Operating-company assertion. The recorded assignment is from the inventors to the operating companies Fujian Nashida Electronic Inc Co and Nine Stars Group USA Inc., both of which produce and sell products embodying the claims of the patent, specifically induction trash cans. The ongoing district court case (5:24-cv-01843) where Nine Stars Group USA Inc. is a plaintiff suggests they are actively asserting their patent against a competitor, Guangzhou EKO Trading Development Co., Ltd.
