What this shows Guangzhou's Innovation Score is 32.9/100 (43rd 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 Guangzhou?

Each dot is one of Guangzhou’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). Guangzhou’s own 11.8 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guangzhou's grants concentrate

Guangzhou Yajiang Photoelectric Equipment Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 66.7% 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 2020 (2 grants) versus a trough of 1 in 2016. By volume, Guangzhou sits between Guangzhou Ehang Intelligent Technology Co., Ltd. and GUS Design Group Inc..

Guangzhou's three-year grant acceleration

Guangzhou Yajiang Photoelectric Equipment Co., Ltd. shows 3 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.
