Portfolio overview

Jiangsu Normal University has been granted 7 US utility patents between 2019 and 2025, placing Jiangsu Normal University at rank #36,040 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.1 claims per patent with primary concentration in C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE). As a Foreign Corporation, Jiangsu Normal University is one of the more focused assignees in the PatentsView dataset. By volume, Jiangsu sits between Jiangmen Jinlong High Technology Industrial Co., Ltd. (7 patents, rank #36,036) and Jitsubo Co., Ltd. (7 patents, rank #36,044) - the closest US assignees by grant volume. The composite Innovation Score of 30.6/100 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 6 grants, compared with 1 in the 2015–2019 window, a +500% 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. Jiangsu Normal University's 7.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Jiangsu Normal University against peers pursuing similar technology classes.

How to use this portfolio

Jiangsu's 7 grants land it in the top 65% 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 #36,040 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in C04B - see who else leads that technology area. C04B 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.
