsemi Analog entered into in June 2008, Microsemi entered into a license agreement, on August 13, 2008, with us with respect to our Remote Power Patent. The license agreement provides that Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales price for certain of Microsemi’s Midspan PoE products for the full term of our Remote Power Patent (March 2020).

PLAN OF DISTRIBUTION

This offering is self-underwritten; neither we nor the selling stockholders have employed an underwriter for the sale of common stock by the selling stockholders. We will bear all expenses in connection with the preparation of this prospectus. The selling stockholders will bear all expenses associated with the sale of their common stock including commissions and brokerage fees.

The selling stockholders may offer their shares of common stock directly or through pledgees, donees, transferees or other successors in interest in one or more of the following transactions:

·	ordinary brokerage transactions in which the broker-dealer solicits purchasers;

·	block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

·	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

·	an exchange distribution in accordance with the rules of the applicable exchange;

·	privately negotiated transactions;

·	broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

·	a combination of any such methods of sale; and

·	any other method permitted pursuant to applicable law.

The selling stockholders may offer their shares of common stock at any of the following prices:

·	fixed prices that may be changed;

·	market prices prevailing at the time of sale;

·	prices related to such prevailing market prices; and

·	at negotiated prices.

The selling stockholders may effect transactions by selling shares to or through broker-dealers, and all such broker-dealers may receive compensation in the form of discounts, concessions, or commissions from the selling stockholders and/or the purchasers of shares of common stock for whom such broker-dealers may act as agents or to whom they sell as

- 33 -

principals, or both (which compensation as to a particular broker-dealer might be in excess of customary commissions).

Any broker-dealer acquiring common stock from the selling stockholders may sell the shares either directly, in its normal market-making activities, through or to other brokers on a principal or agency basis or to its customers. Any such sales may be at prices then prevailing on the OTC Bulletin Board or at prices related to such prevailing market prices or at negotiated prices to its customers or a combination of such methods. The selling stockholders and any broker-dealers that act in connection with the sale of the common stock hereunder may be deemed to be “underwriters” within the meaning of Section 2(11) of the Securities Act; any commission received by them and any profit on the resale of shares as principal might be deemed to be underwriting discounts and commissions under the Securities Act. Any such commissions, as well as other expenses incurred by the selling stockholders and applicable transfer taxes, are payable by the selling stockholders.

The selling stockholders reserve the right to accept, and together with any agent of the selling stockholder, to reject in whole or in part any proposed purchase of the shares of common stock. The selling stockholders will pay any sales commissions or other seller’s compensation applicable to such transactions.

We have not registered or qualified offers and sales of shares of the common stock under the laws of any country other than the United States. To comply with certain states’ securities laws, if applicable, the selling stockholders will offer and sell their shares of common stock in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the selling stockholders may not offer or sell shares of common stock unless we have registered or qualified such shares for sale in such states or we have complied with an available exemption from registration or qualification.

Any shares of common stock offered under this prospectus that qualify for sale pursuant to Rule 144 of the Securities Act may also be sold under Rule 144 rather than pursuant to this prospectus.

The selling stockholders with respect to any purchase or sale of shares of common stock are required to comply with Regulation M promulgated under the Securities Exchange Act of 1934, as amended. In general, Rule 102 under Regulation M prohibits any person connected with a distribution of securities (the “Distribution”) from directly or indirectly bidding for, or purchasing for any account in which he or she has a beneficial interest, any of such securities or any right to purchase such securities, for a period of one business day before and after completion of his or her participation in the Distribution (we refer to that time period as the “Distribution Period”).

During the Distribution Period, Rule 104 under Regulation M prohibits the selling stockholders and any other persons engaged in the Distribution from engaging in any stabilizing bid or purchasing of our common stock except for the purpose of preventing or retarding a decline in the open market price of our common stock. No such person may effect any stabilizing transaction to facilitate any offering at the market. Inasmuch as the selling shareholders will be reoffering and reselling our common stock at the market, Rule 104 prohibits

- 34 -

them from effecting any stabilizing transaction in contravention of Rule 104 with respect of our common stock.

