    Does the Office send notifications via e-mail in respect of international applications?
    No
    Would the Office accept evidence of mailing a document, in case of loss or delay, where a delivery service other than the postal authorities is used (PCT Rule 82.1)?
    Yes, provided that the delivery service is:Chronopost, DHL, Federal Express, Flexpress, SkyNet, TNT, Transworld, UPS
    Does the Office excuse delays in meeting time limits due to the unavailability of electronic means of communication (PCT Rule 82quater.2(a))?
    For the relevant notification by the Office refer to the Official Notices (PCT Gazette) dated 26 November 2020, pages 254 et seq. and Notice from the EPO dated 22 October 2020 concerning the procedures and safeguards which apply under the EPC and the PCT in the event of outages of means of electronic filing and other online services (OJ EPO 2020, A120).Yes, delays in meeting time limits could be excused where any of the permitted means of electronic filing at the EPO notified under Rule 89bis, or means of online payment, was unavailable for a minimum of a continuous four-hour period on a specific working day. Rule 82quater.2 will not be applied by the EPO if a means of electronic filing is unavailable for less than four hours and an announcement of the outage has been published at least two working days in advance. In cases where the advance notice indicated that an outage was to last for less than four hours, but eventually lasted longer, the EPO will consider applying Rule 82quater.2. An unplanned outage, however, does not necessarily have to last a minimum of four hours to qualify for the application of Rule 82quater.2 by the EPO. If the unavailability of a means of electronic communication, or means of online payment, is qualified as an outage by its technical services, the EPO will consider applying Rule 82quater.2

    Annex L - Deposits of Microorganisms and Other Biological Material

    Requirements of designated and elected Offices
    Only Offices whose applicable national law contains provisions concerning the deposits of microorganisms and other biological material are listed in Annex L. Unless otherwise indicated, deposits may be made for the purposes of patent procedure before these Offices with any depositary institution having acquired the status of international depositary authority under the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure.For a list of these institutions refer to:https://www.wipo.int/documents/d/treaties/docs-en-registration-budapest-idalist.pdf (and the detailed requirements for each institution at: https://www.wipo.int/en/web/budapest-system/guide/section_d/subsection_cNotifications related thereto may be consulted under:https://www.wipo.int/en/web/treaties/registration/budapest/indexFurther information concerning the requirements of international depository authorities under the Budapest Treaty is available at:https://www.wipo.int/en/web/budapest-system/guide/index
    Time (if any) earlier than 16 months from priority date by which applicant must furnish:
    — the indications prescribed in Rule 13bis.3(a)(i) to (iii):
    None
    — any additional indications:
    At the time of filing
    Additional indications (if any) which must be given besides those prescribed in Rule 13bis.3(a)(i) to (iii) pursuant to notifications from the Office:
    To the extent available to the applicant, relevant information on the characteristics of the biological material
    Additional information
    Deposits with CNCM can be made under the Budapest Treaty or, as far as the deposits of cell cultures, mycoplasma and rickettsiae are concerned, under a bilateral agreement with the EPO.If the applicant wishes that, until the publication of the mention of the grant of a European patent or for 20 years from the date of filing if the application is refused or withdrawn or deemed to be withdrawn, the biological material shall be made available as provided in Rule 33(1) EPC only by the issue of a sample to an expert nominated by the requester (Rule 32(1) EPC), the applicant must, by a written statement, inform the International Bureau accordingly before completion of technical preparations for publication of the international application where such publication takes place in one of the EPO official languages (English, French or German). Such statement must be separate from the description and the claims of the international application and must preferably be made on Form PCT/RO/134, referred to in Section 209 of the Administrative Instructions under the PCT and available on the WIPO website at https://www.wipo.int/documents/d/pct-system/docs-en-forms-ro-editable-ed-ro134.pdf .If the international application was not published in an official language of the EPO (English, French, German), the statement under Rule 32(1) EPC can still be submitted in the European phase until completion of the technical preparations for publication of the translation of the international application under Article 153(4) EPC. The fact that the expert option has been chosen will then be published on the front page of the published translation of the application. Information received under Rule 32(1) EPC after completion of the technical preparations for publication of the international application – or, where applicable, of the translation of the application pursuant to Article 153(4) EPC – cannot be taken into account with the consequence that the biological material will be available to any person as provided for in PCT Rule 13bis.6 and Rule 33(1) EPC without an expert acting as intermediary (refer to Notice from the European Patent Office dated 7 July 2010 concerning inventions which involve the use of or concern biological material, OJ EPO 10/2010, page 498 et seq.).WARNING: Where the invention involves the use of or concerns biological material which is not available to the public at the date of filing the application and which has been deposited by a person other than the applicant, the reference to such a deposit must include the name and address of the depositor and a statement that the latter has authorized the applicant to refer to the deposited biological material in the application and has given his unreserved and irrevocable consent to the deposited material being made available to the public in accordance with Rule 31(1)(d) of the European Patent Convention (EPC). If any of these indications (the name and address of the depositor, and the statement) is not included in a reference to deposited biological material in the international application as filed, it may still be furnished to the International Bureau within a period of 16 months after the date of filing of the international patent application or, if priority is claimed, after the priority date; this time limit is deemed to have been met if the indication reaches the International Bureau before the technical preparations for international publication have been completed (PCT Rule 13bis.4(a)). Where the applicant makes a request for early publication under PCT Article 21(2)(b), the indications must be furnished to the International Bureau at the latest before the completion of the technical preparations for international publication (PCT Rule 13bis.4(c)). The failure to meet this time limit cannot be remedied upon entry into the European phase neither by re-establishment of rights nor by further processing. As a result, the application may have to be refused under Article 97(2) EPC in the course of examination proceedings for insufficient disclosure (Article 83 EPC).

