notification from the World Intellectual Property Organization (WIPO)
that the Lao People's Democratic Republic, on March 14, 2006, and
Honduras, on March 20, 2006, have deposited their instruments of

designation of the Lao People's Democratic Republic (country code: LA),
and any international application filed on or after June 20, 2006 will
automatically include the designation of Honduras (country code: HN).

to file international applications under the PCT. Also, because the Lao
People's Democratic Republic and Honduras will be bound by Chapter II
of the PCT, they will automatically be elected in any demand filed in
respect of an international application filed on or after June 14 and
20, 2006, respectively. The Lao People's Democratic Republic has made a
declaration under PCT Article 64(5).
