Rule 53.7

10.001.   What is international preliminary examination?  International preliminary examination of an international application may be requested under Chapter II of the PCT to obtain “a preliminary and non-binding opinion on the questions whether the claimed invention appears to be novel, to involve an inventive step (to be non-obvious), and to be industrially applicable” (Article 33(1)).  It is carried out by an “International Preliminary Examining Authority” at the request – called “demand” – of the applicant, for use before the “elected” Offices, that is, the designated Offices which are elected by the applicant for that purpose, (note that the filing of a demand constitutes the election of all Contracting States which are designated and bound by Chapter II of the Treaty).  Not every applicant who has the right to file an international application has the right to demand international preliminary examination;  the following paragraphs explain who may make a demand.