The language of proceedings cannot be changed subsequently.EPC Rule 3(1), EPC Rule 3(2)In written proceedings, the applicant may use any official language of the EPO. However, amendments (refer to paragraph EP.18) to the application itself must be filed in the language of the proceedings.
    EP.03 TRANSLATION OF THE APPLICATION
    EPC Art. 153(4), EPC Rule 159(1)(a), EPC GL, A-XIII, 3, PCT Article 19(1), PCT Rule 49.3, PCT Rule 70.16, PCT Rule 74(1)If the Euro-PCT application was not published by the International Bureau in an official language of the EPO (English, French, German), the applicant must, within the 31-month time limit, submit to the EPO a translation of the application into one of the official languages (Form 1200, Section 7). Within the time limit of 31 months from the priority date (or the filing date if no priority is claimed), the applicant must furnish a translation of the description, the claims and any text in the drawings as originally filed, and the abstract as published. If the original drawings were filed in color or greyscale and are available in this form on PATENTSCOPE, and the international publication mentions this, any drawings in translations may contain color or greyscale only to the extent as in the original drawings, and the color content must exactly correspond to the original drawings.In addition, the following elements should also be included:if the EPO acts as designated Office:— any amendments made to the claims under PCT Article 19 in the form of a translation of the complete set of claims furnished in replacement of all claims originally filed only if the applicant wishes such amendments to form the basis of further proceedings. The amendments must be submitted together with, if submitted to the International Bureau, the statement under PCT Article 19(1) explaining the amendments and, in every case, the accompanying letter under PCT Rule 46.5(b) in an official language of the EPO. If a translation of the complete set of claims submitted under PCT Article 19 is not furnished or not accompanied by a translation of, if submitted to the International Bureau, the statement under PCT Article 19(1) and, in every case, the accompanying letter under PCT Rule 46.5(b), the amendments under PCT Article 19 will be disregarded for the further proceedings. If only the statement under PCT Article 19(1) is not available in an official language, only that document will be disregarded;— any indication under PCT Rule 13bis.3 and 13bis.4, i.e., separately furnished reference to deposited biological material;— any nucleotide and amino acid sequence listing under PCT Rule 5.2(a), unless the text in the sequence listing is available to the EPO in English;— any request for rectification referred to in PCT Rule 91.3(d) as published in accordance with PCT Rule 48.2(a)(vii).if the EPO acts as elected Office:— translation of any annexes to the international preliminary report on patentability (Chapter II), i.e. regardless of whether protection is sought for the same version of the application documents as was the subject of that report. If any amendments under PCT Article 19 are annexed to the IPRP (Chapter II), a translation of those amendments must also always be filed.If the applicant wishes the amendments to the claims made before the IB under PCT Article 19 to form the basis of the procedure before the EPO as elected Office, and these amendments are not annexed to the IPRP (Chapter II) (for instance because they were considered reversed by an amendment under PCT Article 34), then these amendments must also be furnished in translated form, as otherwise they will be disregarded for the further proceedings. Any statement under PCT Article 19(1) and, in every case, the letter under Rule PCT 46.5(b) must also be furnished in an official language of the EPO. If only the statement under PCT Article 19(1) is not available in an official language, only that document will be disregarded.If the translation of all annexes to the IPRP (Chapter II) is not filed in due time, the applicant is invited to furnish the missing translation within two months of notification of a communication. If the applicant fails to comply, the Euro-PCT application is deemed to be withdrawn. The applicant may request further processing (or re-establishment of rights under PCT Rule 49.6 if the application is deemed withdrawn because the translation was not filed in due time. However, the fee is higher and stricter requirements apply. Therefore, this remedy has only advantages if the period for requesting further processing has already expired).

    EPC Rule 38(2), RFees Art. 2(1).1a, OJ EPO 2009-338As a general rule, the page fee is based on the international application as published, regardless of the language of publication. The pages of the description, claims and drawings are counted, plus one page in total for any pages with the bibliographic data and the abstract. Amended claims under PCT Article 19 and/or PCT Article 34 are also considered part of the international publication and must be taken into account unless the applicant has indicated that the procedure in the European phase is not to be based on them. If (parts of) the description and/or claims are amended on entry into the European phase, the amended pages of the description and the amended set of claims replace the equivalent pages of the international application as published and, consequently, form then the basis for calculating the page fee.However, the calculation of the page fee cannot be based on pages of the description or of the claims drafted partly in an official language of the EPO and partly in another language. Thus, special rules for calculating the page fee apply if the international application was not published in one of the official languages of the EPO and amendments are filed upon entry into the European phase. Detailed information regarding the correct calculation of the page fee in such case is provided in OJ EPO 2009-338 and in the Guidelines for Examination in the EPO, A-III, 13.2. Completion of section 6 of EPO Form 1200 and the related table serves applicants to clearly indicate to the EPO the documents on which the further proceedings are to be based and to correctly compute the page fee.Pages with amendments filed after expiry of the 31-month time limit are not taken into account in calculating the page fee. Furthermore, page fees will not be refunded if the number of pages is reduced during the proceedings before the EPO.
    EP.06 EUROPEAN DESIGNATION FEE
    EPC Art. 79(2), EPC Rule 159(1)(d), EPC Rule 160, EPC Rule 39(1), RFees Art. 2 No. 3A (flat) designation fee must be paid within six months from the publication by the International Bureau of the international search report or before the expiration of the time limit applicable under PCT Articles 22(3) and 39(1)(b) and EPC Rule 159 (31 months from the filing date or, if priority has been claimed, the earliest priority date), whichever time limit expires later. If the designation fee is not paid in due time, the Euro-PCT application will be deemed withdrawn.
