          COURT ALSO DENIES ALL MOTIONS TO DISMISS OR TRANSFER THE CASE

     NEW YORK, FEBRUARY 9, 2006 - Network-1 Security Solutions, Inc. today
announced that, at a case management proceeding on February. 7, 2006, in
Network-1's patent infringement litigation against D-Link Systems Inc. and its
corporate parent D-Link Corporation, Inc. of Taiwan involving United States
Patent No. 6,218,930 in the United States District Court for the Eastern
District of Texas, Tyler Division, Judge Leonard Davis set a Markman hearing on
claim construction for September 19, 2006 and set a trial date of March 7, 2007.

     In addition, at the proceeding, all of the outstanding motions to dismiss
or transfer the case made by the D-Link defendants were denied by Judge Davis
and each is expected to file answers with the Court within 20 days. As a result
of these denials, Network-1's patent infringement case against D-Link Systems
and D-Link Corporation will proceed in the Eastern District of Texas, Tyler
Division in a manner consistent with the timetable and rules established by the
Court.

     "The D-Link defendants have spent the last six months filing numerous
motions in an unsuccessful attempt to avoid dealing with the merits of our
case," commented Corey M. Horowitz, Chairman and CEO of Network-1. "I am pleased
that after these rulings the litigation will proceed on a timely basis."
