Wolong Electric Group Co. Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 63.6% of grants classified under H02P (CONTROL OR REGULATION OF ELECTRIC MOTORS, ELECTRIC GENERATORS OR DYNAMO-ELECTRIC CONVERTERS; CONTROLLING TRANSFORMERS, REACTORS OR CHOKE COILS). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2019. By volume, Wolong sits between Wevo, Inc and World Champion Fantasy Inc..
Wolong Electric Group Co. Ltd. shows 5 grants in 2022–2024 against only 4 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.
