Where Energizer's grants concentrate

Energizer Auto, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 18.2% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2021 (6 grants) versus a trough of 2 in 2022. By volume, Energizer sits between Element 1 Corp and Epirus, Inc..

Energizer's three-year grant acceleration

Energizer Auto, Inc. shows 12 grants in 2022–2024 against only 6 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.
