Portfolio overview

University Of Iowa Research Foundation has been granted 285 US utility patents between 2015 and 2025, placing University Of Iowa Research Foundation at rank #1,459 across all assignees tracked by PlainPatent. This portfolio spans 94 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.5 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, University Of Iowa Research Foundation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, University sits between Jiaxing Super Lighting Electric Appliance Co., Ltd (286 patents, rank #1,455) and Sivantos Pte. Ltd. (284 patents, rank #1,463) - the closest US assignees by grant volume. The composite Innovation Score of 61.7/100 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 159 grants, compared with 126 in the 2015–2019 window, a +26% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. University Of Iowa Research Foundation's 16.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 94 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark University Of Iowa Research Foundation 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.
