What this shows Delk's Innovation Score is 21.5/100 (9th 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 Delk?

Each dot is one of Delk’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). Delk’s own 7.7 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Delk's grants concentrate

Delk Industries is a focused PatentsView assignee: 1 CPC subclasses with 33.3% of grants classified under B60J (Windows, Windscreens, Non-fixed Roofs, Doors, OR Similar Devices FOR VEHICLES; Removable External Protective Coverings Specially Adapted FOR Vehicles). By volume, Delk sits between Degelman Industries LP and Denovo Biopharma, LLC.

Delk's three-year grant acceleration

Delk Industries shows 2 grants in 2022–2024 against only 2 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.
