One hundred years after the first piece of litigation over Budweiser beer, four recent decisions show the battle is far from over – despite a major decision from the Court of Justice of the EU (CJ). In the first, Argentina made a final ruling that Czech brewery Budweiser Budvar cannot register its trade mark after an opposition from US brewer Anheuser-Busch. In the second and third, Budvar won cases in Bulgaria and Italy. Which was perhaps surprising, given the bigger decision earlier in the year from the CJ ruling that Budvar's geographical indication for Bud did not give it protection against competing trade marks.
