What this shows University's Innovation Score is 46.9/100 (top 20% 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 University?

Each dot is one of University’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). University’s own 12.3 claims/patent is at or below the 18.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where University's grants concentrate

University of South China is a focused PatentsView assignee: 13 CPC subclasses with 33.3% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2022 (3 grants) versus a trough of 2 in 2024. By volume, University sits between University of Connecticut Health Center and University of the Witwatersrand.

University's three-year grant acceleration

University of South China shows 5 grants in 2022–2024 against only 0 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.
