Where Electric's grants concentrate

Electric Power Development Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 70% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2018. By volume, Electric sits between Ekra Automatisierungssysteme GMBH and Embraco INDÚSTRIA DE Compressores E SOLUÇÕES EM REFRIGERAÇÃO Ltda..

Electric's three-year grant acceleration

Electric Power Development Co., Ltd. shows 2 grants in 2022–2024 against only 0 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.
