What this shows Ningbo's Innovation Score is 39.0/100 (top 39% 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 3.4 claims/patent is at or below the 4.7 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 Aquart Electrical Appliance Co., Ltd is a focused PatentsView assignee: 5 CPC subclasses with 15.4% of grants classified under F25C (Producing, Working OR Handling ICE). Peak complete grant year is 2022 (8 grants) versus a trough of 1 in 2021. By volume, Ningbo sits between Nicolaas Josef Schoemaker e Outros and Ningbo Taller Electrical Appliance Co., Ltd..

Ningbo's three-year grant acceleration

Ningbo Aquart Electrical Appliance Co., Ltd shows 11 grants in 2022–2024 against only 1 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.
