Portfolio overview

The Euclid Chemical Company has been granted 8 US utility patents between 2016 and 2024, placing The Euclid Chemical Company at rank #33,626 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE). As a US Corporation, The Euclid Chemical Company is one of the more focused assignees in the PatentsView dataset. By volume, The sits between The Berea Hardwoods Co., Inc. (8 patents, rank #33,622) and The National Telephone Supply Company (8 patents, rank #33,630) - the closest US assignees by grant volume. The composite Innovation Score of 30.1/100 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 4 grants, compared with 4 in the 2015–2019 window, a +0% 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. The Euclid Chemical Company's 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark The Euclid Chemical Company against peers pursuing similar technology classes.
