    ** AFAIK - the suit is not over use of the MP3 compression format as such.


    ** MP3 is done in software in a PC.

    Only MP3 decoding is a defined standard.

    An MP3 encoder is open to creative (software) design.

    A few of the "pods" support the format, so I gather there is a chip
    that can be used to support it.

    How about finding out what the law suit is about first ?

    The link you referenced does not support your statements.

    What chip set? All other mp3 manufacturers and users?

    Can anyone tell us what is the key fact that this law suit is?

    Hmm.. if they manage to defend it. Then it potentially covers a lot of
    things including ogg vorbis. I thought the tech originated from
    Fraunhofer.

    I thought it was Fraunhofer too. I suppose mp3s are just the Fraunhofer implementation of the
    wider concept.

    Now that it's clear what it's about....

    No. It's the underlying concept that's patented not any specific chip or
    algorithm.

    Just a follow-up thought.

    Both Sony's Minidisc and Philips' now obsolete DCC used perceptual coding techniques. Both of
    those predated the date of Alcatel-Lucent's patent.

  13. How? Isn't MP3 an algorithm and thus unpatentable?

    Anyone for OGG?

    Wikipedia says mp3 is an ISO/IEC standard.
    http://en.wikipedia.org/wiki/Mp3

    And it predates the Alcatel-Lucent patent.

    Weird.

  16. Many 'patent troll' companies now pop up, with very general patents.
    MS just lost a multi billion dollar claim of mp3, altough they did
    pay 15 M to Fraunhofer.
    I am not pro-MS, but to pester them like that should be made illegal.
    We have to modify the patent system to kill these patent trolls.
    Say tomorrow somebody comes with the patent of converting electricity to sound.
    Then every body will have to pay yet again.

    Incorrect. Patents are about implementations, the underlying math and
    physics is not patentable. Look up the statutes involved.

    I suggest you look at US software patents.

    The EU has wisely rejected same btw.

    And stop buggering about with the follow-ups you nasty piece of useless slime !

    I read that and looked as a few links and found this:

    http://www.mp3licensing.com/patents/

    Please note that patents in Europe generally run 20 years from dte of
    application. Some of the basic patents are about to drop like flies in a
    chloroform cloud. And a majority of them die within 5 years.

    It would be interesting to really see what the caims and the expiration
    dates of the various patents are. Both the Thompson and the
    Alcatel-Lucent.

    The relevant patent at issue is an American patent and I've read that
    Alacatel-Lucent played games in order to get it a retrospectively earlier date
    of issue that it was originally given !
