Portfolio overview

Jiangsu University has been granted 331 US utility patents between 2015 and 2025, placing Jiangsu University at rank #1,277 across all assignees tracked by PlainPatent. This portfolio spans 195 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.7 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Government, Jiangsu University is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Jiangsu sits between Soitec (332 patents, rank #1,273) and Rheem Manufacturing Company (330 patents, rank #1,281) - the closest US assignees by grant volume. The composite Innovation Score of 65.2/100 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 295 grants, compared with 36 in the 2015–2019 window, a +719% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Government 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. Jiangsu University's 8.7 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 Jiangsu University against peers pursuing similar technology classes.

How to use this portfolio

Jiangsu's 331 grants land it in the top 1% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Jiangsu ranks #1,277 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G01N - see who else leads that technology area. G01N leaders
  • 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.
