Portfolio overview
Osaka University has been granted 702 US utility patents between 2015 and 2025, placing Osaka University at rank #635 across all assignees tracked by PlainPatent. This portfolio spans 199 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, Osaka University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Osaka sits between DOW Agrosciences Llc (704 patents, rank #631) and Rutgers, The State University Of New Jersey (698 patents, rank #639) - the closest US assignees by grant volume. The composite Innovation Score of 61.6/100 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 434 grants, compared with 268 in the 2015–2019 window, a +62% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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 University's 11.1 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 Osaka University against peers pursuing similar technology classes.
