This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

For those choosing to file international design applications on paper with the USPTO, the correct mailing address is crucial. According to MPEP 2905, paper-filed international design applications should be mailed to:

Mail Stop International Design
Commissioner for Patents
P.O. Box 1450
