What this shows Fuzhou's Innovation Score is 63.7/100 (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 Fuzhou?

Each dot is one of Fuzhou’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). Fuzhou’s own 8.2 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Fuzhou's grant cadence moved

Between 2020–2024, Fuzhou University received 38 grants versus 6 in 2015–2019 (+533% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2022 at 11 grants and bottomed in 2019 at 1. Lead class B01J accounts for 22.6% of the portfolio across 69 subclasses. Volume neighbours: E.R. Squibb & Sons, L.L.C. (#6,326) and Gree Green Refrigeration Technology Center Co., Ltd. of Zhuhai (#6,334).

Fuzhou's three-year grant acceleration

Fuzhou University shows 32 grants in 2022–2024 against only 7 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.
