What this shows E-xteq's Innovation Score is 32.7/100 (42nd percentile 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 E-xteq?

Each dot is one of E-xteq’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). E-xteq’s own 9.2 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where E-xteq's grants concentrate

E-xteq Europe is a focused PatentsView assignee: 9 CPC subclasses with 40% 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 2021 (3 grants) versus a trough of 1 in 2020. By volume, E-xteq sits between DuPont Electronic Materials International, LLC and Eaton Industrial Corporation.

E-xteq's three-year grant acceleration

E-xteq Europe shows 5 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.
