What this shows Guangzhou's Innovation Score is 44.9/100 (top 24% 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 1.5 claims/patent is at or below the 18.8 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 Issyzone Technology Co., Limited is a focused PatentsView assignee: 9 CPC subclasses with 2.1% of grants classified under B60J (Windows, Windscreens, Non-fixed Roofs, Doors, OR Similar Devices FOR VEHICLES; Removable External Protective Coverings Specially Adapted FOR Vehicles). Peak complete grant year is 2023 (9 grants) versus a trough of 1 in 2021. By volume, Guangzhou sits between Fate Therapeutics, Inc. and Gingy Technology Inc..

Guangzhou's three-year grant acceleration

Guangzhou Issyzone Technology Co., Limited shows 18 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.
