Correspondence Related to Patent Prosecution

All new patent applications or correspondence related to patent prosecution may be submitted using EFS-Web, the USPTO’s Web-based patent application and document submission system. EFS-Web utilizes standard Web-based screens and prompts to enable you to submit patent application documents in PDF format directly to the USPTO within minutes.  In the event you do not use EFS-Web when filing new patent application(s) and correspondence relating to patent prosecution with the USPTO, these documents must be hand delivered to the USPTO in Alexandria, VA or mailed via the U.S. Postal Service (USPS) to the USPTO at the address below to receive the date of deposit with the USPS:

  • Commissioner for Patents, P.O. Box 1450, Alexandria, VA 22313-1450.

Please note – To receive the benefit of a certificate of mailing or Express Mail, new applications and other patent correspondence sent via the USPS to the USPTO must be addressed to the Alexandria, VA address above.  See 37 C.F.R. §§ 1.8, 1.10.  New applications and other patent correspondence sent via USPS to the USPTO at an address other than the Alexandria, VA address will receive a filing or deposit date that is the actual date of receipt of the correspondence by the USPTO, and not the date the document was deposited with the USPS.  Also, effective November 15, 2011, any regular non-provisional utility application filed by mail or hand-delivery will require payment of an additional fee of $400 ($200 for small entities).  The only way to avoid paying this additional fee is by filing any non-provisional utility application via EFS-Web.  

Please see for more information about EFS-Web.  Full technical support for EFS-Web is available through the Patent Electronic Business Center (EBC) by calling  866-217-9197 from 6 a.m. to 12 midnight Eastern Standard Time (EST), Monday through Friday, except federal holidays.
