Is a certified copy of the priority application required at time of filing?
No, a certified copy of any priority application(s) is not required to be submitted to the United States Patent and Trademark Office. However, the Applicant is required to submit a certified copy of the corresponding registration which issues from such priority application(s) in order to prefect the priority claim. Please note that if the U.S. trademark application is otherwise in a condition for publication, further prosecution of the application will be suspended until the necessary certified copy of the corresponding registration(s) is submitted to the United States Patent and Trademark Office. Alternatively, if the trademark application also claims one or more additional bases for registration, e.g., an Intent to Use the mark, Use, etc., the claim to the foreign application may be canceled, if desired.
