What this shows Energy's Innovation Score is 42.3/100 (top 31% 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 71.8 claims/patent is ABOVE the 17.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Energy's grants concentrate

Energy Environmental Corporation is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under F24H (Fluid Heaters, e.g. Water OR AIR Heaters, Having Heat-generating Means, e.g. Heat Pumps, IN General). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2018. By volume, Energy sits between Ene29 S.A.R.L. and Enigmatos Ltd..

Energy's three-year grant acceleration

Energy Environmental Corporation shows 3 grants in 2022–2024 against only 2 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.
