European patent law

European patent law covers a wide range of legislations including national patent laws, the Strasbourg Convention of 1963, the European Patent Convention of 1973, and a number of European Union directives and regulations in countries which are party to the European Patent Convention. For certain states in Eastern Europe, the Eurasian Patent Convention applies.

Patents having effect in most European states may be obtained either nationally, via national patent offices, or via a centralised European Union or a Council of Europe institution.[1] A patent granted by the EPO does not lead to a single European patent enforceable before one single court, but rather to a bundle of essentially independent national European patents enforceable before national courts according to different national legislations and procedures.[2] Similarly, Eurasian patents are granted by the Eurasian Patent Office and become after grant independent national Eurasian patents enforceable before national courts.

European patent law is also shaped by international agreements such as the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs Agreement), the Patent Law Treaty (PLT) and the London Agreement.

A characteristic of European patent law as it stands today is that European patents granted by the European Patent Office (EPO), and patents granted by national patent offices are available,[3] and may possibly –if permitted by national law and, if so, to the extent permitted by national law[4]– co-exist within a given jurisdiction. Utility models, referred to as "Gebrauchsmuster" in Germany and Austria, are available in some countries.

Patent applications can be filed at the relevant national patent office or at the European Patent Office. Alternatively, an international application may be filed under the Patent Cooperation Treaty (PCT) and later nationalised in the desired countries or at the EPO. However, Belgium, Cyprus, France, Greece, Ireland, Italy, Latvia, Malta, Monaco, the Netherlands, and Slovenia have "closed their national route" meaning that it is no longer possible to nationalise an international application in those countries directly and protection can only be obtained via the EPO.[5][6]

European patents

A European patent is the product of a unified grant procedure before the European Patent Office (EPO) under procedures established by the European Patent Convention (EPC). A European patent is a regional, non-unitary patent. Some of the 38 EPC Contracting States require the patentee to file a full translation of the granted European patent with the national patent office of the State if the text of the European patent as granted is not in one of their official languages. If the required translation is not filed, the European patent is deemed to have no effect from the outset in that State.[7] The London Agreement, which entered into force on May 1, 2008, significantly reduces the number of required translations in the 20 states that are party to it.

The European patent can be revoked under the laws of a Contracting State on certain grounds (specified in EPC Articles 138 and 139) with effect only in that State. A central time-limited opposition procedure and central limitation and revocation procedures before the EPO are available however. The opposition procedure allows a third party, i.e. any person except the patent proprietor, to oppose a granted European patent in an attempt to have the EPO reconsider the grant of the patent and possibly revoke or amend the patent. The opposition procedure may only be initiated within nine months of the grant of the European patent.[8] The limitation and revocation procedures allow the patent proprietor to centrally request the limitation or revocation of his own European patent.

Unitary patents

Countries may create unitary protection with regards to patents, which means that the effect (including revocation) is equal in all countries concerned. Such unitary protection was effected (both for "national" and European patents) by Switzerland and Liechtenstein in 1980 with the Treaty between the Swiss Confederation and the Principality of Liechtenstein on Patent Protection of 1978.[9]

National patents

National patents are available in all European countries. In some European countries, national patents are substantively examined, while in other countries there is no provision for such examination and patents are thus granted only if formal requirements are met, while novelty and inventive step is not evaluated. It can be cheaper and tactically advantageous to apply for a few national patents rather than for a European patent at the European Patent Office.[10]

In the United Kingdom, for example, the Patents Act 1977 and the Patents Act 2004 establish the law relating to patents including filing, examination, grant, infringement, revocation, assignment. UK law is in many ways similar to the European Patent Convention (EPC) (although the EPC deals with very few post-grant activities).

National patents may be the only available patents in European states that are neither party to the European Patent Convention nor the Eurasian Patent Convention. This is the case for Andorra, Moldova and Ukraine. Montenegro and Bosnia and Herzegovina are extension states to the European Patent Convention, which means that European patents granted are deemed to take effect also in these states, if extension is correctly requested; and provided certain translation and publication requirements are met.

Utility models

In Europe, utility models are available in Austria (Gebrauchsmuster), France ("certificat d'utilité"), Germany ("Gebrauchsmuster"), Italy ("modello di utilità"), Finland ("hyödyllisyysmalli"), Denmark ("brugsmodel"), Russia ("Полезная модель") and Spain[11] (this list is however non-exhaustive). The term of a utility model is usually shorter than the term of a patent and has less stringent patentability requirements.

Differences and similarities between national laws

Substantive patent law has been harmonized to a certain extent across national laws in Europe, notably upon signature of the Strasbourg Convention of 1963 and the European Patent Convention (EPC) of 1973, and upon entry into force of the TRIPs Agreement. In practice however, the interpretation of common substantive provisions have led to different interpretations in different European countries.

Regarding procedural law, and especially regarding the procedures to examine infringement and validity of patents before national courts, significant differences exist across national laws. For instance, while in Germany validity and infringement of patents are examined by different courts in different procedures (in a so-called "bifurcation system"), in the United Kingdom the same court is in charge of examining validity and infringement actions. According to Mr Justice Kitchin, a British judge,

"... it is desirable to try infringement and validity issues together, where at all possible. If they are tried separately it is all too easy for the patentee to argue for a narrow interpretation of his claim when defending it but an expansive interpretation when asserting infringement."[12]

In other words, the German bifurcation system is often regarded as favouring the patentee.[13] In this respect, Lord Justice Jacob referred to a comparison reportedly made by Professor Mario Franzosi between a patentee and an Angora cat:

"When validity is challenged, the patentee says his patent is very small: the cat with its fur smoothed down, cuddly and sleepy. But when the patentee goes on the attack, the fur bristles, the cat is twice the size with teeth bared and eyes ablaze."[14]

The German patent system is, however, "particularly appealing for a large number of users", notably because it is regarded as relatively quick and affordable. The bifurcation character of the Germany system "is considered as both a shortcoming in some respects, and as an advantage in others."[15]

Unitary patents in the European Union

The creation of a European community patent system, which would lead to a single unitary patent in the European Union (or its predecessor the European Community), has been debated since the 1970s. In 2012 agreement was reached between all European Union Member States except Italy and Spain on a European patent with unitary effect, more commonly known as the unitary patent, a proposed new type of patent that would be valid in participating member states of the European Union.[notes 1] Unitary effect can be registered for a European patent upon grant, replacing validation of the European patent in the individual countries concerned. The unitary effect means a single renewal fee, a single (group of) owner(s), a single object of property, and uniform protection, which means that revocation as well as infringement proceedings are to be decided for the unitary patent as a whole rather than for each country individually. Licensing is however to remain possible for individual countries.

Agreement on the two EU regulations[16][17] which make the unitary patent possible was reached during the European Council of 28–29 June 2012, and by the European Parliament on 11 December 2012.[18] The provisions will apply once the related Agreement on a Unified Patent Court, which was signed by all EU member states except Croatia, Poland and Spain, enters into force. However, Spain has introduced two actions for annulment,[19] against the two regulations, which are pending before the EU Court of Justice.

Other legal agreements have been proposed outside the European Union legal framework to reduce the cost of translation (of patents when granted) and litigation, namely the London Agreement (which entered into force in 2008) and the European Patent Litigation Agreement (EPLA) (which never entered into force).


Based on data from Germany, France, the Netherlands, and the UK, the Centre for European Economic Research (ZEW) found that German courts handle by far the largest number of patent litigation cases.[20]
