PCT Highlights

The International Patent System

PCT recent and future developments

New PCT Contracting State

Jamaica (country code:  JM)

On 10 November 2021, Jamaica deposited its instrument of accession to the PCT, thus becoming the 154th Contracting State of the PCT, and on 10 February 2022, will become bound by the PCT.  Consequently, any international application filed on or after 10 February 2022 will automatically include the designation of Jamaica.  Also, because Jamaica 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 10 February 2022. 

Accession to Paris Convention

Kiribati (country code:  KI)

On 5 November 2021, deposited its instrument of accession to the Paris Convention and from 5 February 2022 Kiribati will be bound by the Paris Convention, thus bringing the total number of States party to that Convention to 178.  Thus, under PCT Rule 4.10(a), it will be possible from that date to claim in an international application the priority of one or more earlier applications filed in Kiribati.

Regional Patent Treaties: ARIPO

Seychelles (country code: SC)

On 1 October 2021, Seychelles deposited its instrument of accession to the Harare Protocol on Patents and Industrial Designs within the Framework of the African Regional Intellectual Property Organization (ARIPO).  Therefore, with effect from 1 January 2022, the Harare Protocol entered into force with respect to Seychelles. This means that any international application filed on or after 1 January 2022 includes the designation of Seychelles for an ARIPO patent, as well as for a national patent. 

PCT Assembly

The fifty-third (23rd ordinary) session of the PCT Assembly took place from 4 to 8 October 2021. The Assembly adopted amendments to the PCT Regulations (document PCT/A/53/3). 

The amendments consist of the following:

  • PCT Rules 5, 12, 13ter, 19 and 49: Implementing WIPO Standard ST.26 “Recommended Standard for the Presentation of Nucleotide and Amino Acid Sequence Listings using XML (eXtensible Markup Language)” in the PCT.  These amendments will enter into force on 1 July 2022 and will apply to any international application with an international filing date on or after that date. 
  • PCT Rule 82quater: Strengthening safeguards for applicants and third parties in case of general disruption that affect meeting time limits under the Regulations (document PCT/WG/14/11).  These amendments will also enter into force on 1 July 2022 and apply to any time limit that expires on or after that date.

The Assembly also appointed the Eurasian Patent Office as an International Searching and Preliminary Examining Authority under the PCT (document PCT/A/53/1). The appointment will become effective from a future date to be notified by the Office when it is ready to begin operations.

For further information, please consult the PCT Newsletter 10/2021 PDF and the meeting documents.

Implementation Date of WIPO Standard ST.26: 1 July 2022

The 54th session of the WIPO General Assembly approved the implementation date of WIPO Standard ST.26 “Recommended Standard for the Presentation of Nucleotide and Amino Acid Sequence Listings using XML (eXtensible Markup Language)” at national, regional and international levels of 1 July 2022. The transition to WIPO Standard ST.26 will therefore take place six months after the date previously decided by the Committee of WIPO Standards at its fifth session in 2017.

      • Requesting one or more supplementary international searches (SIS), during the international phase procedure, expands both the linguistic and technical scope of the search
      • 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 PATENTSCOPE database


      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).
