USPTO PatentsView assignee record - 9 granted patents across 12 technology areas, active 2023–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A61B (DIAGNOSIS; SURGERY; IDENTIFICATION).
The verdict
Jianghan holds 9 US patents across 12 technology areas, rank #29,132 of 50,000 tracked assignees.
Jianghan University has been granted 9 US utility patents between 2023 and 2025, placing Jianghan University at rank #29,132 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.6 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, Jianghan University is one of the more focused assignees in the PatentsView dataset. By volume, Jianghan sits between Jcdecaux Sa (9 patents, rank #29,128) and Johnson Controls AIR Conditioning AND Refrigeration (wuxi) Co., Ltd. (9 patents, rank #29,136) - the closest US assignees by grant volume. The composite Innovation Score of 44.7/100 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. Historical data spans 2023 through 2025, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Jianghan University's 7.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Jianghan University against peers pursuing similar technology classes.

How to use this portfolio
Jianghan's 9 grants land it in the top 25% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
