Alan Cox Files Patent For DRM 281

Posted by kdawson
from the counter-troll dept.
booooh writes "Alan Cox has filed a patent for DRM (Digital Rights Management). From the filing: 'A rights management system monitors and controls use of a computer program to prevent use that is not in compliance with acceptable terms.' According to the patent pledge of Cox's employer Red Hat, they will not license this technology if the patent is granted. And it can probably be applied to the DRM that is in Vista. This forum has a few more details.

        I believe that the patent will be granted. The PTO doesn't see this patent as any different than the myriads of other stupid patents they routinely grant. But the only way it might not be granted is if the publicity alerts the bad guys (MS, RIAA, MPAA, etc...) that they need to spin up their lobbiests to affect the PTO. I wish this story had not been run.

        Assuming the PTO behaves as it has in the past, this patent will be granted and it will be up to litigation to sort out prior art. It will be up to Alan and Red Hat to pick who they want to attack first. If they pick somebody big, there is a serious danger that they will retaliate against Red Hat. Think about what IBM did to SCO. Every single SCO product has a patent claim infringement case against it.

        If Red Hat is smart, they'd work out a deal with a friendly party who is willing to spend the money and litigate against them first. IBM or Novell might be candidates. The idea here would be that the "defendent" would want the courts to reach a common outcome with the plaintiffs and both sides would cooperate insofar as they would force the court to pick between precedents that are favorable to both sides.

      Or the patent system will work and the patent won't be granted (prior art).
      Or the patent system will work and the patent will be granted because it is narrow in scope (only covers a specific type of DRM) which won't hurt DRM in general because no one implements it in the patented way. (If they do, prior art kills the patent)

              2) a lot of people have been working on DRM for a long time.

              Yeah, but have any of them actually produced valid, workable DRM software? I get the impression that most of them are invalidated (i.e., "cracked") within days of release. Either that, or like the Sony "rootkit DRM", the DRM was a fiasco that was quickly withdrawn due to its side-effects on customers' equipment.

              Cox and RedHat can be making the claim that all previous DRM has been poorly-functioning and/or vaporware, and they're the first ones to have actually implemented it. If so, those who support DRM should support their patent. (Whether software should actually be patentable is an independent issue.)

              There's a lot of precedent for patents for inventions that others have attempted. I recently read an interesting history of the invention of the zipper. Many people tried to invent such a mechanism in the 1800s. Their attempts generally worked for a while, but were fragile and required frequent replacement. Finally, someone came up with the zipper that we all know, which both worked and was sturdy enough to last for years in normal clothing. They got a patent on it, despite the fact that many other (poor) zipper mechanisms had already been invented. Theirs was slightly different from all the others, and it actually worked well.

              There are many stories like this in the history of technology, with many false starts before someone comes up with a good solution to a problem.

              There is another potential problem with this patent, however. It's the way that the US Patent Office now accepts patents without a working model. So it's entirely possible that Cox and RedHat are also patenting vaporware that they can't build. Do we know much about this question?

      Neither.

      Read the patent application.

      It is actually an interesting take on the licensing paradigm. Most licensing programs either start denying you access which leads to loss of data if this happens in the middle of an operation. Alternatively, they kill your program altogether which is again loss of data. Alternatively they check for licensing only when the program starts. In the days of software suspend and 200+ days of uptimes neither one of these is a good idea.

      What redhat is patenting is a three pronged approach - OS suspend, component suspend or application suspend when a license violation is encountered. The first one is obvious, the second one and third one are non-obvious until one consideres RedHat aquisition of Jboss. These actually make a lot of sense in a Jboss application.

      Overall, I am not surprised that RedHat has no intention of licensing this commercially. If they provide the relevant support, this will give a Jboss based commercial application considerable advantage over BEA and Websphere.

      The fact that Microsoft also has patents on DRM does not "protect" it in any way from this particular patent owned by Red Hat. A "defensive patent" only works to the extent that you can assert it to someone who is threatening you. So unless Red Hat starts incorporating DRM stuff in its products which infringes on Microsoft's patent, it has zero defensive value against Red Hat's patent.

      That said, Microsoft has a whole lot of other patents as well, and some of those are bound to cover code distributed by Red Hat. I just wanted to correct the misconception that holding a patent on something automatically protects your use of that stuff: it doesn't in any way, all it does is give you the right to prevent others from doing that. But it's quite possible you need umpteen other patent licenses yourself to be able to actually do what you describe in your patent application.

      Are you sure? This does not seem to be a patent for all DRM, but for a system that saves the state of the application when detecting a condition that violates the rules.

      It's not like many people don't think that anyway.

      What do you mean?

      Either way it will be proven that the patent system actually works, because a patent troll has been defeated,

      Red Hat is no patent troll. A patent troll is a company whose only business is patenting and suing for infringement. And that isn't a description of Red Hat by a long stretch.

      on top of that it will be shown that the people who most adamantly argue against patents a) don't refrain from trying to use the system to their advantage (double standard)

      So everyone that don't like the current implementation of the patent system should refrain from patenting things at all? Let's face it, patents exist and don't seem to be going away. As a corporation, refraining from patenting anything would be an invitation to competitors to sue, as you would have almost no defensive capability. Avoiding infringement altogether is about as easy as walking through a minefield, so in case you are sued, you need some defensive measures to fight off the attacker.

      file patents for other people's inventions, which we all know is STEALING (or intellectual theft or somesuch).

