THQ and The Tetris Company have settled a dispute over licensing rights to Tetris. As a result, THQ has acquired the rights to publish a Tetris game for the Xbox 360 in North America and other territories (a Tetris game for the 360 was published by AQ Interactive in Japan).
The legal dispute between THQ and The Tetris Company started in 2005, when THQ accused The Tetris Company of breaching an existing licence and preventing THQ's planned release of a Tetris game for the Nintendo DS. In the interim, Nintendo published a successful Tetris game for the DS. It's not clear whether the new settlement agreement will also give THQ the right to publish Tetris games for the DS; THQ may have to be satisfied with limiting itself to the Xbox 360.
