Portfolio overview

CASE Western Reserve University has been granted 856 US utility patents between 2015 and 2025, placing CASE Western Reserve University at rank #526 across all assignees tracked by PlainPatent. This portfolio spans 149 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.4 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, CASE Western Reserve University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, CASE sits between Sharkninja Operating Llc (862 patents, rank #522) and Semiconductor Manufacturing International (beijing) Corporation (848 patents, rank #530) - the closest US assignees by grant volume. The composite Innovation Score of 63.4/100 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 505 grants, compared with 351 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. CASE Western Reserve University's 16.4 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 CASE Western Reserve 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.
