Google and Others Sued For Automating Email 273

Dotnaught sends us to InformationWeek for news of the latest lawsuit by Polaris IP, which holds a patent on the idea of responding automatically to emails. The company has no products. It brought suit in the Eastern District in Texas, as many patent trolls do — though the article informs us that that venue has been getting less friendly of late to IP interests, and has actually invalidated some patents. The six companies being sued are AOL, Amazon, Borders, Google, IAC, and Yahoo. All previous suits based on this patent have been settled.

      The patent isn't just email filtering, it also covers emailing the sender a canned response (from a repository) based on the content of the message. I'm sure procmail can do that, but unless they procmail included an example of doing just that, it's not prior art. I'm sure prior art does exist, though -- when usenet was king, moderated newsgroups did something similar.

        Although my college was already on a T1 line when I went there in 1991, others had talked about the time before when the school only had UUCP connectivity ( which would be around 1988-1989 ). A user could send a message to the remote system ( a bigger university which had a dedicated line ), which would automatically fetch the file with ftp, then send it back to the user on the next UUCP exchange. The driving force for installing the T1 was because students using UUCP to request files from remote systems

            My first point was that it is very widespread now, and my second point is that someone probably thought of it a long time ago. Since it was not based on a news event witnessed by half of the world's population, one could likely assume some sort of normal growth model for that technique. Your example fails on this point. Of course, because it's only "likely", I used the word "guess".

      Absolutely - Procmail covers so many bases in terms of "automated stuff that can be done with email" that it's hard to see how it wouldn't be prior art for just about any patent issues in this area.

      On a broader topic, I can see the day when law firms engaged to provide legal defences against software patent claims start to employ older geeks specifically to identify prior art solutions. It's gotta be cheaper to keep a bunch of us around on some sort of "professional retainer" basis than to engage paralegals to trawl through old patent documents (and I'd "Procmail" probably wouldn't come up in a patent document search anyway) - many of us who've been around for a while would've thought "Procmail" before we'd finished reading this summary.

    message received.
    sendmail looks up in it's address base and either a) forwards to appropriate mailbox or b) replies with undeliverable.
    further details within the rule base may determine whether additional copies need to be forwarded to other mailboxes, or further responses are necessary.
    integration with things like spamlists, virus scanners all add to the *automated* handling of e-mail based on rules.

    just because they are adding additional automation to the last leg in the e-mail journey doesn't mean that the mail was already processed, scanned, had rules applied and copies made/forwarded by the server before the client ever saw the message.

    Obvious patent - apply server rule processing to email client.... BFD.

    IIRC, Majordomo and GNU Mailman predate this patent by at least six years. In fact, the current mailman-users mailing list's earliest archive is May 1998, so work would probably had to begun far before that. A little research proved that LISTSERV predates all of them, actually. From Wikipedia:

      I think they all skip the "requiring assistance from a human operator" classification in the patent. Which is where it matters since there's obvious prior art for a purely automated system - once that interprets the mail and forwards it to a human operator with a prioritised list of potential replies seems less likely to have such obvious prior art. Though it seems likely someone did this earlier, it's an obvious way to use a imperfect classification system after all.

    Majordomo did just what the patent says. It parsed a message, determined whether it could be automatically responded to (as in subscribe, unsubscribe, list members, help, list charter, etc) or needed to be forwarded to the list owner. Majordomo did much of the list management entirely automatically, hence it's name. They describe something entirely comprised of Majordomo's functionality. Our company was using Majordomo to manage email lists in 1995, well before this patent was filed.

The DECsystem-2060 system running TOPS-20 at The Ohio State University Computer Science Department was connected via a network I believe was CSNET. While using that system I learned of a facility to obtain RFC documents that described things like the format of email headers ... by sending email to a specific email address. It would them email the document back. I received over 20 some RFCs that way. They came back within a couple minutes, so I doubt they had someone just sitting there answering it. I suspect this was an early IETF or ARPA facility. Maybe they have some documentation that still remains about this. Maybe it's in an RFC itself. I'll have to Google for more of this.

    let us not forget the email-to-ftp gateways that BITNET [wikipedia.org] used to have. Another example is the AutoDRM [seismo.ethz.ch] protocol used for seismic data, which dates to 1991.
  • ...aren't they going after Microsoft, the postfix folks, etc? They make software that can be used to send automated emails, too. For that matter, I'm sure Novel has a product that does as well. That doesn't even speak to all the "shareware" mail software that can do the same.

    Why just pick AOL, Amazon, Borders, Google, IAC, and Yahoo?
    • Precisely. Why dont they go after IBM's Notes which has an auto-response feature???
      If they can sue a kid, they can sue a gorilla.

      Oh wait... that gorilla can bleed them to death through attrition, slowly and surely.

      Maybe they are setting precedents and then plan to sue IBM later.
      If that is the case a pre-emptive strike by IBM is necessary.

      IBM ! are u listening???
  • Automatic responses to email, SMTP specifically, is discussed in RFC 822. This RFC was published on August 13, 1982 and is listed as an industry standard.

    4.4.4. AUTOMATIC USE OF FROM / SENDER / REPLY-TO

    For systems which automatically generate address lists for
    replies to messages, the following recommendations are made:

    On the Debian bugs system page [debian.org] it says the first version was realeased in 94. I'm not sure how much was implemented, but in it's current form it's really very much alike the patent (what is said in the abstract anyways.

    Listserv [lsoft.com] might also apply, if they had advanced mailinglist management in the beginning.

      a classifier for classifying the electronic message into at least one of (i) being able to be responded to automatically; and (ii) requiring assistance from a human operator.

      This is the most important part, I think but this here is the most comical, so if I use utf-8?:

      15. The method of claim 1, wherein the electronic message is received over an electronic data communications channel.

      16. The method of claim 15, wherein the electronic data communications channel is the Internet.

      17. The method of claim 15, whe

  • Two words to Polaris: procmail, formail.

  • Back in the 1980s I remember using at least two services that provided software in response to email, which would seem to be prior art. One was run by Bell Labs, the other by one of the national labs (Sandia? Los Alamos?). Bell Labs distributed some of their Unix utilities this way. Whatever lab it was distributed mathematical software - stuff for linear algebra, differential equations, statistics and so forth. In both cases, you sent a message along the lines of "get package foo" and you get back email co

  • Sjeez - how far back do you need to go? What about email reject messages - that would be prior art. Vacation messages? List control messages? I've seen this years ago on Bulletin Boards (i.e. pre-Internet) so there's a mountain of prior art.
  • Back in late 1994 I wrote a small application which generated Star Charts served via email.

    Based on a simple set of commands describing where in the sky to centre the chart, the field of view, limiting magnitude, objects to include etc, and it would generate a Postscript file of the generated chart based on those commands.

    It was built up using both bash and perl, and the commands fed to it directly from sendmail, so when you sent an email to it's own email address, you received a response with the required
