Portfolio overview
Chubu University Educational Foundation has been granted 13 US utility patents between 2015 and 2025, placing Chubu University Educational Foundation at rank #20,903 across all assignees tracked by PlainPatent. This portfolio spans 32 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in C07K (PEPTIDES). As a Foreign Corporation, Chubu University Educational Foundation is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 55.4/100 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 8 grants, compared with 5 in the 2015–2019 window, a +60% 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. Chubu University Educational Foundation's 10.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 32 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chubu University Educational Foundation against peers pursuing similar technology classes.
