Portfolio overview

Imerys Minerals Limited has been granted 11 US utility patents between 2015 and 2022, placing Imerys Minerals Limited at rank #24,507 across all assignees tracked by PlainPatent. This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.1 claims per patent with primary concentration in C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). As a Foreign Corporation, Imerys Minerals Limited is one of the more focused assignees in the PatentsView dataset. By volume, Imerys sits between ICE Data, Lp (11 patents, rank #24,503) and INDI Molecular, Inc. (11 patents, rank #24,511) - the closest US assignees by grant volume. The composite Innovation Score of 45.7/100 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 1 grants, compared with 10 in the 2015–2019 window, a -90% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Imerys Minerals Limited's 20.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 27 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Imerys Minerals Limited 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.
