On August 3, 2019, the USPTO announced:
"If you are a foreign-domiciled trademark applicant, registrant, or party to Trademark Trial and Appeal Board proceedings, in all U.S. trademark matters you must now be represented by an attorney who is licensed to practice law in the United States. This includes Canadian applicants, registrants, and parties.
In addition to this change, U.S.-licensed attorneys representing anyone before the USPTO in trademark matters are now required to confirm they are an active member in good standing of their bar and to provide their bar membership information.
Learn more about this federal trademark law change."
