Where Kepco's grants concentrate

Kepco Nuclear Fuel Co., Ltd. is a focused PatentsView assignee: 37 CPC subclasses with 81.7% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2022 (10 grants) versus a trough of 3 in 2020. By volume, Kepco sits between Insurance Services Office, Inc. and Luxottica S.R.L..

Kepco's three-year grant acceleration

Kepco Nuclear Fuel Co., Ltd. shows 18 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.
