Portugal specifics
How patent matters work in Portugal
When you ask us to match you with a patent lawyer in Portugal, you benefit from counsel who understands the Portuguese civil-law system and the formal requirements that apply before the judicial and administrative courts. The facts below summarise the rules that shape how your case will be handled.
Reserved practice and Bar registration
In Portugal, only lawyers registered with the Ordem dos Advogados may perform acts reserved to the profession. A patent lawyer must hold Bar registration; practising without it is the criminal offence of procuradoria ilícita under Law 49/2004.
Civil-law court structure
Patent disputes are heard before the judicial courts, currently organised into 23 comarcas with specialised juízos. Appeals go to one of the five Courts of Appeal and cassation to the Supreme Court of Justice in Lisbon.
Court fees expressed in UC
Portuguese court fees are not fixed directly in euros but in a Unidade de Conta (UC), updated annually in line with the social support index. The court fee is calculated by reference to the value and complexity of the case.
Lawyers’ fees freely agreed
Lawyers’ fees in Portugal are freely agreed between the lawyer and the client; there are no binding official tariffs. Fees may be set by written agreement, otherwise assessed according to complexity, time and responsibility.
Legal aid and costs protection
Legal aid under Law 34/2004 may provide exemption from court fees, appointment of a lawyer or phased payment for those who demonstrate economic insufficiency, assessed by the Social Security Institute.
Limitation periods to watch
The general limitation period is 20 years, but shorter periods apply to periodic payments (5 years) and certain claims (6 months or 2 years). A patent lawyer will identify which deadline applies to your matter.
These facts come from official Portuguese sources (Ordem dos Advogados, Diário da República, e-Justice and Portal das Finanças) retrieved in 2025.
Common concerns
What worries people about patent matters in Portugal
You are not alone. These are the concerns we hear most often.
Is my patent really protected?
Without local counsel, it is hard to know whether your filings meet Portuguese form and substance requirements. A patent lawyer reviews your position and flags gaps.
Fearing invalid priority claims
Deadlines for claiming priority or challenging an administrative act are strict. Missing one can be fatal. A lawyer maps every relevant period.
Uncertainty about costs
Portuguese court fees are expressed in a unit of account, not euros, and lawyers’ fees are freely agreed. A lawyer explains what to expect.

Your questions
Patent lawyer in Portugal – FAQs
Do I need a patent lawyer in Portugal to represent me in court?
Yes, if the proceedings require mandatory representation under Article 40 of the Civil Procedure Code, you need a lawyer. Only lawyers registered with the Ordem dos Advogados may perform acts reserved to the legal profession; acting otherwise is procuradoria ilícita.
Can a lawyer from another EU country handle my patent case in Portugal?
EU lawyers may establish in Portugal under their home professional title after registration with the Ordem dos Advogados, or they may be fully admitted after passing an aptitude exam. Your matched lawyer will confirm their registration status.
What does it cost to get matched with a patent lawyer in Portugal?
Our matching service is free. You pay nothing to receive profiles of suitable lawyers. The lawyer’s fees are agreed directly with you and are not governed by official tariffs; they are assessed according to complexity, time and responsibility.
How are court fees calculated in Portugal?
Court costs are expressed in a Unidade de Conta (UC), a unit of account updated annually. The court fee (taxa de justiça) depends on the value and complexity of the case, not only the amount in dispute. A lawyer will explain the expected court fee for your matter.
What is the general limitation period for claims?
The ordinary prescription period in Portugal is 20 years. Shorter periods apply to periodic payments (5 years) and certain claims (6 months or 2 years). A patent lawyer in Portugal will identify the applicable period for your specific claim.
What happens to the losing party’s costs?
As a rule the losing party bears the court costs. The court may also order the losing party to reimburse the successful party’s custas de parte, which include lawyer’s fees up to certain limits. There are no fixed tariffs for lawyer fees.
