You can submit a patent application for inventions that are not yet publicly available. In Portugal, only INPI can grant exclusive rights to inventions.
Protect inventions through patent or utility model
Before making an application, you should ask if you should file a patent or utility model application. Make sure that your invention fits the type of application you want to make, and that this invention is not yet part of the state of the art.

The rights granted by INPI are only valid in national territory. Therefore, to protect your inventions abroad, you must either make an international application or a European application or apply directly in the countries where you want to protect your invention.
