The maximum term of a European patent is 20 years from its filing date. The patent may lapse earlier if the annual renewal fees are not paid or if the patent is revoked by the patentee or after opposition proceedings. In certain cases (medical or plant protection product patents) it is possible to extend the period of protection.
Yes, in two ways:
In proceedings before the European Patent Office, following publication of a European patent application, any person may submit observations concerning the patentability of the invention to which that application or the granted patent relates. These observations must be filed in writing in English, French or German and must include a statement of the grounds on which they are based. There are no fees for presenting such observations. We advise using the official EPO web-based filing form, which has been designed to help you to formulate your observations in a structured and concise manner; it is available free of charge from the EPO website (tpo.epo.org). Filing observations does not make you a party to any official proceedings the EPO undertakes, and you will not be informed by the EPO about the further outcome of the patent grant proceedings. However, it is important to note that submissions filed as third-party observations will be placed in the public part of the file of the patent application or patent and will thus be accessible to the public. The observations are communicated to the patent applicant/proprietor, who may comment on them.
For further details please see:
We advise using the official EPO opposition form (2300), which is available free of charge from the EPO and the central industrial property offices of the contracting states. Notice of opposition is not deemed to have been filed until the opposition fee of EUR 775 has been paid.
For further details of the opposition procedure see the Guide for applicants, Part 1, point 178 ff.
Requests for the grant of a European patent must be filed on the form prescribed by the European Patent Office (EPO Form 1001). This should be accompanied (where applicable - i.e. where the applicant is not the inventor or is not the sole inventor) by a "Designation of the inventor" form (EPO Form 1002). An "Authorisation" (EPO Form 1003) may also be required (see "Representation" below).
European patent applications must contain:
If you do not have either a residence or a place of business within the territory of an EPC contracting state (non-resident applicants) you must be represented by a professional representative and act through him in all proceedings, other than in filing the European patent application. You can find a professional representative in the database of professional representatives.
Cost of a European patent application
The following fees are payable upon filing a European patent application.
In the case of a divisional application filed in respect of any earlier application which is itself a divisional application (Rule 38, paragraph 4)
The above fees are due within one month of filing the European patent application.
Further fees are due if you decide that you wish to pursue the application after receiving the European search report.
Where to file
Our filing offices are located in Munich, Berlin and The Hague. You may also file by fax or online.
The EPO's postal addresses and fax numbers can be found on the Contact page.
For further information on how to file a European patent application and on the European patent grant procedure, see How to get a European patent, Guide for applicants, Part 1, as well as the EPO forms required and the current Schedule of fees and expenses.
The European patent grant procedure takes about three to five years from the date your application is filed. It is made up of two main stages. The first comprises a formalities examination, the preparation of the search report and the preliminary opinion on whether the claimed invention and the application meet the requirements of the EPC. The second involves substantive examination.
The European and national patent grant procedures exist in parallel. When seeking patent protection in one or more EPC contracting states, you can choose either to follow the national procedure in each state or to take the European route, which confers protection in all the contracting states that you designate in a single procedure.
If you want to patent your invention in one particular country, you will need to contact the national patent office of the country concerned.
If you decide that you want a European patent, you have the choice between the direct European route and the Euro-PCT route. With the direct European route, the entire procedure is governed by the EPC alone. With the Euro-PCT route, the first phase of the grant procedure (the international phase) is subject to the PCT (Patent Cooperation Treaty), while the regional phase before the EPO as designated or elected Office is governed primarily by the EPC.
For further details see the Guide for applicants, Part 1 and the Guide for applicants, Part 2 (Euro-PCT).
If you want to patent your invention in a specific country only, you should contact the national patent office of the country concerned.
In order to initiate the European phase you must fulfil certain minimum requirements within 31 months of the filing date or, if priority has been claimed, the earliest priority date. More details can be found in the Guide for applicants, Part 2 (Euro-PCT), point 449 ff.
Yes. If you or your predecessor in title have filed an application for either a patent or the registration of a utility model or a utility certificate in or for any state party to the Paris Convention for the Protection of Industrial Property (176 states) or any member of the World Trade Organization (160 states), you may claim priority when filing a European patent application in respect of the same invention. You should do so no later than 12 months after filing the first application.
If the previous application was filed in or for an EPC contracting state, you may also designate that state in the European application. The previous application whose priority you claim may also be a European or international (PCT) application.
For further details see the Guide for applicants, Part 1, point 52 ff.
