Portfolio overview

CCCC Highway Consultants Co. Ltd. has been granted 6 US utility patents between 2019 and 2021, placing CCCC Highway Consultants Co. Ltd. at rank #39,325 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.3 claims per patent with primary concentration in E02D (FOUNDATIONS; EXCAVATIONS; EMBANKMENTS ; UNDERGROUND OR UNDERWATER STRUCTURES). As a Foreign Corporation, CCCC Highway Consultants Co. Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, CCCC sits between Cavium International (6 patents, rank #39,321) and CDT Oxford Limited (6 patents, rank #39,329) - the closest US assignees by grant volume. The composite Innovation Score of 31.3/100 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 5 grants, compared with 1 in the 2015–2019 window, a +400% 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. CCCC Highway Consultants Co. Ltd.'s 22.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CCCC Highway Consultants Co. Ltd. against peers pursuing similar technology classes.
