On July 15, 2022, Montenegro completed the final step towards accession to the European Patent Convention (EPC) by depositing its instrument of accession and became the 39th member state of the European Patent Organization (EPO) on October 1, 2022.
This means that Montenegro is leaving its status as an extension state, which it obtained in 2010, and all patent applications filed on or after October 1, 2022, can be validated as a European patent with effect for Montenegro once they have been granted.
The official admission of Montenegro as a member state is a new milestone in the history of the European Patent Organization.
