Engineer Loses SSL Patent Case against RSA and VeriSign 152

MeanMF writes "eWeek reports that a jury has ruled in favor of the defendants in a patent infringement lawsuit brought by an electrical engineer who clamed rights to a technology used in the SSL protocol. Not only did he lose the case, but next week the jury will rule on whether his patents are valid at all."

    From the site:

    -----

    Stambler filed his suit in February 2001 in U.S. District Court for the District of Delaware in Wilmington. RSA and VeriSign were not the only defendants; Stambler also sued Openwave Systems Inc., First Data Corp, Omnisky Corp., and later, Certicom Corp. Omnisky later went bankrupt, and the three other companies each settled with Stambler.

    Looks like some random "genius" decided he'd make a quick buck on old technology. I'm so sick of this behavior. Anyone remember the Pocket PC fiasco? The guy claimed that MS infringed on his "Pocket PC" which was just a casino style chip that you flip to make decisions.

      I'd almost argue that it causes innovation, though. Fraufenhauer owns MP3. Well, that spurred the creation of OGG, which is pretty superior and free to use, for all. GIF possibly patented? Well, now we have .png, which is also a superior format. I don't think you can patent obvious ideas like "mobile PCs" anyway. It's hard to prove there isn't prior art out there somewhere, not to mention the stupidity involved with, "My casino chip was a POCKET PC!"

        It's not superior if nobody can view it. Among popular web browsers [libpng.org], only KHTML-based (Konqueror; Safari) and Gecko-based (Mozilla; Netscape) browsers can display the MNG format. The most popular web browser [microsoft.com] supports GIF animations but not PNG animations [libpng.org] out of the box. Thus, to reach the largest audiences, web sites will still serve animated advertisement banners as GIF instead of MNG.

        FYI, you don't need to prove that there isn't prior art out there to get a patent, it's the defendant accused of infringing on the patent that must prove the existence of prior art to get off the hook. This is one of the things that is totally backwards with the patent system, it's the accused one who has to prove his innocence, making it belong more in the dark ages than an enlightened society.

      Stambler filed his suit in February 2001 in U.S. District Court for the District of Delaware in Wilmington.

      The big question is, when will Delaware clean up its act? Not content to merely keep quiet and maintain a not-unprofitible existence as screen door manufacturer [superiorscreen.com] for the world, Delaware has lately been attempting to hijack the limelight for itself in a series of staged "coincidences" which I believe are too well-planned to have been anything but a massive attempt to gain prestige amongst the other 49 states. Consider, if you will:

      Engineer has "patents" which would invalidate the security of the Internet. Where does he go? Delaware.

      Marvel Comics, home of Spider-Man, the X-Men, and many other lovable good guys, files for bankruptcy [lubbockonline.com]. Where are they forced to do it? Delaware.

      The movie Fight Club. Where's it take place? Delaware.

      In an episode of the Cosby Show, Vanessa's car is stolen. In Delaware.

      Look, I'm a pretty average guy, not some conspiracy nut. But the evidence speaks for itself: Delaware wants to rule the world. And something must be done. Thank you.

Usually, it's some clerk who wouldn't know a patent if they infringed upon one who says, "that's nice", but on occasion a more senior B&N staffer has asked me to elaborate and take note of my input.

      Do my lowly few hundred dollars of purchases a year make that much of a difference in B&N's policy? Not bloody likely. But, it costs me nothing to make my position clear, and there is always the slightest chance it might get others (store personel, managers, other customers) to pause and think.

    I was always under the impression that patents cannot be inforced if the holder sits back and allows their technology to be used and adopted, only to decide that they want royalties years later, when people have come to rely on it.

    This, I thought was illegal. Owners of patents have an obligation to tell people that they are using licensed technology, and that they have a right to charge a fee.

      You have to defend trademarks, not patents or copyrights. You can sit and let a patent stagnate for 10 years and then sue the balls off everyone later. The justification? They should have done their market research.

      Look at Intergraph... CNet news claims (got this from the last posting [com.com] about SCO vs. IBM): "In 2002, Intergraph's income from operations was $10 million, but its net income including legal settlements was $378 million."

