Enterasys Reaffirms Patent Litigation Initiatives

Market Wire, June, 2008

Enterasys Networks Inc., the Secure Networks Company(TM), today reaffirmed its commitment to a series of intellectual property portfolio initiatives that began in June of 2005. Enterasys currently has approximately 500 patents issued worldwide and continues to aggressively protect its intellectual property rights.

In April 2007, Extreme Networks commenced legal proceedings in the U.S. District Court for the Western District of Wisconsin against Enterasys Networks, alleging infringement of three Extreme patents. On Friday, 30 May 2008, following more than a year of litigation and a nearly two-week trial, Extreme received a jury award in the amount of approximately $200,000. The Wisconsin court did not find any copying or willful infringement by Enterasys.

A final judgment in this matter has not been issued by the Wisconsin court. Enterasys respectfully disagrees with the Wisconsin jury's decision and will continue to pursue all avenues of recourse, including post-trial motions and appeals, to set this verdict aside.

"Enterasys initiated a patent litigation process knowing there could be minor setbacks," said Mike Fabiaschi, Enterasys President and CEO. "We have undertaken a larger strategic process to aggressively defend our intellectual property rights. Our resolve is stronger than ever and in the end we are confident in the strength of our industry innovations."

The Wisconsin trial results are unrelated to the separate, ongoing patent infringement action brought by Enterasys against Extreme in the U.S. District Court for the District of Massachusetts. The specific Enterasys patents involved in the current Massachusetts proceedings were not involved in the Wisconsin trial. Enterasys continues to vigorously pursue the patent infringement claims against Extreme in the Massachusetts case.
