"The first digital audio player in the world was created by one of America’s most acclaimed inventors, Elwood “Woody” Norris in 1993. Manufactured by e.Digital Corporation (then called Comp General) in early 1994 the FlashBack included removable flash memory and the first flash file system."

Even more interesting that EDIG did not name MP3 players as a specific target product for infringement, although they certainly did leave the door open. Can't think of a single product category that is more high profile than MP3 players, namely the ipod, save that for cell phones....gosh, then there are cameras etc......lol....this could be quite the pay day !
