How Many Petitions for Inter Partes Review Have Less Than All Challenged Claims Granted?

With the recent grant of certiori in SAS Institute Inc. v. Lee, 16-969, the Supreme Court will answer the question:

"Does 35 U.S.C. § 318(a), which provides that the Patent Trial and Appeal Board in an inter partes review 'shall issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner,' require that Board to issue a final written decision as to every claim challenged by the petitioner, or does it allow that Board to issue a final written decision with respect to the patentability of only some of the patent claims challenged by the petitioner, as the Federal Circuit held?"

With Docket Navigator's Motion Success charts, you can create statistics in real-time, 24/7 that show the number of petitions for IPR that had all challenged claims granted, all challenged claims denied, and some claims granted or denied. In the following Motion Sucess chart, the red portions of the chart are petitions that had all challenged claims denied IPR, the green portion had all claims granted, and the gray "partial" portions had some claims granted, and some claims denied IPR:

Success Rates of PTAB Institutions of IPR

As a percentage of total decisions, partial institutions have decreased each year since the AIA was enacted. Denials of all challenged claims (the red portions of the chart) are at an all-time high as a percentage of total institution decisions for each year.
