What this shows Guangdong's Innovation Score is 25.6/100 (18th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Guangdong?

Each dot is one of Guangdong’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Guangdong’s own 12.0 claims/patent is ABOVE the 9.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guangdong's grants concentrate

Guangdong Yuhao Electronics Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 80% of grants classified under F21S (Non-portable Lighting DEVICES; Systems THEREOF; Vehicle Lighting Devices Specially Adapted FOR Vehicle Exteriors). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Guangdong sits between Guangdong Laijun Electronic Technology Co., Ltd. and Guangzhou Changen Electronic Technology Co., Ltd.

Guangdong's three-year grant acceleration

Guangdong Yuhao Electronics Co., Ltd. shows 1 grants in 2022–2024 against only 3 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.
