Nov. 28, 2001 – San Jose, CA – The US District Court for the Northern District of California dismissed all but two of the more than 400 patent claims brought by Rambus against Hynix Semiconductor Inc., finding that the Korean company’s SDR and DDR DRAM devices do not infringe Rambus’ patents.

The ruling was based on definitions issued by a court in a similar lawsuit between Rambus and Infineon.

Hynix’s allegations that Rambus committed fraud and violated the antitrust laws by its illegal behavior in the industry standards-setting organization, JEDEC, remain for trial.

Rambus has already been found guilty of fraud in connection with its participation in JEDEC. The court temporarily stayed further proceedings in the Hynix case pending consideration of certain procedural matters.

“We are extremely pleased with this ruling,” said Farhad Tabrizi, Hynix’s vice president of worldwide memory marketing. “Hynix helped pioneer the DDR architecture, and this ruling clearly vindicates our position and prevents Rambus from using the courts to eliminate legitimate competition. It is also a victory for the concept of open standards, something that has helped accelerate and make more affordable the implementation of the new electronic technologies that are transforming the modern world.”
