Trademark Registration in São Tomé and Príncipe: Protect Your Brand Nationwide
Trademark registration in São Tomé and Príncipe is administered by the National Institute of Industrial Property (INPI — Instituto Nacional de Propriedade Industrial), operating under the Ministry of Justice. INPI STP is the competent authority responsible for the filing, examination, publication, and registration of trademarks in the Democratic Republic of São Tomé and Príncipe. The Santomean trademark system follows a first-to-file principle. São Tomé and Príncipe is a Lusophone (Portuguese-speaking) island state in the Gulf of Guinea and a member of the African Intellectual Property Organization (OAPI) framework through its Francophone neighbours, but files trademarks nationally through INPI. The country is also a member of the African Union and the Community of Portuguese Language Countries (CPLP), and its legal framework reflects its heritage as a former Portuguese colony.

Introduction
São Tomé and Príncipe is a small island nation located in the Gulf of Guinea off the western coast of Central Africa, comprising two main islands and several smaller islets. Despite its size, São Tomé and Príncipe occupies a growing strategic position as a commercial gateway to Central and West Africa, with an economy anchored in cocoa exports (the country is renowned for premium single-origin cacao), tourism, fishing, and emerging offshore oil prospects. The country's legal and administrative systems are rooted in Portuguese civil law, and intellectual property registration is administered by INPI STP under a framework informed by Portuguese IP traditions and progressive alignment with African regional IP developments. Trademark protection is essential for businesses, producers, and investors looking to operate, license, or export within São Tomé and Príncipe and the broader Gulf of Guinea and CPLP markets.
Why register your trademark in São Tomé and Príncipe
Exclusive Rights: Grants exclusive legal ownership and the right to use your trademark throughout São Tomé and Príncipe for the registered goods and services, with statutory priority over later conflicting marks.
Legal Enforcement: Enables you to take action against infringement, counterfeiting, and unauthorised use through INPI and the Santomean courts, with civil and criminal remedies available.
Nationwide Protection: Secures trademark protection across the entire territory of São Tomé and Príncipe, including both main islands (São Tomé and Príncipe island) and adjacent territories.
Market Positioning: Strengthens brand identity in one of Central Africa's most distinctive premium product markets, particularly for cocoa, agri-food, and eco-tourism sectors where provenance and branding are critical.
CPLP & African Gateway: A Santomean registration supports brand protection across the CPLP (Community of Portuguese Language Countries) footprint, complementing registrations in Angola, Mozambique, Cape Verde, and Portugal/EU.
Asset Value: A registered trademark is a transferable intangible asset that can be licensed, franchised, pledged, or assigned to support commercial growth, export financing, and corporate transactions.