      Nasty stuff. Anyways, IIRC, Intergraph sued Intel and some other companies because of some kind of architecture design the Pentium used, specifically the system bus. Not sure if that's accurate, but try here [com.com] and here [com.com].

        You have to defend trademarks, not patents or copyrights. You can sit and let a patent stagnate for 10 years and then sue the balls off everyone later.

        If an alleged infringer convinces a U.S. court that a patent holder has harmed competitors by delaying legal action relating to a patent, the court may impose "laches" on him. Laches would mean that he cannot collect damages for infringements that had occurred before the patent holder brought legal action. Precedent states that a delay of at least six years is presumed harmful to competitors.

        • OK, so I guess Intergraph missed the mark... I believe they had patents on their Clipper chip from no later than 1993... so the Pentium came out when?... I can't remember, 1995 maybe?... Intergraph filed suit in 1997, which is only two years. Still, there's something to be said about 97% of your net profit coming from lawsuits :).
          • Oh wait, I was wrong. That 1997 filing was in a previous case with which Intel settled. Intergraph then sued a bunch of PC makers in 2002, and I'm assuming the alleged infringement would have been for no later than 1996... so 6 years between the initial infringement and the filing of the suit.

      Then you thought incorrectly. Trademarks are subject to such a required defense, but patents and copyrights are not.

      There is the doctrine of laches [converium.com], which allow a judge to hold that a patent holder, having allowed a use of their patent to go on without notice, cannot collect damages for use of their patent prior to filing suit, but this in no way invalidates their patent nor does it prevent them from collecting damages if the same defendant should happen to infringe on their patent in the future. (Laches is basically a way of wedging the reasonable "but I didn't know it was a problem" defense into patent law)

      And no, IANAL, but I do know how to use Google [google.com] (TM).

  • Did he come up with a similiar method, and then years later when another company comes out with a piece of software that does the same thing a bit differently, he goes bonkers?

If the lawyers give a number larger than $50k, then they "lose the bid" and the company settles instead of fighting.

        Nonetheless, I still think we should really examine just what 'intellectual property' really is.

        A patent needs 3 things to qualify. (1) novelty -- it is new and novel, (2) non-obviousness, it is not some idea that anyone would have thought of such as 1 click shopping, (3) I have forgotten the third requirement. Rigtht now an idea no matter how stupid can get patented in spite of the requirements. Maybe a requirement should be added that the idea is NOT a trivial improvement to something already existing.

        The analogy to land ownership is a good one. The basic problem with the patent system today is similar to that of a dysfunctional system of land tenure.

        In imperfectly-settled systems of land tenure, people will invest substantial amounts of time and money into improving a tract of land, only to have the fruits of their labors taken by previously unknown (and sometimes unknowable) claimants to ownership of the land. This is quite unfair, and acts as a disincentive to progress.

        Similarly, the granting of patents on obvious and non-novel 'inventions', and the prevalence of 'submarine' patents (patents granted after years of secrecy) all tend to retard progress by instilling the fear that some patentee will pop out of nowhere and steal the rewards due to real innovators, as opposed to those skilled in paper shuffling.

        In essence, the opposition to bogus patents is an affirmation of property rights. The worker should enjoy the fruits of his labor, and not have it stolen from him by the arcane processes of a fusty, hidebound bureaucracy.
      • Only one person can use the same plot of meat-space , or physical universe. So it is easily defensible that propriety should exist on the physical side. Actually everything in our society is absed on this concept of physical appropriation.

        Now for idea this is dfar more complicated. Many person can posses the same idea, the first person to come with do not loose the idea. it isn't like a physical object, inmformation and idea can be copied at will. Now where the problem comes is that since 100,150 years to ensure developpement and research the various govt saw fit to give a small advantage to the discoverer. And one can argue that this small advantage was enough, but by lobbying and pressuring the industry wants to transform this advantage into a incredible pressure and monopolysation machine. Therein lies the problem with all the IP stuff, what people contest : It should be a balance but it ceased recently to be.

