What this shows Nanjing's Innovation Score is 44.3/100 (top 26% 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 9.9 claims/patent is at or below the 17.5 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 University OF Technology is a focused PatentsView assignee: 29 CPC subclasses with 30.4% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2018. By volume, Nanjing sits between Mighty Buildings, Inc. and NEC Casio Mobile Communications, Ltd..

Nanjing's three-year grant acceleration

Nanjing University OF Technology shows 5 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.