    EP.07 EXTENSION/VALIDATION
    OJ EPO 2009-603, OJ EPO 2015-A18-20, OJ EPO 2015-A84, OJ EPO 2015-A85, OJ EPO 2016-A5, OJ EPO 2016-A67, OJ EPO 2017-A85, OJ EPO 2018-A16, OJ EPO 2023, A105, OJ EPO 2025, A22International applications entering into the national phase at the EPO (European phase) can be extended to or validated in certain States which have concluded an Extension or Validation Agreement to that effect with the European Patent Organisation (they are indicated in the Summary), provided the Extension/Validation Agreement with the EPO was in force at the international filing date, the State concerned was designated for a national patent in the international application and the respective extension/validation fees have been paid, the amount of which is indicated in Annex EP.I. For payment of the extension/validation fee, the provisions for payment of the European designation fees apply mutatis mutandis. The request for extension/validation for a state is deemed withdrawn if the extension/validation fee is not paid to the EPO within the time limit laid down in the EPC for the payment of the designation fee (EPC Rule 159(1)(d) and EPC Rule 39(1), refer to paragraph EP.06). If the designation fee was paid but none of the extension/validation fees, no communication pointing out the failure to observe the time limit for payment of the extension/validation fees is issued. However, the applicant may still pay an extension/validation fee after expiry of the (basic) time limit for payment of the designation fee and the extension/validation fees with a 50% surcharge within a grace period of two months as from expiry of the basic time limit. Furthermore, where in the absence of payment of the designation fee in due time further processing can be requested in respect of the designation fee, the applicant may within two months from notification of the communication of the loss of rights also pay the extension/validation fee(s) with a 50% surcharge (refer to Guidelines for Examination in the EPO, A-III, 12.2). When an extension or (European) validation State accedes to the EPC, the Extension/Validation Agreement remains applicable to international applications filed prior to the date of accession.
    EP.08 CLAIMS FEES
    EPC Rule 162If the application documents on which the European grant procedure is to be based contain more than fifteen claims, a claims fee is payable within the 31-month period in respect of the sixteenth and each subsequent claim. A higher claims fee is payable in respect of the 51st and each subsequent claim. The claims fees must be calculated on the basis of the number of claims specified to form the basis for the further proceedings on entry into the national phase (that is, where amendments have been filed, the claims as amended under PCT Article 19 or 34(2) or the claims as submitted by the applicant under PCT Article 28 or 41 upon entering the national phase), unless the applicant uses the opportunity to amend the claims in response to the communication pursuant to EPC Rules 161 and 162 referred to in paragraph EP.18, the claims thus amended being then used as the basis for calculation of the claims fee and for the further proceedings. Where the applicant fails to pay the correct amount of the claims fees within the 31-month time limit, the EPO will invite him to pay the missing amount within the non-extendable six-month time limit set in the communication under EPC Rules 161 and 162. Where the number of claims changes as a consequence of a later (further) amendment filed in response to the communication pursuant to Rules 161 and 162, that number is to be used as the basis for calculating the amount of the claims fees to be paid. Where a claim fee is not paid in due time, a noting of loss of rights (EPC Rule 112(1)) is issued, giving the applicant the opportunity to request further processing (EPC Article 121) by paying the missing claims fee(s) together with the applicable fee for further processing within a period of two months from notification of the communication. If not paid within that period, the claim(s) concerned shall be deemed to be abandoned. Features of a claim deemed to have been abandoned and which are not otherwise to be found in the description or drawings cannot subsequently be reintroduced into the application and, in particular, the claims.
    EP.09 DESIGNATION OF THE INVENTOR
    EPC Rule 163(1), EPC Rule 163(6), OJ EPO 2021-A12, OJ EPO 2021-A3A designation of inventor must only be filed upon entry into the European phase if within the 31-month time limit the inventor has not been designated or certain information, e.g. the country or place of residence, is missing. If not filed upon entry, the EPO will invite the applicant to file the missing information within two months from the notification of a communication under Rule 163(1) or (4) EPC. If the missing information is not furnished within the two-month time limit, the application is refused. For further details, refer to the form for such designation in Annex EP.III. Legalization is not required.
    EP.10 APPOINTMENT OF AN AGENT AND POWER OF ATTORNEY
    EPC Art. 133, EPC Art. 134, EPC Rule 152, EPC Rule 163(5), EPC Rule 163(6), OJ EPO 2024, A75, OJ EPO 2024, A77, OJ EPO 2025, A45, OJ EPO 2025, A47Natural and legal persons having either their residence or their principal place of business within the territory of one of the EPC contracting states may act on their own behalf in proceedings before the EPO (EPC Article 133(1)). Natural and legal persons not having either a residence or their principal place of business within the territory of one of the EPC contracting states must be represented by a professional representative and act through them in all proceedings established by the EPC (refer to the Summary, “Who can act as agent?”). In case of failure to appoint the required professional representative, the applicant will be invited by the EPO to do so within two months. If the deficiency is not corrected in due time, the application is refused. Nevertheless, the applicant may act on their own behalf within the 31-month time limit applicable under PCT Articles 22(3) and 39(1)(b) and EPC Rule 159(1). Under no circumstances, however, may the applicant act through the agent appointed during the international phase if the latter is not an agent entitled to practice before the EPO. Payments can be made by anybody. A power of attorney (“Authorisation” or “General Authorisation”, refer to samples given in Annexes EP.IV and EP.V, respectively), generally, need not be filed by an agent who is a professional representative entered on the list maintained by the EPO or a legal practitioner entitled to act as representative under EPC Art. 134(8). It is, however, necessary that they inform the EPO of their appointment. This applies even if the professional representative or legal practitioner was appointed for the international phase, unless they were at the same time also explicitly appointed for the European phase before the EPO acting as Receiving Office. Employees representing an applicant under EPC Article 133(3) who are not professional representatives or legal practitioners must always file a signed authorization or a reference to a general authorization already on file (for details, refer to the Decision of the President of the EPO dated 7 July 2025 on the signing and filing of authorizations, OJ EPO 2025, A45 and the Notices OJ EPO 2024, A77 and OJ EPO 2025, A47). Only where the EPO acted as receiving Office and the authorization expressly empowered the employee to act before the EPO in the national phase, is a new authorization not required. In the rare cases where a power of attorney is required, the EPO will invite the applicant or agent to file it within a period to be specified. If the authorization is not filed in due time, any procedural steps taken by the agent will be deemed not to have been taken.
