Rambus wins latest round in Nvidia patent dispute

Rambus has overcome the latest hurdle in its patent suit against Nvidia, gaining an exclusion order on imports based on three of its patents.

The International Trade Commission yesterday agreed that Nvidia was infringing three Rambus patents and ordered it to stop certain imports. Full details of the ruling haven’t been released.

The case dates back to November 2008, when Rambus filed its initial complaint. It asked for an exclusion order barring the importation and sale of products which it said infringed nine of its patents. It later dropped five of these from the complaint.

The products included graphics processors, application processors, media and communications processors, and chip sets which incorporated certain memory controllers.

The complaint also named Nvidia customers including Asustek and HP. The ITC has now said it plans to issue a Limited Exclusion Order barring imports of infringing products into the US.

“The ITC’s decision is another demonstration of the value of our continued commitment to innovation,” said Thomas Lavelle, senior vice president and general counsel at Rambus.

“We are extremely pleased with the ITC’s decision to issue a Limited Exclusion Order, signaling the strength of our innovation efforts beyond the Farmwald-Horowitz patents of our founders. The value of our patented inventions has been recognized by our current licensees, and we will continue our efforts to license others.”

Because of a European licensing agreement, Nvidia shouild still be able to fulfil orders. According to Bloomberg, it plans to appeal.
