Is designating a domestic representative mandatory for foreign patent assignees?
While designating a domestic representative is not mandatory, it is highly recommended for foreign patent assignees. According to MPEP 302.04, An assignee of a patent or patent application who is not domiciled in the United States may, by written document signed by such assignee, designate a domestic representative.
The use of ‘may’ indicates that this is optional. However, having a domestic representative can significantly simplify legal proceedings and communications with the USPTO for foreign assignees.
