Where KH's grants concentrate

KH Neochem Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 81.8% 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 2016 (3 grants) versus a trough of 1 in 2018. By volume, KH sits between Kapman AB and Kitamura Machinery Co., Ltd..

KH's three-year grant acceleration

KH Neochem Co., Ltd. shows 2 grants in 2022–2024 against only 3 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.
