TechPowerUp reports AMD won back ownership of three graphic patents in an appeal case against LG. In a previous ruling, the Patent Trial and Appeal Board (PTAB) threw out three patents dealing with technology related to Unified Shaders. Now a U.S. Court of Appeals for the Federal Circuit overruled this, stating AMD subsidiary ATI conceived their inventions before the supposed prior art:
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.
