Does more volume mean deeper claims for Weidmann?
Each dot is one of Weidmann’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). Weidmann’s own 19.6 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Weidmann's grants concentrate
Weidmann Holding AG is a focused PatentsView assignee: 10 CPC subclasses with 57.1% of grants classified under D21C (Production OF Cellulose BY Removing Non-cellulose Substances From Cellulose-containing MATERIALS; Regeneration OF Pulping LIQUORS; Apparatus Therefor). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2019. By volume, Weidmann sits between Waters Industries, Inc. and Wells Lamont Industry Group LLC.
Weidmann's three-year grant acceleration
Weidmann Holding AG shows 2 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.
