Portfolio overview

Universite DE Nantes has been granted 118 US utility patents between 2015 and 2025, placing Universite DE Nantes at rank #3,189 across all assignees tracked by PlainPatent. This portfolio spans 86 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, Universite DE Nantes is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Universite sits between Samsung LIFE Public Welfare Foundation (118 patents, rank #3,185) and Daido Metal Company Ltd. (117 patents, rank #3,193) - the closest US assignees by grant volume. The composite Innovation Score of 52.4/100 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 66 grants, compared with 52 in the 2015–2019 window, a +27% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign 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. Universite DE Nantes's 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 86 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Universite DE Nantes against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
