The ‘088 Patent relates to a gaming system in which a second game played on an interactive sign is triggered once specific events occur in a first game. On November 2, 2012, MGT Gaming filed a lawsuit in the United States District Court for the Southern District of Mississippi (Jackson Division) alleging patent infringement against multiple companies believed to be violating the ‘088 Patent. The lawsuit alleges the defendants Caesars Entertainment (NASDAQ GS: CZR), MGM Resorts International, Inc. (NYSE: MGM), WMS Gaming, Inc. - a subsidiary of WMS Industries, Inc. (NYSE: WMS), Penn National Gaming, Inc. (NASDAQ GS: PENN), and Aruze Gaming America, Inc. either manufacture, sell or lease gaming systems in violation of MGT Gaming's patent rights, or operate casinos that offer gaming systems in violation of MGT Gaming's patent rights. An amended version of the complaint was later filed on December 17, 2012. The allegedly infringing products manufactured, distributed, used, sold and/or offered for sale by defendants include at least those identified under the trade names: "Pirate Battle," "Battleship," "Clue," "Monopoly," "Rich Life," "Amazon Fishing Competition," "Massive Fishing Competition," "Big Game Competition," "Jackpot Battle Royal," "Wizard of Oz Journey to Oz," "The Great and Powerful Oz," and "Paradise Fishing." On January 3, 2013, WMS (joined by Caesars and MGM) moved to sever the litigation against each defendant into separate actions and to transfer the action against WMS to the Northern District of Illinois and to dismiss the case. Later that same month defendants Aruze Gaming America, Inc. and Penn National Gaming, Inc. filed motions to dismiss and motions to transfer venue to Nevada and Pennsylvania, respectively. Responsive and reply briefs have been filed and these motions are now fully briefed. As of August 6, 2013, the court has not made any decisions on these motions. In addition, on March 21, 2013, Aruze filed a separate action in Nevada seeking a declaratory judgment that Aruze does not infringe the '088 Patent and/or that the '088 Patent is invalid or unenforceable.
