The eleventh session of the PCT Working Group took place from June 18 to June 22, 2018. The meeting documents and the Summary, prepared by the Chair of the Meeting, as well as the report are now available. 

Meeting of International Authorities (MIA)

The 26th session of the Meeting of International Authorities took place from February 13 to February 14, 2019 in Cairo, Egypt, and the meeting documents and the summary by the Chair of the meeting are available.

PCT Assembly

The 50th session of the Assembly of the PCT Union (PCT Assembly) was held in Geneva during the period from 24 September to 2 October 2018 as part of the meetings of the Assemblies of the Member States of WIPO.  The PCT Assembly inter alia adopted amendments to PCT Rule 69.1(a) allowing the International Preliminary Examining Authority to start international preliminary examination once it is in possession of:

  • the demand for international preliminary examination;
  • the relevant fees;
  • either the international search report or the declaration by the International Searching Authority under PCT Article 17(2)(a); and
  • the written opinion established under PCT Rule 43bis.1

unless the applicant expressly requests to postpone the start of the international preliminary examination until the expiration of the applicable time limit under PCT Rule 54bis.1(a), thus reversing the default position so that, instead of waiting until the time limit for making the demand expires, examination should start immediately, unless the applicant expressly requests otherwise. 

For a complete summary, see the PCT Newsletter, October 2018.  All documents for this session are available as well as the report.

PCT-Patent Prosecution Highway Pilot (PCT-PPH)

PCT-PPH pathways enable applicants to request a fast track examination procedure.

  • 50 per cent of overall PPH is PCT-PPH.
  • Data from selected Offices in 2015 shows that PPH requests have a 7.5% to 26% higher grant rate and a 4% to 39.7% higher first Office action allowance rate than all applications combined. The average pendency rate from the PPH request to final decision was between 5.8 and 26.8 months less than for all applications combined:  consult PCT Yearly Review 2016 PDF,C.6; for the 2017 EPO PCT-PPH data:  Yearly Review 2018 PDF, C26

Learn the PCT video series

A series of 29 short videos (approximately 15 minutes each) presented by Matthias Reischle-Park, Deputy Director, PCT Legal and User Relations Division, WIPO [YouTube] (also available Portuguese-subtitled version prepared by INPI Brazil and Arabic-subtitled version prepared by the Saudi Patent Office). This series is:

  • 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.

Introductory PCT Distance learning course

The DL101PCT 4 hours course provides an introduction and general overview of PCT; it is complemented with self-assessment tools that are strategically placed throughout the course to measure understanding and progress and it is available in ten languages.

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.

In‑house seminars on the PCT with WIPO’s participation are available; for seminars open to the public consult the PCT Seminar Calendar.

Supplementary International Search

Requesting one or more supplementary international searches (SIS), during the PCT procedure, expands both the linguistic and technical scope of the search PPT

  • SIS addresses PCT applicants’ concerns about new prior art being found once they have already incurred significant costs and 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.

The PATENTSCOPE search engine

  • PATENTSCOPE offers free access to over 3,5 million PCT applications in addition to 74 million patent documents.
  • Contains the national patent data collections of 57 national or regional patent Offices.
  • The interface features a number of powerful tools, including cross-lingual and chemical compound (including substructures) searches as well as machine translation
  • Information on national phase processing of PCT applications is now available for 66 Offices.  Global Dossier public information is available for 5 Offices.
  • The redesigned version of the Patent Register Portal contains legal status information for over 200 national and regional collections, including a search functionality by PCT application number.