There can be no assurance that the selling stockholders will sell any or all of the shares offered by them hereunder or otherwise.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH OUR FINANCIAL STATEMENTS, INCLUDING THE NOTES THERETO, INCLUDED ELSEWHERE IN THIS PROSPECTUS. EXCEPT FOR THE HISTORICAL INFORMATION CONTAINED HEREIN, THIS DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES, INCLUDING, BUT NOT LIMITED TO, THOSE DISCUSSED IN THE SECTION HEREIN ENTITLED “RISK FACTORS” OF THIS PROSPECTUS AS WELL AS THOSE RISKS DISCUSSED IN THIS SECTION AND ELSEWHERE IN THIS PROSPECTUS. BECAUSE SUCH STATEMENTS INVOLVE RISKS AND UNCERTAINTIES, ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THOSE EXPRESSED OR IMPLIED BY SUCH FORWARD-LOOKING STATEMENTS.

Overview

Our principal business is the acquisition, development, licensing and protection of our intellectual property. We presently own six patents covering various telecommunications and data networking technologies (the “Patent Portfolio”) including, among others, patents covering the delivery of power over Ethernet for the purpose of remotely powering network devices, and the transmission of audio, video and data over computer and telephony networks. Our strategy is to pursue licensing and strategic business alliances with companies in the industries that manufacture and sell products that make use of the technologies underlying our patents as well as with other users of the technology who benefit directly from the technology including corporate, educational and governmental entities.

To date, our efforts with respect to our Patent Portfolio have focused on licensing our patent (U.S. Patent No. 6,218,930) covering the control of power delivery over Ethernet cables (the “Remote Power Patent”). As of April 15, 2009, we had entered into 5 license agreements with respect to our Remote Power Patent. In August, 2007, as part of a settlement agreement relating to our litigation with D-Link, we entered into a license agreement with D-Link pertaining to our Remote Power Patent (See “Business – Licensing - D-Link License”). In February 2008, we commenced patent infringement litigation against several major data networking equipment manufacturers including Cisco Systems, Inc. and seven other defendants (See “Legal Proceedings”). During the next 12 months we do not presently anticipate licensing efforts for our other patents besides our Remote Power Patent.

To date we have incurred significant losses and at December 31, 2008 had an accumulated deficit of $(50,895,000). For the year ended December 31, 2008 and December 31, 2007, we incurred net losses of $(1,618,000) and $(2,998,000), respectively. We anticipate that we will

- 35 -

continue to incur losses until we enter into additional license agreements with respect to our patented technologies. We have achieved revenue of $349,000 from our technology licensing business for the year ended December 31, 2008 with respect to royalties pertaining to our Remote Power Patent. Our inability to consummate additional material license agreements and achieve revenue from our patented technologies would have a material adverse effect on our operations and our ability to continue business.

Our success and ability to generate revenue is largely dependent on our ability to consummate licensing arrangements with third parties. In November 2004, we entered into an agreement with ThinkFire Services USA, Ltd. (“ThinkFire”) pursuant to which ThinkFire has been granted the exclusive worldwide rights to negotiate license agreements for our Remote Power Patent with certain agreed-upon potential licensees. We have agreed to pay ThinkFire a fee of up to 20% of the royalty payments received from license agreements consummated by ThinkFire on our behalf after we recover our expenses.

In August 2007 we finalized the settlement of our patent litigation against D-Link in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of our Remote Power Patent (U.S. Patent No. 6,218,930). Under the terms of the settlement, D-Link has agreed to license our Remote Power Patent the terms of which include monthly royalty payments of 3.25% of the net sales of D-Link branded Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards, for the full life of our Remote Power Patent, which expires in March 2020. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of our Remote Power Patent based on units of shipments of licensed products. In addition, D-Link paid us $100,000 upon signing the settlement agreement. Notwithstanding the settlement and our license agreement with D-Link, there is no assurance that we will achieve significant royalty revenue from D-Link, that we will be able to achieve additional license agreements with third parties relating to our Remote Power Patent or our other patents, or that such license arrangements will result in material revenue to us.

In February 2008, we commenced litigation against eight major data networking equipment manufacturers in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of our Remote Power Patent. The defendants in the lawsuit include Cisco Systems, Inc., Cisco Linksys, LLC, Enterasys Networks, Inc., 3COM Corporation, Inc., Extreme Networks, Inc., Foundry Networks, Inc., Netgear, Inc. and Adtran, Inc. We seek injunctive relief and monetary damages for infringement, based upon reasonable royalties as well as treble damages for the defendants’ continued willful infringement of our Remote Power Patent. All of the defendants have answered our complaint and asserted that they do not infringe any valid claim of our Remote Power Patent, and further asserted that, based on several different theories, the patent claims are invalid or unenforceable. In addition to these defenses, the defendants also asserted counterclaims for, among other things, non-infringement, invalidity, and unenforceability of our Remote Power Patent. In the event that the Court determines that our Remote Power Patent is not valid or enforceable, and/or that the defendants do not infringe, any such determination would have a material adverse effect on us.

