Does more volume mean deeper claims for Dubois?

Each dot is one of Dubois’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). Dubois’s own 20.0 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dubois's grants concentrate

Dubois Chemicals, Inc. is a focused PatentsView assignee: 17 CPC subclasses with 37.5% of grants classified under C11D (Detergent COMPOSITIONS; USE OF Single Substances AS DETERGENTS; Soap OR SOAP-MAKING; Resin SOAPS; Recovery OF Glycerol). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2015. By volume, Dubois sits between Draka Comteq France and Dynisco Instruments LLC.

Dubois's three-year grant acceleration

Dubois Chemicals, Inc. shows 1 grants in 2022–2024 against only 3 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.
