Patent Registration in Portugal
Portuguese national patent (patente nacional) prosecution with the INPI — online filing is €125.66, substantive examination €94.26, and a low-cost provisional application (pedido provisório) is €12.57 to secure a priority date. The term is 20 years from filing, maintained by graduated annuities (the 1st–3rd are free, the 4th is €61.97, rising to €867.41 for the 20th). A foreign applicant without a Portuguese establishment generally acts through an official IP agent. A European patent via the EPO (validated in Portugal) is the usual alternative; a utility model (modelo de utilidade) is a faster, cheaper route.

These are the authority’s published lines. Which of them apply depends on your filing — a schedule by headcount, capital or entity type is one line, not all of them — and the applicable line is confirmed before payment, at cost.
