CSIRO Wireless Patent Reaffirmed In US Court 147

An anonymous reader writes ""The CSIRO has won a landmark US legal battle against Buffalo Technology, under which it could receive royalties from every producer of wireless local area network (WLAN) products worldwide." From the article: "The patent, granted to CSIRO in 1996, encompasses elements of the 802.11a/g wireless technology that is now an industry standard. It stems from a system developed by CSIRO in the early '90s, 'to exchange large amounts of information wirelessly at high speed, within environments such as offices and homes,' said a CSIRO spokeswoman."

        why would those utilizing the technology be sued?

        Because rightly or wrongly, a patent grants exclusive rights to make, sell or use an invention. The end users are infringing on the patent by using the technology, and unless they got explicit indemnification from the manufacturer, they can be sued.

        The main reason that they probably won't get sued is because it's simply easier to extract a lot of money from a few manufacturers than tiny amounts of money from each of millions of users.

          Well, technically, a patent gives you the exclusive right to stop others from practicing the invention.

          It's not just a semantic quibble I'm making here, the difference is that the patent holder has to actively enforce their patent, and typically that is not an economically feasible thing to do against infringers who don't have deep pockets.

          There's money in manufacturers because presumably they want to continue marketing their products, but wouldn't the only thing a manufacturer could possibly do to a person by suing them is force people to stop using said products?

      • As soon as the manufacturers go bankrupt from the suits the cities become liable if they don't take down all their equipment. Otherwise, tiny shell companies could email out a bunch of copies of say freetype binaries with the patented hinting code turned on, get sued into bankruptcy, and then everyone who downloaded the binaries would be scot free. It doesn't work that way.

      As an ex-CSIRO scientist from the early 1990's who personally developed several diagnostic assays for chlamydia trachomatis (look it up) which were commissioned by a certain large Swedish pharmaceutical company, I can confidently say, that the work done wasn't solely for the benefit of Australian companies.

      For some years, the CSIRO has had a policy of being a hired gun, so to speak, for anyone prepared to hand over the readies, and further, applies pressure to the various divisions, to be self-funding to a certain degree (in my particular group, it was 30% but that was 12 years ago now).

      The current Australian goverment, is, unfortunately, a conservative one, and is only too happy to put pressure on the CSIRO and other research institutes to get their funding from elsewhere, rather than from the public purse (well, gives them more money to piss up against the wall for defence et cetera).

      10 years, however, is about par for the course with anything at the CSIRO, as it is now top heavy with administrators whose sole aim in life is to ensure that their arses are protected. The truly great and good scientists from there have all buggered orf or taken their generous redundany pay and retired. Me? I was headhunted over 10 years ago and I don't really miss it the way it is now.

      Thanks for the links. My fear initially was that this was just another craptastic submarine patent.

      But here's a question. 802.11a has been a standard a long time, in development long before its acceptance. Why is it that the patents that apply to the technology that this standard is based off just NOW coming to light? Why were patent/royalty issue not brought up in 1999 or earlier?

      It seems kind of shady to me to wait until after the standard was released (1999), after wide spread US adoption (2001), after world wide adoption (2003), until years later when the technology is so prolific that companies that have based their entire success on the technologies covered by the patents have no option to change to a non-infringing technology. Or has this been a 7+ year long court case?

      That is not what happened in this case. The patent holder was "holding back" in this case because they had no option. It was an Australian patent against a US corporation. Now that the FTA is in force, this has opened the opportunity not only for the Australian patent holder to enforce their patent in the US, but also for the US corporation to challenge the Australian patent in court. Guess what? The greedy US corportation challenged the CSIRO, an honorable scientific research entity, in court to have their patent invalidated. So naturally, as is required to retain a patent, the CSIRO had to defend their patent to keep it.

      The CSIRO [] are good people. They do lots of good things [] for the good of not just Australia, but the World.

      This court case was brought against them, the CSIRO, in an attempt to invalidate their rightful patent. If you do not defend your patent, you lose it.

      So here we have a case where a money motivated corporation is trying to stomp on a scientific research entity (which only strives to further the state of the art), so that the corportation can make more money. Thankfully the scientific research entity came out on top.

    • Just because a company is ready to patent something doesn't mean they're ready to produce something right away. Reducing the amount of time a patent is good for reduces the value so companies won't bother with R&D nearly as much. Patents need to be given out on a stricter basis.

    Although this is certainly a big victory for CSIRO, the battle over this patent is far from over. Almost all "big" patent suits are appealed to the Court of Appeals for the Federal Circuit, which is the appellate court that has jurisdiction over patent appeals. The Federal Circuit reverses district court decisions (like the decision mentioned in the story) about 60% of the time. It also takes several years to move through the appellate process, which means it will be quite some time before Buffalo pays a cent to CSIRO.
