Since the 19th century, Budweiser (like Pilsener from Pilsen (Plzeň)) became a synonym for a style of beer. This led in 1907 to the "Budweiser trademark dispute" between beer companies owning or claiming trademarks rights:
* Budweiser Bier Bürgerbräu, founded 1795 by German-speaking citizens of Budweis, was exporting Budweiser Bier to America since 1875. The company was expropriated by the communists in 1945 and changed names, but after the fall of communism reacquired old naming rights in the 1990s
* Budweiser (Anheuser-Busch), from Anheuser-Busch in the United States, has been marketed since the 1870s as "Budweiser" in United States and Canada
* Budweiser Budvar, a brewery founded in 1895 mainly by Czech-speaking citizens of Budweis (České Budějovice)