As part of our Special Licensing Program and our agreement with Microsemi Corp-Analog Mixed Signal Group Ltd. (“Microsemi-Analog”) entered into in June 2008, Microsemi Corporation (“Microsemi”), the parent company of Microsemi-Analog, entered into a license agreement, dated August 13, 2008, with us with respect to the Remote Power Patent. The license agreement provides

- 36 -

that Microsemi is obligated to pay us quarterly royalty payments of 2% of the sales price for certain of Microsemi’s Midspan PoE products for the full term of the Remote Power Patent (through March 2020).

RESULTS OF OPERATIONS

Year Ended December 31, 2008 Compared To Year Ended December 31, 2007

We had revenues of $349,000 for the year ended December 31, 2008 (“2008”) as compared to revenues of $232,000 for the year ended December 31, 2007 (“2007”) which increase in revenues was attributed to a full year of royalties with respect to our license with D-Link and royalties from our license with Microsemi entered into in August 2008.

We had a cost of royalties of $18,000 and $12,000 for 2008 and 2007, respectively, which was related to the payment of bonus compensation on the royalties pursuant to an employment agreement with our Chief Executive Officer. The gross profit for 2008 was $331,000 as compared to $220,000 for 2007.

General and administrative expenses include overhead expenses, finance, accounting, legal and other professional services incurred by us. General and administrative expenses decreased by $219,000, from $1,992,000 for 2007 to $1,773,000 for 2008 due primarily to decreased fees and expenses with respect to litigation involving our Remote Power Patent.

We incurred an operating loss of ($1,729,000) for 2008 compared with an operating loss of ($3,175,000) for 2007. Included in the operating loss for 2008 was $287,000 in charges relating to non-cash compensation expenses as compared to $1,403,000 for such non-cash compensation expenses for 2007. These losses were offset by interest earned of $111,000 and $177,000 for 2008 and 2007, respectively.

No provision for or benefit from federal, state or foreign income taxes was recorded for 2008 and 2007 because we incurred net operating losses and fully reserved our deferred tax assets as their future realization could not be determined.

As a result of the foregoing, we incurred a net loss of $(1,618,000) for the 2008 compared with a net loss of $(2,998,000) for 2007.

LIQUIDITY AND CAPITAL RESOURCES

We have financed our operations primarily from the sale of equity securities. In April 2007, we completed a private offering of equity securities resulting in gross proceeds of $5,000,000. In addition, during the fourth quarter of 2007 we received $1,184,375 of cash proceeds from the exercise of warrants issued in December 2004 and January 2005. We anticipate, based on currently proposed plans and assumptions, relating to our operations, that our cash and cash equivalents of approximately $4,020,000 as of March 31, 2009 will more likely than not be sufficient to satisfy our operations and capital requirements until at least December 31, 2010. There can be no assurance, however, that such funds will not be expended prior thereto. In the event our plans change, or our assumptions change, or prove to be inaccurate (due to unanticipated expenses, difficulties, delays or otherwise), we may have insufficient funds

- 37 -

to support our operations prior to December 31, 2010. Our inability to consummate licensing arrangements with respect to our Remote Power Patent and generate revenues therefrom on a timely basis or obtain additional financing when needed would have a material adverse effect on our company, requiring us to curtail or cease operations. In addition, any equity financing may involve substantial dilution to our current stockholders.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any off-balance sheet arrangements.

CONTRACTUAL OBLIGATIONS

We do not have any long-term debt, capital lease obligations, operating lease obligations, purchase obligations or other long-term liabilities.

Critical Accounting Policies:

Patents:

We own a patent portfolio that relates to various telecommunications and data networking technologies. We capitalize the costs associated with acquisition, registration and maintenance of the patents and amortize these assets over their remaining useful lives on a straight-line basis. Any further payments made to maintain or develop the patents would be capitalized and amortized over the balance of the useful life for the patents.

Impairment of long-lived assets:

In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”, we record impairment losses on long-lived assets used in operations or expected to be disposed of when indicators of impairment exist and the cash flows expected to be derived from those assets are less than carrying amounts of those assets.

