Rambus’ Case Against Infineon Is Dismissed

A U.S. judge dismissed Rambus Inc.’s patent infringement lawsuit against German chip maker Infineon Technologies.

U.S. District Judge Robert Payne in Richmond, Va., said that the dismissal of the lawsuit was the “only appropriate action” to punish Rambus for destruction of documents relating to its patent litigation strategy. He said Infineon had successfully argued that Rambus destroyed the documents to prevent chip makers from challenging Rambus patents.

Shares of Los Altos, Calif.-based Rambus fell $1.86 to $15.34 in extended trading after falling as low as $14.70 after the ruling. The shares closed at $17.16 on Nasdaq.
