Where Kumiai's grants concentrate

Kumiai Chemical Industry Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 50% of grants classified under A01N (Preservation OF Bodies OF Humans OR Animals OR Plants OR Parts Thereof ; Biocides, e.g. AS Disinfectants, AS Pesticides OR AS Herbicides ; Pest Repellants OR ATTRACTANTS; Plant Growth Regulators). Peak complete grant year is 2020 (7 grants) versus a trough of 2 in 2015. By volume, Kumiai sits between John Zink Company, LLC and M&R Printing Equipment, Inc..

Kumiai's three-year grant acceleration

Kumiai Chemical Industry Co., Ltd. shows 13 grants in 2022–2024 against only 15 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.
