Prior Art to Pinpoint vs. Amazon, from 1980's?

Gary Robinson writes "I'm in a fairly unique position with regard to the Pinpoint vs. Amazon case since I built a system in the mid-1980's which is commonly regarded as the first active service based on collaborative filtering. It was a voice-mail-based dating service called 212-ROMANCE. I still have the 8-inch CP/M source code disks as insurance against CF-related patent lawsuits. Today I've posted a discussion of the Pinpoint vs. Amazon case in the context of that prior art as well other prior art from the 1980's."

    Look, there are still things that are patent worthy.

I question the overall usefulness of such a device (getting rid of standing water around your house may be smarter, although I suppose this would be helpful if you had a small pond) but it seemed pretty unique and clever.

    The process of proving prior art should be more streamlined, perhaps, and the level of interest at the patent office of yanking improperly issued patents definitely needs to be increased, but doing away with this system is only going to punish the small inventor as illustrated above.

    No, you can't even prove that. The basic supposition of logic is that facts will tend to point to a correct answer. This is why you can't prove a negative, because your non-event has no facts associated with it. Your monkey doesn't exist, therefore there are no facts that lead to the conclusion that he doesn't exist, therefore there is nothing to base a decision on.

    One should have to prove "no prior art"!

    The way it works is exactly the opposite of that. Prior art does not invalidate a patent, it just make the patent dependent on having the rights to the prior art as well.

    Unless your patent is exactly what the prior art is (hardly anything is exactly something else (!)) or some subset of it, finding prior art will not prevent the granting of a patent. Also, many patents that are flaged as outrageous by armchair lawyers on slashdot are not as broad of scope as they seem due to the prior art that is listed in the patent.

    The process may be broken, but not as badly as you'd think from all the postings you see around here.

    Why? Because while you may have similar sources of data in both areas, namely personal profiles or "shopping" transactions, there is no guarantee that the data has the same properties in these different domains, and so there is no guarantee that the same algorithm will work in the two domains.

    And without this guarantee, it is not necessarily "obvious to a practioner in the field" that one would overlap the other.

    Prior art by definition isn't secret stuff- that comment would imply

    I don't understand how I could be implying that prior art is secret when I specifically say it's disclosed right in the application...

    Prior art is used to prove that an 'invention' has not taken an inventive step, meaning someone skilled in the relevant art could reasonably be expected to think of the same invention upon reading the public 'prior art,' without any particular inspiration.

    Sure, that's one use for prior art, but there's more to it than that. A novel extension of prior art, or even a novel implementation of prior art can be patentable. In those cases prior art is a building block for the new patent, which is exactly the opposite proving the invention unpatentable.

    Also, there's more to obviousness that somebody skilled in the art being able to easily come up with the same solution. The problem being solved has to be obvious too. Somebody skilled in the associated art would never come up with the "obvious" solution without realising the solution needed o be found in the first place. It's easy to call something obvious in hindsight.

    If patents on systems implemented in software were granted from day one, the software industry would be very different than it is today. Other industries, electronics for example, deal with patents and licensing on a day to day basis and the state of the art keeps advancing. One could argue whether it would be better or worse, but at least it would be consistent. What we have today is the worst of both worlds. We have a patent office accepting patents while they have no concept of the state of the art or prior art.

    Personally, I feel what the patent office is missing is the idea that computers are designed to be infinitely configurable machines, and that software just sets the machine to a particular configuration. Being able to patent software is like being able to patent a particular Lego layout.

    But just to let you know, if it would have been possible to patent Hello World, and if the patent to it had coincided with the publication of the first edition of the book The C Programming Language (long after string output had implemented in software), then the patent would have expired by now.
