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 7.9 claims/patent is ABOVE the 2.0 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 Shaoxing Supor Domestic Electrical Appliance Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 37.5% of grants classified under A47J (Kitchen EQUIPMENT; Coffee MILLS; Spice MILLS; Apparatus FOR Making Beverages). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2021. By volume, Zhejiang sits between Zhejiang Iwiss Electric Co., Ltd. and Zimplistic Pte. Ltd..

Zhejiang's three-year grant acceleration

Zhejiang Shaoxing Supor Domestic Electrical Appliance Co., Ltd. shows 7 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.
