NETWORK-1 ANNOUNCES FINAL LICENSE TERMS AND DISMISSAL OF PATENT LITIGATION WITH D-LINK

D-Link Agrees to License Network-1’s Remote Power Patent for Its Power over Ethernet Products through 2020

NEW YORK, NEW YORK - August 16, 2007 -- Network-1 Security Solutions, Inc. (OTC BB: NSSI) today announced that it has agreed to final licensing terms with  D-Link Corporation and D-Link Systems (“D-Link”) as part of  a definitive Settlement Agreement  of its patent infringement litigation against D-Link in the United States District Court for the Eastern District of Texas, Tyler Division for infringement of  Network-1’s Remote Power Patent (U.S. Patent No. 6,218,930).  

The license terms include the agreement by D-Link to license the Remote Power Patent for its full term which expires in March 2020, and the payment of monthly royalty payments (beginning as of May 26, 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 beginning the second quarter of 2008 to a royalty rate consistent with other similarly situated licensees of the Remote Power Patent that may vary according to units and volumes of licensed products sold. In addition, D-Link has agreed to an upfront payment to Network-1 of $100,000.

The products covered by the settlement include D-Link Power over Ethernet enabled switches, wireless access points, and  network security cameras, among others.  As a result of the definitive Settlement Agreement, all claims and counterclaims in the litigation currently pending in the Eastern District of Texas have been dismissed with prejudice.

"We are extremely pleased at the outcome of this litigation and having D-Link as the first licensee of our Remote Power Patent,” commented Corey M. Horowitz, Chairman and Chief Executive Officer of Network-1.  “This outcome is consistent with Network-1’s goal of making licenses available to the technologies covered by the Remote Power Patent to the Power over Ethernet industry in a manner that promotes the widespread adoption of this important industry standard”.

The Remote Power Patent relates to, among other things, the delivery of power over Ethernet cables in order to remotely power network connected devices including, among others, wireless switches, wireless access points, RFID card readers, VoIP telephones and network cameras. In June 2003, the Institute of Electrical and Electronic Engineers (IEEE) approved the 802.3af Power over Ethernet (“PoE”) standard which has led to the rapid adoption of PoE.  The IEEE is currently working on the 802.3at Power over Ethernet Plus (PoE Plus) Standard which will increase the maximum power delivered to network devices of up to 60 watts from the current 15 watts under 802.3af.