If you have either a residence or a place of business within the territory of an EPC contracting state you are not obliged to be represented by a professional representative (European patent attorney). If you are a non-resident applicant, you may file a European patent application on your own behalf but must appoint a professional representative and act through him afterwards. This does not apply to fee payments, since these may be made by anybody.
Patent grant procedures are highly complex. So if you lack the requisite experience, we advise you to consult a professional representative before the EPO.
Representation may also be undertaken by any legal practitioner qualified in one of the contracting states and having his place of business within that state, provided that he is entitled in that state to act as a professional representative in patent matters.
Further details can be found in the Guide for applicants, Part 1, point 58 ff.
Fees are charged for filing (including, if applicable, an additional fee for the 36th and each subsequent page), search, designation of contracting states, claims (if more than fifteen), examination, grant and printing. Renewal fees are also payable for the third year and each subsequent year after the date of filing.
The filing and search fees due at the beginning of the procedure currently amount to about EUR 1 495 (or EUR 1 405 if the application is filed online). The remaining fees are payable later. That means that applicants can decide at each stage of the procedure whether or not to continue with their application. As a rough guide, it currently costs on average EUR 5 655 (or EUR 5 565 if the application is filed online) to take a patent application through to the grant stage.
At the post-grant stage, competence is transferred to the contracting states designated in the European patent. In some contracting states, costs may be incurred for validation of the European patent there. In order to maintain the patent, renewal fees must be paid in each designated state. The amount of the renewal fee varies from state to state.
The overall cost of obtaining a European patent may also include fees for the services of a patent attorney. Further details of these costs can be obtained from any patent attorney authorised to act as a professional representative before the EPO. A searchable database of professional representatives is available on this website.
No, the EPO does not provide any assistance with licensing, funding, or finding venture-capital partners. Helpful websites can be found in our useful links collection.
Fees due to the EPO may be paid by payment or transfer to a bank account held by the EPO.
They may also be paid by debiting a deposit account opened with the EPO in Munich (Supplementary publication 4, OJ EPO 2014, "Arrangements for deposit accounts (ADA) and their annexes").
Holders of EPO deposit accounts may also use the EPO's Online Fee Payment service.
Credit card payments are not accepted.
All fees must be paid in euros; payments in other currencies will not be accepted.
Please note that the use of EPO Form 1010 or PCT Form PCT/RO/101 or IPEA/401 for filing debit orders became mandatory on 1 April 2014.
Fees may be validly paid to the EPO by any person.
Beware of fake invoices from firms and individuals requesting the payment of fees for the registration or publication of a patent application. Check the payment subject and bank account number on the invoice and compare it against the EPO’s bank account on our Making payments page and list of fees and expenses at www.epo.org/fees.
Visit www.epo.org/warning for further information and examples and who to contact if you have any doubts about the legitimacy of an invitation or invoice.
The bank closures in Greece are an exceptional occurrence, beyond applicants’ control, for which Rule 134(5) EPC provides a safeguard.
In the case of any applicants, other parties or their representatives residing or having their place of business in Greece who offer evidence, in writing, that
the time limit for paying a fee will be deemed to have been observed even though the payment is received late.
For payments falling due for international applications, Rule 82quater.1 PCT is applicable.
For more information, please see the notice of the President of the EPO dated 3 July 2015.
If you have a query about your search report, please contact us by letter or fax quoting the application number. We cannot give this information out over the phone.
Your application will be published 18 months after the filing date or the earliest priority date. You may, however, request that it be published earlier.
For further details see the Guide for applicants, Part 1, point 149 ff.
Requests to change the address of the applicant or inventor should be submitted in writing (letter or fax) to the EPO's official address, quoting the application number(s) concerned. Where appropriate, you can indicate that the change of address affects all applications filed in your company's name. There is no fee payable and no prescribed form is required.
European patent applications have to designate the inventor. If the applicant is not the inventor or is not the sole inventor, the designation must contain a statement indicating the origin of the right to the European patent. Unless he waives this right in due time, the person designated as the inventor will be mentioned in the published European patent application, the European patent specification, the European Patent Register and the European Patent Bulletin.
Incorrect designations may be rectified provided that a request is received, accompanied by the consent of the wrongly designated person and the consent of the applicant for or proprietor of the patent where the request is not filed by that party. If an additional inventor is to be designated, the consent of the inventor(s) previously designated is not necessary. You can request rectification after the proceedings before the EPO are terminated.
