We already reported several times that RAMBUS is investing more in lawyers to sue any companies that might have used part of RAMBUS intellectual properties covered by patents with general and broad claims. The recent target of RAMBUS strategy to be financially healthy is NVidia. According to the company, the GPU designer and manufacturer has been using without rights or appropriate licensing 7 of its patents. Interestingly, instead of going to justice to fight with such patent infringement claims, NVidia decided to ask the U.S. Patent and Trademark Office to review the patentability of RAMBUS' patents. The US PTO rejected 7 of the quoted patents, making those filing history and invalidating them. Tw additional patents are still on review by the PTO and might end to the same conclusion.
