Microsoft being sued by Alcatel for patent infringement

Gavels: symbolizing court battles since I-don't-know-whenThe Xbox Live Video Marketplace has only been in existence for a couple of days and Microsoft is already facing a court battle that may affect its continued service. French telecommunications company Alcatel has just filed a lawsuit against Microsoft fro alleged patent infringements.

The patents listed in the complaint are all about digital video processing, communications software and online authentication – stuff that seem pretty tied to the Xbox Live Video Marketplace. Here’s the list of contested patents so you guys can check ’em out too:

  • 6,339,830 and 6,874,090, “Deterministic User Authentication Service for Communication Network”
  • 6,661,799, “Method And Apparatus for Facilitating Peer-to-Peer Application Communication”
  • 6,823,390, “Method Of Setting Up Data Communication With A Communication Means And Furthermore Program Modules And Means Therefor”
  • 6,112,226, “Method And Apparatus For Concurrently Encoding And Tagging Digital Information For Allowing Non-Sequential Access During Playback”
  • 5,864,682 and 5,659,539, “Method and Apparatus for Frame Accurate Access of Digital Audio-Visual Information.”

Speculations also abound that this lawsuit stems from the court battle between Microsoft and Lucent which started in 2003. That was also recently revitalized due to Xbox 360 video encoding, Microsoft eventually won that case but Lucent was just acquired by Alcatel earlier this year along with the company’s whole patent portfolio.
