You are required to have a U.S.-licensed attorney represent you in trademark matters at theUSPTO if your domicile is not located in the United States or its territories. A person’sdomicile is the place the person resides and intends to be the person’s principal home. Abusiness’s domicile is the location of its headquarters where the entity’s senior executives orofficers ordinarily direct and control the entity’s activities and is usually the center from where other locations are controlled.
Only an attorney who is an active member in good standing of the bar of the highest court of any U.S. state (including the District of Columbia or any Commonwealth or territory of the U.S.) can represent you in a trademark matter at the USPTO. Foreign attorneys who are not licensed to practice law in the U.S. and non-attorneys cannot represent you (including preparing, signing, or filing submissions for you) in a trademark matter at the USPTO.
Once you hire an attorney, the USPTO will only communicate with your attorney about your application, registration, or TTAB proceeding.
