"We continue our efforts to secure our Budweiser trademark rights in Italy. To do so we are considering our legal options," spokeswoman Karen Couck said in a statement emailed to the AP.
"We will transition to the Bud brand in Italy to make sure that there is no disruption in the supply of our world famous beer to our loyal consumers until we are able to secure our Budweiser rights," Couck said.
Budvar's Italian lawyer Stefano de Bosio said the verdict may be a precedent for other trademark disputes because it ruled that traditional names are entitled to the same protection as current official names.
Founded in 1895 in the city of Ceske Budejovice called Budweis at the time Budvar argues that only beer brewed in its part of the Czech Republic can be called Budweiser.
Budvar said it hoped the ruling will help it boost sales in Italy which dropped in 2002 by about half after it was forced due to Anheuser-Busch's legal action to sell its beer under the name of Czechvar and later Budejovicky Budvar. In 2001, Italy was the fifth biggest market for Budvar.
Budvar has been fighting with Anheuser-Busch for over a century over use of the Budweiser brand.
The legal battle was not affected when Anheuser-Busch was taken over by Belgian brewer InBev in 2008.