    EP.11 RENEWAL FEES
    EPC Art. 86(1), EPC Art. 86(2), EPC Rule 159(1)(g), EPC Rule 51, OJ EPO 2018-A2, RFees Art. 2 No. 4, RFees Art. 2 No. 5They are payable for the third and each subsequent year following the international filing date. Payment must be made before the expiration of the month containing the anniversary of the international filing date. Payment can then still be made, together with a 50% surcharge for late payment, before the expiration of the sixth month after the month containing the anniversary of the international filing date. It is to be noted that a renewal fee which is due within the 31-month time limit applicable under PCT Articles 22(3) and 39(1)(b) can be paid without surcharge up to the expiration of the 31-month time limit. The renewal fee can still validly be paid within six months after the expiration of the 31-month time limit, subject to the payment of the 50% surcharge. If the renewal fee is not paid within the six-month period, the application is deemed to be withdrawn. The failure to meet the time limit for paying the renewal fee with surcharge may be remedied by filing a request for re-establishment of rights (EPC Article 122, EPC Rule 136). The amounts of the renewal fees are indicated in Annex EP.I. For the calculation of aggregate time limits, refer to OJ EPO 1993-229, point II-3. The renewal fee in respect of the third year may not be validly paid more than six months before it falls due. All other renewal fees may not be validly paid more than three months before they fall due.
    EP.12 REQUEST FOR EXAMINATION
    EPC Art. 94A European patent will be granted only if the substantive examination of the application shows it to meet the requirements of the EPC. Examination will only start upon explicit request. The request may be made by using the form referred to in paragraph EP.01 (refer to pre-crossed box 4.1 of EPO Form 1200, Annex EP.II). The request for examination is not deemed to be filed until after the examination fee has been paid.
    EP.13 TIME LIMIT FOR REQUESTING EXAMINATION
    EPC Rule 159(1)(f), EPC Rule 160(1), EPC Rule 70(1)Examination must be requested within six months from the publication by the International Bureau of the international search report or before the expiration of the time limit applicable under PCT Articles 22(3) and 39(1)(b) and EPC Rule 159(1) (31 months from the filing date or, if priority has been claimed, from the earliest priority date), whichever time limit expires later. If the request for examination is not filed or the examination fee (refer to paragraph EP.14) not paid in due time, the Euro-PCT application is deemed to be withdrawn.
    EP.14 FEE FOR EXAMINATION
    EPC Art. 94(1), RFees Art. 14(2)The request for examination is only effective if the examination fee has been paid. That fee must therefore be paid within the time limits set out in paragraph EP.13. The amount of the said fee is indicated in Annex EP.I.(i) It is reduced by 75% where an international preliminary report on patentability (Chapter II) has been established by the EPO. If the report was established on certain parts of the international application, the reduction is allowed only if examination is to be performed on subject matter covered by the report.EPC Art. 14(2), EPC Rule 7a(1), EPC Rule 7a(2), EPC Rule 7b(1), OJ EPO 2024, A8, RFees Art. 14(1)(ii) Furthermore, a 30% reduction in the examination fee is available to microenterprises, small and medium-sized enterprises, natural persons, non-profit organizations, universities or public research organizations having their residence or principal place of business in a EPC contracting state with an official language other than English, French or German if they file the request for examination in an official language of that state (“admissible non-EPO language”) and declare themselves to be entitled to do so (EPC Rule 7b(1)). The declaration may be made directly in EPO Form 1200 or using EPO Form 1011. Since the request for examination is only effective if the examination fee has been paid, the request for examination in an admissible non-EPO language may still be filed up until the examination fee is paid. If the request for examination in an admissible non-EPO language is filed subsequently, it must be accompanied by a translation of the request for examination in the procedural language. (Refer to Annex EP.II, EPO Form 1200, page 2, box 4).RFees Art. 11, OJ EPO 2013-153(iii) If the conditions for both reductions are fulfilled, the examination fee is first reduced by 75%. The 30% reduction is applied to the resulting total and not to the full fee. Therefore, the total reduction in relation to the full fee is 82.50%.OJ EPO 2016-A48, OJ EPO 2016-A49, RFees Art. 11(a), RFees Art. 11(b)The examination fee is refunded in full if the application is withdrawn, refused or deemed to be withdrawn before substantive examination has begun. Fifty percent of the examination fee is refunded if the application is withdrawn, refused or deemed to be withdrawn after the examining division has begun but before expiry of the time limit for replying to the first invitation under Article 94(3) EPC issued by the examining division, or if no such invitation has been issued, before the date of the communication under Rule 71(3) EPC.
