Since Budweiser grew, the trademark dispute between Budweiser and Czech Budweiser has never stopped. Since the first lawsuit in 1894, a long trademark war has started between the two convenience companies, and various lawsuits have spread all over Europe. In 197, Shuangfa reached a basic agreement, stipulating that Anheuser-Busch could use the "Budweiser" trademark in North America. But at that time, Czech Budweiser completely underestimated the strength of American Budweiser, because its expansion speed was too fast. In 1911 and 1939, the two sides signed an agreement again, stipulating that Anheuser-Busch could use the "Budweiser" trademark outside Europe, while in Europe it was used by two Budweiser wineries in the Czech Republic. Subsequently, the expansion momentum of Budweiser in the United States went to the world. With the defeat of various lawsuits, the scope of use of Budweiser in the Czech Republic was gradually shrinking. In the 199s, EU judges held that the two kinds of beer were completely different in style, and trademarks would not cause confusion. In 29, after joining InBev (InBev), the world's largest beer, American Budweiser really established itself in Europe, and its brand was greatly promoted, while the naming right of Czech Budweiser was almost only in the Czech Republic. In the Czech Republic, American Budweiser must be renamed Bud, which is the abbreviation of Budweiser. Although Budweiser in the United States already has a strong commercial ability, it has proposed to buy Budweiser winery in the Czech Republic several times, but the government has always disagreed, no matter how high the price is. In their eyes, Czech Budweiser beer has become a symbol of Czech beer and even the Czech country, although the market is almost squeezed to its own country.