Use of estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Narrative Disclosure to Summary Compensation Table

Employment Agreements, Termination of Employment and Change-In-Control Arrangements

On February 28, 2007, we entered into a new Employment Agreement with Corey M. Horowitz pursuant to which Mr. Horowitz continued to serve as our Chairman and Chief Executive Officer for a two year term at an annual base salary of $288,750 for the first year, increasing by 5% for the second year. In connection with his employment agreement, Mr. Horowitz was issued a five (5) year option to purchase 375,000 shares of our common stock at an exercise price of $1.46 per share which vested, on a quarterly basis over a one year period subject to acceleration upon a change of control. We also issued to Mr. Horowitz on the one year anniversary date (February 28, 2008) an additional five (5) year option to purchase 375,000 shares of our common stock at an exercise price of $1.32 (the closing price of our common stock on the date of grant), which option vested on a quarterly basis over a one year period. In addition to the aforementioned option grants, the Company agreed to extend for an additional three (3) years the expiration dates of all options and warrants (an aggregate of 2,620,000 shares) expiring in calendar year 2007 and 2008 owned by Mr. Horowitz and CMH Capital Management Corp. (“CMH”), an affiliate. Under the terms of his Employment Agreement, Mr. Horowitz receives bonus compensation in an amount equal to 5% of our royalties or other payments (before deduction of payments to third parties including, but not limited to, legal fees and expenses and third party license fees) received from licensing its patents (including patents currently owned and acquired or licensed on an exclusive basis during the period in which Mr. Horowitz continues to serve as an executive officer of our company) (the “Royalty Bonus Compensation”). During 2008, Mr. Horowitz received $18,000 of Royalty Bonus Compensation. Mr. Horowitz shall also receive bonus compensation equal to 5% of the gross proceeds from (i) the sale of any of our patents or (ii) our merger with or into another corporation or entity. The Royalty Bonus Compensation shall continue to be paid to Mr. Horowitz for the life of each of our patents with respect to licenses entered into by us with third parties during Mr. Horowitz’s term of employment or at anytime thereafter, whether Mr. Horowitz is employed by us or not, provided, that, Mr. Horowitz’s employment (during the term of the Employment

- 43 -

Agreement) has not been terminated by us “For Cause” (as defined) or terminated by Mr. Horowitz without “Good Reason” (as defined). In the event that Mr. Horowitz’s employment is terminated by us “Other Than For Cause” (as defined) or by Mr. Horowitz for “Good Reason” (as defined), Mr. Horowitz shall be entitled to a severance of 12 months base salary.

In accordance with his employment agreement, Mr. Horowitz also had certain anti-dilution rights which provided that if at any time during the period ended December 31, 2008, in the event that we completed an offering of our common stock or any securities convertible or exercisable into common stock (exclusive of securities issued upon exercise of outstanding options, warrants or other convertible securities), Mr. Horowitz shall receive from us, at the same price as the securities issued in the financing, such number of additional options to purchase common stock so that he maintains the same derivative ownership percentage (21.47%) of our company based upon options and warrants owned by Mr. Horowitz and CMH (exclusive of ownership of shares of common stock by Mr. Horowitz and CMH) as he owned as of the time of execution of his employment agreement; provided, that, the aforementioned anti-dilution protection was afforded to Mr. Horowitz up to a maximum financing(s) of $2.5 million. In April 2007, with respect to our completion of a $5.0 million private offering and in accordance with the aforementioned anti-dilution provisions of his employment agreement, Mr. Horowitz was issued a five (5) year option to purchase 732,709 shares of our common stock, at an exercise price of $1.67 per share (the exercise price was reduced to $0.68 per share in March 2009 as part of our Board of Directors approval of adjustment of exercise prices of compensatory options and warrants to purchase up to an aggregate of 5,029,945 shares – See “Certain Relationships and Related Transactions).

On February 28, 2009, our employment agreement with Mr. Horowitz expired. We are in discussions with Mr. Horowitz with respect to a new employment agreement; however, there is no certainty that a mutually acceptable agreement will be reached. Mr. Horowitz continues to serve as our Chairman and Chief Executive Officer. We believe that the loss of the services of Mr. Horowitz would have a material adverse effect on our business and prospects. (See Risk Factors – “Dependence Upon CEO and Chairman”).