        Nevertheless to comes back to your post, NO IP is not like meatspace. Truth cannot be owned for the simple reason that as soon as you spread it you share its apropriation. The only way to "protect" truth and really own it in the litteral science is either 1) abvoid saying it (protection by secrecy) 2) introduce artigfical barrier to spreading like IP law. But both are not natural for social animals like human.

Most importantly, what makes you think he did not do anything with those patents or even needed to?

      You don't need to do anything other than put a good faith effort. I could have an idea that would take billions of dollars to implement, it's still mine and the patent office would still grant me protection of that idea for being good enough to share it through them.

      Oh yeah, that'd be a great system.

      So If some genius inventor invents some process for making a new gee-whiz alloy/ceramic/whatever which would say increase the safety while also decreasing weight and production costs of cars significantly - enough to say save car companies a few billion dollars a year. However, in order to move the thing off the lab top and into real production would require a few billion dollars of investment and would also infringe on a few patents held by car manufacturers.

      Would the car companies:

      A. Buy the rights to the patent for *lots* of money and make the stuff?

      B. License their patents to someone (say the inventor) or some company who will make the stuff?

      C. Do nothing for 2 years, and have the patent invalidated thus saving *lots* of money and making the stuff themselves a bit later?

      • To follow your analogy, my thoughts on the subject would be that the inventor trying to market her invention or license her invention would be more than enough to validate her claim to the patent.

        Rather than waste our collective energies decrying the victims of a broken patent system, we should fix and refine the process by which patentees are recognized.

  • First off, you may not realize just how ubiquitous SSL really is. It's easy to confuse it with other new security technologies, such as SSH. Here's a big reason the guy is suing -- he wants kickbacks from IE, Mozilla, Netscape -- which means RSA and VeriSign since they're getting sent the bill payments from the client software makers.
    SSL support is included in every Web browser on the market and is used to encrypt sensitive traffic to ensure the confidentiality and integrity of the message. RSA and VeriSign, as well as the other original defendants, sell products that utilize SSL.
    That's a huge piece of the security pie so to speak, and I can see how he's interested. Even though he may be wrong about his claim. Make sure you read all the way down though.
    The case isn't over yet, however. The jury next week will begin hearing testimony on a separate phase of the suit, which will determine whether Stambler's patents are even valid.

    • Sorry, no. You can't get sued for a program like that, the patent in question [uspto.gov] has expired.

      Moreover, the expired patent does not cover just XOR, it covers a system of which XOR is a part. Such a system as a whole was probably pretty novel in 1978. (Yes, software patents were perhaps too long given the pace of innovation at that time.)

      • I agree.. I didn't read the whole patent.. but using XOR to highlight the position of a mouse sounds novel to me (IF it hasn't been done in 1980)... it doesn't matter if its 3 lines or 3million lines of code. XOR itself is probably not patentable. Its like you cannot patent a simple fan nor a plain cap, but put them together and you've got a patentable product! (Yes yes, someone already patented it and the patent has already expired).

          1. Background redraw

          In this case, the background is redrawn at each frame and all sprites are drawn over it.

          1.1. Partial redraw

          Same as 1. but the only areas redrawn are those that where written over via

          2. Reversible operations

          2.1. XOR.

          XOR a shape, reverse the operation by XORing it.

          2.2. Buffers.

          Copy the area that you are writing to into a buffer. Write. Reverse the operation by copying the buffer back. Note that this is different from 1.1, since *each and every* opearation is reversible. In 1.1. you go back to a 'blank' state by redrawing. Also, for a large number of shapes methods 1. and 1.1. can be much faster than reversible operations.


  • ...and the three other companies each settled with Stambler.

    Should Mr. Stabler reimburse the companies that settled? Does anything say he has to? WIll they come after him for the money? Just a thought.
    • At least in Netherlands, invalidation of a patent has no retro-active effect on license agreements. Sounds reasonable to me: if I would take a license (or a more practical case: negotiate a license for a client of mine), I would check validity of the patent first. When the companies signing the license agreement have not done so: sue your attorney. He should have giving you that advice. And when the attorney has given that advice, but the companies thought the search would be too expensive, so they skipped it: quite stupid.

