80% of MS Server Protocols Are Unpatented

      These days with the patent office handing out patents like candy, you don't even have to do that. For instance, in the firehose there's been this story for a while http://slashdot.org/firehose.pl?op=view&id=631632 "Flip Video Camera Maker Sued For Patent Infringeme" Regarding this patent: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=5781788.PN.&OS=PN/5781788&RS=PN/5781788

      So without further ado, Claim #1 of the patent:

      1. A video codec, comprising:

      a single semiconductor chip providing for a video input connection from a camera and a video output connection to a monitor of decompressed data, and a transmit channel and a receive channel of compressed data;

      an interface connected to the chip for external connection to a separate frame memory dynamic random access memory (DRAM) and that provides for interim storage of incoming and outgoing video data; and

      a video compressor/decompressor disposed fully within the chip and connected to compress video information received from said video input connection for output on said transmit channel, and connected to decompress video information received from said receive channel for output on said video output connection;

      wherein, said compression of video information is by spatial de-correlation of intraframe information and temporal decorrelation of interframe information, and said transmit and receive channels have communication channel bit rates reduced by quantization and variable length coding
      So. Based on that, how does one compress video using a single chip (the patent has absolutely NOTHING about its implementation)? Being able to show that might make it actually look like the company actually invented something, instead, rendered to its most basic element, the patent says "anything that does stuff using only one chip plus DRAM" which is something an 8 year old could come up with, without even knowing what DRAM means.

      The patent office has long since slid past allowing "crap" to churning out patents of "pure unadulterated bullshit".

  3. Ok U'm stupid today by sm62704 · · Score: 5, Insightful

    Why should a server protocol be patented? A patent should be for something you don't want copied. If I were selling servers I'd want to interoperate with clients and other servers.

    Oh, Microsoft. Never mind, my bad.

      No, a trade secret is for something you don't want copied. A patent is for something where you want to make money off of the copies.

  5. WTF? by Blakey+Rat · · Score: 5, Insightful

    ZDNet blogger Jason Perlow and Centrify's Tom Kemp discover that 80 percent of all Microsoft server protocols are un-patented. What exactly then, did SAMBA license?

    Is this article trying to present me with the logic: 80% of protocols are un-patented, therefore SMB is un-patented?

    Because I don't see how that follows at all. Is SMB part of the 80% or part of the 20%? If you want to know what SAMBA licensed, why don't you just ask them? I'm sure they'd know...

      I agree, it does seem like they're trying to imply that there's only a 1 out of 5 chance that anything related to the Samba technical detail licensing is patented.

      Here is a relevant link:

      http://samba.org/samba/PFIF/ - The Samba licensing announcement.

      The announcement has a lot of ambiguities (and IANAL), but it appears hey agreed that:

      1) Samba Team members would receive access to protocol documentation. This information would only be available to Samba Team members, and available only under NDA
      2) Access to information would not restrict CODE that could be produced using this information
      3) It does not provide any patent coverage.
      4) However, Microsoft would provide a list of patents covering the protocols used by Samba, and keep the list updated. This provides Samba folks a way to understand exactly what methods to avoid - which infringe patents.
      5) Microsoft agreed that any patents not detailed in this list and found to be infringed cannot be "asserted" by Microsoft.

      Presumably, there are items that MS will provide for #4, so there are patents that relate to Samba.

    Well that is a weird analogy. Just to play devil's advocate, if someone wanted to license a sewer system, what possible use could they have for accessing the neighborhood toilets, from the direction of the sewer, no less?

    Some of their patents are on extremely useful ideas. For example, a few years back, they patented a method for allowing user processes to perform actions with Administrator privileges. Don't you Linux fans wish that you could license something like that?
