Decade-old Advanced Audio Campaign Still Finding New Targets
Advanced Audio began its litigation campaign almost a decade ago and is still filing new cases. The most recent suit, against Pantech, asserts five patents that the entity has used in other cases. The patents-in-suit relate to various aspects of a digital music player, including storing and playing digital music tracks (6,587,403, 7,289,393, 7,817,502, 7,933,171, 8,400,888). The entity developed the patented technology as an operating company selling custom CD-recording devices, but it began asserting its patents in litigation in 2005 and its product sales appear largely inactive. Pantech’s digital audio player products are accused of infringing the patents-in-suit, similar to other products at issue in the campaign. Most of Advanced Audio’s previous suits are now closed. Previous suits targeted Amazon, HTC, Kyocera, Philips, and Toshiba. 3/28, Northern District of Illinois, 1:14cv02211

Audio Storage and Playback Campaign Revived by Advanced Audio
Nearly three years since its last filing, Advanced Audio Devices reignited its enforcement campaign with suits against Amazon, HTC, and Kyocera. The suits assert five patents, two of which were asserted in Advanced Audio’s previous litigation (6587403; 7289393; 7817502; 7933171; 8400888). The patents-in-suit relate to storage and playback of audio tracks from a personal digital audio player. In the complaints, defendants’ digital audio players are accused of infringing the asserted patents. Advanced Audio’s listed manager, Peter Keller, is the named inventor on the litigated patents. None of Advanced Audio’s previous suits are still open; they ended in dismissal with the most recent dismissal in May 2012. Previous defendants include Philips and Toshiba. 10/22, Northern District of Illinois, 1:13cv07577, 1:13cv07582, 1:13cv07585
