Where Electric's grants concentrate

Electric Power Research Institute OF Guangdong Power Grid Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 62.5% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2019. By volume, Electric sits between Ekin TEKNOLOJ: Sanayi VE Ticaret Anonim Sirketi and Ellumen, Inc..

Electric's three-year grant acceleration

Electric Power Research Institute OF Guangdong Power Grid Co., Ltd. shows 4 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.
