Portfolio overview
Sogang University Research Foundation has been granted 126 US utility patents between 2015 and 2025, placing Sogang University Research Foundation at rank #3,026 across all assignees tracked by PlainPatent. This portfolio spans 95 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Sogang University Research Foundation is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 53.4/100 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 60 grants, compared with 66 in the 2015–2019 window — a -9% 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. Sogang University Research Foundation's 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 95 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sogang University Research Foundation against peers pursuing similar technology classes.
