Portfolio overview

OHIO State University has been granted 71 US utility patents between 2015 and 2025, placing OHIO State University at rank #4,904 across all assignees tracked by PlainPatent. This portfolio spans 66 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.3 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a US Corporation, OHIO State University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, OHIO sits between National University Corporation Gunma University (71 patents, rank #4,900) and Proxense, Llc (71 patents, rank #4,908) - the closest US assignees by grant volume. The composite Innovation Score of 53.2/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 15 grants, compared with 56 in the 2015–2019 window, a -73% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. OHIO State University's 16.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 66 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark OHIO State University against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
