Today, the U.S. International Trade Commission agreed to review parts of a recent decision by an administrative law judge relating to the '734 and '349 patents. The decision was that NVIDIA had infringed three graphics-related patents belonging to Samsung. It also let stand another part of that decision relating to the '385 patent.

This means that both sides will submit more detail to enable the ITC to make a final determination in late April.

"We are disappointed any part of this decision will stand. We welcome this opportunity to provide further information to the Commission and remain firm in our beliefs that we did not infringe the Samsung patents and that they are invalid," Nvidia said.

The U.S. Patent Trial and Appeals Board has already instituted reviews of two of the three patents, with the third patent expiring in October of this year.
