(“Fox”) on remand and cancelled the challenged claims of SRAM LLC’s (“SRAM”) U.S. Patent No. 9,182,027 (the ’027 Patent), directed towards anchoring a bicycle’s drive chain and preventing its disengagement from the chainring. Fox Factory, 944 F.3d at 1378. The Federal Circuit remanded on the issue of “reevaluat[ing] the import of the evidence of secondary considerations with the burden of proving nexus placed on the correct party.” (Decision at 8). On remand the PTAB made clear it was considering the evidence “in light of the Federal Circuit’s Decision.” (Decision at 10). Noting SRAM did not present any additional arguments, the PTAB assigned the existing evidence “little or no weight” in finding SRAM failed to establish a nexus between that evidence and the claimed invention. (Decision at 11).
