How should a Demand be filed with the USPTO?
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:

If hand-carried directly to the USPTO:
