ristocrat had alleged that IGT’s Multiway video slot games, including Aztec Temple and Carnival of Mystery video slot games, infringed the patent which was held invalid. The lawsuit was filed in the United States District Court for the District of Nevada on June 30, 2005. Judge Brian E. Sandoval entered an Order granting IGT’s motion for summary judgment on April 20, 2007.
Final judgment in favor of IGT was entered last April 23. The plaintiffs in the lawsuit were Aristocrat Technologies Australia PTY Limited and its US subsidiary, Aristocrat Technologies.
On the other hand, Aristocrat informed that the company believes that its patent is valid and will be promptly pursuing all appropriate appellate remedies. The firm said it is disappointed with this decision and looks forward to having this matter promptly heard and resolved in the US patent appeal court, the Federal Circuit.
"IGT believes strongly in the United States patent system and respects the valid intellectual property rights of others. We are pleased that our position has been vindicated," said Stephen W. Morro, IGT’s President - Gaming Division.
In an official press release, the Australian giant said: “Aristocrat’s 243 Ways/Reel Power patents, which are issued and pending in several countries world-wide protect valuable intellectual property which IGT have and continue to infringe. Aristocrat will continue to protect its intellectual property rights in all of its world-wide markets."
