Xilinx to Appeal Judge's Ruling in Patent Case

SAN JOSE, Calif.
May 10, 2001

Xilinx, Inc. (NASDAQ: XLNX) today said that it plans to appeal a judge's decision to overturn a verdict reached by a jury last year that supported patent infringement claims by Xilinx against Altera Corp.

"After seven years of litigation and six weeks of trial, Xilinx believes that the jury reached the correct verdict, and the judge made the wrong decision," said Tom Lavelle, general counsel for Xilinx. "We plan to appeal the judge's decision, and Xilinx will continue to use all legal means to protect its intellectual property rights."

The ruling to overturn the jury's verdict was made by Judge James Ware, who presided over the patent infringement trial last October and November in Federal District Court in San Jose.

In a separate legal action on June 25, the International Trade Commission will hear Xilinx claims against Altera alleging infringement of three additional Xilinx patents. Xilinx is requesting that the ITC bar any infringing Altera products in this case from entering the United States. The Altera products covered by the ITC filing include all of the Flex, Apex, and Acex families.
