Where Dellner's grants concentrate

Dellner Couplers AB is a focused PatentsView assignee: 13 CPC subclasses with 63.6% of grants classified under B61G (COUPLINGS; Draught AND Buffing Appliances). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2016. By volume, Dellner sits between Dowa Holdings Co., Ltd. and Dollar Shave Club, Inc..

Dellner's three-year grant acceleration

Dellner Couplers AB shows 8 grants in 2022–2024 against only 8 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.
