May 4, 2001- Richmond, VA – The judge presiding over the Rambus/Infineon trial has tossed out the remaining three patent infringement claims against Infineon, and Rambus has promised an appeal.

US District Judge Robert Payne dismissed Rambus’ case against Infineon by granting a motion by Infineon Technologies AG to dismiss the three claims. Earlier this week, Payne tossed out 54 claims Rambus had brought against Infineon.

The claims were part of a suit filed by Rambus over use of its patents in SDRAMs and DDR SDRAMs manufactured and sold by Infineon in the United States. Infineon claimed that Rambus’ top management continuously took part in discussions concerning how the RDRAM patent could be changed to cover the JEDEC industry SDRAM standard. Rambus claims Infineon instead took parts of the RDRAM intellectual property for the JEDEC SDRAM standard.

“We are disappointed with the court’s decision and plan to appeal the ruling,” said Geoff Tate, CEO of Rambus. “If today’s decision is allowed to stand, all companies that innovate risk having their intellectual property rights unjustly expropriated.

“Rambus will continue to fight to protect our intellectual property. It is our right, and indeed our obligation to our shareholders, to take all appropriate measures to protect our patented innovations. Though Rambus is a relatively small company, we will not be cowed by the aggressive tactics of some industry giants who would take our innovations without any compensation.”
