After carrying out the centralized procedure for filing an application to register a design, it is valid for a duration of 5 years and renewable for another 5 up to a maximum of 10-25 years depending on the legislation in the individual countries.
Furthermore, if you wish to register a design in a single foreign country, you can do so by maintaining the priority of the filing date of the Italian application, provided that the foreign filing takes place within 6 months and the priority is claimed expressly.
In this case, the duration and judicial protection of the design or model are provided for by the current legislation in the individual foreign country. State-by-state filing is convenient only if the market for products incorporating the design is well circumscribed within individual countries.
