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

UPC Court of appeal issues final decision, despite no finding on infringement at first instance
30 March 2026
In Rematec v Europe Forestry, the UPC Court of Appeal overturned the Mannheim Local Division’s revocation of the patent and, applying Article 75(1) UPCA, issued a final decision on both validity and infringement despite no infringement finding at first instance. The Court adopted a narrower, description‑led approach to claim interpretation, confirmed the patent’s validity, found infringement, and granted final remedies without referring the case back to the Court of First Instance.
Litigation insurance as security for costs
30 March 2026
In Syntorr v Arthrex, the UPC Court of Appeal clarified that while litigation insurance is not itself a form of security under Rule 158 RoP, it is a relevant factor when deciding whether security for costs should be ordered at all. By failing to consider the claimant’s insurance policy, the Munich Local Division wrongly exercised its discretion. The Court set aside the €2 million security order and confirmed that insurance can mitigate concerns about cost recoverability.
National law applies to claims for loss of profit if the events occurred before the UPC came into force
30 March 2026
In Fives v REEL, the Hamburg Local Division of the UPC dismissed a standalone damages action despite prior findings of infringement. Although the UPC was competent to assess damages, the court held that national law applied because the relevant events pre‑dated the UPC’s entry into force. Applying German law, the court found that the claimant had not proven causation or lost profit, highlighting the demanding evidentiary burden for price‑reduction damages claims and the importance of substantiating counterfactual tender outcomes.
