This is right e.g. for the patent system that we used to have in 
Germany. But as far as I remember, it is wrong for the patent system in 
the US. There you just have to prove that you were the first to do it, 
and it is not to your disadvantage that you published it yourself 
beforehand.

It is just annoying.

Kind regards,