      A lot of patents cover the same or almost the same thing. It's a feature of the current implementation of patents, and whose patent is valid is left for the courts to decide.

      One could suspect that the system is set up only to enrich lawyers, as lawyers in the patent office earn money proportional to the number of granted patent applications. Then their patent lawyer friends earn money when corporations battle it out in court. A different implementation might require the patent office to not issue patents that cover each other, but then the lawyers would not be able to enrich themselves as much.

  • Good idea, lets publicize a patent that might have been able to slip past Apple, Microsoft, etc...

    But with totally obnoxious terms. Red Hat could enact some kind of fee whenever DRM-protected content is played, essentially turning the whole DRM world into pay-per-view. And then there would be the price increases, linked to the average price of cable TV. I even have a name for it: Digital Rights Restriction -- Genuine Annoyance Edition. It that's too long to fit in a banner ad, they could just call it "Revenue Assurance".

    The key is not to make money, it is to drive home the high cost of DRM, making the downside totally obvious to all. Remember, no matter how ridiculous the terms might be, it really won't be any worse than the copyright industry will do all by themselves in a few years. But instead of using the salami-slice method, the all-at-once/in-your-face method forces everyone to confront the issue here and now.

    I think the DRM patent is a really nifty strategy, and presented here on Martin Luther King day, no less!

    A patent is only useful if you have the money to defend the patent in court. Same with a trademark or copyright. Without lots of cash a patent is an empty threat.

      AND you have to get a judge to rule, AND you have to have the judge prosecute in a timely manner.

      Even if they were found guilty of patent infringement at some point in the future, our sad, sad "legal" system would probably just let them walk again.

      Unfortunately, Alan Cox is not a billionaire. If he were I have no doubt that he could retroactively sue aforementioned coroprations and turn a tidy profit settling out of court, but as it is he's just a regular Joe meddling in the big boys' court system.

      Unless he's granted a huge wad of cash by someone like RedHat (who I can't see wanting to be involved in a more-political-than-anything-else patent dispute that much), I don't really see this going anywhere, and in the grand scheme of things I don't think t

    I shall not comment on the likelihood of the patent being initially granted. Let's assume it is. Cox is then proposing to prevent anyone using DRM by refusing to license it to anyone on any terms. The trouble with that is such an action is grounds to cancel the patent. There are conditions in patent law designed to prevent anyone taking out patents with the objective of preventing the use of the embodied inventions. These were designed to prevent unfair competition, but will still apply.
    • ... ever added to certain standards ? If not to protect against suddenly appearing patents that kill the standard, why would they protect any standard with an agreement such as RAND [wikipedia.org] ? If it is true what you are saying, RAND is not necessary as the law can always override it.

      And even if it can override it, perhaps it is pretty difficult to achieve (plus costly...).
  • and Novell ends up with the power to block or license the technique of DRM to anybody it sees fit

    Why exactly are we convinced that Novell will just bury the technique and shield us from DRM forever?

    Novell is a publicly owned company and has a duty (legally) to earn money for their shareholders. I cannot see of a situation where they'd make more by sitting on it, than they would by licensing it - If I was a shareholder in a company that got this patent, I'd want them to make me money.

    The current attack vectors on cryptographic based "DRM" schemes are (1) accidental key leakage, (2) the key exchange system or (3) the fact that the data must be eventually decoded.

    Note that (3) is what makes DRM systems very dumb. It also follows that the Operating System must get involved in order to so hide the data.

    If the Operating System allows a debugger to run AT THE SAME TIME as the "DRM", its attackable. If the OS allows "unsigned" drivers to run, its attackable.

    The OS (for example, Vista) will (eventually) not allow unsigned drivers. It must also "kick out" or "suspend" all non-DRM (unsigned) software when DRM content is played.

    This behaviour falls into Mr. Coxs patent.

    Now, if (Vista) doesn't implement the scheme, it remains vulnerable. So, the problem must be solved another way.

    My suggestion then is to ALSO patent (or disallow) by widely publishing the idea that a hypervisor (VM supervisor) can be used for DRM control as well, and can also be used to suspend, terminate or otherwise control applications that could be used to attack DRM software.

    Got that? It's now published.
  • What no one gets is that DRM is a big compromise. Like all security its a balance between keeping things usable and keeping the media suppliers and the customers happy.

    In a commercial world commercial companies have no requirement to sell anything to any one. So if you say I'll not buy it because it has X or does Y then that's your prerogative. It's the company's prerogative not to sell you something. It is the company's commercial decision to decide how many sales they are happy to lose that way.

    It's an obviously frequent /. misconception that disclosing prior art invalidates a patent/application. The fact is that a similar prior art search and disclosure is a necessary part of the patent search and application process. It proves that one has done one's homework. What needs to be shown is that the patent applied for differs from prior art in a *significant enough* way as to validate the request. Discovery and disclosure by another party of prior art not covered in the disclosure AND of a nature that shows that the request is not unique enough to merit a patent CAN and SHOULD invalidate the request, but this is not always the case.

    The Inventor's Handbook (http://web.mit.edu/invent/h-main.html) describes this and many other relevant points in a manner far more readable than the patent laws.
