The owner of an Italian patent application who intends to protect his invention abroad can extend his own patent in one or more foreign countries.
To do this, he must file a patent application with the National Patent Office of each country of interest.
Foreign patent applications are completely independent both during examination or granting and regarding the provisions that must be complied with in order to be valid.
Patent protection in individual countries is compulsory when the owner intends to extend the protection of an Italian patent to countries that have not signed the International Treaties allowing for cumulative registration. On the contrary, it is recommended to reduce costs when the owner decides to extend the protection of an Italian patent to one or few countries that have signed the International Treaties.
