The European Patent with Unitary Effect ("Unitary
Patent") already has a longstanding and ambiguous history,
although its underlying legal framework has not yet come into
force. But 2021 brought a considerable push towards implementation
of the Unitary Patent system.
What is the Unitary Patent?
The Unitary Patent is not the same as the European Patent, the
latter being a well-established regime for obtaining patent
protection in various European countries by filing one single
application, including centralised examination, but resulting in
independent national rights in designated countries. While the
Unitary Patent will be based on a European Patent and will also be
administered by the European Patent Office, contrary to European
Patents designating single member states it will have a unitary
effect in all member states of the Unitary Patent system (similar
to the EU Trademark or to Registered Community Designs).
