How Ohio's grant cadence moved

Between 2020–2024, Ohio State University received 13 grants versus 56 in 2015–2019 (-77% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2015 at 19 grants and bottomed in 2024 at 1. Lead class A61P accounts for 45.1% of the portfolio across 66 subclasses. Volume neighbours: National University Corporation Gunma University (#4,900) and Proxense, LLC (#4,908).

Ohio's three-year grant acceleration

Ohio State University shows 6 grants in 2022–2024 against only 11 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
