Does more volume mean deeper claims for Zhejiang?

Each dot is one of Zhejiang’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). Zhejiang’s own 14.4 claims/patent is ABOVE the 11.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zhejiang's grants concentrate

Zhejiang Pride Leisure Products Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 66.7% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2022 (10 grants) versus a trough of 1 in 2021. By volume, Zhejiang sits between Yanegijutsukenkyujo Co., Ltd. and Zeller Digital Innovations, Inc..

Zhejiang's three-year grant acceleration

Zhejiang Pride Leisure Products Co., Ltd. shows 16 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.
