Portfolio overview

National University Corporation, Iwate University has been granted 34 US utility patents between 2015 and 2025, placing National University Corporation, Iwate University at rank #9,328 across all assignees tracked by PlainPatent. This portfolio spans 44 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in C08G (MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS). As a Foreign Corporation, National University Corporation, Iwate University is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Medtronic Ventor Technologies Ltd. (34 patents, rank #9,324) and Nidec Seimitsu Corporation (34 patents, rank #9,332) - the closest US assignees by grant volume. The composite Innovation Score of 48.7/100 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 20 grants, compared with 14 in the 2015–2019 window, a +43% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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, Iwate University's 10.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 44 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National University Corporation, Iwate University against peers pursuing similar technology classes.