Trademark registration process in São Tomé and Príncipe
Here is how to register a trademark in São Tomé and Príncipe, step by step.
Here is the step-by-step process followed for trademark registration in São Tomé and Príncipe. Legacy Partners manages each stage on your behalf — from initial clearance through to issuance of the registration certificate by INPI STP.
São Tomé and Príncipe Trademark Search & Application
We begin with a comprehensive availability search across the INPI STP register and international databases, including WIPO (for Madrid designations with comparable scope) and CPLP jurisdiction registers. Once clearance is confirmed, the application is prepared in Portuguese and filed with INPI STP as a national filing. As São Tomé and Príncipe is not a member of the Madrid Protocol, all filings must be made directly through the national office.
Formal & Substantive Examination
INPI STP conducts a formal examination (verifying applicant details, classification, fees, and representation) followed by a substantive examination on absolute grounds (distinctiveness, descriptiveness, deceptiveness, and public order). Office actions, if any, must be responded to within the prescribed deadlines.
Acceptance and Publication
Once the application clears examination, the mark is published in the Official Gazette (Diário da República) of São Tomé and Príncipe, opening a window for third-party opposition.
Opposition Period
Third parties holding prior rights may file an opposition within two (2) months from the date of publication. Grounds include identity or similarity with an earlier registered mark, well-known marks under Article 6bis of the Paris Convention, or bad-faith filing
Registration & Certificate
If no successful opposition is raised, INPI STP registers the mark in the National Trademark Register, issues a Certificate of Registration, and publishes the registration in the Diário da República. The mark is then enforceable against third parties throughout São Tomé and Príncipe.
Validity & Renewal
The trademark is valid for 10 years from the filing date and is renewable indefinitely for successive 10-year periods on payment of renewal fees to INPI STP.
Start your application in a few minutes. Nothing is filed until you approve the written quote.
Documents required for trademark registration in São Tomé and Príncipe
Applicant name & business entity (individual or company, with registered address)
Trademark details (word mark, figurative/logo, combined, or other mark type)
Classes of goods and/or services (Nice Classification)
Power of attorney (if filing through a representative)
Specimen or representation of the mark (for figurative or non-standard marks)
List of goods/services (in Portuguese, clear and precise specification)
Priority documents (if claiming convention priority under the Paris Convention)
Timeline, validity and renewal
How long registration takes
Approximately 12 to 18 months for registration in a straightforward case without objections or oppositions. As a small island developing state, INPI STP operates with limited administrative resources and processing times reflect this context. Applicants are advised to file early and to monitor timelines proactively. Legacy Partners maintains direct contact with INPI STP to track application progress and manage any procedural delays on behalf of clients.
Validity and renewal
The trademark is protected for 10 years from the filing date, renewable indefinitely for further 10-year periods on payment of renewal fees to INPI STP. A grace period may be available after expiry, subject to applicable surcharges. The trademark must be put to genuine use in São Tomé and Príncipe within five years of registration; failure to do so may expose the mark to cancellation on grounds of non-use upon the application of any interested third party before the competent authority.
Governing Law
Trademark protection in São Tomé and Príncipe is principally governed by the Industrial Property Code (Código da Propriedade Industrial), informed by Portuguese civil law traditions and progressively aligned with international IP standards. Enforcement is supplemented by the Civil Code, the Penal Code for criminal enforcement, and Customs regulations for border measures. São Tomé and Príncipe is a member of the Paris Convention (accession confirmed) and the TRIPS Agreement as a WTO member state, ensuring national treatment and priority rights for foreign applicants. The country is not currently a member of the Madrid Protocol, meaning that international filings cannot designate São Tomé and Príncipe directly and all trademark protection must be obtained through a national filing with INPI STP.
Trademark Classes São Tomé and Príncipe (Nice Classification)
São Tomé and Príncipe follows the Nice Classification system, which categorises trademarks into 45 classes — 34 for goods (Classes 1–34) and 11 for services (Classes 35–45). INPI STP permits multi-class applications. Expert guidance from a qualified local agent is essential to ensure the correct class or combination of classes is selected to achieve complete and enforceable protection. Particular attention to classification is recommended for the cocoa, agri-food, fishing, tourism, and financial services sectors that are prominent in the Santomean economy.

What language is used for filing in São Tomé and Príncipe

What is the opposition period after publication?
The opposition period in São Tomé and Príncipe is two (2) months from the date of publication of the application in the Diário da República. Third parties holding prior rights may file an opposition within this window.
Is São Tomé and Príncipe a member of the Madrid Protocol?
No. São Tomé and Príncipe is not currently a member of the Madrid Protocol for the International Registration of Marks. This means that trademark protection in São Tomé and Príncipe cannot be obtained through a WIPO international registration — a direct national filing with INPI STP is required.
Is prior use required before filing a trademark application?
No. São Tomé and Príncipe operates a first-to-file system, and prior use is not a precondition for filing. However, a registered trademark must be put to genuine use within five years of registration to avoid potential cancellation on non-use grounds.
What is the cost of trademark registration in São Tomé and Príncipe?
The total cost depends on the number of classes, the complexity of the mark, and whether office actions or oppositions arise. Please refer to the fee schedule above or contact Legacy Partners for a tailored quotation.
Does a São Tomé and Príncipe trademark protect me in other countries?
No. A trademark registered in São Tomé and Príncipe provides protection only within the national territory. To protect your brand in other African countries, Portugal, Brazil, or other CPLP or Gulf of Guinea states, separate national filings or — where available — regional registrations (such as an EUTM for EU coverage) are required.
Does São Tomé and Príncipe recognise well-known marks?
Yes. As a member of the Paris Convention, São Tomé and Príncipe extends protection to well-known marks within the meaning of Article 6bis of the Convention, even where they are not locally registered.
Can I assign or licence my trademark in São Tomé and Príncipe?
Yes. A registered trademark may be assigned or licensed, in whole or in part. To be enforceable against third parties, such transactions should be recorded with INPI STP.
What makes São Tomé and Príncipe strategically important for trademark registration?
São Tomé and Príncipe's growing importance as a premium cocoa origin, eco-tourism destination, and Gulf of Guinea hub makes brand protection increasingly significant for producers, exporters, and international investors. Its CPLP membership connects it to a network of Lusophone markets across Africa, Asia, and Latin America where brand recognition and cross-border enforcement are commercially valuable.
