Key Finding: This chart presents, per year, the percentage of claims that were found unpatentable or cancelled out of those challenged by the petitioner in CBM proceedings that reached final written decisions or were denied institution on substantive grounds. These statistics do not account for overall redundancies in patents challenged, as it examines each year’s challenges independently from each other year. The listed periods correspond to the year of the final written decisions. The analyzed decisions not to institute are from one year earlier. As can be seen, the CBM rate has fluctuated within a range, without the discernable trend associated with IPRs.
