Does more volume mean deeper claims for Douxmatok?

Each dot is one of Douxmatok’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). Douxmatok’s own 12.3 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Douxmatok's grants concentrate

Douxmatok Ltd is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A23L (Foods, Foodstuffs OR Non-alcoholic Beverages, NOT Otherwise Provided FOR; Preparation OR Treatment Thereof). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2017. By volume, Douxmatok sits between Dominion Engineering, Inc. and Dream Lion International Limited.

Douxmatok's three-year grant acceleration

Douxmatok Ltd shows 1 grants in 2022–2024 against only 4 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.
