Rambus Inc., which designs memory chips, said Friday that an administrative judge for the U.S International Trade Commission has ruled that graphics chip maker Nvidia Corp. has violated three of its patents.

The initial determination of patent infringement may be reviewed. The judge also ruled that Nvidia did not violate two other patents.

Rambus first filed a patent complaint with the ITC in November 2008, requesting an investigation into Nvidia products. Rambus asked the ITC to stop the importing and sale of Nvidia products that it said infringed on nine of its patents. Four of the patents were later withdrawn from the investigation.

The products in the complaint are products that incorporate certain Nvidia memory controllers, including graphics processors and media and communications processors.

Rambus shares rose 72 cents, or 3 percent, to close at $24.74. They earlier set a new year high of $26.

Nvidia shares lost 59 cents, or 3.5 percent, to end trading at $16.46.
