Nov. 27, 2001 – Los Altos, CA – The US District Court for the Eastern District of Virginia today issued its final ruling in Rambus vs. Infineon, entering an injunction against Rambus, keeping the company from enforcing some of its patents against some Infineon products.

The order, although based on Rambus’ participation in JEDEC from 1992 through 1995, includes Infineon products designed under JEDEC’s DDR SDRAM standard, adopted in June 2000. As to DDR SDRAM, the order reaches some, but not all, Rambus patents.

“Today’s order was largely as expected, and will be swiftly appealed,” said John Danforth, senior vice president and general counsel of Rambus Inc. “With all due respect to the Virginia District Court, today’s order builds upon and adds to a series of reversible errors previously made by the same court. These include clear errors of law and fact that are the subject of a pending Rambus appeal for which Rambus has already filed its opening brief. The breadth of today’s order amplifies these earlier mistakes and adds further reversible errors that Rambus will separately contest. We look forward to successfully resolving these issues in the Court of Appeal for the Federal Circuit.”
