AMD received again possession of three graphics patents that had earlier been struck down on a criticism 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 noticed that AMD subsidiary ATI Technologies ULC (now reorganized as RTG), has a declare to U.S. patents numbered 7,742,053, 6,897,871, and seven,327,369. The three patents cope with crucial know-how associated to Unified Shaders.
The PTAB had earlier dismissed ATI’s possession 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 choice dominated that ATI had “had conceived of their inventions before the prior art.” Put merely, the courtroom was happy that the applied sciences protected by these patents had been invented by ATI earlier than the “prior art,” and weren’t “obvious next steps” to it.
