Apple has recently been confronted by two companies that say Apple is infringing on their patents with its popular iTunes and iPod products.
A Hong Kong-based company called Pat-rights claims its holds a patent on the digital rights management (DRM) process that Apple uses in the iTunes Music Store and iPod.
The company is demanding 12 percent of Apple’s gross revenue from iTunes and iPods. Pat-rights said it will file a lawsuit on March 21 if the company and Apple do not reach an agreement before then.
Meanwhile, Illinois-based Advanced Audio Devices, has reportedly sued Apple, claiming that the company’s iPod violates one of its patents. A Chicago Tribune article is scant on details, but the paper does say that Advanced Audio told Apple in December that the iPod infringed on its “Music Jukebox” patent.
