Short Summary
TCL Industries Holdings Co., Ltd. successfully challenged ATI Technologies ULC's patent claims under 35 U.S.C. § 103, focusing on obviousness over multiple prior art combinations. The PTAB found a reasonable likelihood of success for the petitioner on specific grounds, leading to an institution decision.
Detailed Summary
TCL Industries Holdings Co., Ltd. (Petitioner) challenged claims 1-11 of ATI Technologies ULC's patent under 35 U.S.C. § 103, arguing that they were obvious in light of several prior art references. The grounds involved combining Lindholm ’6853 with other Lindholm references, and similarly combining Amanatides/Kohn and Selzer/Fiske to achieve specific technical goals like dynamic load balancing or unified shader functionality. The Board construed the term 'unified shader' as a shader configured to perform both vertex and pixel operations. Given the detailed arguments regarding motivation to combine prior art teachings, the PTAB issued an institution decision, finding a reasonable likelihood of success for TCL Industries Holdings Co., Ltd.
