What this shows D's Innovation Score is 39.4/100 (top 38% 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 5.9 claims/patent is at or below the 15.8 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 Group PTY Ltd is a focused PatentsView assignee: 11 CPC subclasses with 27.8% of grants classified under E05C (Bolts OR Fastening Devices FOR Wings, Specially FOR Doors OR Windows). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2016. By volume, D sits between Cosmo Technologies Ltd. and Duke Energy Corporation.

D's three-year grant acceleration

D & D Group PTY Ltd shows 14 grants in 2022–2024 against only 8 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.