    EP.14a FEE REDUCTIONS FOR MICROENTERPRISES, NATURAL PERSONS, NON-PROFIT ORGANISATIONS, UNIVERSITIES OR PUBLIC RESEARCH ORGANISATIONS
    The following fees shall be reduced by 30% where an applicant declares to be a microenterprise, natural person, non-profit organisation, university or public research organisation files a European patent application or, in respect of an international application, performs the acts referred to in Rule 159:
    (a) filing fee;
    (b) fee for a European or supplementary European search;
    (c) examination fee, and in addition the previously paid international search fee where the European Patent Office acted as International Searching Authority;
    (d) designation fee;
    (e) fee for grant;
    (f) renewal fees for the European patent application.    Refer to the Decision of the EPO’s Administrative Council dated 14 December 2023 (CA/D 16/23), OJ EPO 2024, A3 and the Notice from the EPO dated 15 January 2024 concerning fee-related support measures for small entities, OJ EPO 2024, A8.provided, the same applicant(s) has/have not filed five or more applications (EP or Euro-PCT) in the five preceding years (EPC Rule 7a(4)). If there are multiple applicants, each of them must fulfil the applicable eligibility criteria. The declaration under EPC Rule 7b(1) can be made directly in EPO Form 1200 or using EPO Form 1011.Refer to the Decision of the EPO’s Administrative Council dated 14 December 2023 (CA/D 16/23), OJ EPO 2024, A3 and the Notice from the EPO dated 15 January 2024 concerning fee-related support measures for small entities, OJ EPO 2024, A8.
    EP.15 CONSEQUENCES OF NON-FULFILMENT OF CERTAIN REQUIREMENTS
    EPC Art. 121, EPC Rule 135, EPC Rule 160EPC Rule 160 provides that if either the translation of the international application or the request for examination is not filed in due time or if the filing fee, including any additional fee for pages exceeding 35, the search fee, the examination fee or the designation fee is not paid in due time, the European patent application is deemed withdrawn. In these circumstances, the applicant will be informed of the deemed withdrawal and EPC Rule 112(2) shall apply. However, the loss of rights shall be deemed not to have occurred if, within two months of the EPO notification, further processing is requested by payment of the respective fee(s) for further processing and the omitted act is completed.If the applicant neither filed the request for examination nor paid the examination fee in due time, further processing must be requested in respect of both omissions, i.e. in respect of filing the request for examination and payment of the examination fee. It follows that the applicant must file the request for examination and pay the examination fee together with two fees for further processing: a flat fee for further processing in respect of the request for examination and 50% of the examination fee.
    EP.16a SUPPLEMENTARY EUROPEAN SEARCH
    EPC Art. 153(7), EPC Rule 161, EPC Rule 70(2), EPC Rule 70a(2)As a rule, a supplementary European search must be performed for each international application entering the European phase and a search fee must be paid.The supplementary European search will be based on the last set of (amended) claims available to the EPO on the date of expiry of the time limit set under EPC Rule 161(2). Thus, any amendment to the claims which has been filed up to that date will be taken into account (refer to paragraph EP.18).OJ EPO 2015-A94Where the request for examination was filed before transmittal of the supplementary European search report, which is usually the case, the EPO invites the applicant, after transmittal of the supplementary European search report, to indicate whether they wish to proceed further with the application before the EPO. The applicant may waive the right to receive such communication by informing the EPO thereof in due time.— If the applicant does not wish to proceed further, they may withdraw the application or they may simply refrain from answering the invitation within the time limit fixed in it and the application is deemed to be withdrawn. If the applicant wishes to proceed further, they must notify the EPO accordingly. They may, at the same time, respond to the supplementary European search report by filing amendments and/or comments on the application. The applicant is required to reply to a search opinion within the time limit set by the EPO in its communication under EPC Rule 70a(2) if the EPO has issued a negative written opinion (refer to Guidelines for Examination in the EPO, B-XI, 8 and EP.18).No supplementary European search performed:Dispensation applies and no search fee is to be paid if the international search report (or supplementary international search report) was established by the EPO. In this case the applicant will be invited to comment on the written opinion of the ISA or on the IPRP (Chapter II), or on the supplementary international search report and to correct, if appropriate, any deficiencies noted therein and to amend the application within six months from notification of the invitation (EPC Rule 161(1)); refer to Guidelines for Examination in the EPO, E-IX, 3.2 for more details.Applicable as from 1 July 2010 (refer to OJ EPO 12/2009, 594).Applicable as from 1 May 2011 (refer to OJ EPO 12/2010, 634).
    EP.16b SEARCH FEE
    If a supplementary European search report is to be established, the search fee must be paid within the 31-month time limit, and may be reduced as follows:OJ EPO 2024-A3by EUR 1,300 where the international search report was drawn up by the Austrian Patent Office, the Finnish Patent and Registration Office, the Nordic Patent Institute, the Spanish Patent and Trademark Office, the Swedish Intellectual Property Office (PRV), the Turkish Patent and Trademark Office (Turkpatent) or the Visegrad Patent Institute. This reduction also applies when a supplementary international search was established by the Austrian Patent Office, the Finnish Patent and Registration Office, the Nordic Patent Institute, the Swedish Intellectual Property Office (PRV), the Turkish Patent and Trademark Office (Turkpatent) or the Visegrad Patent Institute.OJ EPO 2025, A25If the application claims the priority of an earlier application for which a search was carried out by the EPO, (a part of) the fee paid for the supplementary European search may be refunded. The level of any refund depends on the type of the earlier search and the extent to which the EPO benefits from the earlier search report when carrying out the supplementary search.
