What this shows Energy's Innovation Score is 57.8/100 (top 5% 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 19.3 claims/patent is ABOVE the 17.4 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 Vault, Inc. is a focused PatentsView assignee: 16 CPC subclasses with 71.9% of grants classified under F03G (Spring, Weight, Inertia OR Like MOTORS; Mechanical-power Producing Devices OR Mechanisms, NOT Otherwise Provided FOR OR Using Energy Sources NOT Otherwise Provided FOR). Peak complete grant year is 2024 (13 grants) versus a trough of 1 in 2022. By volume, Energy sits between Eurofilters Holding N.V. and Fabric8labs, Inc..

Energy's three-year grant acceleration

Energy Vault, Inc. shows 21 grants in 2022–2024 against only 4 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.
