MailBlocks sues Earthlink over Anti-Spam Tech

goombah99 writes "Mailblocks is suing Earthlink , claiming patents on Challenge-Response as a means of blocking spam. Slashdot recently discussed Earthlink's plans to implement a challenge-response email system. The next day mailblocks filed suit to defend their turf in the $118 million dollar anti-spam solutions market. MSNBC has a complete discussion."

      In fact, I posted it to Usenet later in '96. I'm pretty sure that you can find lots of similar prior art in the google usenet archive.

      If I were Earthlink, I'd let Mailblocks keep their patent. Challenge-response was probably a reasonable solution half a decade ago. Filters have improved since then and with a well-maintained filter list of domains PLUS a working Bayesian filter there is no reason to make innocent senders go through the hassle of verifying themselves while at the same time doubling spam traffic (one spam received = one challenge response issued, so instead of a billion spams per day we have a billion spams plus a billion challenge/response mails).

      C/R technology is inconvenient and obsolete. I'm not even sure why Earthlink decided to implement such an obsolete approach that has the side effect of doubling the amount of emails related to spam.

  6. Is this paranoid enough? by jc42 · · Score: 5, Interesting

    Wouldn't it be interesting if the "privately-funded" Mailblocks were to win and then refuse to license their patent to anyone? Or maybe offer to license it, but for exorbitant license fees. Then, 20 years from now, we'd find out that their private funding came from companies with an interest in Direct Marketing? Or that Mailblocks itself exists as a marketing tool, to collect email addresses and sell them?

    One of the very real uses of patents is to prevent people from using the technology.

    So am I paranoid enough yet?

    I know that challenge response has been around longer than thatPRIOR ART.
    And challenging Earthlink is a bit foolish. All Earthlink needs to do is come up with the hundreds of thousands of examples of Challenge-Response systems in use as early as 1995 in order to verify an actual person was on the other side.

  8. mailing lists prior art? Patents = good this time? by SuperBanana · · Score: 5, Interesting

    Majordomo, Mailman, elzlm...almost all mailing list software sends you a confirmation email, requiring your reply(nowadays via a URL with an embedded authentication string, or via email simply by replying.) Kinda seems like prior art, since I'm guessing "Mailblocks" hasn't even been around as long as majordomo, which dates back into the Dark Ages.

    However, in all honesty, this is probably one of the few cases where everyone wins- for many of the reasons folks cited in the comments on the last article that mentioned Earthlink's move... challenge-reply is a VERY half-baked idea, and anything that supresses the market for that software(ie, patent) is a darn good thing in my book.

    I'm a mailing list manager, and if Earthlink does manage to get out of this one and fire up the challenge-response business, I'm damn tempted to simply block every earthlink user, possibly at the mailer level, because the users simply aren't smart enough to handle whitelisting the mailing list(s). Hell, most of the hotmail/yahoo mail users can't even keep their mailboxes under quota. We're talking rocket science compared to keeping your mail folder clean...

  13. This is like "can't defend yourself against crime" by MickLinux · · Score: 5, Interesting

    Just my thought here: Many states, maybe all, have made spam a crime.

    But they have not been effective in stopping it.

    Now, normally, when I am victimized by a crime, I am justified in defending myself. Mailblocks, however, is saying "You can't defend yourself against this crime, because we own the intellectual property for the methods of defense"?!?!

    Okay, so whenever a new technology comes out, the mafia just needs to figure out (1) a way to victimize people (2) the best ways to defend against it. Then patent the defenses, and subsequently hit people from both sides.

    Our government is coming to a real decision. Either defend IP at let criminals roam free, victimizing all and destroying the economy, or give up IP, and maintain order.

    Meanwhile, Ralsky and his friends are going to be down at the patent office in a flash.

    Something is rotten in the state of our legal system.

    This looks like it's becoming another "unholy alliance" like the virus / anti-virus market. It's as if the net had no native problems, so people have had to think up some so they could sell solutions for them. I wouldn't care if there wasn't so much collateral damamge to the net's reputation and so much extra effort on my part for "trash removal" in my corner of the net.

    I'm a proud capitalist, but this is sickening. It's like embedding nails in the road to increase sales of tires and towing services. Surely if there were ever a "solutions market" that deserved to be trashed by OSS, this is it.

  16. I have possible prior art from 1993/1994 by Dr.+Zowie · · Score: 5, Informative
    In 1993/1994 I was a graduate student at Stanford University and designed a simple challenge/response spam filtering system that works substantially the same as the one being advertised. Unknown incoming addresses were entered into simple ASCII database, and the associated mails were stashed in individual files in a particular directory. Unique challenge letters were to be sent out, and the mail was to be delivered or canned depending on the response (or lack thereof) from the challenge.

    I never finished implementing the system (I wrote my dissertation instead) but still have a midsized collection of emails about it.

    Challenge/response has got to be "obvious to one versed in the art" -- I can think of at least three other people at Stanford who had the same idea at about the same time.
