Draft once, file anywhere

Depending on your requirements, you can file PCT applications using either WIPO's PCT-SAFE software or the EPO's Online Filing software.

Working in close co-operation with the Trilateral Offices (EPO, JPO and USPTO), on 7 January 2002 WIPO issued modified Administrative Instructions under the Patent Cooperation Treaty (PCT) (addition of Part 7 and Annex F) to establish the legal framework and the technical standard required to implement the electronic filing and processing of international applications under the PCT and at the same time to pave the way for a PCT version of Online Filing (E-PCT), with a view to creating compatible systems allowing the online filing of PCT applications.

On 1 November 2002, the EPO expanded its Online Services to enable PCT electronic filing for European applicants wishing to use the EPO as receiving Office. This software also allows the filing of EP and Euro-PCT applications.

In the same month, WIPO started pilot testing its PCT-SAFE system for electronic filing under the PCT. With the International Bureau as receiving Office, the system was launched for pilot programme users on 25 August 2003 and for all PCT applicants on 12 February 2004.

As a result of this co-operation between the Trilateral Offices and WIPO, users can now file applications with different receiving Offices, using compatible software (such as the EPO's Online Filing software or WIPO's PCT-SAFE).
