What this shows Ningbo's Innovation Score is 41.9/100 (top 32% 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 4.7 claims/patent is at or below the 6.5 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 Taller Electrical Appliance Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 30.8% of grants classified under F21V (Functional Features OR Details OF Lighting Devices OR Systems THEREOF; Structural Combinations OF Lighting Devices With Other Articles, NOT Otherwise Provided FOR). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2016. By volume, Ningbo sits between Ningbo Aquart Electrical Appliance Co., Ltd and NKT HV Cables GmbH.

Ningbo's three-year grant acceleration

Ningbo Taller Electrical Appliance Co., Ltd. shows 4 grants in 2022–2024 against only 0 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.
