In terms of patent litigation, WWB Corporation appears solely as a defendant in one tracked case, indicating its posture as an operating company defending against infringement allegations. The case, Shanghai Jinko Green Energy Enterprise Management Co LTD et al. v. VSUN Solar USA Inc. et al., was filed in the United States District Court for the Northern District of California.
WWB Corporation, along with its parent Abalance Corporation and Fuji Solar Co., Ltd., was sued by Chinese solar panel manufacturer JinkoSolar over alleged infringement of N-type tunnel oxide passivated contact (TOPCon) solar cell patents. WWB Corporation successfully moved to dismiss the complaint against it for lack of personal jurisdiction, asserting that it sells its Maxar solar panels exclusively in the Japanese market and does not sell, advertise, or solicit business in the United States.
