What this shows Enel's Innovation Score is 47.8/100 (top 18% 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 Enel?

Each dot is one of Enel’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). Enel’s own 21.6 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Enel's grants concentrate

Enel X S.R.L. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). By volume, Enel sits between Endo Ventures Limited and EnergyNest AS.

Enel's three-year grant acceleration

Enel X S.R.L. shows 4 grants in 2022–2024 against only 0 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.
