Where Imerys's grants concentrate

Imerys Minerals Limited is a focused PatentsView assignee: 27 CPC subclasses with 36.4% of grants classified under C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2017. By volume, Imerys sits between ICE Data, Lp and INDI Molecular, Inc..

Imerys's three-year grant acceleration

Imerys Minerals Limited shows 1 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
