Wheel games

From the decision:

IGT owns several patents related to “wheel games,” a type of casino gaming machine containing a secondary bonus game incorporating a spinning wheel. IGT sued Alliance Gaming Corp., Bally Gaming International, Inc., and Bally Gaming, Inc. (collectively, “Bally”) for infringe- ment of these patents, and Bally counterclaimed under state and federal antitrust laws. The district court denied the 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. This court affirmed. On remand, the district court granted summary judgment against Bally on its antitrust counterclaims. Because the undis- puted facts are insufficient to establish the existence of a relevant antitrust market in wheel games, we affirm.
