The Unitary Patent
A Unitary Patent provides patent protection in the EU countries that are part of the scheme.
The patent application is submitted and processed as usual at the EPO, i.e. nothing has changed in the application processing phase. After a European patent has been granted, the patent holder can claim unitary effect for the patent within one month. This means that the patent will apply in the countries that are part of the scheme. There are currently 17 EU members.
Unitary effect means that the patent has one and the same protection with the same legal consequences in all EU countries where the unitary patent is valid.
You pay the annual Unitary Patent fee to the EPO. The EPO also manages the unitary patent register.
Even if unitary effect is required, the patent holder can also validate the European patent in the countries that are not part of the Unitary Patent scheme. Instead of requiring a unitary effect, it is also possible to only validate in the countries where you want to have a patent, as before.
Be aware that a Unitary Patent will not apply in Norway. A European patent must be validated in Norway for it to be valid here.
