Portfolio overview

Kyoto University has been granted 588 US utility patents between 2015 and 2025, placing Kyoto University at rank #780 across all assignees tracked by PlainPatent. This portfolio spans 188 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.7 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, Kyoto University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kyoto sits between Baxter Healthcare Sa (590 patents, rank #776) and North Carolina State University (585 patents, rank #784) - the closest US assignees by grant volume. The composite Innovation Score of 58.1/100 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 270 grants, compared with 318 in the 2015–2019 window, a -15% 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. Kyoto University's 10.7 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 Kyoto University against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
