Hi Walter, Couldn't one just publish the idea in a magazine, with the author clearly listed? I thought that such a thing would clearly establish who originated the idea, unless someone could show that they came up with it before then. Even so, they would have to make such a claim within one year of the magazine publishing date, I think.