    EP.17 NUCLEOTIDE AND AMINO ACID SEQUENCES
    EPC Rule 30, EPC Rule 163(3), OJ EPO 2021, A97, OJ EPO 2025, A64, OJ EPO 2025, A66If a Standard-compliant sequence listing is contained in the international application under PCT Rule 5.2, furnished to the EPO acting as ISA/SISA or IPEA under PCT Rule 13ter.1(a) or made accessible to the EPO by other means, the applicant does not have to submit the Standard-compliant sequence listing again on entry into the regional phase before the EPO as designated or elected Office.Where, however, a Standard-compliant sequence listing is not available to the EPO on the expiry of the period under Rule 159(1) EPC, the applicant will be invited to file a Standard-compliant sequence listing within a non-extendable period of two months from the invitation and to pay the late furnishing fee. Furthermore, the applicant must enclose, together with the late filed sequence listing, a declaration to the effect that the sequence listing does not extend beyond the content of the application as originally filed (refer to EPO Form 1200, Section 9.2). The sequence listing must not be submitted on paper or in PDF format. EPC Rule 30(2) and (3) and the Decision of the President of the European Patent Office dated 14 November 2025 on the filing of sequence listings (OJ EPO 2025, A64) are to be applied accordingly (refer to EPC Rule 163(3) in conjunction with Article 3 of the above-mentioned decision of the President).If any deficiencies are not remedied in due time after such an invitation – this also applies to the payment of the late furnishing fee – the application will be refused (EPC Rule 30(3)). The applicant may request further processing of the application under EPC Article 121 EPC. For international and European patent applications filed until 30 June 2022, WIPO Standard ST.25 is applicable.Refer to OJ EPO 6/2011, 372 and OJ EPO 11/2013, 542.For international and European patent applications filed on or after 1 July 2022, the applicable sequence listing standard is WIPO Standard ST.26 (refer to the Decision of the President of the EPO dated 14 November 2025 on the filing of sequence listings, OJ EPO 2025, A64 and the notices from the EPO dated 9 December 2021, OJ EPO 2021, A97 and 14 November 2025, OJ EPO 2025, A66).
    EP.18 AMENDMENT OF THE APPLICATION; TIME LIMITS
    EPC Rule 161(1), EPC Rule 161(2), OJ EPO 2010-634For the purpose of the procedure before the EPO as designated/elected Office the applicant may always file (voluntary) amendments within the 31-month time limit, and may file (further) amendments until expiry of the time limit set in the combined communication under EPC Rules 161 and 162. The applicant may also be required to file (mandatory) amendments to and/or comments on the application within the time limit set in the communication under EPC Rules 161 and 162. Whether or not a response is mandatory is clearly stated in the communication, its wording thus differing depending on the case (EPO Forms 1226AA, 1226BB or 1226CC).The communication under EPC Rules 161 and 162 is issued for each application promptly once the application has entered the European phase and on condition that the ISR is available to the EPO. This means that it is also issued if the applicant has already filed, with Form 1200 or thereafter, amendments and/or comments to form the basis for the procedure in the European phase. Pursuant to EPC Rules 161 and 162 the time limit set in the communication is six months. This time limit cannot be extended.OJ EPO 2015-A94In order to accelerate the grant procedure the applicant can waive their right to the Rule 161/162 communication by crossing the box in Section 12.2, first checkbox, of EPO Form 1200. The waiver will only be effective if any claims fees due for the set of claims indicated as the basis for the procedure in the European phase have been paid and any mandatory substantive response to the WO-ISA / the IPRP (Chapter II) / the SISR, established by the EPO, was filed on entry into the European phase.EPC Rule 70a(2), EPC Rule 70a(3), EPC Rule 137(3)After expiry of the six-month time limit further possibilities for amending the application are limited. If no supplementary European search is carried out, it is at the discretion of the examining division to allow amendments. If a supplementary European search is carried out, the applicant always has one further opportunity to submit amendments upon receipt of the report. Thus, after issuance of the supplementary European search report the applicant may, first of all, comment on both the report and the search opinion and file (voluntary) amendments to the description, claims and drawings within the period specified in the communication under EPC Rule 70a(2) for indicating whether they wish to proceed further with the application. Secondly, if any deficiencies are noted in the search opinion, the applicant will be required under EPC Rule 70a(2) to respond to the objections made. The application will be deemed withdrawn if the applicant does not submit a substantive reply to the communication under EPC Rule 70a(2) (“mandatory response”). The loss of rights can be remedied by requesting further processing. Amendments made thereafter require the consent of the examining division.EPC Art. 123(2)Amendments may under no circumstances go beyond the disclosure in the international application as filed.EPC Rule 137(4)Whenever amendments are filed, the applicant must identify them and indicate their basis in the application as filed. If they fail to do so, the examining division may issue a communication requesting correction of the omission within a non-extendable time limit of one month. If the deficiency is not remedied in due time, the application will be deemed withdrawn under EPC Article 94(4). The loss of rights can be remedied by requesting further processing.
    EP.19 GRANTING OF THE EUROPEAN PATENT
    EPC Art. 97(1), EPC Rule 71(3), EPC Rule 71(4), EPC Rule 71(5), EPC Rule 71(6)Prior to the decision to grant the European patent, the applicant will receive a communication containing both the text in which the Examining Division intends to grant the European patent and an invitation to pay the grant and printing fees and to supply a translation of the claims in the two other official languages of the EPO. Performance of these acts implies approval of the text. If applicable, the communication will also include an invitation to pay additional claims fees.
