Where Guangdong's grants concentrate

Guangdong Laijun Electronic Technology Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 40% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2024. By volume, Guangdong sits between Guangdong Institute OF Applied Biological Resources and Guangdong Yuhao Electronics Co., Ltd..

Guangdong's three-year grant acceleration

Guangdong Laijun Electronic Technology Co., Ltd. shows 5 grants in 2022–2024 against only 0 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.
