Judge throws out most of Rambus claims

All but three of Rambus' patent claims against Germany's Infineon were dismissed by a US federal judge in Richmond, Virginia late on Monday. The move is a new twist for Rambus' case against the semiconductor manufacturer, in which billions of dollars of royalties are at stake.

All but three of Rambus' patent claims against Germany's Infineon were dismissed by a US federal judge in Richmond, Virginia late on Monday. The move is a new twist for Rambus' case against the semiconductor manufacturer, in which billions of dollars of royalties are at stake.

Judge Robert Payne of the U.S. District Court in Richmond, Virginia said Rambus' case had failed to prove that a large number of Rambus' 104 US patents had been incorporated into Infineon's memory products, following non-disclosure technical briefings by Rambus in the early 90s. The judge also indicated that he would not find Infineon guilty of "wilfully" violating Rambus' patents, according to industry reports. Full story. --Matthew Broersma, ZDNet UK
