Barbie
Louis Marx and Company sued Mattel in March 1961. After licensing Lilli, they claimed that Mattel had “infringed on Greiner & Hausser's patent for Bild-Lilli’s hip joint, and also claimed that Barbie was "a direct take-off and copy" of Bild-Lilli. The company additionally claimed that Mattel "falsely and misleadingly represented itself as having originated the design". Mattel counter-claimed and the case was settled out of court in 1963. In 1964, Mattel bought Greiner & Hausser's copyright and patent rights for the Bild-Lilli doll for $21,600.
