What this shows Efficient's Innovation Score is 38.6/100 (top 40% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where Efficient's grants concentrate

Efficient Energy GMBH is a focused PatentsView assignee: 21 CPC subclasses with 88.5% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2016. By volume, Efficient sits between Davol Inc. and Elementis Specialties, Inc..

Efficient's three-year grant acceleration

Efficient Energy GMBH shows 3 grants in 2022–2024 against only 13 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.
