What this shows DEL's Innovation Score is 48.0/100 (top 17% 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 DEL?

Each dot is one of DEL’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). DEL’s own 22.3 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where DEL's grants concentrate

DEL, LLC is a focused PatentsView assignee: 17 CPC subclasses with 71.4% of grants classified under B01D (Separation). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2016. By volume, DEL sits between Danfoss Editron OY and DG Holdings, Inc..

DEL's three-year grant acceleration

DEL, LLC shows 8 grants in 2022–2024 against only 5 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.
