Where Wangs's grants concentrate

Wangs Alliance Corporation is a focused PatentsView assignee: 20 CPC subclasses with 50.8% 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 2023 (40 grants) versus a trough of 1 in 2017. By volume, Wangs sits between Self Electronics Co., Ltd. and Basf Plant Science Company GmbH.

Wangs's three-year grant acceleration

Wangs Alliance Corporation shows 81 grants in 2022–2024 against only 16 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.
