What this shows Ningbo's Innovation Score is 25.3/100 (17th percentile 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 Ningbo?

Each dot is one of Ningbo’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). Ningbo’s own 1.5 claims/patent is at or below the 8.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ningbo's grants concentrate

Ningbo Yinzhou Jiasheng Pump Electric Machinery Factory is a focused PatentsView assignee: 1 CPC subclasses with 6.3% of grants classified under B05B (Spraying APPARATUS; Atomising APPARATUS; Nozzles). Peak complete grant year is 2024 (5 grants) versus a trough of 3 in 2021. By volume, Ningbo sits between Nguyen CHI Co., Ltd. and Northrop Grumman Guidance AND Electronics Company, Inc..

Ningbo's three-year grant acceleration

Ningbo Yinzhou Jiasheng Pump Electric Machinery Factory shows 5 grants in 2022–2024 against only 3 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.
