What this shows Zhejiang's Innovation Score is 31.2/100 (37th percentile 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 6.5 claims/patent is at or below the 10.0 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 E-P Equipment Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 30.8% of grants classified under B66F (Hoisting, Lifting, Hauling OR Pushing, NOT Otherwise Provided FOR, e.g. Devices Which Apply A Lifting OR Pushing Force Directly TO THE Surface OF A Load). Peak complete grant year is 2020 (16 grants) versus a trough of 3 in 2023. By volume, Zhejiang sits between Yoti Holding Limited and 360 Electrical, L.L.C..

Zhejiang's three-year grant acceleration

Zhejiang E-P Equipment Co., Ltd. shows 10 grants in 2022–2024 against only 16 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.
