American California beef noodles, also known as "California beef noodles", include several Chinese fast food chain restaurants that accuse each other of infringement.

Wu Jinghong, an overseas Chinese who was engaged in the catering industry in the United States, returned to China in 1985 and founded the first "California Beef Noodle King". The trademark was registered in China in 1993. The trademark was registered in the United States in 1996 and belongs to the American Hongli International Company owned by Wu Jinghong. The founder of another "Mr. Li's California Beef Noodle House" is Li Beiqi, a Chongqing native and an overseas Chinese from California. From 1972 to 1974, he used the name "Beef Noodle King" and opened three "Beef Noodle King" restaurants in Chinatown, Monterey Park, and Alhambra in the Los Angeles area. By 1979, it expanded to seven restaurants. Later, he opened a specialty store in China under the trade name "California Beef Noodle King". California beef noodles are not common in the United States. The raw materials of the above two "California beef noodles", including noodles, beef, spices, and production techniques, all come from China. The name "California, USA" is just a marketing ploy.
