What this shows Enersys's Innovation Score is 37.5/100 (top 43% 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 Enersys?

Each dot is one of Enersys’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). Enersys’s own 14.4 claims/patent is at or below the 17.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Enersys's grants concentrate

EnerSys Delaware Inc. is a focused PatentsView assignee: 7 CPC subclasses with 60% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2020. By volume, Enersys sits between Endomedix, Inc. and Enerpac UK Ltd.

Enersys's three-year grant acceleration

EnerSys Delaware Inc. shows 2 grants in 2022–2024 against only 1 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.
