Portfolio overview

Clark Equipment Company has been granted 145 US utility patents between 2015 and 2023, placing Clark Equipment Company at rank #2,674 across all assignees tracked by PlainPatent. This portfolio spans 70 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 claims per patent with primary concentration in E02F (DREDGING; SOIL-SHIFTING). As a US Corporation, Clark Equipment Company is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Clark sits between Sangamo Therapeutics, Inc. (146 patents, rank #2,670) and JSP Corporation (145 patents, rank #2,678) - the closest US assignees by grant volume. The composite Innovation Score of 55.0/100 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 81 grants, compared with 64 in the 2015–2019 window, a +27% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The US 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. Clark Equipment Company's 13.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 70 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Clark Equipment Company 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.
