Portfolio overview

University Of Massachusetts has been granted 828 US utility patents between 2015 and 2025, placing University Of Massachusetts at rank #541 across all assignees tracked by PlainPatent. This portfolio spans 187 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.9 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, University Of Massachusetts is one of the broader-portfolio assignees in the PatentsView dataset. By volume, University sits between ABL IP Holding Llc (830 patents, rank #537) and Kaneka Corporation (824 patents, rank #545) - the closest US assignees by grant volume. The composite Innovation Score of 65.2/100 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 488 grants, compared with 340 in the 2015–2019 window, a +44% 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 Massachusetts's 17.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark University Of Massachusetts 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.
