Portfolio overview

The Hong Kong Polytechnic University has been granted 149 US utility patents between 2015 and 2025, placing The Hong Kong Polytechnic University at rank #2,617 across all assignees tracked by PlainPatent. This portfolio spans 129 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, The Hong Kong Polytechnic University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, The sits between Nippon Seiki Co., Ltd. (149 patents, rank #2,613) and Ablynx N.v. (148 patents, rank #2,621) - the closest US assignees by grant volume. The composite Innovation Score of 56.2/100 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 67 grants, compared with 82 in the 2015–2019 window, a -18% 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. The Hong Kong Polytechnic University's 15.0 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 The Hong Kong Polytechnic University against peers pursuing similar technology classes.
