        Yes. We are starting the age of Corporate Law. You will now have three types of offenses. Criminal, Civil, and unofficial Corporate (being a subset of Civil but controlled by money).

        To be found guilty of a Corporate Offense, you only need to have too little money to defend yourself against a corporation than has alot of money. The actual offense is irrelevant. The punishment is relative to the pre-determined settlement contract with the corporation or the civil law of choice.

        Don't believe in Corporate Offenses? How do you justify some of the actions of the RIAA, MPAA, and SCO? Some are valid, some are made up. Some people settle when they are innocent because it is cheaper than the legal fees required to defend yourself. Others fight, win, and still lose money. To be guilty of a Corporate Offense does not require a judge. It requires only getting the attention of a corporation's legal department.
    • If the patent is based on one or more in-process IETF standards, then the short answer is "no way". There's no way they'd even grant their patents let alone let them enforce them.

        They were granted the patent, but it won't be enforceable because microsoft didn't disclose the prior art. What is particularly embarrassing and points to the fraudulence of MS is that the people who's names where on the patent were also on the IPv6 committee.

        There should be a very stiff penalty for knowingly filing a fraudulent patent application. Both monetary, and being prohibited from filing for any other patents for a period of time sounds about right.

      When people get involved in developing a spec, and at the same time patent things that are necessary to implement that spec ("essential", as the patent lawyers say), and then submerge, wait until the spec is widely adopted, and then announce their patent, this is sometimes called a submarine patent attack.

      It's partly to prevent these that we (W3C [w3.org]) have our patent policy, which requires all participants to sign an agreement saying (more or less) they agree to let people implement the spec without paying royalties, even if they own patents that would otherwise apply.

      It's all a big mess -- and patents also don't fit well with the GPL, of course, and neither does our patent policy, although FSF participated and we did the best we could: the problem is that you might want to take, say, an HTTP server, and re-use the network code for some other server. But if someone has a patent on servers, to which they have granted royalty free use for HTTP only, you may now have to pay them a royalty for the code.

      Patents are intended to encourage innovation by ensuring inventors get royalties. Unfortunately the current system seems to have some disadvantages.

      Note: I have no idea whether the slashdot story is correct in this instance about this patent, nor, if the patent is essential to implementing IPv6, whether Microsoft plans to enforce royalties or forbid implementations.

        I'm literally sick from this one. I was at the IPv6 summit in 1998 and 1999. I talked with Microsoft's people, who were apologetic for having such poor implimentation in their IP stack for IPv6. They explained that while Microsoft Research folks were believers in IPv6, Microsoft proper didn't think it had many merits and refused to back it. Their stack crashed repeatedly (while Linux, Cisco and BSD folks had no problems playing well on the IPv6 network operational at the summits).

        And now these followers are taking credit for the work of countless great people? Pretending to have actually invented it all? WTF???

        I'm going to rip out Microsoft servers at work and treat them for what they are: intellectual property parasites. Nothing but thieves. I've laughed at the "worlds best marketers of mediocre software" jokes, but now it's personal. Those jokers admitted they were behind in 98-99. At Telluride in 99, they were embarrassed at how far behind Microsoft was in the protocol.

        If you work for Microsoft, pay attention! Your company increasingly comes acrossed as nothing but a poseur in the technology community. Many of us have put up with MCSE pretenders. But now it's personal. Hang your head low, Microsoft grunt. Your credentials are a black mark in these circles.

        • Those jokers admitted they were behind in 98-99

          They're still behind now - none of the standard windows services support v6 yet and there appears to be no way (under XPSP2) of manually configuring the IP address.

          Compared to my Linux boxes, which have all but a few stubborn services running on IPv6. (I currently have to use v4 for Asterisk, Portmap and CUPS... which is stunningly bad given that CUPS is a new system but doesn't do IPv6 at all.)

      The patent system needs to be completely overhauled. In fact, for the same reason, it appears the US legal system needs an overhaul as well. To bad it is basically impossible. Here is the problem:

      In patent law, all you need is the ability to claim infringement (hell, you can use a completely unrelated patent if you have a weaker opponent). Once you can get your toe in the door with the courts, it becomes about money. The more money you spend on lawyers, the longer the case will drag on and the more it will cost your opponent to defend himself (or in the case of a real patent lawsuit against a rich corporation, the more it will cost your opponent to prove his claim).

