The European Court of First Instance has refused to extend the company's existing rights for beer due to Budvar's trademarks in Austria and Germany.
If the brewing giant had won the case, it would have gained the right to block Budvar from using the name on its beer.
An A-B Inbev spokeswoman said: "The decision has no effect on
A-B In bev's existing, extensive Budweiser trademark rights throughout
"In filing this community trademark application, this was merely an effort to further extend our Budweiser rights and gain additional protections.
"All of our Budweiser and Bud rights remain; none are cancelled by this action."
chief executive Tony Jennings said: "Whenever A-B Inbev lose a round in the trademark battle with us they usually say that nothing will stop the development of the Budweiser brand - which makes you wonder why they bother to go to law at all. "
