In this section, we will examine how EU law applies to our patent procedures and how it functions.
Application of EU Law
If the UPC has jurisdiction
If the UPC has jurisdiction, EU law is directly applicable.
Indeed, the UPC Agreement specifies that the court must apply EU law (Articles 20 and 24 of the UPC Agreement).
If the UPC does not have jurisdiction
If the UPC does not have jurisdiction, EU law is normally not taken into consideration since the EPC is a source of international law and not EU law.
However, the EPO may well recognize certain general principles of law common to all Member States (and as many Member States are also members of the Union…) (D11/91).
Interpretation of EU Law
The question of the interpretation of EU law necessarily arises.
Indeed, several points must be noted before proceeding further:
- The CJEU reserves the exclusive right to carry out this interpretation, as otherwise divergences in interpretation would arise and the uniformity of the application of the law would be compromised (Article 267 TFEU);
- Only national courts may refer questions for a preliminary ruling on interpretation (i.e., an international court does not have this capacity) (Article 267 TFEU).
Thus, to enable the UPC courts to refer questions for a preliminary ruling and thereby correctly apply EU law, the various parties negotiating the UPC Agreement skillfully arranged for a UPC court to be, in reality, a national court (or more precisely, a common court of each Member State, Article 1 of the UPC Agreement).
This was, moreover, a requirement according to the CJEU’s opinion on the predecessor of the UPC (Opinion 1/09 of March 8, 2011, CJEU).
This “common” court nonetheless greatly simplifies matters in practice, particularly for the enforcement of decisions: when a UPC court issues a decision, it is a decision of a French, Belgian, German, etc., court.
Sources of EU Law
EU Treaties
The European Union is governed by numerous historical treaties, but two main treaties may be cited:
Derived Sources
Derived EU law consists of other sources of EU law, defined in Article 288 TFEU:
- Regulations, equivalent to national laws at the EU level: they establish norms directly applicable in each Member State.
- Directives, with a unique legal status: addressed to all Member States or sometimes to certain ones, they set mandatory objectives but generally leave Member States free to choose the means to achieve them within a specified timeframe.
- Decisions, binding on a limited number of addressees.
- Recommendations and opinions, which are not binding on the Member States to which they are addressed. However, the Court of Justice of the European Union considers that a recommendation may be used to interpret national or EU law.
This derived law is, by far, the most abundant source of law.
Fundamental rights and general principles of Union law
There is no exhaustive list of fundamental rights and general principles of Union law, but the following can be cited:
- Fundamental rights
- the right to property;
- freedom to conduct a business;
- inviolability of the home;
- freedom of opinion;
- protection of the family;
- protection of private life;
- freedom of religion and belief;
- equal treatment;
- General principles
- primacy of Union law;
- principle of subsidiarity;
- respect for fundamental rights;
- principle of proportionality.
Among fundamental rights, it should be noted that there are a number of absolute rights (i.e., rights that do not admit of any exception), such as the prohibition of torture.
Of course, for a principle to be recognized as a general principle of Union law, a number of indicators are required, and the mere mention of a concept in the treaties is not sufficient to render it general (e.g., C-147/13, in which Spain argued that the use of all Union languages was a general principle and therefore opposed the limitation of languages before the EPO to three official languages).
Charter of Fundamental Rights
First proclaimed in Nice on 7 December 2000 and officially adopted in its final version by the Presidents of the European Commission, the European Parliament, and the Council of the European Union on 12 December 2007, the Charter of Fundamental Rights acquired binding legal force with the Treaty of Lisbon.
Article 6 TEU provides, in its first paragraph, that this Charter has « the same legal value as the Treaties. »
Regarding intellectual property rights, this Charter states, in its Article 17, that intellectual property rights must be protected.
External agreements concluded by the EU
External agreements are conventions concluded between, on the one hand, the European Union with or without its Member States, and on the other hand, third countries, regional groupings, or international organizations.
For example, agreements concluded within the framework of the World Trade Organization (WIPO) are external agreements.
Case law of the CJEU
Case law includes the judgments of the two courts of the Court of Justice of the European Union:
- the Court of Justice and
- the General Court.
This case law is particularly important as it ensures a uniform interpretation of the treaties.
Of course, this case law occasionally defines the general principles of Union law (as discussed above) as well as fundamental rights.
Hierarchy of sources of law
To summarize the hierarchy of sources of Union law mentioned above, the following diagram can be used:

Balance between the different sources of law
Introduction
If two sources of law, of different hierarchical levels, conflict, the source with the higher hierarchy prevails.
This is straightforward, but difficulties may arise when these two sources are of the same « level, » for example:
- if the principle of equal treatment conflicts with the principle of property;
- if the principle of free movement conflicts with the principle of public health.
Balance in the Field of IP
The field of IP gives rise to a number of situations in which IP rights interfere with principles of the Union:
- right to property;
- right to privacy (e.g., filtering systems, C-160/15, 8 September 2016, CJEU);
- freedom to conduct a business (C-160/15, 8 September 2016, CJEU);
- freedom of expression (e.g., reuse of a work for political or commercial purposes, C-201/13, 3 September 2014, CJEU);
- etc.
Each situation must therefore be resolved with the principle of proportionality in mind.
Principle of Proportionality
This principle of proportionality is a general principle of the Union (Case 11/70, 17 December 1970, ECJ, now codified by Art 5.4 TEU and Art 52.1 of the Charter of Fundamental Rights).
Normally, this principle of proportionality should be applied by verifying a three-step test:
- verifying that the law is suitable (i.e., it achieves the intended objective);
- verifying that the law is necessary (i.e., there is no other means of achieving the intended objective, given its impact);
- verifying that the law is balanced with the principle it calls into question.
However, the CJEU may be more flexible and apply only the first two tests (C-58/08 of 8 June 2010, ECJ) or only the last test (C-70/10 of 24 November 2011, ECJ).
The CJEU may even only require that the Union measure in question is not manifestly disproportionate (C-331/88, ECJ).
In short, this principle of proportionality is quite flexible 🙂
