After a long period of uncertainty with many imponderables, the Agreement on a Unified Patent Court is finally expected to enter into force and the Unified Patent Court to start its work. According to the roadmap (still with previous timetable) published on the website of the Unified Patent Court, the Agreement should enter into force postponed on 1 June 2023. Accordingly, the so-called preparatory sunrise period is to start on 1 March 2023.

In order to equip you in the best possible way for the start of the Unified Patent Court, we at Kather Augenstein have been dedicated to this topic for many years and have actively prepared ourselves to protect and enforce your intellectual property rights also in this new legal system.

For example, our partner Miriam Kiefer LL.M. and our partner Dr Christof Augenstein comment on the Unified Patent Court (UPC), inter alia, in the Beck Online Commentary Fitzner/Lutz/Bodewig on the provisions of the Agreement on the Unified Patent Court. Furthermore, Dr Christof Augenstein is co-editor of the international commentary Augenstein/Wilson/Agé on the procedural law of the Unified Patent Court, for which he and Miriam Kiefer LL.M. are also authors. Finally, Dr Christof Augenstein chairs the Standing Committee Unitary Patent/Unified Patent Court (UP/UPC) Q 243 at AIPPI (Association Internationale pour la Protection de la Propriété Intellectuelle – International Association for the Protection of Intellectual Property) and works for CEIPI (Center for International Intellectual Property Studies at the University of Strasbourg).

These are only excerpts from our comprehensive preparation, with which we as a team are ideally prepared to represent your case before the Unified Patent Court. Part of our preparations is, in particular, the expansion of our team in order to be equipped for the upcoming challenges. With a total of 14 attorneys-at-law specialised in contentious patent law, we form a powerful team also before the Unified Patent Court. To put together the right litigation team for your case, we also draw on a large network of patent attorneys and colleagues from other jurisdictions.

To enable you to deal in depth with all topics relating to contentious proceedings before the Unified Patent Court, we set up a comprehensive series of seminars in which we not only explained the basic features of proceedings before the Unified Patent Court, but also guided the participants through all procedural subtleties. The seminar series covered the entire procedure before the Unified Patent Court from the preparation of an action to the enforcement of a decision. We provide the associated videos on this page for you to refer to at any time.
