USPTO PatentsView assignee record - 10 granted patents across 9 technology areas, active 2015–2022. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B65D (CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR F).
The verdict
Shanghai holds 10 US patents across 9 technology areas, rank #27,315 of 50,000 tracked assignees.
Shanghai Air-paq Composite Material Co., Ltd. has been granted 10 US utility patents between 2015 and 2022, placing Shanghai Air-paq Composite Material Co., Ltd. at rank #27,315 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.4 claims per patent with primary concentration in B65D (CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR F). As a Foreign Corporation, Shanghai Air-paq Composite Material Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shanghai sits between Serralux Inc. (10 patents, rank #27,311) and Shanghai Nuclear Engineering Research & Design Institute Co., Ltd. (10 patents, rank #27,319) - the closest US assignees by grant volume. The composite Innovation Score of 25.6/100 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 5 grants, compared with 5 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Shanghai Air-paq Composite Material Co., Ltd.'s 9.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Air-paq Composite Material Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Shanghai's 10 grants land it in the top 82% 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.
