Where should I send a petition to restore the benefit of a provisional application?

According to the MPEP, a petition to restore the benefit of a provisional application should be addressed to:

“Mail Stop Petition, Commissioner for Patents, P.O. Box 1450, Alexandria, Virginia 22313-1450.”

It’s important to note that this petition must be filed in the subsequent nonprovisional application or international application designating the United States, not in the provisional application itself. Always ensure you’re following the most current USPTO guidelines for petition submissions, as procedures may be updated over time.