Where an incorrect designation has been rectified after publication, the rectification or cancellation will also be published in the European Patent Register or European Patent Bulletin. The national patent offices will be informed accordingly. However, a new patent certificate/specification will not be issued by the EPO since the inventor was not known at the date of grant.
An administrative fee of EUR 100 (code 023) per application must be paid.
Note: The last date that a licence can be recorded with the EPO is the day before the mention of the grant in the European Patent Bulletin. Any request must therefore be filed before that date.
Where a patent has been granted but no request filed in due time, licences must be recorded with the competent national office(s), in accordance with the relevant national regulations.
Registrations of transfers (assignments) of European patent applications are recorded in the European Patent Register at the request of an interested party and on production of documents satisfying the EPO that the transfer has taken place. This might be a copy of or extract from an official document, or a declaration signed by both parties.
There is no prescribed form for such requests. They must, however, be filed in writing with the EPO, quoting the application number(s) concerned.
You will have to pay an administrative fee of EUR 100 per application (fee code 022).
Further details can be found in the Guidelines for Examination in the EPO, Part E, Chapter XII, point 1.
If the change affects the name only, and no transfer of rights has occurred, you can ask for it to be recorded by sending a letter or fax to the EPO quoting the relevant application number. No fee is payable. Furthermore, formal documentary proof of the change of name, e.g. a certificate of marriage, an extract from the commercial register (showing old and new name) or any other official document, certified by a Notary Public, must be submitted.

Yes, waiving the right to the communication under Rules 161 and 162 EPC and fulfilling the requirements of those rules upon entry into the European phase will speed up the formalities checks. These would otherwise be performed only upon expiry of the six-month time limit under Rules 161 and 162 EPC, and the file would only then be transferred to the search or examining division.
To accelerate the processing of your application you can request accelerated search or examination under the PACE programme. However, if you do so, but do not validly waive your right to receive the communication under Rules 161 and 162 EPC, the application will not be subject to accelerated search or examination until after a communication under Rules 161 and 162 EPC is issued and after expiry of the six-month time limit provided for under those rules.
It follows that the waiver option and PACE concern different stages of the proceedings and are not interrelated.
Yes, if you are using the automatic debiting procedure and waive your right to the communication under Rules 161 and 162 EPC, you must pay any claims fees due on entry into the European phase by another permitted means since, under the automatic debiting procedure, claims fees are considered to have been received on the last day of the six-month period under Rule 162(2) EPC.
You can ask the EPO as designated or elected Office to start processing a Euro-PCT application any time before expiry of the 31-month time limit calculated from the international date of filing or from the priority date, if priority is claimed, regardless of whether the international application has been published. To do this, you must file an express request for early processing (preferably referring to Article 23(2) or, where applicable, to Article 40(2) PCT). Please note that such a request is not provided for in EPO Form 1200. Furthermore, you must fulfil the requirements for entry into the European phase as if the 31-month time limit mentioned above had expired on the date of your request.
Please note that your request is effective once the EPO receives it, provided that all the necessary requirements are met. From then on the application will be processed in the same way as any Euro-PCT application that has entered the European phase, and you have the option of filing a divisional application.
The fees for early processing should not be paid by automatic debit order. This is because they would be debited, and thus paid, on the last day of the 31-month time limit under Rule 159(1) EPC, so the EPO could not start processing the application until that time limit had expired.
The new version of Rule 36 EPC will apply to divisional applications filed on or after 1 April 2014. The Administrative Council's decision removing the current time limits for filing divisional applications does not provide for any transitional provisions. Thus when the amendment of Rule 36 EPC enters into force on 1 April 2014, a divisional application may be filed in respect of any earlier application still pending. This also applies to cases where the time limits applicable between 1 April 2010 and 31 March 2014 have already expired.
We would also like to point out that there will be an additional fee as part of the filing fee for divisional applications of second and subsequent generations. Detailed information will be published on the EPO website.
You will be sent EPO Form 2532G "Noting of loss of rights pursuant to Rule 112(1) EPC".
This loss of rights can be remedied during examination proceedings by filing either a request for further processing under Article 121 and Rule 135 EPC or a request for decision under Rule 112(2) EPC.
Please note that where translations of more than one priority document are requested and not provided in time, a further processing fee is due for each of the priorities concerned.
If documents replacing parts of the application or patent specification documents in opposition proceedings are submitted with handwritten amendments, they will be considered formally deficient, and the applicant will be given the opportunity to correct the formal deficiency within two months.
