How can I associate a previously filed international application with my customer number?

To associate a previously filed international application with your customer number, you need to submit a request to the USPTO. The request must include the following information:

• Your customer number
• The international application number
• Your registration number (if applicable)
• Signature of the applicant or attorney of record

You can use Form PTO-2248 for this purpose, which is available on the USPTO website. As stated in MPEP 1809: “Form PTO-2248 may be obtained from the USPTO website (www.uspto.gov/patents-getting-started/international-protection/patent-cooperation-treaty/pct-chapter-i-forms).”

You can submit the completed form by:

1. Mailing it to: Mail Stop EBC, Commissioner for Patents, P.O. Box 1450, Alexandria, VA 22313-1450
2. Faxing it to: 571-273-0177

Once processed, you’ll be able to view the status of your previously filed international application in Private PAIR.
