What this shows Guangzhou's Innovation Score is 35.5/100 (top 49% 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 13.9 claims/patent is ABOVE the 8.0 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 Huaduo Network Technology Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 70% of grants classified under H04N (Pictorial Communication, e.g. Television). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2017. By volume, Guangzhou sits between GTI Energy and GWO XI Stem Cell Applied Technology Co., Ltd..

Guangzhou's three-year grant acceleration

Guangzhou Huaduo Network Technology Co., Ltd. shows 4 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.
