Northern District of California Judge James Ware has dismissed with prejudice a putative class action alleging that Apple Inc. violated the antitrust laws by updating its iTunes media player software to thwart programs that would have removed encryption from music files sold through the iTunes Music Store. The suit, filed on behalf of Itunes music purchasers, claimed that Apple maintains a monopoly over digital music file sales through updates to its digital rights management file encoding software that prevented competitors from entering the market. Relying on a previous ruling, the court held that Apple’s adopting and maintaining its system did not violate the antitrust laws.
