Aristocrat to Appeal Judgment in Hyperlink Patent Infringement Lawsuit Against IGT

LAS VEGAS, NV--(Marketwire - July 13, 2010) -  Aristocrat Technologies Australia Pty Ltd today announced that it is appealing the recent judgment of non-infringement issued by a U.S. District Court in a patent infringement lawsuit. The judgment relates to a case in which Aristocrat is suing IGT for infringing certain patents covering Aristocrat's highly successful "Hyperlink" range of progressive jackpot games.

The judgment was based on an order in which the U.S. District Court for the Northern District of California found that IGT did not infringe U.S. 7,056,215 and U.S. 7,108,603. The order did not address the validity of these patents.

In addition to U.S. 7,056,215 and U.S. 7,108,603, Aristocrat's Hyperlink games are protected by further U.S. patents that were not the subject of the judgment of non-infringement. Aristocrat also expects to be issued with further U.S. Hyperlink patents in the near future. Aristocrat is committed to defending all of its Hyperlink patents.

Aristocrat's decision to appeal the judgment reflects Aristocrat's strategic and commercial commitment to enforcing its intellectual property rights.
