  • designed to provide a basic introduction to important aspects and issues in the international phase and national phase of PCT processing; and
  • closely follows material covered during basic PCT training seminars and will be particularly useful for those who have not attended such seminars in person, for small and medium-sized enterprises, and for PCT users and potential users in developing and least-developed countries.

PCT Webinars

  • PCT Webinars are used to deliver PCT information, training and updates in ten languages free of charge; recorded webinars are available at PCT Webinars.

  • SIS addresses PCT applicants’ concerns about new prior art being found once they have already entered the national phase and provides extra information in cases where the applicant believes that the commercial value of an invention warrants the additional expense in the international phase.
  • Get an introduction into SIS by a short video Video or the relevant part of the Applicant’s Guide.

The WIPO Digital Access Service (DAS) is an electronic system allowing priority documents and similar documents to be securely exchanged between participating intellectual property (IP) offices, including for PCT purposes (further information). DAS is generally free of charge and simplifies providing priority documents previously exchanged by paper. Many Offices joined DAS recently (consult WIPO DAS News).
