What this shows Zhejiang's Innovation Score is 37.1/100 (top 45% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

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 5.5 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhejiang's grants concentrate

Zhejiang Linya Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 16.7% of grants classified under A45B (Walking Sticks ; UMBRELLAS; Ladies' OR Like Fans). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2022. By volume, Zhejiang sits between Zencolor Corporation and Zhejiang Sanou Machinery Co. Ltd..

Zhejiang's three-year grant acceleration

Zhejiang Linya Co., Ltd. shows 4 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.
