If you intend to protect your invention abroad, please be aware that the patent application or utility model filed in Portugal allows you to use a priority right of 12 months to file the application in another country. If this time limit is respected, the application made abroad will be regarded as having been filed at the same date as the origin application filed in Portugal.
This priority is a great advantage because it allows your application for registration abroad to be treated as if it had been made on the date when protection was sought in Portugal. In this way, it guarantees that no other application that has been submitted during this 12-month period could invalidate the protection of your invention abroad.
It is not mandatory to claim the priority of an application filed in Portugal to apply for the protection of an invention abroad. However, if you wish the European or international application to be valid in Portugal, you must present it at INPI.
