Does more volume mean deeper claims for Dupray?

Each dot is one of Dupray’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). Dupray’s own 12.4 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dupray's grants concentrate

Dupray Ventures Inc. is a focused PatentsView assignee: 2 CPC subclasses with 42.9% of grants classified under A47J (Kitchen EQUIPMENT; Coffee MILLS; Spice MILLS; Apparatus FOR Making Beverages). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2022. By volume, Dupray sits between Ducati Motor Holding S.P.A. and Dynapar Corporation.

Dupray's three-year grant acceleration

Dupray Ventures Inc. shows 7 grants in 2022–2024 against only 0 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.
