A company called Premier International Associates has filed suit against a slew of tech companies over infringement on two of the company’s patents. Microsoft, Verizon, AT&T, Sprint, Dell, Lenovo, Toshiba, Viacom, Real, Napster, Samsung, LG, Motorola, Nokia, and Sandisk are named in one of the two suits filed this week, while Hewlett-Packard, Acer, Gateway, and Yahoo are named in another. All of the above companies are accused of violating Premier’s patents for an electronic “List building system”—the older of which was applied for in 1997 and issued in 2001.

The patents describe what essentially comes down to a playlist. “A plurality of works can be collected together in a list for purposes of establishing a play or a presentation sequence. The list can be visually displayed and edited,” reads the “725″ patent. Both of them describe ways to graphically display an arrangement of songs from CDs or any manner of media that can then be played back sequentially or out-of-order.
