Where Doubleday's grants concentrate

Doubleday Acquisitions, LLC is a focused PatentsView assignee: 13 CPC subclasses with 55.6% of grants classified under F25D (REFRIGERATORS; Cold ROOMS; ICE-BOXES; Cooling OR Freezing Apparatus NOT Otherwise Provided FOR). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2017. By volume, Doubleday sits between Dongguan Kaishuo Electronics Technology Co., Ltd. and Drive Cjsc.

Doubleday's three-year grant acceleration

Doubleday Acquisitions, LLC shows 2 grants in 2022–2024 against only 4 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.
