USPTO PatentsView assignee record - 6 granted patents across 9 technology areas, active 2020–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A47K (SANITARY EQUIPMENT NOT OTHERWISE PROVIDED FOR ; TOILET ACCESSORIES).
The verdict
China holds 6 US patents across 9 technology areas, rank #39,365 of 50,000 tracked assignees.
China Academy OF Aerospace Aerodynamics has been granted 6 US utility patents between 2020 and 2025, placing China Academy OF Aerospace Aerodynamics at rank #39,365 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.0 claims per patent with primary concentration in A47K (SANITARY EQUIPMENT NOT OTHERWISE PROVIDED FOR ; TOILET ACCESSORIES). As a Foreign Corporation, China Academy OF Aerospace Aerodynamics is one of the more focused assignees in the PatentsView dataset. By volume, China sits between Cheminova A/s (6 patents, rank #39,361) and China Railway Tunnel Group Co., Ltd. (6 patents, rank #39,369) - the closest US assignees by grant volume. The composite Innovation Score of 40.9/100 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. Historical data spans 2020 through 2025, with 6 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. China Academy OF Aerospace Aerodynamics's 17.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark China Academy OF Aerospace Aerodynamics against peers pursuing similar technology classes.

How to use this portfolio
China's 6 grants land it in the top 34% 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.
