As Of August 2019 U.S. Licensed Lawyers Required For Trademark Matters Before The USPTO

Effective August 3, 2019, the United States Patent and Trademark Office will require all non-U.S. trademark applicants, non-U.S. trademark registrants, and non-U.S. parties to a trademark proceeding to be represented by a U.S. licensed lawyer.  The USPTO will correspond only with the appointed U.S. licensed attorney.  
Canadian trademark attorneys and agents will continue, if eligible, to be recognized as additionally appointed practitioners who can represent their Canadian clients.  But, as with other non-U.S. licensed lawyers, the USPTO will correspond only with the appointed U.S. licensed attorney.
