Rarely have I seenstatements made with such force and yet be totally wrong.
The original posting was correct. So long as you get your first filing for
a patent in before you submit for publication elsewhere, you then have a
one year grace period for filing anywhere in the world under the
International Patent Convention. This applies to virtually every country
in the world. So it is PERFECTLY SAFE to show your material to referees,
post it on the Web, etc. after you have made your first filing and before
you do foreign filings under the International Convention. The only
proviso is that under the Convention you MUST file all the patent
applications in other countries within a year or you lose the earlier
priority date. Once you have filed your first patent application, there is
no need to insist on non-disclosure agreements with anyone else, though it
very helpful if you draw peoples' attention to the fact that you have filed
a patent application. The gracetime period allowed in US law is something
completely different, allowing you one year from the date you first show
the invention in public before filing your *first* patent application.

I do not know anything about the RSA case, but I suspect they failed to
file outside the USA under the International Convention rules. The
Convention has certain strict bureacratic rules that it is easy to fall
foul of. But the principles behind it are clear and hundreds of thousands
of patents are safely filed under the Convention every year.
