International Game Technology today said it scored a legal victory in part of a patent lawsuit filed in 2006 pitting IGT against competing slot machine maker Aristocrat Technologies Inc.
U.S. District Judge Ronald Whyte in the Northern District of California granted IGT's motion for summary judgment involving two patents on May 13. Aristocrat, the plaintiff in the suit, had alleged that IGT's multi-level progressive games including its Fort Knox, Jackpot Hunter, Party Time! and Wheelionaire mystery progressive systems, infringed the patents. The judge found IGT did not infringe on those patents.
Aristocrat, based in Australia, has alleged that Reno-based IGT is infringing an additional patent and has a motion pending to add that patent to the lawsuit. IGT is opposing that motion.
