What this shows Wuhan's Innovation Score is 64.1/100 (top 2% 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 Wuhan?

Each dot is one of Wuhan’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). Wuhan’s own 6.8 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Wuhan's grant cadence moved

Between 2020–2024, Wuhan University OF Technology received 60 grants versus 7 in 2015–2019 (+757% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2024 at 25 grants and bottomed in 2015 at 1. Lead class C04B accounts for 14.3% of the portfolio across 81 subclasses. Volume neighbours: Umm-Al-Qura University (#4,591) and Arcadyan Technology Corporation (#4,599).

Wuhan's three-year grant acceleration

Wuhan University OF Technology shows 50 grants in 2022–2024 against only 14 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.
