This document summarizes a trademark dispute between Guangzhou Pharmaceutical Holdings and JDB Beverage Co. over the rights to the Wong Lo Kat herbal tea brand. Guangzhou Pharmaceutical owns the Wong Lo Kat trademark but licensed it to JDB's parent company in 1997. In 2012, the licensing agreement was invalidated due to fraud by Guangzhou Pharmaceutical's general manager. This led to ongoing litigation between the two companies over trademark infringement and unfair competition regarding JDB's use of the Wong Lo Kat brand name and red can packaging design. Courts ultimately ruled in favor of Guangzhou Pharmaceutical, finding that the Wong Lo Kat trademark and associated packaging are inseparable and that JDB's continued use constituted infringement and unfair competition.
