This rule becomes effective on August 3.
The requirement applies to all trademark applicants, registrants, and parties whose permanent legal residence or principal place of business is outside the United States, including Canadian applicants, registrants, and parties. These applicants, registrants, and parties are required to have a U.S.-licensed attorney represent them at the USPTO in all trademark matters.
In addition to this change, U.S.-licensed attorneys representing anyone before the USPTO in trademark matters are required to confirm they are an active member in good standing of their bar and to provide their bar membership information.
