One of the two organs of the European Patent Organisation

The European Patent Office (EPO) is one of the two organs of the European Patent Organisation (EPOrg), the other being the Administrative Council. The EPO acts as executive body for the organisation while the Administrative Council acts as its supervisory body The actual legislative power to revise the European Patent Convention lies with the Contracting States themselves when meeting at a Conference of the Contracting States. Within the European Patent Office, examiners are notably in charge of studying European patent applications, filed by applicants, to decide whether to grant a patent for an invention. The patents granted by the European Patent Office are called European patents.

The European Patent Office (EPO) grants European patents covering the Contracting States to the European Patent Convention and several other states that have concluded extension and validation agreements with the EPO. The EPO provides a single patent grant procedure, but not a single patent from the point of view of enforcement. Hence a patent granted by the EPO is not a single or unitary European Union patent or uniformly recognised Europe wide patent, but a bundle of national patents.

Since the European patent with unitary effect (also called "unitary patent") entered into force on 1 June 2023, some administrative tasks relating thereto are performed by the EPO. Those tasks include the collection of renewal fees and registration of unitary effect upon grant, exclusive licenses and statements that licenses are available to any person. Decisions of the EPO regarding the unitary patent are open to appeal to the Unified Patent Court (UPC), rather than to the EPO Boards of Appeal.

The European Patent Office is not a legal entity as such, but an organ of the European Patent Organisation, which has a legal personality.

The three official languages of the European Patent Office are English, French and German and publications including the European Patent Bulletin and Official Journal of the European Patent Office are published in all three of those languages. European patent applications may be filed in any language provided that a translation into one of the official languages is submitted within two months if the language of filing is not an EPO official language. The official language in which the application is filed or into which it is translated is taken to be the language of the proceedings and the application is published in that language. Documentary evidence may also be submitted in any language, although the EPO may require a translation. Some Contracting States to the European Patent Convention have an official language which is not an official language of the EPO, such as Dutch, Italian or Spanish. These languages are referred to as "admissible non EPO languages". and there is a period of one month for filing a translation into an official language or the document is deemed not to have been filed.

In the international procedure according to the Patent Cooperation Treaty (PCT), the European Patent Office acts as a Receiving Office, an International Searching Authority (ISA), an International Preliminary Examining Authority (IPEA) and, with effect from 1 July 2010, as a so called Supplementary International Searching Authority (SISA). The Patent Cooperation Treaty (PCT) provides an international procedure for handling patent applications, called international applications, during the first 30 months after their first filing in any country party to the PCT. The European Patent Office does not grant "international patents," as such patents do not exist. After 30 months (or, for a few countries, after 20 months) an international application must be converted into national or regional patent applications, and then are subject to national/regional grant procedures. As Supplementary International Searching Authority (SISA), the European Patent Office has announced that it will conduct no more than 700 supplementary international searches per year.

The EPO offers on its web site several free services, including Espacenet and Open Patent Services (OPS) for searching within its collection of patent documents, the legal texts published in its Official Journal, the European Patent Register containing legal information relating to published European patent applications and European patents (the European Patent Register also allowing the inspection of files under ), and a publication server of the European patent applications and patents. There is also the CMS software for filing European patent applications online.

The main staff union active within the EPO is the "Staff Union of the European Patent Office" (SUEPO). As an international organization, EPO enjoys immunity and national courts have—in principle—no jurisdiction regarding disputes in which EPO is a party. Labour disputes can be submitted by employees to the Administrative Tribunal of the International Labour Organization (ILOAT). Courts in the Netherlands have however on occasion taken jurisdiction when it found a breach of fundamental principles of human rights, based on European Court of Human Rights case law. Jurisdiction was assumed for example because the ILOAT procedure (of over 3 years) was too lengthy for a process involving health issues or regarding a conflict with labour unions, as no appeal to ILOAT or any other judicial organization was possible. The background to the latter judgment was the ongoing conflict between EPO staff and management, in particular the refusal of EPO to recognise the staff unions, blocking of e mail communication between the unions and their members and restriction of the right to strike. Opstelten's intervention was criticised by a number of Dutch legal experts including Cedric Ryngaert, Professor of International Law in Utrecht, who considered the Minister's intervention to be unusual: "Basically he erodes the power of the Court. International organisations are going to increasingly put themselves above the law, which is already a problem now. Opstelten relies on an Act from the seventies, which must be applied dynamically. Instead he takes a very conservative view." Staff discontent has been attributed to Battistelli's style of management which, according to reports in the German newspapers Die Zeit and Die Welt, was perceived by staff as being unduly autocratic and unsuited to a European intergovernmental body such as the EPO. Concern has been expressed regarding the high number of suicides of EPO employees, five in over three years. The EPO President Battistelli dismissed the suggestions by EPO staff union SUEPO of a possible link between the suicide and working conditions at the EPO as "totally inappropriate" and accused the staff union of "abusing a personal tragedy and inciting controversy". The EPO staff union SUEPO said that a direct link between the suicide and the working conditions had not been demonstrated but that the Dutch Labour Inspectorate should be given the opportunity of investigating the matter.

In June 2018, the German Federal Court of Auditors (link=no) and financial experts criticized the planned establishment by the EPO of a fund, called "EPO Treasury Investment Fund" (EPOTIF), to manage 2.3 billion euros of its assets, the fund including risky financial products such as asset backed securities, mortgage backed securities, and credit default swaps.

At the end of the 2010s and into the 2020s, a decline in the quality of patents granted by the EPO was reported and criticised, as the decline in the quality of searches and examinations at the EPO is seen as harmful to the industry (more invalid European patents granted means more legal uncertainty in the market).
