Where Chemrus's grants concentrate

Chemrus, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 60% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Chemrus sits between Chelak Medical Solutions Inc and Chiayo Electronics Co., Ltd..

Chemrus's three-year grant acceleration

Chemrus, Inc. shows 1 grants in 2022–2024 against only 1 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.
