U.S. Patent Office Rejects All 17 Claims in Three Rambus Patents Asserted Against NVIDIA in International Trade Commission Action

NVIDIA (NASDAQ: NVDA) today announced that the assigned patent examiner at the U.S. Patent and Trademark Office (USPTO) has rejected all 17 claims in three Rambus patents that the company had asserted against NVIDIA in the International Trade Commission (ITC).

The action, known as filing an action closing prosecution, follows preliminary rejection of the claims earlier this year by the USPTO.

"This continues our string of victories against Rambus patents in the USPTO," said David Shannon, NVIDIA executive vice president and general counsel. "We believe these patents are invalid and are confident that a similar decision will be made on the patents that continue to be examined."

There are still eight claims in two other patents involved in the case, which the USPTO has yet to finally determine but which it had preliminarily rejected.

The ITC litigation involves memory controllers related to graphics processors.

NVIDIA (NASDAQ: NVDA) awakened the world to the power of computer graphics when it invented the graphics processing unit (GPU) in 1999. Since then, it has consistently set new standards in visual computing with breathtaking, interactive graphics. Expertise in programmable GPUs has led to breakthroughs in parallel processing which make supercomputing inexpensive and widely accessible. Fortune magazine has ranked NVIDIA #1 in innovation in the semiconductor industry for two years in a row. For more information, see www.nvidia.com
