What this shows Nanjing's Innovation Score is 35.6/100 (top 49% 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 Nanjing?

Each dot is one of Nanjing’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). Nanjing’s own 8.8 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nanjing's grants concentrate

Nanjing Normal University is a focused PatentsView assignee: 17 CPC subclasses with 69.2% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2015. By volume, Nanjing sits between Morse Micro Pty. Ltd. and Nationz Technologies Inc..

Nanjing's three-year grant acceleration

Nanjing Normal University shows 4 grants in 2022–2024 against only 4 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.
