RTLinux Patents: Issue Closed?

Anonymous Coward writes "LinuxDevices.com reports that the Free Software Foundation has reached an agreement with Victor Yodaiken which resolves what FSF considered to be a violation of GPL by the Open RTLinux Patent License. Details are not yet available, but it sounds like the clause in the license which required users of RTLinux to keep records and provide them to FSMLabs on demand was the principal source of the violation, and that the requirement is being dropped from an updated version of the RTLinux license that will be published in the next day or two. All in all, it seems like the FSF has successfuly enforced the GPL even though it was neither an owner nor co-owner of the software (i.e. the linux kernel) whose license terms were being violated. It's interesting to see this practical example of FSF in action, and bodes well for the future of GPL -- at least in a small way."

crimoid points to ZDNet coverage of the FSF's criticism of RTLinux's licensing terms, written before such a resolution was clear. Sourceforge on Thursday quoted RTLinux CEO Victor Yodaiken, CEO as saying that his company is happy to change "minor problems" with the RTLinux license, and that discussions are still going on with the FSF about those changes.

    How do you figure? The supposed breach involved someone who is a part of the community. Presumably he shares at least some of the same views as those espoused within the GPL. That means it was a fairly good bet that he would deal with this (in an amicable manner) once it became apparent that he had violated the GPL terms.

      Yes, but the more the FSF and GPL are seen as enforceable in a business content (even if the 'business' who agrees to abide by the GPL is one of 'us') the more bigger business who isn't one of 'us' will see it as not worth taking on the FSF and GPL.

    "Owner" as in owner of the copyright. Contrary to popular opinion, Linux and other GPL software is actually copyrighted. The GPL is essentially a EULA, and has no legal force unless the program it is included with is copyrighted. Since the FSF did not write the Linux kernel, they have no copyright on it and therefore no legal rights to it, so their power is limited in this matter. Presumaby Linus Torvalds holds the Linux copyright, but I really don't know. Probably it's co-owned by several people, but it does *not* include everyone who's ever submitted a patch.

      Two guesses:

      • Linus may already be allowing them to use the term "RTLinux". Some companies allow others to use their trademarked terms in certain circumstances. This does not dilute the trademark.

      • I don't think Linus has to worry about the term "Linux" being diluted. RTLinux is based on Linux and is under the GPL, so it's not like Linux is being used as a term to describe any operating system.

  6. The FSF are a bunch of real smart people by Rosco+P.+Coltrane · · Score: 4, Informative
    The bottom of the problem is that Victor should never ever have been granted a patent for RTlinux : there is plenty of prior art (DR-Multiuser-DOS, Concurrent DOS and even the current DR-DOS multitasker have been around for 15+ years and use the exact same technique). Moreover, Victor didn't "invent" all of RTlinux, his students did.

    Considering that the patent is easily breakable in court, the FSF settled with Victor very easily. Why ? because RTlinux is irrelevant : RTAI is the way to go now. It provides all that RTlinux provides and much more, and it isn't encumbered by silly patents.

    All in all, a much better move than it first appears by the FSF : they win on the PR front by making Victor change his license and they save money by not contesting a patent that isn't important anymore. Way to go guys !

  7. A Win-Win Result by Bruce+Perens · · Score: 5, Informative
    The GPL requires patents embedded in GPL code to be available for everyone's free use. This can be implemented by making the patents available for use in GPL programs. Victor thought he was already doing this, what happened here is simply the resolution of a small issue of GPL compatibility. So, Victor gets to use the patent to enforce his revenue stream and pay for more Free software, Free Software users get to use the patent for free, and as far as I can tell everyone wins.

    This is not really about enforcing the GPL, it didn't get close to that point. All we had was a short public dialogue. Enforcement is something that happens in court. I wouldn't even count an out-of-court settlement as enforcement, that's just avoiding the issue because the defandant thinks that a successful enforcement would be likely or doesn't think it's worthwhile to mess around in court. This was way far from anything like that.

    but this helps set a precedent. Too bad it's not in the legal sense. What we really need is a test case, to find some business that violated the GPL and take them to court over a big, intentional GPL violation where they'll attack the integrity of the GPL. If it survives the court case, we're in good shape and makes it likely that companies will think twice before they violate the GPL.

      True, but every time some company changes the licensing terms on software they derived from GPL'd code it's one more point on the FSF's side when they finally do meet up with a hostile infringer. Firstly it establishes a track record of the industry considering the GPL valid. Secondly, if the infringer tries to claim it's not valid because it's unreasonable, the FSF can trot out examples of the actual, reasonable changes needed to comply to rebut the infringer. It's a variation on the same principle the big boys have used: start with the small fry and the ones who don't lose much by accomodating you and build up precedent before going after larger targets.

    Copyright does not make you an owner, it makes you the beneficiary of a temporary exclusive right to copy the work. You can't own software.

    I'm suprised at the number of "this is good" posts. Actually, I'm glad that they've resolved this dispute, but all of this "hubub" should have never happened in the first place. When I read the some of the background articles on this, I noticed that Yodaiken was initially very surprised at the community reaction to his license. Although the article was worded mildly, it sounded to me like he was insulted not only by the FSF accusation but also by many of the comments posted on our own loving Slashdot. It was an obvious case of "oops, we goofed" that should have been handled by FSF sending a nice letter saying something like "Please notice that you have altered the GPL language to impose conditions on this license that are contrary to the goals of the GPL and FSF. Assuming that your work does not contain the efforts of others which are already licensed under the GPL, please considering removing this restriction or use a different license." Instead, a rather inflammatory press relese about violations of the GPL was sent out, and lots of comments about "Who are these people?" were posted.


    Yodaiken's company is a big contributor to Linux and OSS. I believe that, as such, they are due at least a modicum of respect and consideration. If polite attempts at correcting them are ineffective, you can always turn to the more heavy-handed approach later. People need to remember that if we want to be a community, we have to act like one. There will, as a matter of course, always be disagreements. Most of them can truly be solved without too much sword rattling by merely going to lunch together or something.


    No, I believe this whole thing was just rotten. It's enough of an issue to make me very cautious about using GPL on any software I may contribute. I would hate to see what would happen if I accidentally did something contrary to the goals of the FSF.
