Key Finding: This chart presents the percentage of claims found unpatentable under Sections 101, 102, 103, and 112 for all CBM petitions which either reached a final written decision, or were denied institution for substantive reasons rather than procedural reasons (e.g., time-barred). The analysis includes decisions not to institute through 2014, and final decisions through 2015, due to the temporal relationship between these types of decisions. That one year differential avoids an improper skewing toward the outcomes of decisions not to institute. The rate of unpatentability of claims challenged under Section 101 is higher than the corresponding rate under Sections 102, 103, and 112. Note that some claims were found unpatentable on multiple bases. Claims cancelled by patent owner and cases denied institution for failing to claim a qualifying business method are excluded from the analysis.
