Unitary Patent vs National Validation Cost Calculator

A: A Unitary Patent gives uniform protection across participating EU states through a single request made after grant of a European patent, with one annual renewal fee paid centrally to the EPO. It replaces the need to validate and separately renew a classic European patent in each of those states.

A: 18 states have ratified the Unitary Patent and UPC agreement: Austria, Belgium, Bulgaria, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Portugal, Romania, Slovenia and Sweden. Several more EU states, including Ireland, Czechia, Greece, Hungary, Cyprus and Slovakia, have signed but not yet ratified. Spain, Poland and Croatia are not currently participating. The UK, Switzerland, Norway and Turkey cannot join, as they sit outside the EU.

A: No. The Unitary Patent’s renewal fee was set to roughly match the combined cost of validating in Germany, France, the UK and the Netherlands, so it tends to offer better value once you need protection in four or more participating states. For narrower strategies, particularly one or two states, national validation is often cheaper, since you avoid paying for coverage you don’t need elsewhere.

A: No. The UK, Spain, Switzerland, Norway and Turkey, among others, sit outside the Unitary Patent system entirely. If protection is needed there, national validation is the only route, and can be run alongside a Unitary Patent for your other target states.