For more detailed information please refer to the new practice of the EPO’s first-instance departments on the application of Rules 49 and 50 EPC with respect to handwritten amendments – frequently asked questions.
The new fees are applicable as from 1 April 2014 and are binding on payments made on or after 1 April 2014. A link to the updated schedule of fees can be found at the bottom of this answer.
Fees must be paid in EUR direct to the EPO. You can do this by paying them into or transferring them to a bank account held by the EPO or by debiting a deposit account you have opened with the EPO via a debit order. If you are an EPO deposit account holder, you also have the option of issuing an automatic debit order. For debit orders submitted online, you can defer execution dates. The fees will then be debited from the deposit account at a later date of your choice.
Depending on how you pay, the deemed date of payment is the day on which (a) the amount of the payment or transfer is actually credited to a bank account held by the Office or (b) the order to debit a deposit account is received at the EPO, provided the deposit account contains sufficient funds.
Please note that the use of EPO Form 1010 or PCT Form PCT/RO/101 or IPEA/401 for filing debit orders became mandatory on 1 April 2014.
For more detailed information on this issue please refer to the following documents:
If you pay the fees under Rule 71(3)-(4) EPC and file the translations under Rule 71(3) EPC you are deemed to have approved the text communicated to you under Rule 71(3) EPC and to have verified the bibliographic data in that communication.
Once you have approved it, the text forms the basis for the decision to grant a European patent, and will be published in this form. That is why it is important that you should check it first.
According to decision G1/10 of the Enlarged Board of Appeal, where an applicant does not, where necessary, request reasoned amendments or corrections to the communicated text before it is approved, the responsibility for any errors remaining in that text after grant are his alone (G1/10 of the Enlarged Board of Appeal of 23 July 2012 (OJ EPO 2013, 194, point 11 of the reasons).
No. Once the intention to grant has been communicated and the text has been approved by the applicant, the EPO cannot make any further changes, even if the request for correction is submitted before the text is published. In decisions of the EPO, only linguistic errors, errors of transcription and obvious mistakes may be corrected.
For printing errors (errors in publication) see “What can I do if the text of the patent specification as published is not the one I approved?”
If a decision to grant contains an error made after the text has been approved by the patent proprietor (e.g. if the examining division erroneously changes the wording of a claim), such that the text as granted is not that approved by the proprietor, then the patent proprietor is adversely affected by that decision and is entitled to appeal (G 1/10, point 12 of the reasons).
Such errors must be distinguished from printing errors/errors in publication. Printing errors are errors that occur in the publication process. If such errors occur, the content of the printed specification will differ from that of the documents (Druckexemplar) transmitted to the applicant with the communication under Rule 71(3) (EPO Form 2004) and approved by him.
Printing errors/errors in publication can be corrected at any time.
Yes, a European patent application may indeed be filed in any language. However, if the language is not one of the EPO’s official languages (English, French or German) you need to file a translation in one of the official languages within two months of filing the application. If the translation is not filed in due time, the EPO will invite you to correct this deficiency within two months. The official language into which the application is translated constitutes the language of the proceedings and cannot be changed at a later stage. Please note that if you fail to file the translation in due time in reply to the EPO’s invitation, the application will be deemed withdrawn. In such a case you may request re-establishment of rights under Article 122 EPC.
If the examining division is of the opinion that the application and the invention to which it relates meet the requirements of the European Patent Convention, it will proceed to the grant of the European patent. At this point the applicant is invited to pay the fee for grant and publishing and to file translations of the claims in the two other official languages.
Finally, after the grant of the European patent, a validation procedure - often including translation of the patent specification and/or claims - may have to be undertaken in order to validate the patent in the designated states. More information on the validation procedure and the language requirements of the contracting states can be found in the brochure ‘National Law relating to the EPC’.
Application not amended
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, and one extra page is added to account for any pages with bibliographic data and the abstract.
If amendments are filed on entry into the European phase, the page fee depends on the language in which the international application was published, i.e. one of the EPO languages or another language such as Japanese:
1. International publication in an official EPO language
If the description has been amended, the page fee is based on the description as published. In this case, the amended pages replace the respective pages of the description as published.
If the claims have been amended, you must submit the entire set even if the amendment concerns only some of them.
2. International publication not in an official EPO language
A description drafted partly in an EPO language and partly in another language such as Japanese cannot be taken as a basis for calculating the page fee. Therefore, if amendments are filed, the page fee is based on the translation of the international application which has to be submitted on entry into the European phase (Article 153(4) EPC, Rule 159(1)(a) EPC).
