What this shows Zhejiang's Innovation Score is 55.2/100 (top 7% 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 7.0 claims/patent is at or below the 8.5 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 Normal University is a focused PatentsView assignee: 33 CPC subclasses with 23.8% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2019. By volume, Zhejiang sits between Zhejiang Ocean University and i4C Innovations Inc..

Zhejiang's three-year grant acceleration

Zhejiang Normal University shows 17 grants in 2022–2024 against only 1 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.
