Where Guangzhou's grants concentrate

Guangzhou Ehang Intelligent Technology Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 11.1% of grants classified under G05D (Systems FOR Controlling OR Regulating Non-electric Variables). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2019. By volume, Guangzhou sits between Group IB, Ltd and Guangzhou Yajiang Photoelectric Equipment Co., Ltd..

Guangzhou's three-year grant acceleration

Guangzhou Ehang Intelligent Technology Co., Ltd. shows 1 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.
