What this shows Guangzhou's Innovation Score is 38.1/100 (top 42% 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 9.6 claims/patent is at or below the 12.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Guangzhou's grants concentrate

Guangzhou Antu Electric Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 60% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2019. By volume, Guangzhou sits between Guangdong Welling Auto Parts Co., Ltd. and Guangzhou Huya Information Technology Co., Ltd..

Guangzhou's three-year grant acceleration

Guangzhou Antu Electric Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
