Portfolio overview

National University Corporation Shiga University OF Medical Science has been granted 11 US utility patents between 2016 and 2025, placing National University Corporation Shiga University OF Medical Science at rank #24,835 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, National University Corporation Shiga University OF Medical Science is one of the more focused assignees in the PatentsView dataset. By volume, National sits between National Center FOR Nanoscience AND Technology (11 patents, rank #24,831) and NDM Technologies Limited (11 patents, rank #24,839) - the closest US assignees by grant volume. The composite Innovation Score of 36.3/100 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 8 grants, compared with 3 in the 2015–2019 window, a +167% 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. National University Corporation Shiga University OF Medical Science's 11.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark National University Corporation Shiga University OF Medical Science against peers pursuing similar technology classes.
