Amazon Patents User Viewing Histories

Chris Cleveland writes "Yet another astounding patent from the USPTO. I was browsing the patent database, and discovered that Amazon received a patent today on using customer viewing histories to generate recommendations. If a customer views product A, and then later views product B, and you use that to infer a relationship between A and B, then you've infringed on this patent. This patent is a continuation of an earlier patent (#6,317,722) on using shopping carts to generate recommendations. When will this stupidity end?"

    This is the exact same thing done in aggregate, and I am sure someone will use it to invalidate this dumb patent.
    Don't be so sure. To invalidate this dumb patent will require _lots_ and _lots_ of money. How many companies out there will be willing to pay that bill? Most will just pay Amazon a _much_ smaller "fee" to use this "innovative and unique" patent.

      Google has plenty of ridiculous patents, one pointed out by a poster here is highlighting search terms. BTW google infringes on at least one Amazon patent that I know of, have they been sued? Also it seems to me that very few people are aware of just how narrow most patents really are, while the abstract may claim something very basic, when you get to the calims and the implementation details it becomes much more narrow. That said there was a bountyquest reward (posted by tim o'reilly) for finding prior art on the One Click patent (the only one Amazon has tried to enforce), it went unclaimed as the was none.

  3. actually, a detailed patent by viva_fourier · · Score: 3, Informative

    Some patents filed are pretty general and can be summed up in a few words like "using customer viewing histories to generate recommendations." This particular patent, however, is not all that general and is actually very detailed, yet broad.

    It details not only the weighting system used to generate the recommendations (recently purchased + highly rated = higher weight), in the same category, but in other store areas as well. It weights differently based upon whether an item is placed in the cart, searched for, placed on the wish list, bid on in online auction(?), purchased as a gift, or merely favorably reviewed.

    So, Amazon is basically saving their customer's viewing/browsing tendencies as data. Now, they've patented the usage of this data to generate more sales. It seems like a good idea to me.

  4. Prior Art? by FlukeMeister · · Score: 4, Informative

    I actually have a direct example of prior art that pre-dates this patent by over 2 years. Back in 1999, whilst working with Broadvision in both the UK and US, I was involved in a number of projects that implemented the exact method described in the patent.

    Getting this absurd patent overthrown would be absolute child's play for anyone familiar with mapping taxonomy systems to observation logging and user ratings, which were common practice for anyone using systems such as Broadvision back in the late 90s.

  5. recommendations, circa 1999 by yppiz · · Score: 5, Informative
    As one of the references cited by the patent (US Pat. 6,691,163), I think I can make an informed comment on it.

    At the time the patent was filed, it was extremely uncommon for systems to make automatic recommendations based solely on the behavior of users. When I did my work at Alexa Internet (which was acquired by Amazon) in the late 90s, I had to solve a number of issues which had not been dealt with, both from an engineering perspective and from a quality of results perspective -- few companies, and no academic researchers that I am aware of -- had both the amount of data and the technical talent required to process it in order to test and refine recommendation systems based on transactional information.

    My work in this area became Amazon's "customers who shopped for X also shopped for Y feature." Greg Linden, the first name on this patent, is now doing interesting recommendation work with his site Findory.

      Case-based reasoning is a far cry from what this patent is describing.

      Specifically, CBR assumes a symbolic rich representation of prior cases, and a pre-built distance function for measuring the similarity of the current situation to prior cases.

      Most of the AI in CBR is in 1) choosing the right representation, and 2) coming up with the right similarity metric.

      In the technique that Linden et al have patented, they make no assumption about a representationally rich framework for describing events -- in other words, they didn't have to spend months coming up with the right representation of the data. Also, and more importantly, they probably did not pre-build a similarity metric to match against prior cases. Instead, they applied statistical techniques to come up with the right similarity metric.

      There are likely other differences -- I don't think CBR circa 1999 was applied to commercial transaction data in order to generate sales recommendations. B

      The nearest I know of is that both CBR and Memory Based Reasoning likely were tried by other companies to do credit card fraud detection, which itself is a transactional problem involving large amounts of data. Still, that's pretty far from "I see you're buying a Sony plasma TV, would you also like to buy a Denon DVD player?"

    Last time I heard, patent application was around $10k per country and around $100k for worldwide filing.

    Filing a patent in any country prevents anyone else from filing the same patent in all others but only provides legal enforcement in the countries where the patent was was filed. In most cases, inventors can file in other countries as necessary to extend legal protection but doing it incrementally can quickly cost more than an international filing.

    What is the school posessing in your sentence?

    Please do not post on slashdot until you have completed our short course, "Apostophe 101"

    APOSTROPHE 101

    Module 1: Possessives

    In English, possession is usually indicated by adding an apostrophe - s to the end of a noun.

    e.g. John's car

    Module 2: Plurals

    In English, a plural is usually indicated by adding an s to the end of a noun

    e.g. John's car has five wheels.

    Module 3: Contractions

    In English an apostrophe is often inserted to represent missing letters

    e.g. John's car has five wheels. The fifth wheel's in the trunk, though
    or John's not counting the steering wheel in this analysis, by the way.

    Here the missing letter is the letter "i" - i.e., "The fifth wheel is in the trunk, though" or "John is not counting the steering wheel..."

    Module 4: The exceptions

    1) Nouns that end in an s can indicate plurals or possessives with the addition of an apostrophe

    e.g. "Thomas' bicycle has but two wheels", rather than the utterly agonizing "Thomas's Bicycle...".

    2) Usually, its is only apostrophised to indicate the contraction of "it is"

    e.g. The law was rejected because of its ambiguity. It's quite likely that it will be revised and reintroduced at the next session.

    But this changes when "It" serves duty as a proper noun:

    "The high spot of the Adams Family convention was the costume pageant. I counted about 200 Morticias, 180 Gomez' and 89 Cousin Its. I'd forgotten how long Cousin It's hair was"

    tough tarts, all amazon has to do is claim prior art and that company can sit and spin. No need to get your own patent on it.

    I know a patent lawyer that would disagree, and actually proposes "patent first" on items in order to protect companies from getting burned. In fact, he worked with several mid-size companies when Unisys went nutty. Several of these companies were the first to use the .GIF format on the WWW, and had legitimate reason to argue against Unisys's claim to own the patent due to the doctrine of equivalents applying to essentially everything.

    This patent was filed so amazon could prevent competition from using this "technology". It's got nothing to do with protecting itself from lawsuits and everything to do with amazon reserving the right to sue others.
