What seemed uncertain for a long time happened yesterday: The United Kingdom has ratified the planned European Patent Court (UPC). The United Kingdom is thus taking an important step towards being able to participate in the planned European Unitary Patent despite the Brexite.
The European Unitary Patent and the European Patent Court
For years there has been an effort within all EU member states to create a common European patent. It would not only simplify the filing and validation of a patent throughout the EU, but above all it would also standardise it. This is also important for the jurisdiction of patent proceedings. Because at the moment it is necessary to take a possible patent infringement to court in the respective country in which the patent infringement occurred. This is complicated for several reasons: national law differs, as do various national professions and rules for patent attorneys. A barrister or solicitor known from British patent law is unknown in Germany, for example.
Entry into force of the European Unitary Patent within reach?
It is therefore attractive to participate in the European Unitary Patent and EU-wide jurisdiction that will be created by the European Unitary Patent. However, the territorial validity of the European Unity Patent will only apply to those EU Member States which joined the UPC at the time of the entry into force of the European Unitary Patent. With the ratification of the UPC, Britain can now hope to participate in the European Unitary Patent.
The situation in Germany is still uncertain. As we have already reported, the Düsseldorf lawyer Dr. Stjerna filed a constitutional complaint with the Federal Constitutional Court (BVerfG) in 2017 against the ratification of the Convention on a Uniform Patent Court (EPC) as an initially unknown plaintiff. The BVerfG has not yet decided whether to accept the constitutional complaint for a decision. This can be expected in the next week or months and is a decision that can also have an impact on the UK. If the complaint were to be accepted, the actual ratification by Germany would probably be postponed indefinitely. This might also have consequences for Great Britain: will the UK still be an EU Member State at all at the time of the real entry into force of the European Unitary Patent if the entry into force were significantly delayed by the constitutional complaint in Germany?
Political dimension of the UPC
The further path to the European Patent Court also remains exciting politically. From the British point of view, it is an important question to what extent the national sovereignty of interpretation over jurisdiction must be given in favour of the UPC. And indeed, according to the plan, the European Unity Court should judge disputes on the European Unity Patent on the one hand, but on the other hand also provide the jurisdiction for the European patents that have been in force up to now and will continue to be in force. In this case, national sovereignty of interpretation for patent law is transferred to the EU.