      Because most individuals and corporations cannot tolerate the massive legal bill of a head-on IP conflict with a rich opponent, in the majority of cases, the weaker opponent must settle. The result? It makes no difference who is right, it only matters who is willing to spend more.

      Today, it has become like that in practically every segment of the American legal system. This is nothing more than glorified corruption and all it does is serve to ensure that the wealthiest individuals and corporations are untouchable. To add insult to injury, it ties up our tax funded court system, so we end up partially financing the corrupt activities of the wealthiest individuals and corporations.

      I don't know how it would be possible, but something is needed to correct this imbalance. There should be SEVERE damage recovery for defendants that are shown to be innocent to account for their time, money and suffering of being dragged through the courts. There should likewise be SEVERE amplification of damages for corporations and individuals that put up massive, expensive legal defenses and are found guilty. Perhaps there should also be some means of capping expenditures on both parties (e.g. Corporation sues individual - legal expense cap for both parties limited to spending power of individual).

      The whole thing sickens me.

    Based upon my cursory reading of the patent, it appears to be just the sort of thing that the EU keeps throwing out, again and again.

    Admittedly in WIPO countries (since the patent is registered in the .us and .us patent law allows these kinds of shenanigans) royalties may have to be paid, but the EU parliament's reasonably clear stance on such things should go a long way towards making sure that this patent is a dead duck in a lot of the civilised world.

    Regardless, this sort of patent tomfoolery should be illegal. WIPO should (although this will never happen) declare a patent unenforcable under the terms of the Berne Convention should said patent have been undisclosed during a supposedly 'open' working group.

      A much closer precedent for this sort of tomfoolery was the IETF's MARID working group.

      For those of you who don't remember, Microsoft allied themselves (and their Sender ID standard) with Meng Weng Wong/PoBox's SPF standard, to create a supposed uber-standard known as 'Caller ID' (SPF v2). Later on, it came to light that MS owned key patents on many of the methodologies which SPF2 and Sender ID used, and their patent license was abhorrent to many of the working group's participants. The IETF then disbanded the working group.

      I'm working from memory, so I don't have much in the way of sources, but googling for "Microsoft MARID" should turn over a few stones.
      • I hate nitpicking my own posts, but I got the names of MS's two standards backwards:

        'Sender ID' was the later, merged-with-SPF standard.
        'Caller ID' was their own, patent-encumbered proposal.

        Sorry. That is all.
        • Their later standard is still patent encumbered. They're also now claiming all the SPF users as SenderID users, which is blatantly false. Looking at the SPF archives, it's fun to watch Meng try and make Microsoft sound like they were ever reasonable. It's like a battered child, making excuses for their molesting parent and pretend that the violations were their own fault while their friends, teachers, and social workers say "report them and get out of that house!"

Especially in litigation, where even if you spend the money on the lawyers, you still may lose anyway. At some point you just make a business decision.

    The patent abstract:
    A method and computer product for automatically generating an IP network address that facilitates simplified network connection and administration for small-scale IP networks without IP address servers, such as those found in a small business or home network environment. First, a proposed IP address is generated by selecting a network identifying portion (sometimes known as an IP network prefix) while deterministically generating the host identifying portion based on information available to the IP host. For example, the IEEE 802 Ethernet address found in the network interface card may be used with a deterministic hashing function to generate the host identifying portion of the IP address. Next, the generated IP address is tested on the network to assure that no existing IP host is using that particular IP address. If the generated IP address already exists, then a new IP address is generated, otherwise, the IP host will use the generated IP address to communicate over the network. While using the generated IP address, if an IP address server subsequently becomes available, the host will conform to IP address server protocols for receiving an assigned IP address and gradually cease using the automatically generated IP address.

    Now that bear pretty much zero similarity to IPv6, which is among others: expanding address space over IPv4 while being somewhat backwards compatible for a transition period, improved IP packet modularity for less overhead, new hierarchical infrastructure for improved routing support, built-in IPSec, improved quality-of-service (QoS) support, improved support for ad hoc networking, and improved support for extensibility.

