Portfolio overview

Saint Louis University has been granted 91 US utility patents between 2015 and 2025, placing Saint Louis University at rank #3,985 across all assignees tracked by PlainPatent. This portfolio spans 48 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, Saint Louis University is one of the more focused assignees in the PatentsView dataset. By volume, Saint sits between Société BIC (91 patents, rank #3,981) and Transdermal Biotechnology, Inc. (91 patents, rank #3,989) - the closest US assignees by grant volume. The composite Innovation Score of 53.7/100 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 48 grants, compared with 43 in the 2015–2019 window, a +12% 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. Saint Louis University's 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 48 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Saint Louis 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.
