Where Dongguan's grants concentrate

Dongguan Empress Technology Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2019. By volume, Dongguan sits between Domino Printing Sciences Plc and Dose Health Llc.

Dongguan's three-year grant acceleration

Dongguan Empress Technology Co., Ltd. shows 3 grants in 2022–2024 against only 6 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.
