Patent Cooperation Treaty Update
                              Accession by Uganda

  The United States Patent and Trademark Office received notification from
the World Intellectual Property Organization (WIPO) that Uganda deposited
its instrument of accession to the Patent Cooperation Treaty (PCT) on
November 9, 1994. Uganda will become the 75th Contracting State of the PCT
on February 9, 1995. Consequently, nationals and residents of Uganda are
entitled to file international applications under the PCT on and after
February 9, 1995, and from the same date it is possible to file
international applications designating and electing Uganda (country code:
UG).
              Designation for an ARIPO Patent will include Uganda


  The African Regional Industrial Property Organization (ARIPO) has 14
member States, 11 of which are party to the Harare Protocol on Patents and
Industrial Designs. The Harare Protocol makes it possible to obtain an
ARIPO patent effective in any or all of the Protocol's member States.
Under amendments to the Harare Protocol and its Implementing Regulations
adopted in April 1994, an international application under the PCT will be
able to include a designation for an ARIPO patent (two-letter code: AP) of
those Harare Protocol member States which are also Contracting States of
the PCT. Processing of such international applications in the regional
phase will be undertaken by the ARIPO office as a designated (or elected)
Office under the PCT. Since Uganda is a member of the Harare Protocol
within the framework of ARIPO, Uganda will be able to be designated for a
patent granted by ARIPO. As of February 9, 1995, any designation in an
international application for an ARIPO patent will automatically include
the designation of Uganda for that purpose.

                            Accession by Singapore

  The United States Patent and Trademark Office received notification from
WIPO that Singapore deposited its instrument of accession to the PCT on
November 23, 1994. Singapore will become the 76th Contracting State of the
PCT on February 23, 1995. Consequently, nationals and residents of
Singapore are entitled to file international applications under the PCT on
and after February 23, 1995, and from the same date it is possible to file
international applications designating and electing Singapore (county
code: SG).
