What this shows Guangzhou's Innovation Score is 36.2/100 (top 47% 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 7.1 claims/patent is at or below the 8.8 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 Construction Engineering Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 54.5% of grants classified under E04G (SCAFFOLDING; FORMS; SHUTTERING; Building Implements OR Aids, OR Their USE; Handling Building Materials ON THE SITE; Repairing, Breaking-up OR Other Work ON Existing Buildings). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, Guangzhou sits between GSK Consumer Healthcare Sarl and GVD Corporation.

Guangzhou's three-year grant acceleration

Guangzhou Construction Engineering Co., Ltd. shows 4 grants in 2022–2024 against only 2 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.
