What this shows D's Innovation Score is 48.6/100 (top 16% 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 D?

Each dot is one of D’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). D’s own 17.0 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where D's grants concentrate

D & D Manufacturing LLC is a focused PatentsView assignee: 11 CPC subclasses with 50% of grants classified under Y02W (Climate Change Mitigation Technologies Related TO Wastewater Treatment OR Waste Management). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2015. By volume, D sits between Cypralis Limited and D. Wheatley Enterprises, Inc..

D's three-year grant acceleration

D & D Manufacturing LLC shows 4 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.
