NVIDIA has compiled a 100 percent success rate at the USPTO in challenges to the claims in the patents asserted against it by Rambus in an International Trade Commission (ITC) action filed in November 2008.

"We are pleased that the USPTO decided to review the patentability of these two additional Rambus patents and continued to agree with NVIDIA's challenge to these eight claims," said David Shannon, NVIDIA executive vice president and general counsel. "The USPTO has now initially rejected all of the patent claims asserted by Rambus against NVIDIA in the ITC."

The ITC litigation involves memory controllers related to graphics processors.
