Infineon loses motion in Rambus case

The Federal Circuit Court of Appeals on Friday denied a motion filed by Infineon that, if granted, would have allowed a panel of judges to examine a recent ruling that essentially overturned trial-level verdicts in favor of the German memory maker in its lawsuit against Rambus, which designs high-speed memory.

In the lawsuit, Rambus accused Infineon of infringing its patents while Infineon accused Rambus of fraud. A jury found that Rambus committed fraud while the trial court judge limited Rambus' patent claims. In January, the U.S. Court of Appeals for the Federal District tossed out the jury verdict and ordered a new trial on the patent issues in the case. No date has been set for the new trial. Infineon can appeal this recent ruling to the U.S. Supreme Court.
