Portfolio overview

Soochow University has been granted 362 US utility patents between 2015 and 2025, placing Soochow University at rank #1,177 across all assignees tracked by PlainPatent. This portfolio spans 170 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.0 claims per patent with primary concentration in B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS). As a Foreign Corporation, Soochow University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Soochow sits between Sigmasense, Llc. (363 patents, rank #1,173) and Shenzhen Shokz Co., Ltd. (361 patents, rank #1,181) - the closest US assignees by grant volume. The composite Innovation Score of 63.9/100 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 300 grants, compared with 62 in the 2015–2019 window, a +384% 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. Soochow University's 8.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Soochow 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.
