Apple Inc. received a mixed ruling in the patent-infringement case brought by closely held S3 Graphics Co. over a type of chip used to play video games on mobile devices.

Apple violates two S3 patents and was found to not have infringed two others, U.S. International Trade Commission Judge James Gildea said in a notice today on the Washington-based agency’s website. The findings are subject to review by the six-member commission, which can block imports of products that infringe U.S. patents.
