International PCT applications

carte Etats membres du PCT.jpg


P&TS is qualified to file international patent applications under the PCT. A draft is prepared by a P&TS patent agent on the basis of spoken or written indications provided by the applicant. This draft is submitted to the applicant who can correct and/or complete it before filing.

Patent Cooperation Treaty (PCT)
There currently is no "international patent". The Patent Cooperation Treaty (PCT) has however instituted an international application which produces in each of the designated states the same effects as a national application. The PCT has been ratified by 144 Member States (status May 2012) including most of the industrialized countries. It is thus possible to file a single international application, in one language, to replace over hundred national applications.
The list of member states is available for instance on the site of the World Intellectual Property Organization (WIPO) under http://www.wipo.int/pct/guide/en/gdvol1/annexes/annexa/ax_a.pdf
The PCT is administered by the World Intellectual Property Organization (WIPO) in Geneva (Switzerland). The grant procedure however involves the collaboration of different patent offices, in various capacities and depending notably on the applicant 's nationality or domicile.
