The institution rate for post-grant challenges in current FY 2020 (Oct. 1, 2019 through June 30, 2020) stands at 56% (478 instituted, 376 denied) compared to 63% in the previous fiscal year. This lower institution rate compared to prior years, and its effect on petition filings, are items that we continue to keep a close eye on. April institutions were 62 institutions to 30 denials (67.4% institution).
Through July FY 2020, 990 IPR petitions, 52 PGR petitions, and 11 CBM petitions have been filed.
