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 12.8 claims/patent is ABOVE the 7.9 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 Iwiss Electric Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 62.5% of grants classified under B25B (Tools OR Bench Devices NOT Otherwise Provided FOR, FOR Fastening, Connecting, Disengaging OR Holding). By volume, Zhejiang sits between Zebware AB and Zhejiang Shaoxing Supor Domestic Electrical Appliance Co., Ltd..

Zhejiang's three-year grant acceleration

Zhejiang Iwiss Electric Co., Ltd. shows 6 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.
