Defensive Patent Publishing

Mises post. Archived comments below.


As I note in my post “The” Purpose of Patent Law, it is commonly said that “the” purpose of patent law is to incentivize innovation. After all, the Constitution’s patent and copyright clause says Congress is empowered to secure “for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries”–that is, to set up copyright and patent law–in order “To promote the Progress of Science and useful Arts.” It is promotion of innovation–”useful Arts”–that is “the” stated purpose of patent law, at least as stated in the Constitution. But the Patent Act seeks to accomplish this goal by granting to the inventor a limited monopoly1 in exchange for disclosure. That is, patent law encourages disclosure of ideas by rewarding it. The idea is that inventors would try to keep their ideas secret (protected as a “trade secret”) out of fear competitors could copy them. So by giving the inventor a monopoly that provides him with a temporary respite from competition, he has less fear of disclosing his ideas–and, in fact, the patent law requires full disclosure as the price the inventor pays to receive the monopoly patent grant.

And it is true that hundreds of thousands of invention disclosures are made public to the world each year when patent applications are published (usually published at about 18 months after they are filed). How useful this is, is debatable. After all, many, if not most, innovative products, when sold, can be reverse engineered. That is, the inventor has an incentive to profit off of innovations by incorporating them in products, and when the products are sold competitors, and the world, can learn things from the product themselves. If I invent a better mousetrap, when I sell it people learn about the innovations incorporated in it. In fact the seller has an incentive to explain these innovations in order to sell it. So many patent disclosures are just redundant.

In any case, there is another, more perverse, way that the patent system encourages invention disclosure: defensive patent publishing. If you come up with an inventive process or design and are using it in your business, you can patent it, sure. But you might not want to waste $20k. Or you might not have millions lying around to use to assert it. Anyway most of these patents are taken out defensively–a sort of “porcupine” defense strategy designed to keep the others with patents from suing you, for fear of being countersued. So we have all these companies spending millions to collect patents just so they don’t sue each other (this erects barriers to entry that keeps little guys out, of course). The point is building up a patent porftolio is a big expensive waste that some companies cannot afford.

Unfortunately, if you  fail to patent your own inventions, then the risk is some other company may later independently invent and patent it, and sue you, forcing you to pay damages or even stop using your own invention (there is no general defense for prior users or independent inventors).

In response to this unfortunate situation, one thing you can do is make your invention public in such a way that it becomes part of the public “prior art” to make it more difficult for someone to later file a patent on that invention. There are several ways to do this. One is to file a “statutory invention registration” with the US Patent Office, but this is complicated and expensive (about $920 or $1840; see 37 CFR sec. 1.17(n) and (o) fees). Another would be to self-publish but this has drawbacks. Research Disclosure offers this service, but it costs $120 per page. Until someone comes up with a free, reliable wiki type open source solution for this (I have half a mind to use the Mises Wiki to provide such a free platform to help people defend themselves from the patent vulture), probably the best option is IP.com’s Prior Art Database, which costs $225 per publication for the online version. (A related idea is the idea of an “antipatent.”)

It’s a bit sad that the patent law has not only twisted the arms of patentees to induce them to make public things they would otherwise keep secret, but that it’s inducing innocent, non-patenting companies to have to drop their knickers just to avoid the cost of patenting or of being a victim of a patent suit. But given the current system, this is an option that is not a bad one for companies who have this concern.

“Until someone comes up with a free, reliable wiki type open source solution for this….”

How about Wikipedia?

Great news on the IP front, Stephan: Sarah and Bristol are intellectually protected (IP-ed). In the same vein, Beavis and Butt-Head are back!

The logic behind the patent still doesn’t make sense. It all boils down to this, “If I sell something I invent, someone else can copy it, sell it, and cut into my profit margins. Therefore, without a patent system, I’ll make sure I receive no revenue at all from my inventions, thus making myself even worse off had I sold it into a patent-free market and enjoyed the high first-to-market profits until someone else came by with a competing product.”

