The Unitary Patent & Unified Patent Court

The Unitary Patent and Unified Patent Court provides a new type of European patent and a new system for litigating patents in Europe. It's the realisation of an ambition to unify European patents that dates back almost 50 years, we’re excited it has now arrived!

The unitary patent system realises and ambition that dates back to 1975, when legislation was drawn up to provide a single patent covering all member states of the then European Economic Community (the forerunner of the EU).  That legislation never entered force.  Now, 48 years later, the new European Patent with Unitary Effect (also known as the Unitary Patent or "UP") and its associated court system, the “UPC”, became a reality on 1 June 2023. 

Currently, Unitary Patents cover seventeen EU states including Germany, France, Italy, the Netherlands, Belgium, Austria and Sweden with a single, indivisible patent.  (Future UPs will cover additional EU countries.). Applicants can now obtain a Unitary patent once their European patent application has been examined and granted by the EPO. A unitary patent is available provided that the EP grant date falls after the UPC/UP legislative package entered force on 1 June 2023.

Unitary patents are enforced and litigated at the newly created Unified Patent Court (UPC), which will have ‘central divisions’ in Paris, Munich (and later, Milan), and an appeals court in Luxembourg. In fact, the jurisdiction of the UPC also extends to ‘conventional’ European patents that have been ‘validated’ in one or more participating EU states. However, patentees can “opt-out” their conventional European patents from the jurisdiction of the UPC during a transitional period, which will last for the first seven years of the court’s existence, at least.

Now that the UPC/UP system is available, Mewburn Ellis can obtain unitary patents for our clients, manage the process of opting out their conventional European patents from the jurisdiction of the UPC (if this is desired) and handle litigation at the UPC.

Validations Costs Estimator Mock-Up

Validation Cost Estimator Tool

Easily compare validation routes

We know that it can be challenging to understand whether using the Unitary Patent is the right approach for your business, so we created a Validation Cost Estimator Tool to help you calculate costs for each route. 

Our tool enables you to quickly and easily calculate whether National Validations only or a combination of the Unitary Patent and National Validations is the best option. You can also look at both upfront and ongoing costs to make an informed business decision.

The tool is simple to use, you don't need dates or patent numbers to get results and you can quickly and easily compare both routes side by side and quickly adjust your variables. You can also download your results in a pdf to refer to offline when you need to.

Our Thoughts and Advice

We think that the unitary patent and the Unified Patent Court is a great development in IP and we’re fully behind it. It is a superb opportunity for everyone and we’re delighted to be part of the most exciting development in European patent law for decades. 

These changes provide patent owners with another set of options and additional flexibility to protect their inventions. The unitary patent adds valuable flexibility, but it does make options more complex, it has to be used with care and is not without risks. We’ll help guide our clients in these new decisions to understand what the best approach will be for their businesses. Not only does this give patent owners more choices, it will represent exceptional value because it covers many EU countries with a single patent. This is far more cost effective than using national validations.
The Unitary Patent and the Unified Patent Court are the biggest changes to happen to the European patent system in our professional lifetimes. We’re at the forefront of these changes. We have a great team that are focussed on the unitary patent and Unified Patent Court. Our team is experienced and knowledgeable and the very best at what they do. We’re experts at patent strategy and patent litigation – we will be experts on the Unitary Patent and Unified Patent Court too.
We pride ourselves on being the forward-looking IP firm – we’ve been helping shape IP law for generations. From helping to draft European Law in the 1970s to shaping EPO practice today, we’re embracing the Unitary Patent and the Unified Patent Court with the same entrepreneurial spirit we’ve always had.
