Costa Rica to become EPO validation state
A validation agreement has been signed between the European Patent Office and Costa Rica. It was signed on 13 December 2024 and is expected to enter into force shortly, making Costa Rica the seventh country to become a "European" validation state. Once the agreement comes into force, European Patents can be validated in Costa Rica and have the same effect as a national patent in that territory.
Validation states (which include Cambodia, Morocco, Moldova, Tunisia and Georgia) must be selected around the time of filing of a European patent application. A validation agreement was signed with Laos in 2024 and is expected to come into force soon. The date of the agreement coming into force determines availability of the particular validation state. Therefore after the agreement comes into force, only newly filed European patent applications and PCT applications will have access to Costa Rica as a validation state.
