A court in Texas found that Zynga did not violate the patent rights of International Game Technology (IGT), which develops games and other software for slot machines. IGT claimed that Zynga illegally used one of its technologies in the Hit It Rich, Black Diamond Casino and Game of Thrones Slots Casino games.

The subject of the dispute was the technology by which games continue to work when the Internet connection is interrupted.

A Zynga representative told Reuters in a comment that he was glad of the court's decision, and called IGT's accusations "completely baseless." An IGT spokesperson declined to comment.

The proceedings between the companies lasted two years.
