Portfolio overview

Citic Dicastal Co., Ltd. has been granted 538 US utility patents between 2016 and 2025, placing Citic Dicastal Co., Ltd. at rank #847 across all assignees tracked by PlainPatent. This portfolio spans 112 distinct Cooperative Patent Classification (CPC) subclasses, averaging 3.6 claims per patent with primary concentration in B60B (VEHICLE WHEELS ; CASTORS; AXLES FOR WHEELS OR CASTORS; INCREASING WHEEL ADHESION). As a Foreign Corporation, Citic Dicastal Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Citic sits between Funai Electric Co., Ltd. (541 patents, rank #843) and Technion Research & Development Foundation Limited (537 patents, rank #851) - the closest US assignees by grant volume. The composite Innovation Score of 53.3/100 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 397 grants, compared with 141 in the 2015–2019 window, a +182% 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. Citic Dicastal Co., Ltd.'s 3.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Citic Dicastal Co., Ltd. against peers pursuing similar technology classes.

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.
