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 2.7 claims/patent is at or below the 7.5 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 Weitao Electrical Appliance Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 38.5% 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 2017 (4 grants) versus a trough of 1 in 2021. By volume, Ningbo sits between Newron Pharmaceuticals S.p.A. and Novate Medical Limited.
Ningbo's three-year grant acceleration
Ningbo Weitao Electrical Appliance Co., Ltd. shows 1 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.
