TrackTime, LLC has filed its first lawsuit, suing Amazon (Audible) (1:18-cv-01518) over two patents generally related to generating and displaying on a mobile device a “synchronization index” providing text for audio from a multimedia file. The NPE is apparently backed by the sole named inventor of the asserted patents. TrackTime accuses first Amazon alone, and in the alternative Amazon and Audible jointly, of infringement through the provision of “software and applications supporting X-Ray Lyrics and/or X-Ray Music functionality, including but not limited to its ‘Amazon Music’ software application” and through the provision of its Amazon Kindle software and applications “supporting features referred to by Amazon as ‘Whispersync for Voice,’ ‘Kindle Books with Audible Narration,’ and/or ‘Immersion Reading’”. The plaintiff pleads extensively in support of its allegation that Amazon and/or Audible have been aware of the patents-in-suit, as applications before and as patents after issuance in October 2014.
