What this shows Guangzhou's Innovation Score is 41.5/100 (top 33% 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 11.0 claims/patent is ABOVE the 8.8 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 Institute OF Building Science Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 60% of grants classified under E02D (FOUNDATIONS; EXCAVATIONS; Embankments ; Underground OR Underwater Structures). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2016. By volume, Guangzhou sits between Guangzhou Changen Electronic Technology Co., Ltd and Guangzhou Woya Laideling Technology Co., Ltd..

Guangzhou's three-year grant acceleration

Guangzhou Institute OF Building Science Co., Ltd. shows 3 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.
