In 2010, GPHI announced it had won a significant favorable ruling in its litigation with ATI Technologies and AMD in June 2010, following the patent lawsuit originally filed during the Silicon Graphics, Inc. era. Following the 2008 appeal by ATI over the validity of ('327) and Silicon Graphics Inc's voluntary dismissal of the ('376) patent from the lawsuit, the Federal Circuit upheld the jury verdict on the validity of GPHI's U.S. Patent No. 6,650,327, and furthermore found that AMD had lost its right to challenge patent validity in future proceedings. On January 31, 2011, the District Court entered an order that permits AMD to pursue its invalidity affirmative defense at trial and does not permit SGI to accuse AMD's Radeon R700 series of graphics products of infringement in this case. On April 18, 2011, GPHI and AMD had entered into a confidential Settlement and License Agreement that resolved this litigation matter for an immaterial amount and that provides immunity under all GPHI patents for alleged infringement by AMD products, including components, software and designs. On April 26, 2011, the Court entered an order granting the parties' agreed motion for dismissal and final judgment.
