Portfolio overview

UNIVERSITY OF TSUKUBA has been granted 127 US utility patents between 2015 and 2025, placing UNIVERSITY OF TSUKUBA at rank #2,996 across all assignees tracked by PlainPatent. This portfolio spans 103 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.6 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, UNIVERSITY OF TSUKUBA is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 54.4/100 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 71 grants, compared with 56 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. UNIVERSITY OF TSUKUBA's 10.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 TSUKUBA against peers pursuing similar technology classes.
