The U.S. Patent and Trademark Office (USPTO) has updated the Rules of Practice in Patent Cases to require patent applicants and patent owners whose domicile is not located within the U.S. or its territories to be represented by a registered patent practitioner. This rule change is effective on July 20, 2026.
When representation is required, papers submitted to the USPTO must be signed by a registered patent practitioner. The new requirement applies to all papers received in patent matters on or after July 20, 2026, regardless of the filing date of the application.
