Unified Patent Court (UPC)
Most patent cases in Europe are nowadays brought before the Unified Patent Court (UPC). The UPC is a single venue for proceedings to enforce or invalidate Unitary patents (UPs) and European patents (EPs) (and any supplemental protection certificate based on it). The UPC’s decisions have effect for the whole of the UPC (and sometimes for other EP countries – in so-called cross-border decisions). Eighteen countries currently take part in the system (including Germany, France, Belgium and the Netherlands), and further EU member states may join in the future.
As one of Europe’s leading IP firms, we understand the challenges and opportunities the UPC system brings for parties to pan-European patent litigation. We helped conceive the new procedural system and are familiar with the cultural and legal differences that affect the UPC. Our more than 70 UPC representatives have many years of cross-border patent litigation experience in all key European jurisdictions.
The 18 participating countries are Austria, Belgium, Bulgaria, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxemburg, Malta, the Netherlands, Portugal, Romania, Slovenia and Sweden.
What sets us apart
1. Leading UPC firm
HOYNG ROKH MONEGIER has been at the forefront of UPC litigation from the outset. As one of the very few international IP boutique firms in Europe, we provide consistent top-tier quality in patent litigation. Our partners have done so for the past decades in national and international litigation, and we continue to do so before the UPC. With over 70 UPC representatives and integrated international teams of lawyers and patent attorneys working seamlessly across jurisdictions, we offer the scale and depth required for the most complex patent disputes. We are consistently ranked among the top-tier firms for UPC and patent litigation, and are acting in many of the Court’s most prominent and high-profile cases. This gives clients the benefit of a team that combines first-rate legal advocacy, technical understanding and coordinated pan-European execution.
2. Inside knowledge
We helped build the new system. Several of our partners were actively involved in conceiving the UPC system and the training of patent judges, and continue in advisory roles. Willem Hoyng, for example, joined the committee that developed the rules of procedure for the new courts and the committee advising the preparatory committee. This close involvement and inside knowledge of the new procedural system gives us a tactical advantage over most other European patent firms.
This was proven in practice: since the opening of the new court, our patent litigators have been entrusted with a very substantial number of UPC cases, quickly and firmly positioning us among the leaders in UPC litigation.
3. In depth knowledge of local custom
Traditionally, Germany, the Netherlands, France and Belgium have been the most important patent litigation venues in continental Europe. All of these countries host their own UPC divisions and, as expected, some “local custom” remains notwithstanding the UPC’s uniformity. Proper understanding of such custom constitutes a competitive edge, if only because the most experienced UPC judges come from these jurisdictions. Our seasoned patent litigators know the case law and background of these judges and devise the best litigation strategy for each case.
4. The necessary resources and expertise
Our team consists of more than 70 UPC representatives. Together they cover the entire spectrum of patent disputes. Regardless of the field – pharmaceuticals, biotechnology, chemicals, mechanics, high-tech or telecommunication systems – our people understand the technology and have over forty years of experience in pan-European patent litigation. They can recommend the best strategies to pursue in a given case. Our firm includes technically trained patent attorneys who support our trial lawyers where necessary, resulting in cost-efficient litigation teams.
5. Highly skilled continental trial lawyers
Our patent litigators are genuine trial lawyers. They know the best litigation strategies and have the requisite skillset to win in the courtroom. They have extensive experience litigating in all leading patent jurisdictions in continental Europe. The UPC system is primarily based on the continental system, which our lawyers know like the back of their hand. Our expertise wins cases.
