What this shows Nanjing's Innovation Score is 58.1/100 (top 5% 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 9.5 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Nanjing's grant cadence moved

Between 2020–2024, Nanjing Agricultural University received 24 grants versus 10 in 2015–2019 (+140% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2023 at 10 grants and bottomed in 2015 at 1. Lead class C12N accounts for 28.6% of the portfolio across 53 subclasses. Volume neighbours: Mavenir Systems, Inc. (#9,081) and NCR Atleos Corporation (#9,089).

Nanjing's three-year grant acceleration

Nanjing Agricultural University shows 18 grants in 2022–2024 against only 8 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.
