Portfolio overview

University Of Hong Kong has been granted 186 US utility patents between 2015 and 2025, placing University Of Hong Kong at rank #2,124 across all assignees tracked by PlainPatent. This portfolio spans 113 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.9 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, University Of Hong Kong is one of the broader-portfolio assignees in the PatentsView dataset. By volume, University sits between International Paper Company (186 patents, rank #2,120) and Cooler Master Co., Ltd. (185 patents, rank #2,128) - the closest US assignees by grant volume. The composite Innovation Score of 57.4/100 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 118 grants, compared with 68 in the 2015–2019 window, a +74% 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. University Of Hong Kong's 15.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark University Of Hong Kong against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
