The following topics were considered by the Working Group during the eighteenth session. Electronic processing of international applications The Working Group agreed to submit amendments to Rules 4, 45bis, 92bis and 94 of the PCT Regulations for approval by the PCT Assembly at its session in July 2026, with the aim of improving electronic services and providing a higher degree of protection for personal data provided for PCT processing. The amendments will require the provision of an email address and a telephone number for processing an international application, allow the exclusion of certain personal data from public access, and provide a basis for changing the address to which correspondence is to be addressed later than 30 months from the priority date (refer to document PCT/WG/18/8 and Annex I to document PCT/WG/18/20). Establishing equivalent amounts of PCT fees The Working Group agreed to submit to the Assembly proposed modifications to Directives of the PCT Assembly relating to the Establishment of Equivalent Amounts of Certain Fees to streamline the process for establishing equivalent amounts and reduce the time between a fluctuation in an exchange rate and the entry into force of a new equivalent amount to reflect that fluctuation (refer to document PCT/WG/18/12 and Annex II to document PCT/WG/18/20). Proposal to transmit a copy of the notification of withdrawal (Form PCT/RO/136) to the applicant The Working Group approved, in principle, modifications to Section 326 of the Administrative Instructions and paragraph 322 of the PCT Receiving Office Guidelines which would provide a basis for receiving Offices that wish to do so, to inform the applicant of the processing status of a withdrawal request when the receiving Office transmits the notice effecting such withdrawal to the International Bureau (refer to document PCT/WG/18/10 and Annex III to document PCT/WG/18/20).

The session was suspended and will be resumed at a future date. Documents for the session are available at: https://www.wipo.int/meetings/en/details.jsp?meeting_id=89833 PCT Committee for Technical Cooperation The thirty-third session of the PCT Committee for Technical Cooperation was held in Geneva on 2 and 3 February 2026. The Committee discussed the application from the Mexican Institute of Industrial Property (IMPI) to be appointed as an International Searching Authority and International Preliminary Examining Authority (ISA/IPEA) under the PCT (see document PCT/CTC/33/27). The Committee also discussed the applications for extension of appointment of all 25 existing ISA/IPEAs, the periods of appointment of which will expire on 31 December 2027 (see documents PCT/CTC/33/2 to 26). The Committee agreed to recommend to the PCT Assembly the appointment of IMPI as an ISA/IPEA and the extension of appointment of all existing ISA/IPEAs. The Committee also approved a new format for the model agreement to be used as a basis for preparing the individual agreements that each Office or organization will have with the International Bureau in relation to its functioning as an ISA/IPEA from 1 January 2028. The new format for the agreement will no longer have separate annexes setting out the operational information for each ISA/IPEA; this information will be published in the Official Notices (PCT Gazette) and reflected in the PCT Applicant’s Guide. When approving the new format, the Committee agreed to submit to the Assembly amendments to the PCT Regulations necessary for use of the new format for the agreements (see document PCT/CTC/33/28). These amendments will be considered by the PCT Assembly in July 2026 when it decides on the appointment of IMPI and the extensions of appointment of existing ISA/IPEAs and, where appropriate, approves the individual draft agreements between each Office or organization and the International Bureau. The Summary by the Chair (document PCT/CTC/33/29) is available on the WIPO website with the working documents and a link to the webcast videos and speech-to-text transcripts of the session at: https://www.wipo.int/meetings/en/details.jsp?meeting_id=89830

