Portfolio overview
OSAKA CITY UNIVERSITY has been granted 33 US utility patents between 2015 and 2023, placing OSAKA CITY UNIVERSITY at rank #9,576 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.6 claims per patent with primary concentration in G01R (MEASURING ELECTRIC VARIABLES; MEASURING MAGNETIC VARIABLES). As a Foreign Corporation, OSAKA CITY UNIVERSITY is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.7/100 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 11 grants, compared with 22 in the 2015–2019 window — a -50% 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. OSAKA CITY UNIVERSITY's 11.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 41 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark OSAKA CITY UNIVERSITY against peers pursuing similar technology classes.
