Portugal: Patent

The INPI also supervises patent filings in Portugal. Applicants may file directly for a national patent or choose to designate Portugal under the European Patent Convention or the PCT.

• Patent protection is valid for up to 20 years from the filing date
• Periodic renewal fees are required to maintain enforceability
• Novelty, inventive step, and industrial applicability are core criteria
• The PCT route offers a streamlined international approach for foreign applicants

Portugal’s membership in both the European Patent Convention and the PCT provides a convenient means to broaden patent coverage.
