How should a Demand be filed with the USPTO?

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.

According to MPEP 1865, Demands filed with the USPTO should preferably be submitted via the USPTO patent electronic filing system (e.g., EFS-Web) by registered e-filers. For those who are not registered users, other acceptable methods must be used.

If mailed to the USPTO, the demand should be addressed to:

Mailing address for delivery by the U.S. Postal Service:
Mail Stop PCT
Commissioner for Patents
P.O. Box 1450
Alexandria, VA 22313-1450

If hand-carried directly to the USPTO:
Customer Service Window, Mail Stop PCT
Randolph Building
401 Dulany Street
Alexandria, VA 22314

The Priority Mail Express® provisions of 37 CFR 1.10 may be used to file a Demand under Chapter II in the USPTO. Demands may also be submitted via facsimile.
