Commentary
The Patent Mediation and Arbitration Center (PMAC) is established by Art. 35.1 UPCA. It is located in Ljubljana, Slovenia, and Lisbon, Portugal. It is an integral part of the UPCA and is expected to start its work in 2026.
PMAC is a service for mediation and arbitration in all patent related disputes under the UPC, except decisions to revoke or limit a patent in mediation or arbitration proceedings (Art. 35.2 UPCA).
Related Rules
A) EU directive 2008/52/EC
In mediation procedures, this directive on certain aspects in mediation on civil and commercial matters established to facilitate the amicable resolution of disputes provides basic rules. This directive applies according to Art. 2.1 to cross-border disputes in which at least one of the parties is domiciled or habitually resident in a Member State other than that of any other party. A cross-border dispute shall also be one in which judicial proceedings or arbitration following mediation between the parties are initiated in a Member State other than that in which the parties were domiciled or habitually resident (Art. 2.2). According to Art. 8 of EU directive 2008/52/EC, the parties shall not subsequently be prevented from initiating judicial proceedings.
The parties must have the right to seek a judicial judgement by a court. This is a general principle to be considered in contractual mediation and arbitration clauses and in agreements between the parties in the attempt to amicably settle the UPC dispute by aid of mediation or arbitration.
In CJEU Judgement of 14/06/2017 - C-75/16, ECLI:EU:C:2017:457, paras. 51, 54 + 56 it is stated “what is important is not whether the mediation system is mandatory or optional, but the fact that the parties’ right of access to the judicial system is maintained”. [...] “Nevertheless, it is settled case-law of the Court that fundamental rights do not constitute unfettered prerogatives and may be restricted, provided that the restrictions in fact correspond to objectives of general interest pursued by the measure in question and that they do not involve, with regard to the objectives pursued, a disproportionate and intolerable interference which infringes upon the very substance of the rights guaranteed (CJEU Judgment of 18 March 2010, Alassini and Others, C‑317/08 to C‑320/08, EU:C:2010:146, para. 63 and the case-law cited).” [...] “Member States are free to choose the means they deem appropriate for the purposes of ensuring that access to the judicial system is not hindered. The fact, first, that the outcome of the ADR procedure is not binding on the parties and, secondly, the fact that the limitation periods do not expire during such a procedure are two means which, amongst others, would be appropriate for the purposes of achieving that objective.“
B) Rules of Operation of the PMAC (PMAC RoO)
The Administrative Commitee of the UPC established the Rules of Operation of the PMAC on 08/07/2022. This provides the organizational structure of the PMAC and general rules for the venue of mediation and arbitration (R. 4 PMAC RoO) and for the list of arbitrators and mediators (R. 14 PMAC RoO).
C) PMAC Rules of Procedure
PMAC shall establish Mediation and Arbitration Rules according to Art. 35 (3) UPCA and criteria and qualifications for arbitrators and mediators to be admitted to the list which have to be accepted by the administrative committee (R. 14.2 PMAC RoO). Draft PMAC rules have been published on 13/05/2025 for commentary.
Mediation Procedure
Mediation is an attempt to settle a dispute with guidance (mediation) of a mediator (see also R. 11.1 RoP). According to R. 11.1 RoP, the deadlines are suspended when mediation is initiated.
PMAC is, according to Art. 2 (5) PMAC Mediation Rules (PMAC RoM), the only body authorized to administer the mediation proceedings under the Mediation Rules of PMAC. PMAC is established under Art. 35 UPCA for mediation and arbitration of patent disputes falling within the scope of the UPCA. However, this does not exclude mediation or arbitration by other bodies, e.g. WIPO Arbitration and Mediation Center.
Language of Mediation
The language of the Mediation is agreed by the parties, or, in the absence of an agreement, shall be the language which PMAC considers is most closely related to the dispute (Art. 14 PMAC RoM).
The language of the mediation procedure can be different to the working languages of the Centre, which shall be English, French and German (Art. 6.1 PMAC RoO).
Length of Mediation procedure
Art. 15.4 PMAC RoM intends efficient Mediation within three months starting from the appointment of the Mediator. However, this period may be extended by the Centre with the agreement of the Mediator and all the parties. Disagreement of a party allows the party to step out of unsuccessful mediation and proceed with the UPC procedure. The maximum duration is limited in that PMAC may terminate the Proceedings on the expiry of a period of 12 months from the date of appointment of the Mediator, following consultation with the Mediator and the parties. This is a ground for termination according to Art. 17 .1 lit. b) PMAC RoM. The Mediator and the parties shall make all effort to reach an expeditious and efficient resolution of the dispute. They can agree on a meeting agenda and a time schedule.
Initiation or Continuation of parallel Proceedings in Mediation
Art. 21.3 PMAC RoM expects from the parties to expressly undertake not to initiate or actively continue any judicial, arbitral or similar proceedings to a dispute which is subject to the pending Proceedings at PMAC. This allows the parties to negotiate a settlement without pressure by injunction claims or invalidations or restrictions of the patent in dispute. However, suspension of parallel procedure is not mandatory. According to Art. 21.4 PMAC RoM, initiation or continuation of such parallel proceedings does not in itself constitute a waiver of the Mediation Agreement or a declaration of termination of the Mediation Proceedings.