If the description has been amended, the page fee is based on the entire translation of the description no matter what the extent of the changes. In this case, the amended pages replace the original ones.
If only the claims are amended, the page fee is based on the description as published in Japanese plus the translation of the entire set of claims as amended.
Please be aware that any amendments under Article 19 PCT and/or Article 34 PCT are also considered part of the international publication and must be taken into account for the page fee unless you have indicated that the procedure in the European phase is not to be based on them. The indications you make in section 6 of EPO Form 1200 should be clear, so the EPO can readily identify the pages for which the page fee is payable. It is also advisable to complete the table on the last page of EPO Form 1200 as it will help you to calculate the correct page fee.
International application published in Japanese totalling 100 pages:
description: 80 pages; claims: 15 pages; drawings: 4 pages; abstract: 1 page.
On entry into the European phase, an English translation of the international application is filed.
No amendments are filed.
The page fee is calculated for the 100 pages (minus 35 fee-exempt pages) of the international application as published (i.e. in Japanese).
The claim set has been amended. It replaces the original claims and any claims amended under Article 19 PCT and/or Article 34 PCT. The amended claim set consists of 20 pages.
The page fee is calculated as follows:
Description 80 pages (in Japanese)
Claims 20 pages (in English, as amended)
Drawings 4 pages
Abstract 1 page
105 pages (minus 35 fee-exempt ones)
The claim set and description (pages 5 and 8) have been amended. The new wording replaces the original claims and pages 5 and 8 of the English translation of the original description, as well as any amendments under Article 19 PCT and/or Article 34 PCT. The amended claim set consists of 20 pages. The English translation of the description (including the replacement pages) consists of 100 pages.
The page fee is calculated as follows:
Description 100 pages (pages 1-4, 6-7 and 9-100 of the
English translation, amended pages 5 and 8)
Claims 20 pages (in English, as amended)
Drawings 4 pages
Abstract 1 page
125 pages (minus 35 fee-exempt ones)
For details, see OJ EPO 2009, 338, in the Guidelines for Examination in the EPO, A-III, 13.2 and in the Euro-PCT Guide, 537-544.
From 1 July 2015, applicants may indeed indicate, in response to a communication under Rule 71(3) EPC, that they wish to waive their right to receive a further Rule 71(3) communication as provided for in Rule 71(6) EPC. This option is possible for amendments or corrections to the text proposed by the Examining Division which do not require resumption of the substantive examination proceedings.
Provided that the necessary formal requirements specified in the Notice from the EPO dated 8 June 2015 are fulfilled and the Examining Division has no objections to the amendments or corrections, the Examining Division is deemed to have consented to the waiver. In this case no further communication under Rule 71(3) will be sent to the applicant. Instead, “Information under Rule 71(3) EPC” (Form 2004W) will be published in the European Patent Register, with the aim of informing the applicant and the public of the text in which the Examining Division intends to grant the patent and the related bibliographic data, as approved by the applicant.
The waiver must be expressly indicated. No special form is needed.
With regard to the physical requirements applying for the filing of the amendments, the amendments or corrections must be identified and, where applicable, their basis in the application as filed must be indicated (Rule 137(4) EPC). The relevant pages of the Druckexemplar containing the amendments or corrections must be filed.
In this respect, It is recalled that the submitted replacement pages of the Druckexemplar must be typed, in strict compliance with Rule 50 (1) in conjunction with Rule 49(8) EPC.
By virtue of Rule 50(2) EPC, amendments and the basis for them may be indicated in handwritten form. However, if this is done, a clean copy complying with the requirements of Rule 49(8) EPC must be filed in addition.
In respect of the payment of the fees, it is to be noted that the fee for grant and publication, and any additional claims fees due under Rule 71(4) EPC will not be debited automatically. These fees must be paid separately by another means of payment allowed under the Rules relating to Fees.
Also the designation fee and a renewal fee becoming due under Rule 71a(3) and (4) EPC should also be paid separately by another permitted method of payment in order not to delay the publication of the mention of the grant. The same applies to the payment of extension fees.
Additional details of the Rule 71(3) waiver can be found in the Notice from the European Patent Office dated 8 June 2015 concerning the possibility to waive the right to a further communication under Rule 71(3) EPC (OJ EPO 2015, A52).
Please see also the Guidelines for Examination in the European Patent Office (revised edition – November 2015) C-V, 4.11.
