What this shows Guangzhou's Innovation Score is 38.8/100 (top 40% 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 4.3 claims/patent is at or below the 13.9 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 Roiskin Technology Company is a focused PatentsView assignee: 5 CPC subclasses with 30% of grants classified under A45C (PURSES; LUGGAGE; Hand Carried Bags). Peak complete grant year is 2024 (5 grants) versus a trough of 2 in 2023. By volume, Guangzhou sits between Guangdong Yingao Kitchen Utensils Co., Ltd. and Gagemaker, LP.

Guangzhou's three-year grant acceleration

Guangzhou Roiskin Technology Company shows 10 grants in 2022–2024 against only 0 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.
