Is there a specific register for the Unitary Patent and what does it contain?

Yes. A Register for unitary patent protection has been set up as an integral but special, i.e. dedicated, part of the European Patent Register already kept by the EPO under Article 127 EPC. For reasons of legal certainty and transparency for users, the Register for unitary patent protection has the same basic structure and functionality as the European Patent Register, but there are some new panel views for the Unitary Patent.

The Register for unitary patent protection contains all the entries expressly listed in Regulation (EU) No 1257/2012. These include, in particular, the fact that unitary effect has been registered and the date of its registration, as well as other procedural information, such as the date of filing of the request for unitary effect, the participating Member States in which the Unitary Patent has effect and the date of filing – and, if applicable, the date of any withdrawal – of a statement on licences of rights. Data on the payment of renewal fees for Unitary Patents and information on any decisions on the validity of Unitary Patents taken by the Unified Patent Court are also shown. For a full list of the entries, see Rule 16(1) of the Rules relating to Unitary Patent Protection.
