    You just had to order them from Europe. Kind of a pain, but they're quality routers. Hopefully at the end of this trial we wont have to circumvent the system though in order to get our "grubby hands" on some quality, dd-wrt running hardware.

        Just because you decide to upgrade the firmware to DD-WRT does not mean that the hardware you run it on isn't important. Personally, I purchased a WRT54G-TM (as opposed to attempting to get a specific version of another model) because I know it has 32M ram and 8M flash, so that I could use the mega image. Ignoring ram/flash sizes, there are still other factors related to the hardware that can affect someone's choice of router. I'm not saying Buffalo is anything special, I don't know; I've never used them

      High quality and high power. the HP versions go up to 350mw easily.

      they kick the crap out of the other ones out there. Except for the new linksys 600N that's my new darling with fast processor, gobs of flash and ram and takes to DD-WRT quite nicely....

    • I have never tried the Buffalo brand, so I may be speaking from ignorance, but my experience is that cheap and quality are mutually exclusive. I recently bought the DGL-4100 for $109, and it is the only router I have EVER owned that has not crapped out and/or required daily reboots in 6 months or less.

    The Federal Circuit only reversed summary judgment as to obviousness of CSIRO's patents. This means that Buffalo Tech. will have a chance to make its case on that issue alone. You see, based on the silence of the BT press release on the other issues against BT on summary judgment, I would have to conclude that the Federal Circuit upheld those.

    I also have to add that the lawsuit is filed in the plaintiff-friendly (to put it softly) E.D. Texas.

      You're right. This was hardly a big victory for Buffalo:

      On appeal, we affirm the district court's summary judgment rulings in all but one respect. With respect to the issue of validity, we uphold the court's entry of summary judgment that the '069 patent was not anticipated. We also uphold the district court's entry of summary judgment that the '069 patent was not invalid because of the addition of new matter to the application or because the asserted claims lacked a sufficient written description in the original specification. With respect to the issue of obviousness, however, we conclude that the district court erred by entering summary judgment against Buffalo because we hold that there was a disputed issue of material fact as to whether the prior art references that were before the district court were combinable in a manner that would have rendered the asserted claims of the '069 patent obvious. Although we vacate the summary judgment of obviousness, we have nonetheless addressed the issue of infringement, on which the district court entered summary judgment against Buffalo, because that issue will continue to be important to the ultimate disposition of the case unless the claims are held to be invalid for obviousness. As to that issue, we uphold the district court's summary judgment of infringement.

      The district court found (on summary judgment) that the patent was not anticipated, valid, not obvious, and infringed. Even for the E.D. Tex., that's a lot to hold on summary judgment, and usually indicates it's a pretty blatant case. The Fed. Cir. upheld all of those findings except obviousness. It did not hold (contrary to the summary) that the patent was invalid. It held that there was an issue of material fact as to obviousness that the district court would need to try to a fact finder. If the district court finds, on remand, that the patent is non-obvious, then Buffalo loses.

      I know there's a huge anti-patent sentiment around here, but patents are my bread and butter, and I tend to believe that there are such things as valid patents. I haven't looked at this patent specifically, but if somebody has a slam dunk argument for why the specific claims at issue are obvious, I'd honestly be interested to hear it. I hate obvious patent too---probably more than you, because I have to litigate against them, fighting the presumption that they're valid with lots of money on the line. But this sounds more like a case where a lot of people are upset that they couldn't get something they liked because it infringed a possibly-valid patent. That is really just the price we pay to have patents at all. Some of the people here will disagree with the whole concept(many will accompany their disagreement with vitriol and poor grammar). But I don't think that a trade secret-only world would be any better.

      So somebody tell me, what is obvious about this patent? I'd be interested to know.

        I just happened to be involved [jwdalton.com] in the university project that produced this patent. The patent was filed before I got involved, so I can't comment on the perceived obviousness at the time of filing (or any other aspect of the filing). From personal experience, in 1995 most people I spoke to about what I was doing didn't "get" it and questioned why anyone would bother doing such a thing. It's hard to tell how much of that was due to the technology being non-obvious, or how much was due to applications being non-obvious.

        It's interesting that there is only one name in common between the list of authors on the patent [uspto.gov] and the paper [sss-mag.com], and that person isn't the lead author on the paper. I guess that might be because the paper is about the second implementation. The first implementation, on which the patent is presumably based, was done in software in non-real time (burst mode). If judging obviousness, it would be worth comparing with the HiperLAN [wikipedia.org] project and the work that went into it.

            Exactly. I believe it should be a presumption. That alone could save millions in litigation costs.

            Most countries have an "absolute novelty" requirement. If you disclose your patent publicly before you file, you can't get a patent. The U.S. has a one-year "grace period," which I think is pretty reasonable. And most patents get published 18 months after their earliest filing date.

            I'm talking about after the fact. If you know I'm working on the same thing you are, it's not fair if you are allowed to mail me a copy of your notebook on your way to the patent office in order to destroy my independent inventor status.

            I haven't looked at this case in detail, but my guess is that it's more than a "passing resemblance." The court found infringement on summary judgment, and the Fed. Cir. upheld it. That has to be a pretty compelling case for infringement. If somebody infringes your valid and enforceable patent, you're entitled to legal relief, even if the other guy worked really hard.