Ya, inventors will end up not selling their product, getting nothing at all, because they’re scared they won’t get as much had it not been a monopoly. Makes no sense.

Stephan, you really CAN’T expect me to let you get away with your claim that Research Disclosure is not as good an option as ip.com!
As soon as I read your piece, with much of which I sympathise, I grabbed the nearest copy of Research Disclosure lying on my desk (November 2010). It is not an untypical edition. More than half of the disclosures it contained were of one or two pages – that is, either the same price or half the price of ip.com.
What you omitted to say was what your money bought you. Let me mention two key advantages of publishing with Research Disclosure.
1) Research Disclosure, unlike ip.com, has “PCT Minimum Documentation” status. For readers unfamiliar with the term, this means that PCT searchers are required to consult the non-patent prior art contained in Research Disclosure when assessing any new patent application. As you can imagine, non-patent prior art – which includes conference papers, magazine articles, even ingredient wrappers on chocolate bars – is so voluminous that only a tiny percentage is ever considered by examiners, whereas they are obliged to consult Research Disclosure (and I fear that your dreamt-of Wikipedia disclosures will only add to the volume of disclosures that they do not read). The practical result of this is that examiners are much, much less likely to grant “bad patents” that infringe our disclosures. Thus Research Disclosure disclosers avoid all the expense of going to court to have a bad patent struck down.
2) You do not quote comparable prices. Ip.com charges a further considerable fee to print your disclosure in full; Research Disclosure includes full print in its $120 fee, with distribution of the journal to patent offices worldwide (as well as leading public and academic libraries). Why does this matter? Many courts will not accept online disclosure as sufficient proof of the date of disclosure. Indeed, the European patent board specifically ruled in the case of Konami that internet archive services do not yet provide sufficiently secure evidence of a publication date. (Case Number: T 1134/06 – 3.2.04 Konami Corp, 16 Jan 07).
According to David Rogers, Legal Member of a Board of Appeal at the EPO, “practitioners who are looking for ‘killer’ prior art would be well advised to stick with the traditional print means, unless they have a considerable body of evidence to support the reliability of an internet disclosure. [Konami] also sets out how a party can cast doubt on the reliability of such disclosures.” (David Rogers, Documents on the internet as prior art, Journal of Intellectual Property Law & Practice, Vol. 2 No. 6, June 2007, pp. 354-355)
In the fifty years that Research Disclosure has been publishing, disclosure services have come and gone. We pride ourselves on charging modest fees when you consider the work involved for a comprehensive and reliable service that has never been matched.

Thanks for the additional information, Michael! I’m happy to let you clarify matters and make your case. I will edit the post to direct readers to your comment.

I was not aware the disclosures were often that short. I’m thinking like a patent lawyer of 30 page documents and so on, so I was thinking the price would be cost-prohibitive for the typical layman who just wants a way to make his idea public domain in part to lower the risk of someone else patenting it.

Note that when I said “best option” I was talking about price only–as for other possible advantages of your service over IP.com, I’m glad you clarified. I had seen your PCT minimum documentation comment on your site but had not reviewed it closely. You make some very good points. I also tend to agree with you that a paying service like yours is probably better than a free wiki one for many reasons, including in part the volume issue you mention. Finally, I was not aware that some offices still do not trust online archiving; this is sad, but I’m not too surprised that state agencies would be so luddite and behind the times–but it does highlight the importance of print publications.

In any case, from what you have said, your service does sound better than the other one, at least if you have only a few pages to disclose. Again, thanks for the clarifications!

    Just to let you and your readers know that we recently launched a patent research disclosure service which allows inventors to submit their documents and have them published on our online database and also in printed form. This printed journal is then distributed to all the major patent offices around the world.

    We have purposely designed our system to be fair to those users who submit large quantities of documents, as the price per page falls dramatically for volume users. Both publication and searching can be ordered directly online at http://www.iplab.co.uk/patent-research-disclosure
