Bally had alleged that its Lucky Wheel products embodied the claimed invention and that IGT’s "wheel" games, including its Wheel of Fortune slot machines, infringed the patent which was held invalid.
Late Wednesday Bally said the US District Court for the District of Nevada ruled its patent infringement claims were invalid due to obviousness and prior art. International Game Technology was granted summary judgment, meaning it asked the federal judge to rule on the case before a trial because of a lack of evidence.
"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 TJ Matthews, IGT’s Chairman and CEO.
The court order does not hurt existing Bally products, according to the casino equipment maker. Another lawsuit between the two companies is still pending in the same court.
