AMD Wins Back Three Graphics Patents from LG
AMD won back ownership of three graphics patents that had earlier been struck down on a complaint by LG Electronics. A U.S. Court of Appeals for the Federal Circuit overruled a ruling of the Patent Trial and Appeal Board (PTAB) which observed that AMD subsidiary ATI Technologies ULC (now reorganized as RTG), has a claim to U.S. patents numbered 7,742,053, 6,897,871, and 7,327,369. The three patents deal with critical technology related to Unified Shaders.
The PTAB had earlier dismissed ATI's ownership of the patents on grounds that the IP claimed was "too obvious in light of prior art." A bench of three Judges in a unanimous decision ruled that ATI had "had conceived of their inventions before the prior art." Put simply, the court was satisfied that the technologies protected by these patents were invented by ATI before the "prior art," and were not "obvious next steps" to it.
