IGT v. Alliance Gaming Corp., No. 11-1166 (Fed. Cir. 2012)Annotate this Case
IGT owns patents related to “wheel games,” casino gaming machines containing a secondary bonus game incorporating a spinning wheel. IGT sued Bally for infringement and Bally counterclaimed under state and federal antitrust laws. The district court denied motions for summary judgment on the antitrust issues, granted the motions that the patents were invalid and not infringed, and certified the patent issues for interlocutory appeal. The Federal Circuit affirmed. On remand, the district court granted summary judgment against Bally on its antitrust counterclaims. The Federal Circuit affirmed, stating that the undisputed facts were insufficient to establish the existence of a relevant antitrust market in wheel games.
