AVOCENT REPORTS COURT OF APPEALS RULING

IN PATENT INFRINGEMENT LAWSUIT

HUNTSVILLE, Ala. — April 3, 2003 — Avocent Corporation (Nasdaq:AVCT) announced today that the United States Court of Appeals for the Federal Circuit issued its ruling in the patent litigation between Apex Inc., a wholly owned subsidiary of Avocent, and Raritan Computer Inc.  The Court of Appeals ruled in favor of Apex by vacating the decision of the District Court for the Southern District of New York.

In yesterday’s ruling, a three-judge panel of the Court of Appeals for the Federal Circuit unanimously found that the District Court, which had previously ruled in favor of Raritan, erred as a matter of law in the construction of the disputed claim limitations of the three patents that Apex alleged Raritan infringed.  The Court of Appeals vacated the District Court’s grant of judgment of non-infringement and remanded the case for further proceedings consistent with the Court of Appeals’ opinion.  The ruling follows Apex’s May 2001 filing of a complaint for patent infringement against Raritan seeking injunctive relief, damages, attorneys’ fees and costs under three Apex patents.

“We are extremely pleased with the decision of the Court of Appeals,” stated Samuel F. Saracino, senior vice president of legal and corporate affairs of Avocent Corporation.  “We believe that our patents and intellectual property are valuable assets, and we will continue to vigorously protect our rights in those patents.”
