In a battle of biscuits, the Federal Court here ruled that the Huasin Food Industries Sdn Bhd-made Lex-branded biscuits have infringed the trademark held by Munchy Food Industries Sdn Bhd for its Lexus-branded biscuits after Malaysia’s highest court was satisfied with the fact that Munchy Food has exclusivity over the registered Lexus trademark, which Munchy Food has held since Jan 23, 1998.
