Does more volume mean deeper claims for D4D?

Each dot is one of D4D’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). D4D’s own 12.2 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where D4D's grants concentrate

D4D Technologies, LLC is a focused PatentsView assignee: 8 CPC subclasses with 76.5% of grants classified under A61C (DENTISTRY; Apparatus OR Methods FOR Oral OR Dental Hygiene). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2016. By volume, D4D sits between Critical Innovations, LLC and Decor Grates Incorporated.

D4D's three-year grant acceleration

D4D Technologies, LLC shows 6 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.
