Where Dryfhout's grants concentrate

Dryfhout Properties, LLC is a focused PatentsView assignee: 2 CPC subclasses with 75% of grants classified under B26B (Hand-held Cutting Tools NOT Otherwise Provided FOR). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2020. By volume, Dryfhout sits between Dover Fueling Solutions UK Limited and DynaVap, LLC.

Dryfhout's three-year grant acceleration

Dryfhout Properties, LLC shows 1 grants in 2022–2024 against only 7 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.
