the study determined that 73.5% of the challenged claims did not survive review in IPR proceedings that reached a final decision on the merits. The report also shows that, in final decisions from the PTAB, 37.5% of the claims initially challenged were found unpatentable under 35 U.S.C. § 102 (anticipation), while 57.6% of the claims were found unpatentable under 35 U.S.C. § 103 (obviousness). (Some claims were found unpatentable under both grounds.) In a recent study of patent decisions in district court cases, the district courts invalidated claims under Section 102 at a rate of 31.1% and under Section 103 at a rate of 27.8%.
