IGT Sues Competitor

By  | 

International Game Technology has sued Bally Technologies Incorporated, claiming one of its rival's lines of gambling products infringes on I-G-T patents.
In the lawsuit filed in federal court in Delaware, the
Reno-based slot maker claims Bally products that offer
system-driven bonuses for casino "slot club" gamblers infringe on
at least nine I-G-T patents.
Also named in the suit announced today by I-G-T were Bally
subsidiaries Bally Gaming International and Bally Gaming.
Officials for Las Vegas-based Bally declined to comment.
At issue is "Bally Power Bonusing" technology used to reward
loyal gamblers. Such systems award bonus points that can be
redeemed differently at casinos.
The suit seeks an unspecified amount of monetary damages, a
preliminary and permanent injunction, and a finding of
Bally also was slapped with two 2004 patent infringement
lawsuits involving I-G-T. Both cases are still pending in federal
court in Nevada.