      Well, for whatever it's worth, I've installed a LOT of wireless routers for people over the years - and I learned to generally AVOID Belkin.

      If you've got one that's working well for you, great. But on the whole, they were known for having sub-standard firmware in their devices. I remember, for example, when 802.11g was the "latest and greatest thing", Belkin had a "g" capable router that had a major bug in the firmware, preventing any "g" devices from connecting to it if it was configured to also allow backwards compatibility with "b" devices.

      They did release a firmware update to correct that, but you still had a relatively weak/limited set of configuration options in the product.

      I also recall finding Belkin wi-fi routers to have worse-than-average range.

      People seemed to generally like Buffalo because they were priced a little bit lower than the competition, especially on things like wireless access points (which seem to generally be a big ripoff to this day, since they cost 2x to 3x more than a full-blown router, which can be programmed to function as an access point anyway!). That and they gave good performance for the money, and had better than average web-based interfaces.

    Plaintiffs are using the stupid theory that the 802.11 standard infringes the patents therefore Netgear's products also infringe. The plaintiffs have accused more than 100 Netgear products.

    Netgear is the sole defendant in the case. Some details from Netgear's SEC filing [secinfo.com]:

    In December 2007, a lawsuit was filed against the Company by Fujitsu Limited, LG Electronics, Inc. and U.S. Philips Corporation in the U.S. District Court, Central District of Wisconsin. The plaintiffs allege that the Company infringes U.S. Patent Nos. 6,018,642, 6,469,993 and 4,975,952. The plaintiffs accuse the Companyâ(TM)s wireless networking products compliant with the IEEE 802.11 standards of infringement. The Company filed its answer in the first quarter of 2008. This action is in the discovery phase. The District Court has scheduled an August 15, 2008 claim construction hearing and an April 27, 2009 jury trial.

      I've been reading this court document [uscourts.gov] describing the recent decision this evening. IANAL, but it seems Buffalo has presented entirely reasonable and valid evidence for prior art. Additionally, CSIRO's '069 patent as originally filed specified the 10 GHz frequency range while 802.11 A/B/G/N transmissions occur in the 2.5 and 5 GHz ranges. It seems CSIRO in 1995 amended/revised their patent to remove the very specific 10 GHz reference and instead cited the more general term 'radio frequencies'. They also added new claims specifically cited in the Buffalo case. I've only read the first 25 of 40 pages, but IMHO Buffalo has presented a strong case to be reviewed more carefully than any summary judgment ever oculd. In other words, it's not so much "they aren't paying the inventors for their work" or stealing Intellectual Property. It's more like, "Buffalo presented a case the court summarily ruled against, and CSIRO is trying to enforce a possibly invalid patent." Read the document, and make your own decision. Then come back and post some more.
      • In addition, CSIRO sued buffalo in several other countries over the respective patents, and lost all of these cases(including CSIRO's home country of Australia). This is the reason you can still import Buffalo routers from Japan and Europe.

        My biggest beef is that these suits were leveraged at Buffalo, instead of the chipset manufacturers (Broadcom, Ralink, Texas Instruments, etc). If anyone truly is voilating the patents, it would be the chip providers, not the companies using the chips.

            I thought Buffalo Technology did develop and sell the affected 802.11a chipset.
            Your right in that CSIRO launched injunctions international, but was only successful in the US.

            On a side note: The research done by the CSIRO was done at Macquarie University, which currently has active 802.11a buffalo chip wifi (comp.sci/stat/econ buildings).

            • I was under the impression that the lawsuit was over any wireless product, not just 802.11A products. However, if only 802.11A chipsets were affected, how could the injunction ban them from selling ALL wireless devices in the US?

              Plus, if Buffalo did develop its own 802.11a chipset, I don't believe it was ever imported to the US (ever looked at a Buffalo Japan catalog? there are tons of products not brought to Europe or US). I've worked with quite a few Buffalo products, and the only 802.11a products I recal

  • I never understood the fascination with the Buffalo routers. When I lived in Austin, I just wrote it off as people trying to push the local company on everyone. My experience with their routers is that they were cheap knock-offs of Netgear's low-end wireless routers. And like a lot of the low-end Netgear routers, they had limited range, and would drop connections about every 15 minutes. Have they improved over the years? I would hope so, but my personal experience is to never recommend anyone to buy Buf

      I was going to buy their dual band n router before the injunction hit because it was one of only 2 dual band Ns available at the time, and the specs were impressive.

    • I've had one of the Buffalo routers for around 2 years now (the WHR-G54S), and have never had any significant problems with it - works fine for daily use hooked up to 2 PCs, a laptop, a Wii, and a DS.

      The Linksys router I had before that turned into an unreliable piece of junk about 6 months after purchase - all the problems you apparently had with the Buffalo.

  • I've wondered this since Buffalo routers disappeared from store shelves due to the lawsuit. Are Buffalo routers somehow more infringing on this patent (valid or not) than the million other brands of wifi gear on the store shelves? Since they are all based on the same standards, it would seem like they should all be infringing as well and should be sued also (or at least supporting Buffalo in the fight).

    Have the other companies signed their own licenses or is CSIRO just targeting Buffalo to set a precedent

How many Unix hacks does it take to change a light bulb? Let's see, can you use a shell script for that or does it need a C program?
