Does more volume mean deeper claims for Zahner?
Each dot is one of Zahner’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). Zahner’s own 4.7 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Zahner's grants concentrate
Zahner Design Group, Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 40% of grants classified under A47H (Furnishings FOR Windows OR Doors). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2015. By volume, Zahner sits between ZYA, Inc. and Zedsen Limited.
Zahner's three-year grant acceleration
Zahner Design Group, Ltd. shows 4 grants in 2022–2024 against only 1 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.
