What this shows Ningbo's Innovation Score is 27.0/100 (22nd 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 10.8 claims/patent is ABOVE the 2.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ningbo's grants concentrate

Ningbo Maoli Electric Appliance Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 50% of grants classified under F21S (Non-portable Lighting DEVICES; Systems THEREOF; Vehicle Lighting Devices Specially Adapted FOR Vehicle Exteriors). By volume, Ningbo sits between Ningbo Haode PET Products Co., Ltd. and Nippon Control System Corporation.

Ningbo's three-year grant acceleration

Ningbo Maoli Electric Appliance Co., Ltd shows 1 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.
