National University Corporation Nagoya University

National University Corporation Nagoya University has been granted 210 US utility patents between 2015 and 2025, placing National University Corporation Nagoya University at rank #1,913 across all assignees tracked by PlainPatent. This portfolio spans 129 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, National University Corporation Nagoya University is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 53.3/100 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 81 grants, compared with 129 in the 2015–2019 window — a -37% 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. National University Corporation Nagoya University's 11.7 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 National University Corporation Nagoya University against peers pursuing similar technology classes.