    That abstract seems to me that this is... well, something entirely different?

    Is it even a protocol?? "A method and computer product for automatically generating an IP network address"... Huh??

      Nope. Read the IPv6 specs.

      IPv6 has an autoconfiguration mechanism whereby an IPv6 autoconfiguration server will spit out a 64-bit prefix (all local networks are /64s in IPv6), and a host will create an EUI-64 address to postpend to it, as a deterministic function of the interface's layer 2 address.

        I had a quick squiz through RFC1883 (http://ietf.org/rfc/rfc1883.txt?number=1883) "Internet Protocol, Version 6 (IPv6) Specification" and all it appears to mention on the subject is:

        "IPv6 increases the IP address size from 32 bits to 128 bits, to support more levels of addressing hierarchy, a much greater number of addressable nodes, and simpler auto-configuration of addresses."

        Going into more detail and reading RFC1971 (http://ietf.org/rfc/rfc1971.txt?number=1971) " IPv6 Stateless Address Autoconfiguration" gives you the nuts and bolts of how it actually happens. Abstract says:

        "This document specifies the steps a host takes in deciding how to autoconfigure its interfaces in IP version 6. The autoconfiguration process includes creating a link-local address and verifying its uniqueness on a link, determining what information should be autoconfigured (addresses, other information, or both), and in the case of addresses, whether they should be obtained through the stateless mechanism, the stateful mechanism, or both. This document defines the process for generating a link-local address, the process for generating site-local and global addresses via stateless address autoconfiguration, and the Duplicate Address Detection procedure. The details of autoconfiguration using the stateful protocol are specified elsewhere."

        Two key points here: 1) Stateful autoconfiguration and 2) Stateless autoconfiguration.

        1) Stateful autoconfiguration: Is where it uses a server. Ignore.

        2) Stateless autoconfiguration: Does NOT require a server, but requires a router if you want more than just a link-local address. From the RFC:

        " IPv6 defines both a stateful and stateless address autoconfiguration mechanism. Stateless autoconfiguration requires no manual configuration of hosts, minimal (if any) configuration of routers, and no additional servers. The stateless mechanism allows a host to generate its own addresses using a combination of locally available information and information advertised by routers. Routers advertise prefixes that identify the subnet(s) associated with a link, while hosts generate an "interface token" that uniquely identifies an interface on a subnet. An address is formed by combining the two. In the absence of routers, a host can only generate link-local addresses. However, link-local addresses are sufficient for allowing communication among nodes attached to the same link."

        For the record, "link local addresses" are defined as:

        "an address having link-only scope that can be used to reach neighboring nodes attached to the same link. All interfaces have a link-local unicast address."

        So, essentially, it looks like MS is getting VERY close to what this RFC states, although they seem to be allowing more than just a link-local address without needing a router.

        Cheers,
        Sampizcat

    • IPv6 has stateless autoconfiguration, where machines are automaticlly given ip addresses. The first 64bit s of the address is the network prefix and the second 64 bits is a padded form of the 48 bit MAC address.

    Abstract: A method and computer product for automatically generating an IP network address that facilitates simplified network connection and administration for small-scale IP networks without IP address servers, such as those found in a small business or home network environment. First, a proposed IP address is generated by selecting a network identifying portion (sometimes known as an IP network prefix) while deterministically generating the host identifying portion based on information available to the IP host. For example, the IEEE 802 Ethernet address found in the network interface card may be used with a deterministic hashing function to generate the host identifying portion of the IP address. Next, the generated IP address is tested on the network to assure that no existing IP host is using that particular IP address. If the generated IP address already exists, then a new IP address is generated, otherwise, the IP host will use the generated IP address to communicate over the network. While using the generated IP address, if an IP address server subsequently becomes available, the host will conform to IP address server protocols for receiving an assigned IP address and gradually cease using the automatically generated IP address.

