International Game Technology, the world’s biggest slot machine maker, infringes two patents for the devices, an Australian gaming company alleged in a U.S. lawsuit.
Also sued by Lightning Box Games Pty in federal court in Chicago was the casino operator Caesars Entertainment Corp. (CZR:US)
The defendant companies are allegedly infringing Lightning Box patents related to an “electronic system for playing reel-type games,” according to the complaint.
Cited as an example was International Game’s “Sex and the City MultiPLAY Video Slot,” a machine Lightning Box says is in use at a Caesars casino in Joliet, Illinois.
Lightning Box, based in Alexandria, Australia, is seeking money damages and a court order barring the Las Vegas-based defendants from using or inducing the use of any product or system infringing the patents.
International Games’ media-relations department didn’t immediately reply to an e-mailed request for comment. Gary Thompson, a spokesman for Caesars, didn’t immediately reply to a voice-mail request for comment on the lawsuit.
The case is Lightning Box Games Pty v. International Game Technology (IGT:US), 13-cv-05423, U.S. District Court, Northern District of Illinois (Chicago).
