How can I submit a patent term extension application?

Patent term extension applications can be submitted in two ways:

  • By mail addressed to Mail Stop Hatch-Waxman PTE, Commissioner for Patents, P.O. Box 1450, Alexandria, Virginia 22313-1450
  • Hand-carried to the Office of Patent Legal Administration

It’s important to note that “Patent term extension applications MUST NOT be filed by facsimile or the Office’s electronic filing system (EFS-Web).” However, related correspondence such as change of address can be sent by facsimile or via EFS-Web.

Applicants are encouraged to use the post card receipt practice described in MPEP § 502 for confirmation of receipt.
