Where Chemetall's grants concentrate

Chemetall U.S., Inc. is a focused PatentsView assignee: 10 CPC subclasses with 80% of grants classified under C10M (Lubricating Compositions ; USE OF Chemical Substances Either Alone OR AS Lubricating Ingredients IN A Lubricating Composition). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2019. By volume, Chemetall sits between Chekt LLC and Cheorwon Plasma Research Institute.

Chemetall's three-year grant acceleration

Chemetall U.S., Inc. shows 3 grants in 2022–2024 against only 2 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.
