What this shows Darex's Innovation Score is 52.2/100 (top 10% 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 Darex?

Each dot is one of Darex’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). Darex’s own 12.9 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Darex's grants concentrate

Darex, LLC is a focused PatentsView assignee: 8 CPC subclasses with 43.1% of grants classified under B24B (Machines, Devices, OR Processes FOR Grinding OR Polishing ; Dressing OR Conditioning OF Abrading SURFACES; Feeding OF Grinding, Polishing, OR Lapping Agents). Peak complete grant year is 2024 (16 grants) versus a trough of 2 in 2020. By volume, Darex sits between Cigna Intellectual Property, Inc. and Envision Aesc Japan Ltd..

Darex's three-year grant acceleration

Darex, LLC shows 30 grants in 2022–2024 against only 10 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.
