Estonia ratifies the UPCA

4 August 2017

Estonia has ratified the Agreement on a Unified Patent Court (UPCA). Estonia’s ratification means that the geographical protection provided by the Unitary Patent (UP) upon implementation will cover to at least 15 countries.

The complete list of countries to have ratified the UPCA can be found here but must also include the UK and Germany before the Unitary Patent Package can come into force.

German ratification is currently stalled, whilst a constitutional complaint is evaluated Germany’s Federal Constitutional Court. The extent to which that complaint will delay the implementation of  Unitary Patent Package is still unknown.
