Patent holding firm Personal Audio LLC is suing Apple for patent infringement surrounding IP covering playlist implementation on multiple Apple devices. The firm was recently awarded $8 million from Apple by a Texas judge who found that the Cupertino-based company’s iPod made unauthorized use of Personal Audio’s IP. Now, the firm’s new suit alleges that additional Apple products are infringing on the same patent. Devices covered in the new complaint include the iPhone 4, the fourth-generation iPod touch, the iPad 2, the fourth-generation iPod shuffle and the sixth-generation iPod nano. Apple has made headlines countless times over the past few months as a result of suing nearly all of its major mobile competitors for patent infringement. While some companies believe Apple should focus on building innovative products instead of suing all of its competitors, Apple seems to think its IP is being used illegally and therefore must be protected vigorously. Apparently, Personal Audio holds a similar belief.