    EP.20 FEE FOR GRANT
    EPC Rule 71(3)The amounts of the fees are indicated in Annex EP.I. They must be paid within four months from the communication pursuant to EPC Rule 71(3) referred to in paragraph EP.19
    EP.21 TRANSLATION OF CLAIMS
    EPC Rule 71(3)Within the same period, the claims must be translated into the two official languages of the EPO which are not the language of proceedings (refer to paragraphs EP.02 and EP.19).
    EP.22 EARLY PROCESSING OF NATIONAL PHASE
    EPC Rule 159(1), PCT Article 23(2), PCT Article 40(2)If the applicant wishes the processing and the examination of the application to start earlier than the expiration of the time limit applicable under PCT Article 22(3) or 39(1)(b), they must file an express request for early processing. The request can be made by ticking the checkbox in section 12.1 of EPO Form 1200. Moreover, the applicant must fulfill the requirements for entry into the European phase as if the 31-month time limit provided for in EPC Rule 159(1) expired on the date they request early processing (refer to OJ EPO No. 3/2013-156 et seq.).
    EP.23 REVIEW UNDER ARTICLE 25 OF THE PCT
    PCT Article 25, PCT Rule 51, PCT Rule 82bis, EPC Rule 159(2)The applicable procedure is outlined in paragraphs NP 6.018 to NP 6.021 of the National Phase. At the request of the applicant, the EPO may review whether a refusal by the receiving Office to accord a filing date, or a declaration on the part of the receiving Office that a Euro-PCT application or the designation of a state is considered withdrawn, or a finding by the International Bureau under PCT Article 12(3) is the result of an error or omission on the part of the authority concerned, in which case the Euro-PCT application can proceed as a European application.To obtain such a review by the EPO as designated/elected Office, applicants must, within the two-month time limit under PCT Rule 51.1, request the International Bureau under PCT Article 25(1) to send copies of documents in the files promptly to the EPO as designated Office. Furthermore, the filing fee under EPC Rule 159(1)(c) must be paid and, where required, a translation of the Euro-PCT application furnished within the same two-month time limit (PCT Rule 51.3).Applicants are recommended to undertake the remaining steps for entry into the European phase under EPC Rule 159(1) at the same time.EPC Art. 106, EPC Art. 108If, upon review under PCT Article 25, the EPO denies an error or omission on the part of the receiving Office or the International Bureau, a notice of appeal against this decision may be lodged within two months from the date of receipt of the decision. Within the same two-month time limit, a fee for appeal must be paid (for the amount, refer to Annex EP.I). Within four months from the date of receipt of the decision, grounds substantiating the notice of appeal must be filed. The Board of Appeal will then decide on the appeal.
    EP.24 EXCUSE OF DELAYS IN MEETING TIME LIMITS
    PCT Article 24(2), PCT Article 48(2), PCT Rule 82bisReference is made to paragraphs NP 6.022 to NP 6.028 of the National Phase and to paragraph EP.15.
    EP.25 FURTHER PROCESSING
    PCT Rule 82bis.2, EPC Art. 121, EPC Rule 135Further processing of the application may be requested where the applicant has missed a time limit during the international or the national phase in respect of which further processing is not ruled out under Rule 135(2). If the request is granted, this has the effect that the legal consequence of the failure to observe the time limit is deemed not to have ensued. It must be made by completing the omitted act(s), as applicable, and payment of the fee(s) for further processing, the amount of which is indicated in Annex EP.I, within two months of the notification of the noting of loss of rights (EPC Rule 112(1)). The fee for further processing varies depending on whether the loss of rights occurred due to an omitted act (flat rate fee) or the late payment of a fee (50% of that fee). In some cases, both fees for further processing have to be paid, e.g. if further processing is requested for the late filing of the request for examination and the late payment of the examination fee (refer to paragraph EP.15).
    EP.26 RE-ESTABLISHMENT OF RIGHTS
    PCT Rule 82bis.2, EPC Art. 122, EPC Rule 136Re-establishment of rights may be requested where the applicant lost any right because, in spite of all due care required by the circumstances having been taken, they were unable to observe a time limit during the international or the national phase. An application for re-establishment must be filed in writing within two months from the removal of the cause of non-compliance with the time limit(s) but not later than one year from the expiration of the time limit(s) which have not been observed. Within the said two months, the omitted act(s) must be completed, the respective fee(s) for re-establishment of rights (refer to Annex EP.I) must be paid and the request must state the grounds on which it is based and must set out the facts on which it relies. However, re-establishment of rights is ruled out in respect of any period for which further processing under EPC Article 121 is available. Refer to Guidelines for Examination in the EPO, E-IX, 3 for more details.
    EP.27 PRIORITY DOCUMENTS
    EPC Rule 53(2), OJ EPO 2019-A27, OJ EPO 2021-A83Where the priority of an earlier application is claimed for a Euro-PCT application, the priority document is sent by the International Bureau to the EPO, if the International Bureau received the priority document from the receiving Office or directly from the applicant or was able to retrieve it from a digital library. The EPO will, at the request of the applicant, include free of charge in the file of the European patent application a copy of the previous application from which priority is claimed, if it can be retrieved via the WIPO Digital Access Service (DAS), using the indicated DAS access code. Where for any reason the priority document has not been submitted by the time of entry into the national phase, the applicant will be invited to furnish the missing document(s) within two months from the date of a notification under EPC Rule 163(2). This time limit cannot be extended. If the priority document or the application number is not submitted within that time limit, the priority right is lost. The loss of rights may be remedied by requesting further processing.EPC Rule 163(2), OJ EPO 2024, A88A priority document may be filed in electronic form with the EPO only if it is digitally signed by the issuing authority and the signature is accepted by the EPO. A priority document cannot be filed by the EPO Contingency Upload Service.No obligation to furnish the priority document:The EPO as designated/elected Office will include a copy of the priority document free of charge in the file of a Euro-PCT application even without having received a copy from the International Bureau if the priority application is:— a European patent application;— an international application filed with the EPO as receiving Office;EPC Rule 53(3)Where the language of priority documents is not one of the official languages of the EPO (English, French or German) and the validity of the priority claim is relevant to the determination of the patentability of the invention concerned, the applicant is invited to file, within the time limit specified by the EPO, a translation in one of these three languages or a declaration that the international application is a complete translation of the priority application. Failure to comply with this invitation will result in the loss of the right of the relevant priority. For further information refer to Guidelines for Examination in the EPO, A-III, 6.8.