In FRAND procedures, Art. 25 PMAC RoM allows continued parallel proceedings. In case only parts of a dispute are referred to Mediation, the parties may agree that any undertaking made under Article 20 PMAC RoM does not apply, and Proceedings concerning other parts of the dispute that are not subject to the pending Mediation at the Centre can continue. This may cause the defendant to accept a mediation agreement under pressure. The threat of an injunction may cause the implementer to raise royalties for a SEP portfolio including alleged SEPs that are, in reality, invalid, not essential, or not infringed. [R. Nazzini: Global licences under threat of injunctions: FRAND commitments, competition law, and jurisdictional battles, in: Journal of Antitrust Enforcement, 2023, 11, 427–453, 443 - https://doi.org/10.1093/jaenfo/jnad002]
Mediation in FRAND Disputes
Section 5 of PMAC RoM is directed to FRAND disputes, which are related to Standard Essential Patents (SEP), in particular an international SEP portfolio comprising more patents than the unitary patent in a UPC dispute, and which are linked to patent and antitrust law. A core dispute is the question of Fair Reasonable and Non-Discriminatory licence offer of the SEP owner and willingness of defendant to take a FRAND licence.
Thus, mediation is not limited to the unitary patent in dispute and directly related disputes. According to Art. 22 (2) PMAC RoM, the matters raised in mediation may include:
a) the SEP(s) in dispute or other patents concerned, such as one or several or a sample of patent(s) from the patent portfolio(s), in which case the parties may agree on the sampling criteria;
b) any patents that might be subject to cross-licensing;
c) the claims and defenses;
d) the conduct of the Proceedings in multiple stages;
e) any essentiality assessment to be conducted in accordance with the Centre’s rules on expert determination;
f) the determination of selected licensing terms and conditions;
g) the determination on a temporary basis of any selected licensing terms pending determination of final licensing terms by a competent tribunal;
h) the determination of the scope of the royalty base and range;
i) the methodology for calculating a FRAND royalty rate;
j) any application for an order to a competent court, such as an application for an order to produce evidence or an order concerning confidentiality.
Arbitration Procedure
Arbitration is a procedure resulting in a decision of the board of arbitrators.
In CJEU, Judgement of 20/06/2022 - C-700/20, ECLI:EU:C:2022:488, para. 58, it is stated that “an arbitral award can, by means of a judgment entered in the terms of that award, produce effects in the context of Article 34.3 of Regulation No 44/2001 only if this does not infringe the right to an effective remedy guaranteed in Article 47 of the Charter of Fundamental Rights of the European Union (see, to that effect, CJEU judgment of 25 May 2016, Meroni, C‑559/14, EU:C:2016:349, para. 44) and enables the objectives of the free movement of judgments in civil matters and of mutual trust in the administration of justice in the European Union to be achieved under conditions at least as favourable as those resulting from the application of Regulation No 44/2001 (see, by analogy, CJEU judgments of 4 May 2010, TNT Express Nederland, C‑533/08, EU:C:2010:243, para. 55, and of 19 December 2013, Nipponka Insurance, C‑452/12, EU:C:2013:858, para. 38).” The advocate general stated in his opinion of 16. January 2025 in CJEU case C-600/23, ECLI:EU:C:2025:24, para. 136 that “Article 19.1 TEU, read in conjunction with Article 267 TFEU and Article 47 of the Charter, does not preclude a rule of national law granting an arbitral award rebuttable probative value vis-à-vis third parties, where the review of conformity with EU law has been carried out by a court of a third country”.
In the UPC procedure, the arbitration decision provided in the interim procedure to explore the possibility of a settlement (Art. 52.2 UPCA) is not finally binding. The parties can proceed with the court procedure in case a party does not agree with the outcome. Therefore, a review of conformity with EU law by EU courts is guaranteed.
Judicial enforcement of a mediation settlement and an arbitral award
The terms of any settlement or arbitral award by consent, reached using the facilities of PMAC, shall be confirmed by the UPC by decision (R. 11.2 RoP). This includes a term which obliges the patent owner to limit, surrender or agree to the revocation of a patent or not to assert it against the other party and/or third parties. A request for decision by the parties is required (R. 365.2 RoP). Art. 2.2 PMAC Mediation Rules reflects the rules set out in R. 11.2 and R. 365 RoP.
The UPC decision confirming the settlement can be enforced according to Art. 82 UPCA in any Contracting Member State. An order for the enforcement of a decision shall be appended to the decision by the Court.
The EU Regulation on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters (Brussel 1 bis EU Regulation No 1215/2012 of 12 December 2012) does not apply to arbitration according to Art. 1.2 d) Brussels 1 bis EU Regulation. However, the UPC decision confirming the settlement is a judgment given by a court or tribunal of a Member State in the meaning of Art. 2 a) of the Brussels 1 bis EU Regulation. The decision shall be enforceable in any Contracting Member State according to Art. 82.1 UPCA and can be enforced without any declaration of enforceability being required (Art. 39 Brussels 1 bis EU Regulation).
