What this shows Nanjing's Innovation Score is 48.7/100 (top 16% 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 7.0 claims/patent is at or below the 11.7 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 Forestry University is a focused PatentsView assignee: 46 CPC subclasses with 14.3% of grants classified under C07F (Acyclic, Carbocyclic OR Heterocyclic Compounds Containing Elements Other Than Carbon, Hydrogen, Halogen, Oxygen, Nitrogen, Sulfur, Selenium OR Tellurium). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2017. By volume, Nanjing sits between Metal Raptor Inc. and Nexter Munitions.

Nanjing's three-year grant acceleration

Nanjing Forestry University shows 12 grants in 2022–2024 against only 9 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.
