(US).- IGT announced it was granted summary judgment in a patent infringement lawsuit against Aristocrat Technologies. IGT was found not to infringe Aristocrat's US Patent Nos. 7,056,215 and 7,108,603. Aristocrat 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.


he lawsuit was filed in the United States District Court for the Northern District of California on June 12, 2006. Judge Ronald M. Whyte entered an Order granting IGT's motion for summary judgment on May 13, 2010.

The plaintiffs in the lawsuit were Aristocrat Technologies Australia PTY Limited and its U.S. subsidiary Aristocrat Technologies, Inc.
