Before you apply


To file a Patent Cooperation Treaty (PCT) application at least one applicant or inventor must be a national or resident of a country that is a member of the PCT (a 'contracting state').

Australia is a PCT contracting state and we are the receiving office for PCT applications made by Australian nationals or residents.

An up-to-date list of contracting states is available on the World Intellectual Property Organization (WIPO) website.
