What this shows ETL's Innovation Score is 41.4/100 (top 33% 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 ETL?

Each dot is one of ETL’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). ETL’s own 7.4 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ETL's grants concentrate

ETL, LLC is a focused PatentsView assignee: 6 CPC subclasses with 90% of grants classified under B05B (Spraying APPARATUS; Atomising APPARATUS; Nozzles). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2020. By volume, ETL sits between Escort Inc. and Everheart Systems Inc..

ETL's three-year grant acceleration

ETL, LLC shows 9 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.
