Portfolio overview

SUN Yat-sen University has been granted 94 US utility patents between 2015 and 2025, placing SUN Yat-sen University at rank #3,858 across all assignees tracked by PlainPatent. This portfolio spans 78 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, SUN Yat-sen University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, SUN sits between National University Corporation Tokai National Higher Education AND Research System (94 patents, rank #3,854) and Sportsmedia Technology Corporation (94 patents, rank #3,862) - the closest US assignees by grant volume. The composite Innovation Score of 56.5/100 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 80 grants, compared with 14 in the 2015–2019 window, a +471% 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. SUN Yat-sen University's 10.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 78 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SUN Yat-sen University against peers pursuing similar technology classes.

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.
