What this shows Guangzhou's Innovation Score is 46.7/100 (top 20% 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 14.1 claims/patent is ABOVE the 9.9 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 Lianrou Machinery & Equipment Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 40% of grants classified under B68G (Methods, Equipment, OR Machines FOR USE IN UPHOLSTERING; Upholstery NOT Otherwise Provided FOR). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2017. By volume, Guangzhou sits between Greyfin LLC and Hangzhou Hikmicro Sensing Technology Co., Ltd..

Guangzhou's three-year grant acceleration

Guangzhou Lianrou Machinery & Equipment Co., Ltd. shows 6 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.