    Application Number: 57135
    Filing Date: April 8, 1998
    Publication Date: August 8, 2000

    Claims:

    What is claimed and desired to be secured by United States Letters Patent is:

    1. In a host that has been connected to a network that does not have an IP address server and is not connected with any network having an IP address server, a method for automatically generating an IP address for the host, without another component of the network being required to transmit, to the host over the network, an IP address of said other component, the method comprising the steps of:

    without the host having received over the network any IP address of another component of the network, selecting a valid network identifying value as a network identifying portion of the IP address for the host;

    without the host having received over the network said any IP address of another component of the network, generating a host identifying portion of the IP address for the host based on information available to the host;

    and testing the generated IP address for the host for conflicting usage by another host on the network and determining that no conflicting usage of the generated IP address exists.

    2. A method as recited in claim 1, wherein the network identifying portion of the generated IP address is chosen to be 10.

    3. A method as recited in claim 1, further comprising the steps of: determining that an IP address server is not present prior to selecting the network identifying portion of the IP address; and ascertaining if an IP address server later becomes present over the network.

    4. A method as recited in claim 3, further comprising the steps of: assigning an IP address from the IP address server to the host when an IP address server is available over the IP network; and immediately discontinuing use of the generated IP address when an assigned IP address is received from an IP address server available over the network.

    5. A method as recited in claim 3, further comprising the steps of: assigning an address from the IP address server to the host when an IP address server is available over the network; and gradually discontinuing use of the generated IP address when an assigned IP address is received from an IP address server available over the network.

    6. A method as recited in claim 3, further comprising the step of assigning an IP address from the IP address server to the host

    Ok, the article, the pubpat guy, the slashdot editors, everyone's missed the boat on this one.

    While this patent is not quite brilliant, it's not ipv6, this is a patent on the "automatic addressing" function in windows ME, 2k, xp, etc, where if your network card has link, but can't find a dhcp server the system auto-assigns an address from like a 169 or something subnet that MS owns.

    This patent has absolutely nothing to do with ipv6 further, I believe MS was the first to do anything like this, even now they are (unless maybe apple does it now too... but I don't think they do either). Anyway I've never seen the feature actually be useful, mostly it is an annoyance, but it's not ipv6
    • I think this is what you're referring to:

      auto-ip [potaroo.net]

      Automatically assign an address on the 169.254.0.0/16 network if no DHCP server is found. Continue making DHCP requests every 2-4 minutes until DHCP server does respond...

    but upon glancing over the patent, the abstract completely contradicts the complaints that this patent has received.

    It is nothing like IPv6. It sounds like a zero-config DHCP.

    If not for the fact that they lasted so long. Hey, if Microsoft did not patent the internet, then some other company which exists solely for the purpose of extorting money out of other companies with patent lawsuit threats would have done it.

    I myself have been personally involved in the patent process for reasons I can't mention here, but I have learned through it all that more times than not companies such as Microsoft file or acquire patents for defensive reasons much more often than for the purposes of bullying the small guy with threats of litigation.

    I mean, what if Microsoft or Amazon.com didn't file some of these ridiculous patents and somebody else did, then sued Microsoft or Amazon.com or [INSERT GIANT MULTINATIONAL SOFTWARE COMPANY HERE], and this company was able to extort millions, perhaps billions of dollars from these big companies by abusing the patent system. I mean, if you are a patent-squatter what is the point of wasting your time suing a small fry when you can go for the Big Kahuna.

    But the worst thing about all of this is that unless you defend your patent in court, you lose it. So, whether Microsoft or Amazon.com wants to defend their patents or not against a company which may have technology that is related to their patent, they are forced to sue those companies anyways.

    In addition to health care costs for businesses, high corporate taxes, weak anti-trust laws as well as poor enforcement of them, I would say our ass-backwards patent system is one of the major poisons of starting a technology business in the United States these days.

    I am no fan of oursourcing myself, but as a business owner of a software company myself, you sometimes have to ask yourself how the hell are you supposed to compete in the world marketplace when the laws and regulations in your own country AND THE ENFORCEMENT OF THOSE LAWS AND REGULATIONS is rigged entirely in favor of multinational corporations which really don't even have any national loyalty to any particular nation, yet due to the weakness of democratic republics around the world where votes can easily be bought and sold, small business owners in the technology industry either have to play by the rigged rules of the big companies or not play at all.

