European Unitary Patent
The UK ratified the Unified Patent Court (UPC) Agreement in April 2018 and has consistently indicated that it intends to participate in the UPC and Unitary Patent (UP). However, there are differing views as to whether it will actually be possible for the UK to remain part of the UPC system after it leaves the European Union (‘Brexit’).
In principle, the UPC will open its doors and the UP will become available to European patent applicants three months after the Agreement comes into force. However, at present it is not clear when this will happen because of the uncertainty surrounding Brexit, as well as an outstanding legal challenge in the German Federal Constitutional Court. These factors have delayed ratification by Germany and hence the coming into force of the UPC agreement.
This page sets out briefly how the European Unitary Patent will work and our view of some of the possible advantages and disadvantages of the UP. It accompanies our pages relating to the UPC and the options for opting out of the UPC. Please refer to these other pages for more information.
At the time of grant, the applicant for a European patent will be able to request an EUP. This will provide a single patent right for the “contracting member states” effective at the time the patent is granted. Other EPC countries can be covered by a normal validation of the European patent in those countries.
The contracting member states are those who have ratified the UPC Agreement at the time of request for the UP. As of June 2017, 14 countries will be covered by the UP. A table of the potential Contracting Member States is given below:
|Countries that have ratified or must ratify (so will be Contracting Member States)||Countries that have not yet ratified|
1: yet to ratify but required to ratify before the UPC comes into force
2: have indicated that they will not ratify before the UPC comes into force
3: Croatia only recently joined the EU and is entitled to accede the UPC Agreement, but has not done so yet
However, the number of ratifications of the UPC Agreement is likely to increase in 2018. Certain countries, such as Slovenia, Lithuania, Latvia, Estonia, and Hungary have indicated that they are ready to ratify the agreement. As such, it is predicted that around 20 countries will be covered by the UP initially.
The UP will always be litigated in the UPC. There is no option to “opt out” an UP from the UPC.
Request for the UP must be done 1 month from publication of grant at the latest. In other words, the request for the UP must be done shortly after responding to the EPO intention to grant (Rule 71(3) EPC) letter. There is no way to convert currently granted European patents into UPs. As such, European patent applications receiving Rule 71(3) EPC letters now will be the first applications likely to have the option to request an UP.
There will be no official fee for the request for an UP. A translation of the European patent application must be filed on request for the UP (namely, 1 month from publication of grant). There will be a single annual renewal fee payable for UP. This is paid to the EPO. The potential translation and renewal fee cost advantages are discussed in more detail below.
If an EUP is requested, then validation of the European patent application must still be done for countries that have not (at that time) ratified the UPC Agreement. Validation will still be required if protection is wanted in, for example, Spain, Switzerland or Norway.
The UP potentially provides a cost saving with respect to the translation requirements and renewal fees.
With respect to translations, the approved text of the European patent will need to be translated entirely into English (if EP is in French or German) or another language of an EU member state (if the EP was in English) during a transitional period.
After 6 years of the transitional period (and at 2 year intervals thereafter up to 12 years in total), the machine translation capability is reviewed. If the machine translations are deemed sufficiently accurate, then the transitional period will be terminated. After that time, no translation will be required to be filed by the applicant.
Therefore, a cost benefit in the transitional period will be realised for proprietors who would normally validate in at least one full translation country (and no longer need to because that country will be covered by the UP).
A single renewal fee is payable, and the fee equivalent to around the top four national renewal fees (that being DE, UK, FR and NL). An estimate of the level of fees is given below. The cost benefit here will only be realised for those proprietors who would normally validate in at least four countries.

Of course, any increase in cost the translation and renewal fee may still be beneficial to gain the additional coverage of the UP (at least 13 countries, including the UK, France and Germany).
A comparison of some of the pros and cons of the UP are provided below.
Potentially reduced translation requirement and cost in the transitional period (of up to 12 years) if normally validate in at least one contracting member states which is outside of the London Agreement
Potentially more translation requirements and costs during transitional period if normally only validate in London Agreement countries
|Reduced translation requirement and costs after transitional period when Google translate is deemed sufficiently accurate||
Potentially higher renewal fees if normally only validate in 3 countries (e.g. UK, France and Germany)
|Potentially reduced renewal fee if normally validate in 4+ of the contracting member states||
Will not include any EU country that has not ratified at the time of request for the UP (such as Spain)
|Covers at least 13 countries including the UK, Germany, France, Austria, Belgium, Bulgaria, Denmark, Luxembourg, Malta, the Netherlands, Portugal, Sweden and Finland||
Does not cover any EPC country that is not a member of the EU (except possibly the UK after Brexit) – therefore still need to validate as before in these countries if desired
The UP will always fall under the jurisdiction of the UPC
Not possible to opt-out of UPC ……………….
|Compensation scheme will be available to reduce the costs of translation for SMEs, natural persons, non-profit organisations, universities and public research organisations that are resident in a contracting member state||Cannot selectively let states lapse during lifetime of patent to reduce renewal costs|
