The current Sonos patent for this claims that they first filed in April 2004, and the patent under which they sued Google derives from that: "System And Method For Synchronizing Operations Among A Plurality Of Independently Clocked Digital Data Processing Devices”, filed Apr. 1, 2004" Full details and history on the subject patent: https://patents.google.com/patent/US8588949B2/en Bill ------------------------------------------------------------------------ ftlight's Profile: http://forums.slimdevices.com/member.php?userid=5294 View this thread: http://forums.slimdevices.com/showthread.php?t=115721