    Technology patents may seem like a huge problem when it comes to stifling innovation in the United States and around the world, but unfortunately they are just a small problem in a giant sea of problems that exist due to well-intentioned ideas such as patents being corrupted by giant amoral companies and the soulless people who run them.

    1. Sit in on many of the standards committees.
    2. As the committee begins to discuss ideas, patent them behind the scenes
    3. Dont implement standards properly (IE, Office, TransactSQL...), but do implement own proprietary protocols/specs/language correctly.
    4. Scare people away from standards using patents
    5. Profit!
    I mean - these MS guys sat on the standards committee knowing that they had already attempted to patent what the standards committee was discussing. I bet they didn't disclose that to the committee! Dishonest - but brilliant.

    Even for Microsoft, this one reeks.

    Having said that, you can understand why Microsoft are claiming patent territory - they have been smacked [eweek.com] around [eweek.com] pretty [betanews.com] badly [theregister.co.uk]by software patents in the past. I wonder how many other gems are out there waiting to be discovered in amongst the 3000 or so patent apps per year MS puts forward.

    • Further to this...

      Keep in mind that there has already been shown to be *signficant* revenue in licensing patents - its an awesome business model.

      Create the patent (this does involve research and work and inventiveness). Then let other people productise it, take the risk, sell it and pay royalties to you. (Profit!!!)For example: [ffii.org]

      Collecting the patent royalties could add millions to IBM's net profits. In 1995--the last year IBM released figures--the company took in $650 million from royalties on all patents

    The flaws in the software patent system have spawned a whole new kind of patent
    filing; that with which to PROTECT things so that OTHER unscrupulous assholes
    don't patent them instead.

    Imagine if a fairly original idea was had, but it was SO obviously done. Patent
    it. Patent it NOW. Otherwise when someone has the same idea in the same week
    and they patent it, they will f**k you in the ass in 9 years when you finally
    finish your software.

    Case in point;

    Apple, IBM and Motorola have patented many algorithms using AltiVec units in order
    to protect the vector unit from unscrupulous "inventors". If the vectorisation of
    an algorithm is patented by someone else, they may choose to charge extortionate
    fees for the licensing, at which point to effectively use a processor you first
    have to buy it and then pay some unrelated company a fee. This is obviously
    unacceptable.

    IBM and Novell have been doing exactly the same for Linux in the past years too.
    SGI have patented a few things in OpenGL in order to protect the API.

    These uses of software patent law IMPROVE matters, not "kill and inhibit" software
    and progress.

    Microsoft here have basically repatented their own "AutoNet" idea (the use of a certain range of IP addresses to give to network cards if DHCP isn't there, no
    other address protocol can be found, and an ARP check tells it's not already in
    use). It's defined in prior-art style in RFC1971 for IPv6 (1995/1996) so the patent isn't "enforcable" per se by any company (Microsoft couldn't hope to use
    it to extort money).

    This is so obviously a cheap legal protection tactic, which any IP lawyer worth
    is salt would suggest to the engineers defining the standard. Patent it now before
    some prick does it for us.

    After reading TFA I read the actual patent (well, what I could get from the legalese). And, from my (admittedly limited) understanding of IPv6, I couldn't see the issue. So I went to check the fine links in the FA.

    Surprise, the name of the guy that came up with the original complaint sounded familiar.

    So I did a Google on it, and found the article [forbes.com] I remembered (he's mentioned somewhere close to the end).

    Looks to me like a lot of FUD.

    Reading the patent claims this doesn't look so much like IPv6 (and certainly not a fundemental part of IPv6 - it resembles IPv6 stateless address autoconfiguration, but only vaguely). What it looks like is IPv4 linklocal addressing, which has shipped in both MacOS and Windows for several years, and is a draft that is either just about to be approved or has already been approved as a standard. See draft-ietf-zeroconf-ipv4-linklocal-17.txt [ietf.org] The really unfortunate thing is that linklocal addresses are quite useful on isolated networks, but are really harmful to applications unless they're turned off when a computer has a "real" address assigned by manual configuration or DHCP. And from a quick reading the patent would appear to apply to any implementation that turns off linklocal addresses under such conditions.
