Infineon Wins Ruling in Rambus Dispute

German chipmaker Infineon Technologies claimed another success in its long-running legal dispute with memory-chip designer Rambus Inc., after a judge barred Rambus from asserting certain of its patents against some of Infineon’s memory chips.

Specifically, the injunction issued by Judge Robert Payne of Federal District Court for the Eastern District of Virginia will prohibit Los Altos, Calif.-based Rambus from asserting its patents against Infineon for SDRAM and DDR SDRAM chips it makes according to open industry standards, Infineon said.

Rambus officials could not immediately be reached for comment.

Rambus shares fell 24 cents to $10.09 on Nasdaq, while Infineon rose $1.25 to close at $21.20 on the NYSE, before Infineon issued its statement.