| February|PCT User Survey reveals high satisfaction levels The PCT continues to offer a strong, consistent and highly valued service, according to WIPO’s most recent PCT user satisfaction survey, carried out in late 2025. Overall, 90% of respondents said they were either “very satisfied” (44%) or “satisfied” (46%) with the PCT-related services provided by WIPO – in line with previous survey results from 2023 and 2021, and a slight increase on the 88% satisfaction rating in 2019. The survey is conducted every two years as part of WIPO’s ongoing efforts to monitor and continuously improve customer satisfaction. The latest survey was made available in all 10 PCT publication languages during the final quarter of 2025 and received more than 1,700 responses. Respondents were invited to rate a range of services such as processing of PCT applications by the International Bureau (IB) (including in its capacity as receiving Office), ePCT functions and services, PCT information resources and training provided by WIPO. They also had the opportunity to provide text comments and suggest areas for possible improvement. The IB is analyzing the survey feedback in detail with a view to further improving PCT services, and PCT users are as always also welcome to send comments and suggestions at any time to: pct.legal@wipo.int A summary of the survey results is available at: https://www.wipo.int/documents/d/pct-system/docs-en-activity-pct-user-survey-2025.pdf Technology diffusion under the spotlight in World IP Report 2026 New research from WIPO sheds light on the critical factors that help turn new inventions into widely adopted, impactful innovations. The World Intellectual Property Report 2026: Technology on the Move draws on 250 years of historical data on technology use and five decades of patent data to explore changing patterns of technology diffusion. The report finds that new innovations are spreading much more rapidly than innovation in previous eras. The time between the invention of new technologies and their first use worldwide is shrinking, and the technology use gap between advanced economies and others is narrowing for more recent technologies – especially digital technologies. But while technologies are spreading across borders faster than ever, there remain many challenges in making technology diffusion work in developing economies and coordinated policy action is required to realize the full potential of new technologies.

| February|PATENTSCOPE introduces verified SEP searches WIPO has enhanced its global patent database, PATENTSCOPE, with the addition of a new feature allowing users to search for verified standard essential patents (SEPs). The latest enhancement builds on “Declared SEPs” functionality introduced in 2025 which already enabled searches for patents that patentholders have declared as being potentially essential to a technical standard. The new feature takes that initiative a step further by identifying patents that have been objectively verified as SEPs by independent experts on behalf of a patent pool administrator. The first patent pool administrator to provide verified essentiality data is Sisvel. WIPO is engaging with stakeholders to further expand verified data sources. More information is available at: https://www.wipo.int/en/web/patents/w/news/2026/patentscope-introduces-verified-sep- searches-announces-upcoming-user-webinars PCT Patent Prosecution Highway (PCT-PPH) pilots ARIPO joins Global PPH pilot On 6 January 2026, the African Regional Intellectual Property Organization (ARIPO) joined the Global Patent Prosecution Highway (GPPH) pilot, bringing the number of Offices taking part in the pilot to 29. The GPPH makes it possible to request accelerated processing at any participating Office, based on work products (including, where applicable, a PCT written opinion from either the ISA or the IPEA, or an international preliminary report on patentability (IPRP) (Chapter II)) from any one of the other participating Offices, provided that at least one claim has been found to be patentable by the Office of earlier examination, and that any other applicable eligibility criteria are met. The pilot uses a single set of qualifying requirements and aims to simplify and improve the existing PPH network to make it more accessible to users. Further information about the GPPH pilot can be found at: https://www.jpo.go.jp/e/toppage/pph-portal/globalpph.html The PCT-PPH page of the PCT website has been updated at: https://www.wipo.int/pct/en/filing/pct_pph.html WIPO Digital Access Service for Priority Documents Under the Digital Access Service for Priority Documents (DAS), a PCT applicant can request the International Bureau (IB) to retrieve a copy of an earlier application from DAS for use as a priority document, instead of providing or arranging for the provision of a certified copy. Note that, in order to be able to make use of the DAS service, the Office with which the earlier application was filed needs to be a DAS depositing Office – not necessarily the receiving Office with which the international application is filed.

