Portfolio overview

Jiangsu Provincial Academy Of Environmental Science has been granted 5 US utility patents between 2017 and 2022, placing Jiangsu Provincial Academy Of Environmental Science at rank #48,007 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.2 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Jiangsu Provincial Academy Of Environmental Science is one of the more focused assignees in the PatentsView dataset. By volume, Jiangsu sits between Jessem Products Limited (5 patents, rank #48,003) and Jiangyin Sinbon Electronics Co., Ltd. (5 patents, rank #48,011) - the closest US assignees by grant volume. The composite Innovation Score of 27.2/100 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 1 grants, compared with 4 in the 2015–2019 window, a -75% 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. Jiangsu Provincial Academy Of Environmental Science's 5.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Jiangsu Provincial Academy Of Environmental Science 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.
