Portfolio overview
NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY has been granted 262 US utility patents between 2015 and 2025, placing NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY at rank #1,581 across all assignees tracked by PlainPatent. This portfolio spans 140 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 58.7/100 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 122 grants, compared with 140 in the 2015–2019 window — a -13% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY's 10.4 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 NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY against peers pursuing similar technology classes.
