Patent Cooperation Treaty (PCT)
(1) International search shall be carried out by an International Searching Authority, which may be either a national Office or an intergovernmental organization, such as the International Patent Institute, whose tasks include the establishing of documentary search reports on prior art with respect to inventions which are the subject of applications.
(2) If, pending the establishment of a single International Searching Authority, there are several International Searching Authorities, each receiving Office shall, in accordance with the provisions of the applicable agreement referred to in paragraph (3)(b), specify the International Searching Authority or Authorities competent for the searching of international applications filed with such Office.
(3)(a) International Searching Authorities shall be appointed by the Assembly. Any national Office and any intergovernmental organization satisfying the requirements referred to in subparagraph (c) may be appointed as International Searching Authority.
(b) Appointment shall be conditional on the consent of the national Office or intergovernmental organization to be appointed and the conclusion of an agreement, subject to approval by the Assembly, between such Office or organization and the International Bureau. The agreement shall specify the rights and obligations of the parties, in particular, the formal undertaking by the said Office or organization to apply and observe all the common rules of international search.
(c) The Regulations prescribe the minimum requirements, particularly as to manpower and documentation, which any Office or organization must satisfy before it can be appointed and must continue to satisfy while it remains appointed.
(e) Before the Assembly makes a decision on the appointment of any national Office or intergovernmental organization, or on the extension of its appointment, or before it allows any such appointment to lapse, the Assembly shall hear the interested Office or organization and seek the advice of the Committee for Technical Cooperation referred to in Article 56 once that Committee has been established.