On December 18, 2008, we entered into an agreement with David C. Kahn pursuant to which he continues to serve as our Chief Financial Officer through December 31, 2010. In consideration for his services, Mr. Kahn is compensated at the rate of $7,292 per month for the year ended December 31, 2009 and will be compensated at the rate of $7,657 per month for the year ended December 31, 2010. In connection with the agreement, Mr. Kahn was also issued a five (5) year option to purchase 100,000 shares of our common stock at an exercise price of $0.54 per share. The option vested 40,000 shares on the date of grant and the balance of the shares (60,000) vest on a quarterly basis in equal amounts of 7,500 shares beginning March 31, 2009 through December 31, 2010. Upon a “Change in Control” (as defined) all of the unvested shares underlying the option shall become 100% vested and immediately exercisable. The agreement further provides that we may terminate the agreement at any time for any reason. In the event Mr. Kahn’s services are terminated without “Good Cause” (as defined), he will be entitled to accelerated vesting of all unvested shares underlying the Option and the lesser of (i) six months base monthly compensation or (ii) the remaining balance of the monthly compensation payable through December 31, 2010.

- 44 -

Director Compensation

We compensated each director, who is not an employee of our company, by granting to each such outside director (upon joining the Board) stock options to purchase 50,000 shares of our common stock, at an exercise price equal to the closing price of our common stock on the date of grant, with the options vesting over a one year period in equal quarterly amounts. In addition, subject to the discretion of the Compensation Committee and the Board of Directors, each non-employee director is eligible to receive option grants for each year of service as a director. In December 2007, for services as a director for 2008, each member of the Board of Directors (with the exception of Harry Schessel who resigned in December 2007) was granted a five (5) year option to purchase 25,000 shares at an exercise price of $1.45 per share (closing price of our common stock on the date of grant), which option vested on a monthly basis over a one year period, subject to continued service on the Board of Directors. In December 2008, for services as a Director for 2009, each member of the Board of Directors was granted a five (5) year option to purchase 25,000 shares at an exercise price of $0.51 per share (closing price of our common stock on the date of grant) which option vests on a monthly basis over a one year period subject to continued service on the Board of Directors.

The following table sets forth the compensation paid to all persons who served as members of our board of directors (other than our Named Executive Officers) during the year ended December 31, 2008. No director who is also a Named Executive Officer received any compensation for services as a director in 2008.

Mr. Graifman resigned as a Board member on June 23, 2008.

(2) In determining the grant date fair value of the option grants in January 2008 under SFAS No. 123R, we made the following assumptions: expected term of the options – five years; risk free interest rate for the expected term of the options – 3.28%; expected volatility of the underlying stock – 37.32%; no expected dividends.

(3) Does not include the fair value of options to purchase 25,000 shares of our common stock granted on December 1, 2008 to each of Robert Pons and Laurent Ohana since the options vest on a quarterly basis beginning March 1, 2009.

DESCRIPTION OF SECURITIES

Our authorized capital stock consists of 50,000,000 shares of common stock, par value $.01 per shares, and 10,000,000 shares of preferred stock, par value $.01 per share. As of the date of this Prospectus, we have outstanding 24,135,557 shares of common stock and no outstanding shares of preferred stock.

Common Stock

Holders of our common stock are entitled to one vote per share on all matters submitted to a vote of stockholders. There are no cumulative voting rights for the election of directors, which means that the holders of more than 50% of such outstanding shares voting for the election of directors can elect all of the directors standing for election. Subject to the rights of any outstanding class or series of preferred stock created by the authority of our Board of Directors, holders of common stock are entitled to receive dividends as and when declared by our Board of Directors out of funds legally available therefor. Subject to the rights of any outstanding class or series of preferred stock created by the authority of our Board of Directors, in the event of the liquidation, dissolution or winding up of our company, the holder of each share of common stock is entitled to share equally in the balance of any of the assets of our company available for distribution to stockholders. Outstanding shares of common stock do not have subscription or conversion rights and there are no redemption or sinking fund provisions applicable thereto. Holders of common stock have no preemptive rights to purchase pro-rata portions of newly issued common stock or preferred stock.

Preferred Stock

Our Board is authorized, subject to any limitations prescribed by Delaware law, to provide for the issuance of additional shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon, and to increase or decrease the number of shares of any such series (but not below the number of shares of such series then outstanding), without any further vote or action by the stockholders. Our Board may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. Thus, the issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of our company. Our company has no current plan to issue any shares of preferred stock.

