Where Imerys's grants concentrate

Imerys Graphite & Carbon Switzerland, SA is a focused PatentsView assignee: 24 CPC subclasses with 73.7% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2020. By volume, Imerys sits between I.D.E. Technologies Ltd and Institute OF Acoustics, Chinese Academy OF Sciences.

Imerys's three-year grant acceleration

Imerys Graphite & Carbon Switzerland, SA shows 3 grants in 2022–2024 against only 5 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.
