What this shows Zhejiang's Innovation Score is 38.7/100 (top 40% 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 3.5 claims/patent is at or below the 11.3 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 Okai Vehicle Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 13.3% of grants classified under B62K (CYCLES; Cycle FRAMES; Cycle Steering DEVICES; Rider-operated Terminal Controls Specially Adapted FOR CYCLES; Cycle Axle SUSPENSIONS; Cycle Side-cars, Forecars, OR THE Like). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2020. By volume, Zhejiang sits between Z-modular Holding, Inc. and Zhongchao Special Security Technology Co., Ltd.

Zhejiang's three-year grant acceleration

Zhejiang Okai Vehicle Co., Ltd. shows 11 grants in 2022–2024 against only 4 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.
