Portfolio overview

Kyushu University, National University Corporation has been granted 261 US utility patents between 2015 and 2025, placing Kyushu University, National University Corporation at rank #1,586 across all assignees tracked by PlainPatent. This portfolio spans 145 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in C07D (HETEROCYCLIC COMPOUNDS). As a Foreign Corporation, Kyushu University, National University Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kyushu sits between The Lubrizol Corporation (262 patents, rank #1,582) and Thermo Fisher Scientific (bremen) Gmbh (260 patents, rank #1,590) - the closest US assignees by grant volume. The composite Innovation Score of 58.9/100 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 126 grants, compared with 135 in the 2015–2019 window, a -7% 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. Kyushu University, National University Corporation's 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 Kyushu University, National University Corporation against peers pursuing similar technology classes.
