Where Korea's grants concentrate

Korea Western Power Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 60% of grants classified under B01D (Separation). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2017. By volume, Korea sits between Kofax International Switzerland Sarl and Kriss Industries Asia Ltd..

Korea's three-year grant acceleration

Korea Western Power Co., Ltd. shows 4 grants in 2022–2024 against only 5 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.
