JPEG Patent Could Impact The Gimp

SeanAhern writes "A number of years ago, Forgent acquired a patent on some of the algorithms required for JPEG compression and decompression, and recently sued 31 big-name IHVs and ISVs. A Newsforge article gets into some of the details and asks whether open source tools like the Gimp could be liable as well. To add fuel to the fire, the Joint Photographic Experts Group's committee thinks that some of the patent may be invalid. The p2pnet.net story mentions that the FTC has some skepticism as well. We originally talked about this on Slashdot back in the summer of 2002."

      except that the LZW patent was valid, as far as I know.

      Both LZW and this patent are "valid" patents. Both of them had extensive related prior art at the time of their filing, although the exact method described in each patent may not have been patented before. In both cases, the only reason the patents became valuable was because the companies involved remained silent for a long time, until the patented method had become an integral part of some standard that was erroneously presumed open and freely implementable; if the existence and enforceability of either patent had been known at the time the standards were written, the standards could have trivially avoided causing implementors to infringe on the patents.

      While I will grant you that this patent looks even more stupid than LZW, the situations are quite analogous.

  2. This is a very bad trend by metlin · · Score: 4, Interesting

    From the article --


    NF: Would a free software program that stores images in JPG format, like the GIMP, be violating your IP rights by using JPG?

    Noonan: That's a difficult question, I don't have the answer to that. I have to defer that to our legal team.
    Of course, just to be safe, it might be wise for the GIMP developers (as well as all other open source image processing projects which use JPG) to volunteer to donate a percentage of their revenues to Forgent Networks.


    WTF?! What revenues? The developers are getting donations and the like for the contributions they are making by working for free. This is plain ridiculous, people are putting in their free time to help develop software that will benefit everyone, and giving it away for free.

    And jackasses like this want a piece of the pie? What about the good old days when knowledge belonged to the world, and people put out their works for everyone else to use?

    Yet another reasons how patents are blatantly misused. First of all, its not even sure if they have the rights that they claim to have. At the very least, they could have spared non-commercial entities.

    Stuff like this gets me worked up to no end.

    The statement notes that at least two other companies (Philips and Lucent) are similarly claiming to have patents that relate to portions of the original JPEG standard, and expresses disappointment that some organisations are trying to cash in on what was developed to be a license and royalty-free standard.

    And what has been contributed by the OpenSource community to benefit everyone else, is being made useless by pointless litigations.

    Remember kids - We now live in an era where giving away knowledge and helping people is WRONG! You need to be greedy, patent all your stuff, sue your Mom and kill your neighbour's dog is RIGHT.

    I'm not so worried about The Gimp, since I typically use Photoshop.

    What I AM worried about, is what sort of long-reaching implications this has for GD. I use GD regularly in order to manipulate images via the web, and something like this would most likely cause JPEG support to be entirely removed from the project until the worldwide patent expires.

    They did it with GIF.

    This sucks, because usually I've come to expect future versions of software to have MORE functionality, not less. I hope the Joint Photographic Experts Group really does have prior art.

  5. Some of this old documentation is screwy by Amiga+Lover · · Score: 4, Interesting

    Seriously. Half these patent/IP battles with stuff from the 80s/early 90s is crap - companies have some IP they claim is theres, but looking back it's been so diluted over time, pieces sold off, transferred about, and nobody really keeps records of what belongs to who. SCO think they own "unix" but they at the most (barring the novell dispute) own PART of SOME of ONE branch of ONE of the unices. Some of the SysV code is so open and diluted and already released freely that it simply cannot apply, likewise by the look of these jpg patents it's only a MAYBE that forgent own SOME of the jpeg compression stuff.

    Is there not a central registry on who owns what, instead of just an initial record of a patent being granted to company X, and finding out who owns it requires looking through the transitions of different companies as pieces of the IP are sold off over time.

    If everything was kept up to date AS THE SALES HAPPENED it would all be so much easier, no disputes, a nice paper trail of just who owns what.

    I bet some of these patent companies buy up IP in the hope they have something worthwhile, but will never know what they're truly entitled to without it being decided by a court... and since information can be absent there, that can get it wrong

      The effects you are describing happens in land sales frequently. A man with x acres will give his children each an equal share in the x acres instead of splitting the land up. Then these children will borrow money against their share, sell it off, or give it to their children. After 20 - 30 years the shares are all split up and dilluted until someone comes along and forcloses on one share with an outstanding debt and is able to take all of the property. (There is an 8 year perdiod where the forclosure can be challenged but it is hard to succesfully execute after the forclosure is complete and impossible after 20 years). The term for this 8-20 year period is a colored title. (0-8 years I think is a contested title and 20 on is a clear title).

    quantization is just lossy scailing (how they can patent scailing?). Huffman is patent free. That leaves DCT, but isn't that just _very basic_ transform?

    And if they parent jpeg, doesn't it also mean they have the rights to low/high pass image filters?

    Am I missing something? (sorry, don't really wanna read through the patent to figure out... would just like to get a quick clue on what's this all about...)

    That's not really the case with copyrights. If you give someone a license to a copyright, and the license didn't specify a way for you to revoke it, then you or future owners of the copyright can't turn around and revoke it. (I remember hearing of some exception to this designed to allow musicians to renegotiate after a number of years, but in general...).

    When this gets to court, it may come down to the defendants saying, "We were told this was OK, no fair changing your mind." And hopefully the court will agree with that. Yes, it's too bad you can't easily disclaim a subset of your patent rights in a more binding way.

    Actually, the GIMP team should assign a monetary value to the work they put into the project, and since they are giving it away, that constitutes negative revenue. Let's say for instance they'll donate 15% and let's pick an arbitrary value of the work that went into creating/maintaining the software at (pinky up to cheek) $1M. That means that revenues are negtative $1M. 15% of that is $150K that Forgent owes yo the GIMP team.
