What this shows Guangzhou's Innovation Score is 36.0/100 (top 48% 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 11.1 claims/patent is at or below the 13.7 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 Seagull Kitchen AND Bath Products Co., Ltd. is a focused PatentsView assignee: 22 CPC subclasses with 71.4% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2019 (4 grants) versus a trough of 2 in 2017. By volume, Guangzhou sits between Green Refrigeration Equipment Engineering Research Center OF Zhuhai Gree Co., Ltd. and Gebr. Becker GmbH.

Guangzhou's three-year grant acceleration

Guangzhou Seagull Kitchen AND Bath Products Co., Ltd. shows 3 grants in 2022–2024 against only 6 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.
