Where Wako's grants concentrate

Wako (USA) Inc. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2018. By volume, Wako sits between Wuxi Xivi Science AND Technology Co., Ltd. and Warrior Technologies, LLC.

Wako's three-year grant acceleration

Wako (USA) Inc. 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.
