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 1.0 claims/patent is at or below the 17.0 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 Fourto Sanitary Products Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2024 (6 grants) versus a trough of 3 in 2021. By volume, Guangzhou sits between Green Creative, Ltd and Hemosonics LLC.
Guangzhou's three-year grant acceleration
Guangzhou Fourto Sanitary Products Co., Ltd. shows 14 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.
