How Do I Put an Invention Into the Public Domain?
Nefarious Wheel writes "I have a couple of inventions — mechanical devices, based on physical principles — that I believe could transform certain aspects of industry. The trouble is, I can't afford to file patents, and even if I could, I'm not sure that would be the best way for these devices to be made available as widely as I'd like. Is there some way to publish the details of these innovations in the public domain in such a way as to protect them from being snaffled away by some patent troll? I'd be happy with a contribution (or simple attribution) model for recompense, which could be zero to whatever, but that's not as important to me as getting the ideas out there for anyone who wants to use them. This isn't copyright, and I know of no patent equivalent to Creative Commons. In short, what's the best way to protect an invention against someone filing a patent on it, short of patenting the device yourself? Can this be done?"
But patent examiners aren't likely to find such published prior art unless you publish it in something that patent examiners actually read. Google defensive publication brought me a Wikipedia article explaining the concept and a short guide.
File a statutory invention registration with the patent office.

Alternately, you can file a provisional patent application, and then just abandon it by not filing anything else for a year.
Either of these will become part of the patent office's database and thus will be searched by patent examiners.
Once something is published, it becomes "prior art" and someone else can't patent prior art and obvious extensions to prior art.
And also once you publish it, you can't file for a patent on it outside the US, and you can only file for a US patent within a year.
While in theory this is technically true, the reality of it is that filing a patent... even if you never intend to collect royalties or even sue somebody for patent infringement if you discover it in the future... is still the most viable option.
One situation I had with a former employer was an expired patent application that hung in our engineering conference room for years.... where the company was sued by a patent troll who had filed a nearly identical patent application for the very same concept and was claiming prior art. In that case, the troll was hosed (legally speaking) because prior art was clearly established and certified by the USPTO... showing that the patent was clearly invalid and forcing the judge to dismiss the case. The patent attorney hadn't even listed this prior patent as a disclaimer of prior art when a simple search of the patent database would have turned it up.
The company I worked for would have been taken to the cleaners if it wasn't for that patent which had been filed by an earlier employee. Yeah, it was fun to see first hand how valuable defensive patents could be... and it was even funnier to see that plaque temporarily be taken down as it was presented in court as prior art. Yeah, that step wasn't strictly necessary, but it made an impression on the judge as well that proved to be quite positive.
In this case, you need to use the patent system against itself just as the GPL uses the copyright system against itself. The patent system respects itself, but it doesn't think stuff created out of this environment is worth much.... witness some of the idiotic patents that have been filed such as one about ROT-13, one-click shopping, and the LZW algorithm. While all of these had clear prior-art in published journals (like ACM publications), that hasn't been sufficient to prove prior art in a legal sense, unfortunately, and patents were not only granted but enforced.
And no, I don't love the patent system (I wish it were completely abolished), but it is an unfortunate evil in today's engineering environment. I have yet to meet a single individual that I know personally or have been able to shake their hand who has made a single penny off of a patent, yet I know dozens of individuals who have had them granted and have even developed patent-worthy concepts of my own.
I've used Research Disclosure publications which I'm pretty sure U.S. patent applicants are required to look through in their search for prior art.
