What this shows South's Innovation Score is 47.7/100 (top 18% 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 South?

Each dot is one of South’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). South’s own 10.2 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How South's grant cadence moved

Between 2020–2024, South China Normal University received 24 grants versus 9 in 2015–2019 (+167% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2021 at 12 grants and bottomed in 2017 at 1. Lead class G02B accounts for 33.3% of the portfolio across 50 subclasses. Volume neighbours: Shenzhen Keya Medical Technology Corporation (#8,915) and Sense Labs, Inc. (#8,923).

South's three-year grant acceleration

South China Normal University shows 11 grants in 2022–2024 against only 18 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.
