July 31 (Bloomberg) -- 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.
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, 13-cv-05423, U.S. District Court, Northern District of Illinois (Chicago).