Warrants and Options

As of the date of this prospectus, there are outstanding options and warrants to purchase an aggregate of 12,164,882 shares of our common stock at exercise prices ranging from $.12 to $10.00. To the extent that outstanding options and warrants are exercised, stockholder percentage ownership will be diluted and any sales in the public market of the common stock underlying such options and warrants may adversely affect prevailing market prices for our common stock.

With respect to our $5,000,000 private offering completed on April 16, 2007, we issued to ten (10) investors five (5) year warrants to purchase an aggregate of 1,666,667 shares of common stock, at an exercise price of $2.00 per share, which underlying shares are being registered for resale in this Prospectus pursuant to a registration rights agreement with such investors. On March 11, 2009, our Board of Directors adjusted the exercise price of the warrants to $1.75 per share ($1.25 per share if the warrants are executed anytime up to and including December 31, 2008).

With respect to our $2,685,000 private placement completed in December 2004 and January 2005, we issued warrants to purchase an aggregate of 2,013,750 shares of common stock.

DISCLOSURE OF COMMISSION POSITION ON

INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Our Certificate of Incorporation and Bylaws provide our directors with protection for breaches of their fiduciary duties to us and our shareholders. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us, we have been advised that it is the SEC’s opinion that such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

In the event that a claim for indemnification against such liabilities (other than the payment by us of expenses incurred or paid by a director, officer or controlling person in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of our counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

WHERE YOU CAN FIND MORE INFORMATION

We file annual, quarterly and current reports and other information with the SEC. You may read and copy any document we file at the SEC’s Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549 on official business days during the hours of 10:00 a.m. – 3:00 p.m. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. Our SEC filings are also available to you on the SEC’s Internet site at http://www.sec.gov.

This prospectus is part of a Post-Effective Amendment on Form S-1 to Form SB-2 and Form S-2 Registration Statement filed by us with the SEC under the Securities Act and therefore omits certain information in the Registration Statement. We have also filed exhibits with the Registration Statement that are not included in this Prospectus, and you should refer to the applicable exhibit for a complete description of any statement referring to any document. You can inspect a copy of the Registration Statement and its exhibits, without charge, at the SEC’s Public Reference Room, and can copy such material upon paying the SEC’s prescribed rates.

Notes to Financial Statements

December 31, 2008 and 2007

Note A - The Company

Network-1 Security Solutions, Inc. (the “Company”) is engaged in the acquisition, licensing and protection of its intellectual property and proprietary technologies. The Company owns six patents covering various telecommunications and data networking technologies (the “Patent Portfolio”) and includes, among other things, patents covering the control of power delivery over Ethernet networks for the purpose of remotely powering network devices and systems and methods for the transmission of audio, video and data over local area networks (LANS) in order to achieve higher quality of service (QoS). The Company’s strategy is to pursue licensing and strategic business alliances with companies that manufacture and sell products that make use of the technologies underlying the Patent Portfolio as well as with other users of the technologies who benefit directly from the technologies including corporate, educational and governmental entities. To date, the Company’s efforts with respect to its Patent Portfolio have focused on licensing its patent (U.S. Patent No. 6,218,930) covering the control of power delivery over Ethernet cables (the “Remote Power Patent”). At least for the next twelve months, the Company does not currently anticipate licensing efforts for its other patents besides its Remote Power Patent. The Company may seek to acquire additional patents in the future.

Note B –Summary of Significant Accounting Policies

[1]	Cash equivalents:

The Company considers all highly liquid short-term investments purchased with an original maturity of three months or less to be cash equivalents.

[2]	Revenue recognition:

The Company recognizes revenue received from the licensing of its intellectual property portfolio in accordance with Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB No. 104”) and related authoritative pronouncements. Under this guidance, revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been performed pursuant to the terms of the license agreement, (iii) amounts are fixed or determinable and (iv) collectability of amounts is reasonably assured.

[3]

Patents:

The Company owns a Patent Portfolio that relates to various telecommunications and data networking technologies. The Company capitalizes the costs associated with acquisition, registration and maintenance of the patents and amortizes these assets over their remaining useful lives on a straight-line basis. Any further payments made to maintain or develop the patents would be capitalized and amortized over the balance of the useful life of the patents.

[4]	Impairment of long-lived assets:

In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” intangible assets with finite lives are tested for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable. Accordingly, the Company records impairment losses on long-lived assets used in operations or expected to be disposed of when indicators of impairment exist and the undiscounted cash flows expected to be derived from those assets are less than carrying amounts of those assets. During the years ended December 31, 2008 and 2007, there was no impairment to its patents.

