MBHB’s Mike Borella and Walter DeGroft Analyze PTAB Section 101 Affirmance Trends in Law360

Law360 covered analysis from MBHB’s Mike Borella and Walter DeGroft of Patent Trial and Appeal Board decisions involving appeals of patent eligibility rejections under Section 101. Their review found that, following the appointment of USPTO Director John Squires, PTAB affirmance rates declined in 2025 compared with prior years. The analysis, originally published on Patent Docs, explores the data behind this trend and discusses what it could mean for patent applicants evaluating whether to appeal Section 101 rejections before the PTAB.
