Rambus Inc. has filed a complaint with the U.S. International Trade Commission (ITC) requesting an investigation into alleged patent violations by graphics chip vendor Nvidia Corp., Rambus said.
Rambus said its complaint with the ITC seeks an exclusion order barring the importation, sale for importation, or sale after importation of products that allegedly infringe nine Rambus patents.
The accused products include Nvidia products that incorporate DDR, DDR2, DDR3, LPDDR, GDDR, GDDR2, and GDDR3 memory controllers, including graphics processors, and media and communications processors, Rambus said.
"We believe this action is necessary given Nvidia's continued willful infringement of our patents," said Tom Lavelle, senior vice president and general counsel at Rambus, in a statement.
The ITC is expected to decide whether to initiate an investigation under this complaint within 30 days, Rambus said.
