What this shows Energy's Innovation Score is 35.7/100 (top 48% 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 Energy?

Each dot is one of Energy’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). Energy’s own 13.8 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Energy's grants concentrate

Energy Focus, Inc. is a focused PatentsView assignee: 17 CPC subclasses with 64.7% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2020. By volume, Energy sits between Elbit Systems ELECTRO-OPTICS—ELOP Ltd. and Etex Services NV.

Energy's three-year grant acceleration

Energy Focus, Inc. shows 3 grants in 2022–2024 against only 7 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.
