Portfolio overview

Kochi Prefectural Public University Corporation has been granted 9 US utility patents between 2018 and 2025, placing Kochi Prefectural Public University Corporation at rank #29,213 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.1 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Kochi Prefectural Public University Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Kochi sits between Kinshofer Gmbh (9 patents, rank #29,209) and Koska Family Limited (9 patents, rank #29,217) - the closest US assignees by grant volume. The composite Innovation Score of 24.7/100 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 7 grants, compared with 2 in the 2015–2019 window, a +250% 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. Kochi Prefectural Public University Corporation's 7.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kochi Prefectural Public University Corporation against peers pursuing similar technology classes.
