Mirrorsoft later sub-licensed the rights to Henk Rogers of Bullet-Proof Software to distribute "Tetris" in Japan. Around this same time, Nintendo was asked by Bullet-Proof Software with the prospect of developing a version of "Tetris" for the Game Boy, and Rogers traveled to Moscow to secure permission to distribute "Tetris" with the Game Boy. However, because Stein had secured the rights from Pajitnov directly and not from the Russian authorities, the USSR's Ministry of Software and Hardware Export stated that the console rights to "Tetris" had been licensed to nobody, and that Atari Games had only been licensed the rights to produce arcade games with the property. In April 1989, Tengen, who had previously filed an anti-trust suit against Nintendo, sued Nintendo again claiming rights to distribute "Tetris" on the NES, and Nintendo counter-sued citing infringement of trademark. In June 1989, a month after the release of Tengen's "Tetris", U.S. District Court Judge Fern Smith issued an injunction barring Tengen from further distributing the game, and further ordered all existing copies of the game be destroyed. As a result, Nintendo gained publishing rights for "Tetris" and 268,000 "Tetris" cartridges were recalled and destroyed after only four weeks on shelves.
