Aristocrat Tech., Australia v. Int’l Game Tech.

The patent, entitled “Slot Machine Game and System with Improved Jackpot Feature,” issued in 2006 and relates to a system of linked gaming machines through which an allegedly improved jackpot mechanism is provided to a player. Incremental jackpots are well known in the prior art, but the patent claims that prior art systems lack flexibility in both operator control and ability to tailor prizes to player preferences, through a bonus game that may appear. The district court granted summary judgment of noninfringement, explaining that the accused products require two separate actors, the casino via the gaming machine and the player, and that the lack of a single entity performing all of the steps of the asserted claims precluded direct infringement as a matter of law. The Federal Circuit affirmed the district court’s claim constructions and its ruling on direct infringement but, in light of an intervening decision, vacated and remanded the ruling on indirect infringement.