The time limit to file the demand is about to expire. Is it possible to obtain more time to submit the amendments if they are not ready? A: International preliminary examination is an optional procedure that provides the only possibility during the international phase for an applicant to amend the description, claims and drawings of an international application. This possibility is provided by PCT Article 34, which also provides the right for an applicant to communicate orally and in writing with the International Preliminary Examining Authority (IPEA). The examiner at the IPEA will therefore be able to consider amendments and arguments submitted by the applicant, and this may give the applicant further opportunities to make amendments, as provided by PCT Rules 66.3 and 66.4, before the IPEA establishes the international preliminary examination report. By contrast, without filing a demand for international preliminary examination, an applicant has only one opportunity to amend the claims of an international application before the International Bureau under PCT Article 19, where the amended claims are published but not considered during the international phase. International preliminary examination is often referred to as the procedure under Chapter II, as it is governed by Chapter II of the PCT. The time limit to file a demand for international preliminary examination is either (i) three months from the date of the transmittal of the international search report (ISR) and the written opinion by the International Searching Authority (ISA) or (ii) 22 months from the priority date, whichever expires later (PCT Rule 54bis.1(a)). Generally, the IPEA may start international preliminary examination as soon as it is in possession of the demand, the fees due, the ISR and the written opinion of the ISA, provided that any translation required under PCT Rule 55.2 has been furnished. It is therefore advisable to file the demand and pay the applicable fees as soon as possible after you receive the results of the international search since the earlier the examination starts, the more time you will have to communicate with the examiner before the IPEA must establish its report. It is generally recommended to submit amendments and any arguments at the same time as filing the demand, noting that the IPEA need not take into account any amendments or arguments which it receives after it has begun to draw up its own written opinion or the report under PCT Rule 66.4bis). If your amendments are not ready when the time limit under PCT Rule 54bis.1(a) to file a demand is about to expire, and you wish the international preliminary examination to start on the basis of the amendments, it is important to ensure that at least the demand is filed within the

_ February_time limit. You should indicate in the demand that you wish the international preliminary examination to start on the basis of the description, claims or drawings as amended under PCT Article 34 (Box No. IV of Form PCT/IPEA/401). If no such amendments have in fact been submitted, the IPEA will invite you to submit them within a time limit fixed in the invitation (PCT Rule 60.1(g)) (using Form PCT/IPEA/431). The IPEA will not start examination before it has received the amendments, or before the time limit fixed in the invitation has expired (PCT Rules 60.1(g) and 69.1(e)). Please note that as this will delay the start of the examination, you may have less time to communicate with the examiner, noting that the IPEA must still establish the report within the time limit of PCT Rule 69.2, that is (where any required translation has been furnished together with the demand), 28 months from the priority date or 6 months from the start of the examination, whichever expires last. Further information can be found in the Practical Advice in the following issues of the 3&71HZVOHWWHU: – 03/2005: Time limit for submitting a formal response to a written opinion of the ISA where a demand for international preliminary examination is being filed – 06/2019: The timing of the start of the international preliminary examination (following the amendment to PCT Rule 69.1(a)) The demand may be submitted via ePCT to the International Bureau, which will transmit it to the competent IPEA in accordance with PCT Article 31(6)(a) and Rule 59.3. In this case, the demand will be considered to have been received by the competent IPEA on the date of receipt by the International Bureau.

| February|PCT Fee TablesThe following Tables show the amounts and currencies of the main PCT fees which are payable to the receiving Offices (ROs) and the International Preliminary Examining Authorities (IPEAs) during the international phase under Chapter I (Tables I(a) and I(b)) and under Chapter II (Table II). Fees which are payable only in particular circumstances are not shown; nor are details of certain reductions and refunds which may be available; such information can be found in the PCT Applicant’s Guide, Annexes C, D and E. Note that all amounts are subject to change due to variations in the fees themselves or fluctuations in exchange rates. The international filing fee may be reduced by CHF 100, 200 or 300 where the international application, or part of the international application, is filed in electronic form, as prescribed under Item 4(a), (b) and (c) of the Schedule of Fees (annexed to the Regulations under the PCT) and the PCT Applicant’s Guide, paragraph 5.189. A 90% reduction in the international filing fee (including the fee per sheet over 30), the supplementary search handling fee and the handling fee, as well as an exemption from the transmittal fee payable to the International Bureau as receiving Office, is also available to applicants from certain States—refer to footnotes 2 and 14. (Note that if the CHF 100, 200 or 300 reduction, as the case may be, and the 90% reduction are applicable, the 90% reduction is calculated after the CHF 100, 200 or 300 reduction.) The footnotes to the Fee Tables follow Table II.
