Portfolio overview
TOKYO WOMEN'S MEDICAL UNIVERSITY has been granted 33 US utility patents between 2015 and 2023, placing TOKYO WOMEN'S MEDICAL UNIVERSITY at rank #9,642 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in C12N (MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA). As a Foreign Corporation, TOKYO WOMEN'S MEDICAL UNIVERSITY is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.4/100 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 9 grants, compared with 24 in the 2015–2019 window, a -62% 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. TOKYO WOMEN'S MEDICAL UNIVERSITY's 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TOKYO WOMEN'S MEDICAL UNIVERSITY against peers pursuing similar technology classes.
