PCT recent and future developments

New PCT Contracting State: 

Cambodia (country code:  KH)

On 8 September 2016, Cambodia deposited its instrument of accession to the PCT, thus becoming the 151st Contracting State of the PCT, and on 8 December 2016, will become bound by the PCT.  Consequently, any international application filed on or after 8 December 2016 will automatically include the designation of Cambodia.  Also, because Cambodia will be bound by Chapter II of the PCT, it will automatically be elected in any demand filed in respect of an international application filed on or after 8 December 2016. 

Furthermore, nationals and residents of Cambodia will be entitled, as from 8 December 2016, to file international applications under the PCT.

PCT Filings in 2015

International patent applications grew by 1.7% to 218,000 in 2015, setting a new annual record. Innovators based in the United States have filed the largest annual number of international patent applications for 38 years running. Still, large increases in patent-filing activity by China-based innovators accounted for much of the overall growth.

The top 5 countries of origin for the year were:

  • United States (57,385)
  • Japan (44,235)
  • China (29,846)
  • Germany (18,072)
  • Republic of Korea (14,626)

Assembly of the PCT Union

The 48th session of the Assembly of the PCT Union (PCT Assembly) was held in Geneva from 3 to 11 October 2016, as part of the meetings of the Assemblies of the Member States of WIPO.  The PCT Assembly, inter alia:

  • Adopted a number of amendments to the PCT Regulations to extend the deadline for requesting supplementary international search from 19 to 22 months from the priority date, to further add a further small change to Rule 23bis and to remove unnecessary incompatibility provisions (see PCT/A/48/3);
  • Appointed Turkish Patent Institute as an International Searching Authority (ISA) and International Preliminary Examining Authority (IPEA) under the PCT. The appointment will become effective from a future date to be notified by the Office when it is ready to begin operations. (see PCT/A/48/4).

For a complete summary, see the PCT Newsletter, October 2016.  All documents for this session are now available and the report shall be available shortly.

Learn the PCT video series

Learn the PCT is a series of 29 short videos (approximately 15 minutes each) presented by Matthias Reischle, Deputy Director, PCT Legal Division, WIPO [YouTube] (see also portuguese-subtitled version prepared by INPI Brazil). This series is:

  • designed to provide a basic introduction to important aspects and issues in the international phase and national phase of PCT processing;
  • 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.

Collaborative search and examination: third pilot started in 2016

In reply to industry’s request for a single search report and written opinion presenting the views of the examiners of multiple patent offices, the EPO, KIPO and USPTO have completed a second pilot project that examined:

  • how collaboration between examiners could be implemented in an operational environment; and
  • the benefits and disadvantages of the collaborative approach in terms of quality and efficiency.

See also the report on the second pilot in document  PCT/MIA/20/4 PDF and the views of the EPO participants in document PCT/WG/5/9 PDF as well as updates in PCT/WG/6/22 PDF and PCT/WG/7/20 PDF.

The third pilot started on 1 June 2016 and is expected to run for three years (see document PCT/MIA/23/12 PDF).

PCT-Patent Prosecution Highway Pilot (PCT-PPH)

  • 112 individual PCT-PPH pathways are now in place enabling applicants to request a fast track examination procedure.
  • 50 per cent of overall PPH is PCT-PPH.

The PATENTSCOPE search engine


WIPO GREEN is a platform that matches owners of environmentally sound technologies (ESTs) with those seeking licensing or partnership agreements. Listing your ESTs in the WIPO GREEN platform is free of charge and offers a practical additional means for seeking potential licensees or partners.

WIPO Arbitration & Mediation Center

Gives 25% reduction in the registration and administration fees for its alternative dispute resolution (ADR) services where at least one party to the dispute has been named as an applicant or inventor in a published PCT application (PCT Newsletter, June 2012, page 8 PDF).

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.
