What this shows Zhejiang's Innovation Score is 60.8/100 (top 3% 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 8.1 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Zhejiang's grant cadence moved

Between 2020–2024, Zhejiang University OF Technology received 47 grants versus 20 in 2015–2019 (+135% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2023 at 15 grants and bottomed in 2016 at 1. Lead class C12N accounts for 24.1% of the portfolio across 78 subclasses. Volume neighbours: UnitedHealth Group Incorporated (#4,496) and Bracco Imaging S.P.A. (#4,504).

Zhejiang's three-year grant acceleration

Zhejiang University OF Technology shows 38 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.
