I think you can send in your patent application on paper. Two other variables in the game is that in the US you can patent something that you have published some time later and that if you're unlucky the NSA says your invention is intresting and will steal it for "national security" reasons. So the "right way" is to first send in the application to EPC (European Patent Office), then to the US Patent Office, and then publish it. But I think we're getting a bit off topic... :) /assar
