Miss Universe, Inc. filed a lawsuit on July 18, 1979 in the United States District Court for the Northern District of Georgia, Atlanta Division, against the company running the late-1970s version of the pageant, Miss Teen U.S.A., Inc., for trademark infringement over a claimed similarity with its own "Miss U.S.A." pageant title and some of its related registered trademarks. The lawsuit, "Miss Universe, Inc. v. Miss Teen U.S.A., Inc.", resulted initially in an injunction being issued on March 25, 1980 ordering Miss Teen U.S.A., Inc. to cease holding future pageants with the name "Miss Teen U.S.A." so as not to confuse people with the "Miss U.S.A." pageant. The injunction was appealed but eventually upheld. The court ruling did not invalidate any past Miss Teen USA titleholders. Miss Universe, Inc. itself did not receive a U.S. trademark registration for "Miss Teen USA" until the next decade, in 1991 (see next section). The final winner of the Miss Teen USA title before the Miss Universe Organization began its own version of the pageant was the 1982 Miss Teen USA title won by Hugrun Ragnarsson.
