ParkerVision appeals from three final written decisions of the PTAB in related inter partes review proceedings, in which the Board held certain claims of U.S. Patent No. 6,091,940 (generally relating to telecommunications devices, such as cellular phones, in which low frequency electromagnetic signals are “up-converted” to higher-frequency signals by various means) unpatentable as obvious. Qualcomm cross-appeals from the Board’s determination that Qualcomm failed to prove by a preponderance of the evidence that certain other claims are unpatentable. Separately analyzing the apparatus and method claims, the CAFC affirms.
