Unified Patent Court

What is the Unified Patent Court (UPC)?

The European Patent Office (EPO) has traditionally provided a centralised application service for the examination and registration of European patent applications across multiple European countries.  However, from an enforcement perspective the patents until this point have been treated individually in each participating country – making ongoing litigation potentially complex and expensive when dealing with multiple territories. 

The Unified Patent Court has been introduced to enable central jurisdiction over all unitary and European patents registered within participating EU Member territories who have ratified the Agreement on a Unified Patent Court (UPCA.  Key impacts of this include:

Jurisdiction for all current and future European patents within participating territories will now fall to the UPC, although these patents will continue to offer independent national rights in those territories where the necessary steps for validation have been taken. (Patents granted by national patent offices are not affected by the introduction of the UPC, meaning national patent litigation can continue to apply alongside UPC litigation.)

In addition to traditional European patents, applicants will now be able to apply for a unitary patent (UP), which offers patent protection across all participating states. The unitary patent is offered in addition to traditional national and European patents.

Following ratification from Germany in February 2023, an initial “sunrise” period of 3 months (starting 1st March 2023) was introduced to allow time for patent holders who wish to opt-out their existing European patents the opportunity to do so before the commencement of the Unified Patent Court Agreement (UPCA) in full from 1st June 2023.

From this point, any infringement and validity actions involving unitary or European patents registered within one of the participating countries can be held under the jurisdiction of the Unified Patent Court (unless opted out of the UPC jurisdiction), although a transitional period of 7 years (extendable up to 14 years) will allow any actions to also be brought before the national courts.

Individual circumstances will dictate which is the best option for each patent, with varying and complex implications dependent on whether the UPC jurisdiction is applied or not.  It is therefore important to fully understand the impact of each option on your patent – both in the short and long term – before taking any decision.

Get to know your business & IP

The first, important stage is to understand your business and the part your intellectual property plays within it. We do this through meetings and reviews of your files and documentation. It is our job to draw out the uniqueness of your design at the very start of the process.

Consideration of prior art

If you are aware of existing intellectual property that may impact your desired goal then we would carry out the necessary patent, patentability and freedom-to-operate searches as required to ensure any potential barriers/issues are identified and incorporated into next steps.

Drafting your documentation

We then prepare the necessary documentation in line with the specific project we are working on. This will vary depending on your particular situation and requirements – for example it could be to map out on paper the unique invention for a patent or to prepare complex files for a revocation case.

Approval of drafting

We will then take the time to ensure you are happy with everything we have drafted before moving to the next stage of dealing with the relevant offices.


Depending on your specific case, we will then submit our documentation to the relevant patent offices and begin proceedings. With new applications we may also request search and examination reports from the relevant offices – before representing you at the various stages of any amendments to your patent specification.

Representation throughout the process before the relevant patent offices

There may be multiple stages of iterations and negotiations with the UPC and various intellectual property offices. Our experienced IP attorneys will represent you during these phases, keeping you informed throughout and advising you on how to proceed, obtaining your approval when appropriate.