[5]	Income taxes:

The Company utilizes the liability method of accounting for income taxes. Under such method, deferred tax assets and liabilities are recognized for the future tax consequences

F-6

NETWORK-1 SECURITY SOLUTIONS, INC.

Notes to Financial Statements

December 31, 2008 and 2007

Note B – Summary of Significant Accounting Policies (continued)

attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect at the balance sheet date. The resulting asset or liability is adjusted to reflect enacted changes in tax law. Deferred tax assets are reduced, if necessary, by a valuation allowance when the likelihood of realization is not assured.

[6]	Net Loss per share:

Basic net loss per share is calculated by dividing the net loss by the weighted average number of outstanding common shares during the year. Diluted per share data includes the dilutive effects of options, warrants and convertible securities. Potential common shares of 12,164,882 and 11,553,356 at December 31, 2008 and 2007, respectively, are not included in the calculation of diluted loss per share because its effect will be anti-dilutive. Such potential common shares are options and warrants.

[7]	Use of estimates:

[8]	Financial instruments:

The carrying amounts of cash and cash equivalents, accounts payable and accrued expenses approximate their fair value due to the short period to maturity of these instruments.

[9]	Stock-based compensation:

Effective January 1, 2006, the Company adopted SFAS No. 123 (revised 2004), Share Based Payment, or SFAS 123(R), which is a revision of Statement No. 123 (“SFAS 123”) Accounting for Stock Based Compensation. SFAS 123(R) supersedes Accounting Principles Board (“APB”) No. 25, Accounting for Stock Issued to Employees (“APB 25”), and amends Financial Accounting Standards Board (“FASB”) Statement No. 95 Statement of Cash Flows. SFAS 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values.

Notes to Financial Statements

December 31, 2008 and 2007

[10]	Recently issued accounting standards:

In December 2007, the FASB issued SFAS No. 141R, Business Combinations, which replaces SFAS No. 141. The statement retains the purchase method of accounting for acquisitions, but requires a number of changes, including changes in the way assets and liabilities are recognized in the purchase accounting. It also changes the recognition of assets acquired and liabilities assumed arising from contingencies, requires the capitalization of in-process research and development at fair value, and requires the expensing of acquisition-related costs as incurred. SFAS No. 141R is effective for fiscal year beginning after December 15, 2008 and the Company believes the adoption of SFAS No. 141R will not have a material impact on its financial statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements – an amendment of ARB No. 51, which changes the accounting and reporting for minority interests. Minority interests will be recharacterized as noncontrolling interests and will be reported as a component of equity separate from the parent’s equity, and purchases or sales of equity interests that do not result in a change in control will be accounted for as equity transactions. In addition, net income attributable to the noncontrolling interest will be included in net income and, upon a loss of control, the interest sold, as well as any interest retained, will be recorded at fair value with any gain or loss recognized in net income. SFAS No. 160 is effective for fiscal year beginning after December 15, 2008. The Company believes the adoption of SFAS No. 160 will not have a material impact on our financial statements.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities – an amendment of FASB Statement No. 133, which requires additional disclosures about the objectives of derivative instruments and hedging activities, the method of accounting for such instruments under SFAS No. 133 and its related interpretations, and a tabular disclosure of the effects of such instruments and related hedged items on our financial position, financial performance, and cash flows. SFAS No. 161 is effective for fiscal year beginning after December 15, 2008. The Company believes the adoption of SFAS No. 161 will not have a material impact on our financial statements.

In February 2008, the FASB issued FASB Staff Position 157-2, Effective Date of FASB Statement No. 157, which delays the effective date of SFAS No. 157 to fiscal years beginning after November 15, 2008, for all nonfinancial assets and nonfinancial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). The Company believes the adoption of the delayed items of SFAS No. 157 will not have a material impact on our financial statements.

