Where Foshan's grants concentrate

Foshan Welling Washer Motor Manufacturing Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 60% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2023. By volume, Foshan sits between Fortson-peek Company, Inc and Fourth ROW, LLC..

Foshan's three-year grant acceleration

Foshan Welling Washer Motor Manufacturing 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.
