Where CQV's grants concentrate

CQV Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 78.6% of grants classified under C09C (Treatment OF Inorganic Materials, Other Than Fibrous Fillers, TO Enhance Their Pigmenting OR Filling Properties ; Preparation OF Carbon Black ; ; Preparation OF Inorganic Materials Which ARE NO Sing). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2015. By volume, CQV sits between Continuse Biometrics Ltd. and Crux Biomedical, Inc..

CQV's three-year grant acceleration

CQV Co., Ltd. shows 2 grants in 2022–2024 against only 7 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.
