Aristocrat to appeal decision

SYDNEY, Australia –- (PRESS RELEASE) -- In mid 2005, Aristocrat Leisure Limited (ASX: ALL) commenced proceedings against IGT for infringement of its U.S. Patent No. 6,093,102 relating to its 243 Ways/Reel Power technology. The infringing IGT games include IGT's "Multiway" Aztec Temple and Carnival of Mystery.

On 20 April, 2007, Aristocrat received a determination from a United States District Court in Reno, Nevada, that its U.S. Patent No. 6,093,102 relating to its 243 Ways/Reel Power technology, was invalid.

Aristocrat believes that its patent is valid and will be promptly pursuing all appropriate appellate remedies.

Aristocrat 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.

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.
