Anheuser-Busch has lost another legal dispute over the use of the trademark 'Budweiser' after a New Zealand court ruled in favour of its rival Budejovicky Budvar, after AB charged the Czech brewery of violating the rules of fair trade. Anheuser is embroiled in a European wide conflict with Budvar over the use of the trademark name "Budweiser" and will see this latest decision as a major setback after reports that claimed the brewing giant had even hired private investigators to scout New Zealand stores for supplies of its rival's products.
