What kind of papers? We are talking about prosecution papers, that must be addressed in a timely manner to prevent abandonment. The question is: Does the PTO send “Office Actions” (the term for official, formal replies to applications and amendments) to foreign contries?
When I said: ‘verify this’, I meant with the PTO or a qualified source. I am not one. As I said, get it from the horse’s mouth.
I might be wrong, but I am sure I read it either in the USPTO site many moons ago, or in “Patent It Yourself” book by David Pressman, which BTW should be very handy to any inventor, whether or not they intend to "Patent-It-Themselves.
The link below answers most of the questions that anybody may have about patenting in a very general way. In full compliance with Murphy’s law, this link failed to specifically address the issue at hand, i.e. whether or not the PTO will mail O.A. outside the US.
Beyond Brendan’s question, and since it is a fact that “business are to be conducted in writing” whether using or not a US address, I would determine the speed and reliability of international correspondence. I come from a country that well… you never know.
Enjoy reading from the horse’s mouth.
CAVEAT: I just realize the info is obsolete. They have a chapter about the “Disclosure Document” program, which is no longer in effect. You can not fully trust the horse, I guess.
