EPO (European Patent Office)

Definition : EPO (European Patent Office)

The European Patent Office is an organization that grants patents at European level. Its headquarters are in Munich, Germany. It also has a department in the municipality of Rijswijk in the Netherlands, an annex in Berlin and offices in Vienna and Brussels.

Naissance de l’OEB

Created by the European Patent Convention (EPC), signed in Munich in 1973, the European Patent Office (EPO) began operating in 1977. The main aim of the organisation was to simplify the grant of a European patent valid in several countries at once, without going through a national procedure in each State. The system gave inventors a more efficient route to securing protection for their inventions throughout the territory of the EPC contracting States.

Aujourd’hui, l’OEB regroupe 39 États membres, including the countries of the European Union but also other European countries such as Switzerland, Norway and Türkiye. The Office is independent of the European Union, although it plays a central role in European intellectual property.

La structure et l’organisation de l’OEB

The EPO is an intergovernmental office headquartered in Munich, Germany. It also has offices in The Hague (Netherlands), Berlin, Vienna and Brussels.

The EPO is organised around several key bodies:

  1. The President of the EPO, who heads the Office and is responsible for its administrative management.
  2. The Administrative Council, made up of representatives of the contracting States, which supervises the Office’s activities and adopts certain rules governing filing and examination procedure.
  3. The Boards of Appeal, which hear appeals against decisions of the Office, in particular refusals to grant or revocations of a European patent.

The EPO employs more than 6,000 staff from a range of European countries, which ensures a multinational and neutral approach to the handling of patent applications.

The powers of the EPO

The EPO is responsible for examining and granting European patents. It does not grant a single European patent, but a bundle of national patents valid in the countries designated by the applicant.

The EPO’s principal powers are:

  1. Receipt of applications : the Office receives European patent applications. They may be filed directly with the EPO, or through the national office of a contracting State.
  2. Examination of patentability : the EPO determines whether the invention meets the conditions for protection laid down by the EPC — novelty, inventive step and industrial application.
  3. Publication : applications are generally published 18 months after filing. Publication allows any third party to access the content of the invention and, where appropriate, to oppose it.
  4. Délivrance : if the application meets all the conditions, the EPO grants the patent. The patent must then be validated in each designated country, which may involve translating the text and paying national fees.
  5. Procédures d’opposition et de recours : after grant, any third party may oppose the validity of the patent before the EPO. Decisions may be appealed to the Office’s Boards of Appeal.

La procédure devant l’OEB

La procédure de dépôt auprès de l’OEB suit plusieurs étapes. Tout d’abord, le déposant doit provide a complete description of the invention, together with claims defining the subject-matter protected. A filing fee is payable at this stage.

Once the application has been published, substantive examination begins. At this stage the EPO assesses whether the patentability criteria are met. If the outcome is favourable, the Office notifies the grant of the patent.

Once granted, the European patent becomes a bundle of national patents. Renewal fees must be paid regularly in each country to keep them in force. It is also possible, under certain conditions, to limit or revoke a patent even after grant.

An essential tool for intellectual property in Europe

Thanks to the EPO, companies, researchers and inventors have a powerful tool for securing protection of their inventions across wide territories. By offering a centralised procedure, the European Office simplifies the formalities and reduces costs compared with national filings in each country.

L’OEB joue également un rôle important en matière d’information technologique. Sa base de données, Espacenet, gives free access to millions of European and worldwide patents, whether published or granted, which supports technology watch and innovation.

It should be noted that, since the entry into force of the European patent with unitary effect (which is not administered directly by the EPO, but is closely linked to it), a further step has been taken towards more coherent and centralised European intellectual property protection.

In short, the European Patent Office is a key actor in European intellectual property. Through its mission, its rigorous procedure and its role as technical arbiter, it maintains a balance between protecting inventors and giving society access to innovation. For anyone seeking to protect an invention in Europe, understanding the role of the EPO is indispensable.
