What this shows Zhejiang's Innovation Score is 58.4/100 (top 5% 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 8.7 claims/patent is at or below the 12.6 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 University OF Science AND Technology is a focused PatentsView assignee: 41 CPC subclasses with 15% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2020. By volume, Zhejiang sits between Yantai Shougang Magnetic Materials Inc and eChem Solutions Corp..

Zhejiang's three-year grant acceleration

Zhejiang University OF Science AND Technology shows 11 grants in 2022–2024 against only 3 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.
