Where Ningbo's grants concentrate

Ningbo Wentai Sport Equipment Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 66.7% of grants classified under B62B (Hand-propelled Vehicles, e.g. Hand Carts OR PERAMBULATORS; Sledges). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Ningbo sits between Nimbus Iris, Inc. and Nippon Paint Marine Coatings Co., Ltd..

Ningbo's three-year grant acceleration

Ningbo Wentai Sport Equipment Co., Ltd. shows 2 grants in 2022–2024 against only 2 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.
