What this shows Zhejiang's Innovation Score is 67.1/100 (top 1% 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 8.4 claims/patent is at or below the 13.8 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 LAB is a focused PatentsView assignee: 49 CPC subclasses with 36.4% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (73 grants) versus a trough of 12 in 2022. By volume, Zhejiang sits between Postech Research and Business Development Foundation and CrowdStrike, Inc..

Zhejiang's three-year grant acceleration

Zhejiang LAB shows 115 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.
