Sony BMG is seeking to recover some $12 million in damages from the Phoenix-based technology company, according to court papers filed July 3.
The music company accuses Amergence of negligence, unfair business practices and breaching the terms of its license agreement by delivering software that "did not perform as warranted."
In a statement, The Amergence Group vowed to fight what it described as unwarranted allegations by Sony BMG.
The company also suggested that lawsuits against Sony BMG over CD copy-protection primarily stemmed from Sony's use of another technology.
It began including MediaMax on some of its compact discs in August 2003 and shipped about 4 million CDs equipped with the technology in 2005.
Last fall, the company agreed to pay a total of $5.75 million to settle the litigation and resolve investigations by officials in several states.
