Swiss food giant Nestlé has lost its battle to register the phrase “have a break” as a trademark after objections from US rival Mars proved successful. Nestlé, which manufactures the KitKat chocolate bar that has long been advertised with the slogan “Have a break. Have a KitKat”, had been attempted to register “have a break” as a trademark to prevent rivals from introducing a chocolate bar called “Break” or “Have a Break”. Nestlé argued that such a bar would be mistakenly associated with KitKat. Nestlé already has the phrase “Have a break, have a KitKat” registered as a trademark.
