Every patentee not residing in the United States may file in the
Patent and Trademark Office a written designation stating the name
and address of a person residing within the United States on whom
may be served process or notice of proceedings affecting the patent
or rights thereunder. If the person designated cannot be found at
the address given in the last designation, or if no person has been
designated, the United States District Court for the District of
Columbia shall have jurisdiction and summons shall be served by
publication or otherwise as the court directs. The court shall have
the same jurisdiction to take any action respecting the patent or
rights thereunder that it would have if the patentee were
personally within the jurisdiction of the court.
