The verdict
China holds 26 US patents across 33 technology areas, rank #11,590 of 50,000 tracked assignees.
China International Marine Containers (group) Co., Ltd. has been granted 26 US utility patents between 2016 and 2025, placing China International Marine Containers (group) Co., Ltd. at rank #11,590 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.1 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, China International Marine Containers (group) Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, China sits between Caamtech, Inc. (26 patents, rank #11,586) and Captioncall, Llc (26 patents, rank #11,594) - 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. Between 2020 and 2025 the company received 15 grants, compared with 11 in the 2015–2019 window, a +36% 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. China International Marine Containers (group) Co., Ltd.'s 16.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark China International Marine Containers (group) Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
China's 26 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.
