Portfolio overview
SEOUL NATIONAL UNIVERSITY HOSPITAL has been granted 58 US utility patents between 2015 and 2025, placing SEOUL NATIONAL UNIVERSITY HOSPITAL at rank #5,880 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, SEOUL NATIONAL UNIVERSITY HOSPITAL is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 49.3/100 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 52 grants, compared with 6 in the 2015–2019 window — a +767% 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. SEOUL NATIONAL UNIVERSITY HOSPITAL's 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SEOUL NATIONAL UNIVERSITY HOSPITAL against peers pursuing similar technology classes.
