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.

Does more volume mean deeper claims for Efficient?

Each dot is one of Efficient’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Efficient’s own 15.8 claims/patent is ABOVE the 10.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