Note C- Patents

In November 2003, the Company acquired a portfolio of telecommunications and data networking patents (six patents) from Merlot Communications, Inc. (the “Seller”) in which certain principal stockholders of the Company owned a majority of the Seller’s voting stock at the time of the transaction. The purchase price for the Patent Portfolio was $100,000, paid in cash. As additional consideration for the purchase, the Company granted the Seller a nonexclusive, royalty free, perpetual license for the term of each patent to use the patents for the development, manufacture or sale of its own branded products to end users. The cash price paid has been capitalized and is being amortized over the remaining useful life of each patent. The Company had agreed to pay the Seller 20% of the net income, as defined, after the first $4,000,000 of net income realized by the Company on a per patent basis from the sale or licensing of the patents. On January 18, 2005, the Company and Seller amended the Patent Purchase Agreement (the “Amendment”) pursuant to which the Company paid additional purchase price of $500,000 to Seller in consideration for the restructuring of future contingent payments to Seller from the licensing or sale of the Patents. Such $500,000 has been recorded as an expense in the accompanying statement of operations. The Amendment provides for future contingent payments by the Company to Seller of $1.0 million upon achievement of $25 million of Net Royalties (as defined), an additional $1.0 million upon achievement of $50 million of Net Royalties and an additional $500,000 upon achievement of $62.5 million of Net Royalties from licensing or sale of the patents acquired from Merlot. Amortization expense amounted to $7,000 each for the years ended December 31, 2008 and December 31, 2007.

Note D - Stockholders’ Equity

[1]	Private Placement:

On April 16, 2007, the Company sold in a private placement 3,333,333 shares of common stock at a price of $1.50 per share or an aggregate purchase price of $5,000,000 and five (5) year warrants to purchase 1,666,667 shares of common stock, at an exercise price of $2.00 per share. In connection with the private placement the Company paid placement agent fees of $275,000 and issued warrants to purchase an aggregate of 360,000 shares of common stock (240,000 shares exercisable at $1.50 per share and 120,000 shares exercisable at $2.00 per share).

[2]	Stock options:

During 1996, the Board of Directors and stockholders approved the adoption of the 1996 Stock Option Plan (the “1996 Plan”). The 1996 Plan, as amended, provided for the granting of both incentive and non-qualified options to purchase common stock of the Company. A total of 4,000,000 were eligible to be issued under the 1996 Plan. As of March 2006, in accordance with the terms of the plan, no further options were eligible to be issued under the Plan.

The term of options granted under the 1996 Plan may not exceed ten years (five years in the case of an incentive stock option granted to an employee/director owning more than 10% of the voting stock of the Company) (“10% stockholder”). The option price for incentive stock options cannot be less than 100% of the fair market value of the shares of common stock at the time the option is granted (110% for a 10% stockholder). Option terms and vesting periods were set by the Compensation Committee in its discretion.

Note J – Litigation

[1]

In February 2008, the Company commenced litigation against several major data networking equipment manufacturers in the United States District Court for the Eastern District of Texas, Tyler Division, for infringement of the Company’s Remote Power Patent. The defendants in the lawsuit include Cisco Systems, Inc., Cisco Linksys, LLC, Enterasys Networks, Inc., 3COM Corporation, Inc., Extreme Networks, Inc., Foundry Networks, Inc., Netgear, Inc. and Adtran, Inc. The Company seeks injunctive relief and monetary damages for infringement based upon reasonable royalties as well as treble damages for the defendants continued willful infringement of the Remote Power Patent. The defendants, in their answers to the complaint asserted that they do not infringe any valid claim of the Remote Power Patent, and further asserted that, based on several different theories, the patent claims are invalid or unenforceable. In addition to these defenses, the defendants also asserted counterclaims for, among other things, non-infringement, invalidity, and unenforceability of the Remote Power Patent. In the event that the courts determine that the Remote Power Patent is not valid or enforceable, and/or that the defendants do not infringe, any such determination would have a material adverse effect on the Company.

In August 2005, the Company commenced patent litigation against D-Link Corporation and D-Link Systems, Incorporated (collectively “D-Link”) in the United States District Court for the Eastern District of Texas, Tyler division (Civil Action No. 6:05W291), for infringement of the Company’s Remote Power Patent. The complaint sought, among other things, a judgment that the Company’s Remote Power Patent is enforceable and has been infringed by the defendants. The Company also sought a permanent injunction restraining the defendants from continued infringement, or active inducement of infringement by others, of the Remote Power Patent.

In August 2007, the Company finalized the settlement of its patent infringement litigation against D-Link. Under the terms of the settlement, D-Link entered into a license agreement for the Company’s Remote Power Patent the terms of which include monthly royalty payments of 3.25% of the net sales of D-Link Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards, for the full term of the Company’s Remote Power Patent, which expires in March 2020. The royalty rate is subject to adjustment to a rate consistent with other similarly situated licensees of the Remote Power Patent based on units of shipments of licensed products. In addition, D-Link paid the Company $100,000 upon signing of the Settlement Agreement.
