What this shows Wenzhou's Innovation Score is 54.1/100 (top 8% 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 Wenzhou?

Each dot is one of Wenzhou’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). Wenzhou’s own 5.3 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Wenzhou's grant cadence moved

Between 2020–2024, Wenzhou University received 31 grants versus 8 in 2015–2019 (+288% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2023 at 11 grants and bottomed in 2015 at 1. Lead class G06F accounts for 24% of the portfolio across 55 subclasses. Volume neighbours: Unilin Bvba (#6,721) and medmix Switzerland AG (#6,729).

Wenzhou's three-year grant acceleration

Wenzhou University shows 24 grants in 2022–2024 against only 13 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.
