First of all I'd like to thank everyone who replied - there was such a flood of mail that I thought I'd better post a public "thankyou" rather than send out thousands of individual thankyou notes :->. Anyway, here's a (brief) summary of all the replies: The basic message I got from *everybody* was: Publish it it with as wide a circulation as possible. The main idea is to be able to prove that you thought of it before anyone else did. You can then cite it as "prior art" and no patents filed by others after the date of publication will be granted. Publication on the Usenet may be enough, but the ideal thing would be to put it in something like a journal or conference proceedings (I know from personal experience however that articles can often spend *years* in the pipeline before they get published). If two people try to patent the same thing, whoever can produce the earliest dated publication (from a reputable source) wins. Even something like putting an ad in a newspaper should be admissible (and a lot faster than putting it in a journal). When you publish your idea, make it as general as possible to avoid some clever lawyer convincing a judge somewhere that X's invention isn't the same as yours and that it's a non-obvious improvement. The more things you list in detail, the less things X can "invent" later since you've got proof you already thought of them. Finally, if someone tries to patent/copyright/whatever a derivative work from what you've done, sue their butts off (or threaten to). If you don't want to put the idea in the public domain, the only thing to do is patent/copyright it and use this to fight off others. Thanks again for your replies... Peter.
