Does more volume mean deeper claims for Wenzhou?

Each dot is one of Wenzhou’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). Wenzhou’s own 1.0 claims/patent is at or below the 10.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wenzhou's grants concentrate

Wenzhou Guolong Sanitary Ware Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2022. By volume, Wenzhou sits between Wuyi Instinct Outdoor Products Co., Ltd. and WiChorus, Inc..

Wenzhou's three-year grant acceleration

Wenzhou Guolong Sanitary Ware Co., Ltd. shows 10 grants in 2022–2024 against only 0 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.