      Perhaps 35 USC or 37 CFR has a similar clause. I am no US legal expert, so I don't know.

  • "Not only did he lose the case, but next week the jury will rule on whether his patents are valid at all."

    So why don't we employ a similar method before a patent is awarded?

    Think of all the frivolous lawsuits that would be prevented, as well as the absolutely absurd attempts to patent breathing, etc...
    • The point is, the USPTO probably allocated ONE person to research the prior art before granting the patent... there's no way that person could have uncovered everything out there.

      When RSA and Netscape decided to challenge the patent, they probably spent millions to uncover prior art that would NOW make the patent invalid.

      Its not that straightforward.
  • I could make some enlightened post that dazzles all who read it with its genius, but I won't. Instead I'll quote the character Dick from Shakespeare's Henry VI, part 2.

    The first thing we do, let's kill all the lawyers.
    • Congratulations! You are the 1 BILLIONTH person to misquote Shakespeare! When looked at in context, this quote actually PROVES THE NECESSITY of lawyers in civilization. The characters were trying to create anarchy - killing the lawyers would remove the rule of law and cause just that.

        • Bah. I hate being wrong. Even more, I hate not remembering enough Shakespeare to be able to evaluate whether the web site you linked to is full of it or not. If I had more time I'd dig deeper - or I'd just chalk this one up and play my guitar.

    A very interesting (and insightful) account of the first two days of the trial can be found here [ieee.org]

    Not only did the other parties settle, they settled for huge amounts of money. First Data settled [nytimes.com] for $4 million. This, of course is on top of nearly a million dollars in other settlements from other victims, and on top of a $2.6 million settlement for Stambler's previous bogus patent. A nice way to make $7.5 million.
  • Of course his patents are bogus and lack novelty (here [uspto.gov]), but they don't seem any more bogus than a lot of other stuff that gets patented. In particular, his more recent patents look like the obvious application of an old idea to specific areas, but as defenders of the patent system are often so fond of saying "well, the underlying algorithm/gadget/... may be known, but patents are for useful ways of solving real problems, and this particular solution hasn't been patented before, so it must be novel, right?"

    The sad thing is that if these patents had been held by a laywer or a big company with a good legal team, they probably would have held up at least long enough for them to generate some revenue. And chances are they would have picked their legal battles more carefully and settled out of court at just the right points to avoid even the risk of invalidation.

    A transaction system is disclosed wherein, when a transaction, document or thing needs to be authenticated, information associated with one or more of the parties involved is coded together to produce a joint code. This joint code is then utilized to code information relevant to the transaction, document or record, in order to produce a variable authentication number (VAN) at the initiation of the transaction. This VAN is thereafter associated with the transaction and is recorded on the document or thing, along with the original information that was coded. During subsequent stages of the transaction, only parties capable of reconstructing the joint code will be able to uncode the VAN properly in order to re-derive the information. The joint code serves to authenticate the parties, and the comparison of the re-derived information against the information recorded on the document serves to authenticate the accuracy of that information.

    I'm not a lawyer, and I'm not an expert on encryption, but this doesn't sound like a bs patent to me. is it possible that a legitimate inventor got screwed trying to press his claim on a corportation that just doesn't want to pay people for what they've rightfully created?
    • Patents are supposed to be non-obvious to experts in the field. There is nothing novel or non-obvious about this one. Anybody who seriously studies encryption would have known about this technique years ago. Surely there are academic papers out there describing this, which pre-date this 1999 patent. This is very similar to storing encrypted information using a customer's password as part of the key, so the entire key does not have to be stored on the server.
    • What the patent describes is the use of a public-key cryptosystem to sign a document. That was well-known a decade before the patent was applied for. His patent fails both on obviousness and originality.

  • During my professional education, a teacher (head of IP department multinational industry firm) taught me that in 67% of the invalidity cases without jury, the patent would stand and that with a jury, in 75% of the cases, the patent would hold (in US that is, you cannot imagine how happy I am with a legal system without juries but with professional judges).

    Is it safe to draw a preliminary conclusion here that these patents of Stambler are really crappy?
