Portfolio overview

Imerys Filtration Minerals, Inc. has been granted 8 US utility patents between 2015 and 2019, placing Imerys Filtration Minerals, Inc. at rank #32,074 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.6 claims per patent with primary concentration in C03C (CHEMICAL COMPOSITION OF GLASSES, GLAZES OR VITREOUS ENAMELS; SURFACE TREATMENT OF GLASS; SURFACE TREATMENT OF FIBRES OR FILAMENTS MADE FROM GLASS, MINERALS OR SLAGS; JOINING GLASS TO GLASS OR OTHER MA). As a US Corporation, Imerys Filtration Minerals, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Imerys sits between Idera, Inc. (8 patents, rank #32,070) and Imperative Chemical Partners Inc. (8 patents, rank #32,078) - the closest US assignees by grant volume. The composite Innovation Score of 29.9/100 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 0 grants, compared with 8 in the 2015–2019 window, a -100% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Imerys Filtration Minerals, Inc.'s 17.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Imerys Filtration Minerals, Inc. against peers pursuing similar technology classes.