    EP.28 RESTORATION OF PRIORITY
    EPC Art. 122, OJ EPO 2007-692, PCT Rule 49ter.1, PCT Rule 49ter.2If the international application was filed more than 12 months from the filing date of the earlier application whose priority is claimed, the applicant may file or resubmit a request for restoration of priority with the EPO as designated/elected Office.A request for restoration of the right of priority under PCT Rule 49ter.2 may be granted provided the following requirements are met:— the filing date is within two months from the date on which the priority period expired (PCT Rule 26bis.2(c)(iii));— the failure to claim the right of priority within the priority period occurred in spite of all due care required by the circumstances having been taken; thus, the requirement of due care is applied by the EPO in accordance with its standing practice under EPC Article 122;— the request for restoration of priority is filed within one month from the date on which the 31-month time limit for entry into the European phase expired (PCT Rule 49ter.2(b)(i)), or within one month from the receipt of a request for early processing (PCT Articles 23(2) or 40(2));— the fee for restoration of priority levied by the EPO is duly paid within the same time limit (PCT Rule 49ter.2(b)(iii));— the request for restoration of priority is accompanied by a statement of reasons for the failure and is preferably accompanied by any declaration or other evidence in support of the statement of reasons (PCT Rule 49ter.2(b)(ii)).
    EP.29 PROOF OF ENTITLEMENT TO CLAIM PIORITY
    EPC Art. 87(1)The applicant claiming the priority from a previous application must be the applicant of the latter or the successor in title to the applicant who filed the previous application. Where the previous application was filed by joint applicants, all of them must be among the later international or European patent application’s applicants or have transferred their rights in the priority application to the later patent application’s applicant. However, the EPC does not set out any formal requirements for the transfer of the priority right. Absent any substantiated indication to the contrary, there is a strong presumption under the EPC that an applicant or joint applicants claiming priority in accordance with EPC Art. 88(1) and EPC Rule 52 are entitled to the claimed priority. Where an international application under the PCT is filed by joint applicants, including the priority applicant, but without naming the priority applicant as applicant for the European designation, the mere fact of the joint filing implies an agreement between the applicants allowing all of them to rely on the priority right unless substantial facts indicate otherwise (Refer to G 1/22 and G 2/22).
    EP.30 LACK OF UNITY
    EPC Art. 82, EPC Rule 164, OJ EPO 2014-A70If upon expiry of the time limit set in the communication under EPC Rules 161 and 162 for filing amendments, the documents that serve as the basis for the supplementary European search or for examination contain claims relating to an invention that was not searched by the EPO, and the application documents do not meet the requirement of unity of invention, the procedure under EPC Rule 164 applies (refer to OJ EPO 2014-A70).The EPO did not act as (S)ISA:— In this case the EPO draws up a partial supplementary European search report on those parts of the application which relate to the invention first mentioned in the claims and informs the applicant that, for the supplementary European search report to cover the other inventions, a further search fee must be paid in respect of each invention involved, within two months.The EPO acted as (S)ISA:— Where the supplementary European search report is dispensed with (refer to EP.16a) and the examining division considers that in the application documents which are to serve as the basis for examination an invention is claimed which was not searched by the EPO as (S)ISA, the examining division shall inform the applicant that a search will be performed in respect of any such invention for which a search fee is paid within a period of two months.
    EP.31 INCORPORATION BY REFERENCE OF CORRECT ELEMENTS OR PARTS UNDER PCT RULE 20.5bis(d)
    OJ EPO 2020-A81, OJ EPO 2022, A71, PCT Rule 20.5bis(d), PCT Rule 20.8(b-bis)In the international phase, under PCT Rule 20.5bis(d), it is possible to incorporate by reference correct elements or parts into the application as originally filed without changing the international filing date, provided the requirements of PCT Rule 20.5bis(d) are fulfilled. However, where the international application was filed between 1 July 2020 and 31 October 2022 and the receiving Office has allowed the incorporation of correct elements or parts, such incorporation will not be effective before the EPO as designated or elected Office due to the incompatibility of PCT Rule 20.5bis(d) with the EPC (refer to “International Phase”, paragraph IP 6.027).In such cases, applicants may inform the EPO within the 31-month time limit under EPC Rule 159(1), or at the latest before a corresponding communication is issued, on the basis of which documents they wish to pursue the Euro-PCT application:a) on documents containing the correct elements or parts and with the filing date changed to the date of receipt of those elements or parts, orb) on the documents as originally filed and based on the initial filing date. In such case, the correct elements or parts incorporated by reference are disregarded.If no such information is present on entry into the European phase, the EPO will send a communication under PCT Rule 20.8(c) and Rule 82ter.1(c) and (d) to clarify the situation for the proceedings before the EPO as designated or elected Office.For international applications filed on or after 1 November 2022, the EPO will fully apply Rule 20.5bis PCT, so that incorporations by reference allowed by the receiving Office under Rule 20.5bis(d) PCT will also be effective before the EPO as designated or elected Office.
