What is the Unitary Patent, and how do I get one?

The Unitary Patent will be a single patent right, obtained via the European Patent Office, covering all EU Member States which have ratified the agreement at the patent grant date. (As of June 2022, the participating countries are Belgium, Bulgaria, Denmark, Estonia, France, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Austria, Portugal, Slovenia, Finland and Sweden, and will further include at least Germany by the date of entry into force)

The request to convert the European patent into one having unitary effect, instead of a bundle of national rights in the participating countries, is made by the proprietor on grant of the patent to the European Patent Office (EPO). Even if other countries join the system after the grant of the patent, they will not be added to the Unitary Patent and if protection in those countries is required then the European Patent will need to have been validated in those countries at grant, in the same way as for a classical European Patent (i.e. as under the current system).

A unitary patent will be a single indivisible patent, rather than a bundle of national patents. It will have the same claims for all participating Member States and must be valid in all states. The UP will offer protection in many countries for a lower total cost, as compared to the current bundle system. Further, a single enforcement action, effective in many countries, should make litigation cheaper too.

A unitary patent may only be limited, transferred or revoked, or lapse in respect of all the participating Member States. However, a unitary patent may be licensed in respect of the whole or part of the territories of the participating Member States.

Note that the Unitary Patent will not be compulsory. It will be possible to use the classical EPC route even for Member States which participate in the Unitary Patent system. The classical route may remain attractive because, compared with a classical European patent, for the Unitary Patent:

  • Costs will be higher if you only usually validate in a few countries (<3).
  • There is a single renewal fee; it is not possible to drop countries to "prune" portfolio and reduce costs by not paying a renewal fee for a given country.
  • Patent is vulnerable to a single knock out across member states, and from people in countries who previously would not have taken any interest because you did not validate in that/those country/countries.
  • Prior art that is currently only relevant in one state would invalidate the patent in all member states of the Unitary Patent.
  • Cannot opt-out of the UPC (if you wanted to).

Recent Case Reports

No language change at Central Division
08 October 2026
Proceedings before the UPC Central Division must be conducted in the language in which the patent was granted. There is no legal basis to change that language. In a revocation action concerning a German-language patent, the Paris Central Division rejected a request to switch the language of proceedings to English, and also rejected a subsidiary request to allow written submissions in English and hold the hearing in English, holding that Article 49(6) UPCA permits no derogation and reflects a deliberate legislative choice.
Criteria for obtaining an order to produce evidence under Rule 190
07 October 2026
This appeal judgment clarifies that Rule 190 orders to produce evidence require three cumulative conditions: specificity, necessity and proportionality, and cannot be used for fishing expeditions. The Court of Appeal confirmed that first instance judges enjoy a broad margin of discretion when assessing such requests, and upheld the order requiring production of two fabric samples for ballistic testing. Both the appeal and the cross-appeal were dismissed.
Court of Appeal focuses on the technical effect to determine added matter
30 September 2026
The Court of Appeal provided guidance on their approach to assessing added subject matter, highlighting that the technical effect underlying the invention and how the claimed and unclaimed features contribute thereto is central to the analysis.
