PCT Article 31

Demand for International Preliminary Examination


  • (4)
    • (a) The demand shall indicate the Contracting State or States in which the applicant intends to use the results of the international preliminary examination ("elected States"). Additional Contracting States may be elected later. Election may relate only to Contracting States already designated under Article 4.
    • (b) Applicants referred to in paragraph (2)(a) may elect any Contracting State bound by Chapter II. Applicants referred to in paragraph (2)(b) may elect only such Contracting States bound by Chapter II as have declared that they are prepared to be elected by such applicants.


The filing of a demand shall constitute the election of all Contracting States which are designated and are bound by Chapter II of the Treaty on the international filing date (PCT Rule 53.7 ). For demands filed before January 1, 2004, only those eligible states pursuant to PCT Article 31 indicated as being elected are elected. Only PCT member states which have ratified or acceded to Chapter II and which were designated in the Request may be elected under Chapter II. The Assembly has taken no action to allow persons who are residents or nationals of a State not party to the PCT or not bound by Chapter II to make a Demand under Article 31(2)(b).
