Can I still submit assignment documents by mail to the USPTO?
Yes, you can still submit assignment documents by mail to the USPTO, although electronic submission is strongly encouraged. If you choose to submit by mail, send your documents to:
Mail Stop Assignment Recordation Services
Director of the USPTO
P.O. Box 1450
Alexandria, VA 22313-1450
However, as noted in MPEP 302.10: “The Office strongly encourages electronic filing of assignment documents using EPAS, because assignment documents filed electronically are recorded faster and are less likely to become lost or misplaced.” Therefore, while mail submission is an option, electronic submission through EPAS is preferable for faster and more secure processing.
