ExploreAbout this exam
The European qualifying examination (EQE) is the professional examination that tests whether a candidate has the knowledge and aptitude needed to represent applicants in proceedings before the European Patent Office. It was established in 1979 and, according to the EPO, has been passed by more than 14 000 candidates; it is widely regarded as one of the most demanding professional examinations. It is aimed at people who are completing the mandatory period of professional activity under the supervision of a professional representative, or who deal with patent matters as an employee of an industrial company established in a contracting state, and who already hold a scientific or technical qualification.
The examination is currently being rebuilt. The EQE usually takes place once a year and comprises five papers. Paper F, first held in 2025, tests declarative knowledge in procedural patent law and claim analysis. Papers M1 and M2 were first held in 2026; M1 concerns analysing and assessing information and acting on client instructions, M2 the procedural and substantive patent law of the EPC and the PCT. Papers M3 (drafting claims, responding to Office actions, opposition) and M4 (advising the client with a legal opinion) follow in 2027. The examination is online, open book, and covers only legal texts in force on 31 October of the year preceding the examination.
Preparation therefore means working through the REE 2025 and IPREE 2025, the EPC, PCT and Paris Convention, and Board of Appeal case law, and practising on the mock examinations and compendium material the EPO publishes.
What you'll study
About EQE preparation
What does the exam look like on the day?
The EQE is held online and can be taken at any suitable location the candidate chooses. The examination software is Wiseflow; proctoring uses image and audio recording, with monitoring by artificial intelligence complemented by human invigilation. Candidates may use any books and documents they consider useful when answering the papers, so the exam is effectively open book.
How hard is the EQE, and what makes it hard?
The EPO describes it as widely regarded as one of the most demanding professional examinations, and it has been passed by more than 14 000 candidates since 1979. The difficulty comes less from memorising law than from applying it accurately under time pressure to realistic client scenarios, which is why the mandatory training period is treated as essential preparation.
Can I retake a paper if I fail?
The source page does not set out a retake policy, so no number of attempts or waiting period should be assumed. What it does describe is a detailed system of exemption between former and modular papers laid down in the REE 2025, and transitional measures for candidates who sat a paper under the REE 2009. Check the REE 2025 and the Examination Secretariat notices for your position.
When do I have to register and enrol?
Registration as a candidate is compulsory and must be done at the latest by 31 May of the year in which you intend to enrol for the examination for the first time; candidates who have not registered in time cannot enrol. For the EQE 2027, enrolment for paper F opened on 8 April 2026 and for papers M1 to M4 on 7 July 2026, with applications closing on 30 September 2026 via the EQC portal.
Which law is examinable?
The content of the examination only relates to legal texts which were in force on 31 October of the year preceding the examination. So for a given year's EQE, amendments entering into force after that cut-off are not examinable. Candidates need to be particularly conversant with European patent law, the PCT, the Paris Convention, EPO board of appeal case law and certain national laws.
How long must I have trained before sitting a paper?
The required period of professional activity depends on the paper: one year for paper F, two years for papers M1 and M2, and three years for papers M3 and M4. The training period must be completed at the date of the examination, and only periods completed after you obtained the required qualifications are taken into account.
In what order should I take the papers?
The progressive roll-out gives a natural sequence: paper F first in 2025, then M1 and M2 in 2026, then M3 and M4 in 2027. The training requirements reinforce this, since F needs one year, M1 and M2 two years, and M3 and M4 three years. Note that the main exam papers A, B, C and D were held for the last time in 2026.
What are the most common ways candidates lose marks?
The source does not publish failure statistics or an official list of common errors, so treat any such list with caution. What it does stress is that a great deal of the required knowledge is gained during the mandatory practical training, and that candidates must take part in a wide range of activities pertaining to patent applications or patents - so thin, narrow training is the clearest known risk.
How should I prepare, and where are practice materials?
Mock examinations can be found in the Compendium area of the EPO's EQE pages, and the site also points to a guide for preparation. Shortly before the EQE, practical tests are offered for enrolled candidates to prepare for the online examination. Working through those, plus the REE 2025, IPREE 2025 and the legal texts, is the route the EPO itself signposts.
Is this page affiliated with the EPO or the EQE?
No. This is independent study material written for candidates searching for the exam; it is not produced, endorsed or approved by the European Patent Office, the Examination Board or the Examination Secretariat. Always verify procedural details, deadlines and fees against the official EPO EQE pages, the REE and IPREE, and the Examination Secretariat notices before acting.
