Where Dongguan's grants concentrate

Dongguan Miray E-Tech Co., Ltd is a focused PatentsView assignee: 9 CPC subclasses with 66.7% of grants classified under F21Y (Indexing Scheme Associated With Subclasses F21k, F21l, F21s and F21v, Relating TO THE Form OR THE Kind OF THE Light Sources OR OF THE Colour OF THE Light Emitted). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2019. By volume, Dongguan sits between Dino Paoli S.r.l. and Dow Quimica De Colombia S.A..

Dongguan's three-year grant acceleration

Dongguan Miray E-Tech Co., Ltd shows 4 grants in 2022–2024 against only 2 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.
