Practical Full Guide to National Trademark Registration in Portugal

Before submitting a national trademark application to INPI Portugal, every applicant must complete two unique pre-submission verifications that differ entirely from general Portuguese trademark law articles and non-EU registration systems such as India and the UAE. The first compulsory procedure is official trademark database retrieval via INPI’s English-language e-portal, covering all active, pending, lapsed and cancelled national trademarks across mainland Portugal, Madeira and the Azores. Basic word mark searches are free of charge, while comprehensive figurative/logo searches with an official written comparative report cost EUR 60. The search report records identical or confusingly similar marks registered for matching goods and services, serving as core evidence to avoid post-filing substantive rejection and opposition disputes.

Second, applicants must classify goods and services strictly under the 11th Edition of the Nice Classification, the sole version accepted by INPI as of 2026. Outdated 10th Edition descriptive terms will trigger an immediate formal examination defect notice without partial amendment opportunities. All applicants fall into two distinct categories: Portuguese resident individuals or legal entities, and foreign applicants without a fixed business premise or tax domicile within Portuguese territory. Overseas companies and natural persons without local residency must engage an INPI-licensed industrial property attorney and submit an unnotarised power of attorney at the time of filing; delayed POA submission will suspend the entire application workflow indefinitely until complete documents are uploaded to the digital system.

Joint applications by two or more unrelated enterprises are permitted, yet the final registration certificate lists all co-applicants as equal co-proprietors. If co-owners cannot reach an agreement on trademark renewal, licensing or assignment in the future, commercial courts are the sole dispute resolution channel; INPI does not provide administrative mediation services for ownership conflicts.

2. Dual Filing Modes & Tiered Official Fee Standards

Portugal maintains parallel digital e-filing and offline paper submission channels with differentiated pricing regulated by INPI 2024 Service Tariff Circular No. 09:

1.  Online E-Filing (Official Recommended Channel): Applicants log into INPI’s official industrial property portal, upload digital materials and complete payment via bank transfer, credit card or Multibank national payment gateway. This channel receives a 30% discount on base filing fees. Single-class online fee for individuals: EUR 120

a.  Single-class online fee for corporate entities: EUR 240

2.  Offline Paper Filing: Hard-copy TM-PT application forms submitted to Lisbon headquarters or regional INPI service centres. Paper applications impose a mandatory 30% surcharge on all base official fees, resulting in EUR 156 per class for individuals and EUR 312 per class for companies.

A dedicated accelerated review scheme named Prioridade Rápida (Fast Priority Trademark Examination) was launched in early 2023 for SMEs and startups registered under Portugal’s national SME support scheme. Qualified applicants pay an extra EUR 320 per class to reduce the standard 90-day substantive examination period to only 20 working days. Large multinational enterprises without local SME certification cannot access this fast-track procedure, regardless of export volume targeting non-EU markets such as India and the Gulf nations. All official fees are non-refundable, even if the application is rejected or voluntarily withdrawn after formal submission.

The full mandatory document checklist for each multi-class or single-class national application includes: fully completed TM-PT bilingual Portuguese-English electronic form, high-resolution trademark specimen (minimum 5cm × 5cm, CMYK colour value labels required for colour marks), applicant identity or corporate tax registration certificate, unnotarised POA (exclusively for foreign filers), SME/Startup registration certificate (for fast priority requests), and itemised goods/services list compliant with the 11th Nice Classification.

3. Four-Stage Statutory Registration Workflow with Fixed Response Deadlines

After successful fee payment confirmation, all trademark applications follow four sequential legally binding procedural stages with non-extendable reply windows, fully separated from the simplified workflow of GCC and South Asian trademark offices:

Stage 1: Formal Examination (Maximum 15 Working Days)

INPI examiners audit document integrity, agent licensing validity, Nice classification compliance and trademark specimen specifications. A single M-1 deficiency notification is issued for incomplete materials, granting a one-time 20-day correction period. Failure to rectify all defects within the deadline results in automatic deemed abandonment with no right of administrative appeal.

Stage 2: Substantive Examination (90 Calendar Days Standard / 20 Working Days Fast Priority)

Examiners assess absolute refusal grounds under Article 123 and relative conflict grounds under Article 124 of Decree-Law 50/2022. If prior conflicting trademarks or statutory violations are identified, an official Examination Report (Relatório de Exame) is sent to the appointed local attorney. Applicants must submit a detailed counterstatement with visual distinctiveness comparison evidence within 30 calendar days of receiving the report; silence or overdue replies lead to complete dismissal of the trademark application.

Stage 3: Publication in the Official Industrial Property Bulletin & 2-Month Opposition Term

Applications clearing substantive review are published on INPI’s weekly digital Industrial Property Bulletin. Unlike India’s four-month opposition period or the UAE’s 30–60 day window, Portuguese national law enforces a rigid two-month opposition term calculated from the bulletin’s publication date. Any natural person or legal entity holding verifiable commercial interests may submit a TM-Opp form with supporting prior-right documentary evidence. Opposition hearings are held via remote video conference by mutual written request of both opposing parties.

Stage 4: Issuance of Trademark Registration Certificate

If no oppositions are filed or all opposition claims are fully dismissed, INPI completes the registration formalities within 30 working days. A digital electronic registration certificate is issued automatically; applicants may request a physical hard-copy certificate by paying an additional EUR 45 administrative production fee. The trademark protection term lasts for 10 consecutive years, calculated strictly from the original filing date, rather than the publication or registration grant date.

4. Post-Registration Administrative Formalities Unique to Portuguese National Filings

After receiving the registration certificate, trademark proprietors may apply for three categories of post-registration amendments via official Form TM-M, each subject to independent regulatory restrictions not covered in the general Portuguese Industrial Property Code overview:

1.  Minor Trademark Modifications: Small adjustments to colour saturation, font layout or graphic proportion are permitted. Any material alteration to core distinctive verbal or figurative elements is prohibited; applicants must submit an entirely new TM-PT national application instead of modifying the existing registration.

2.  Change of Proprietor Address or Legal Representative: If the trademark owner relocates its registered tax address or replaces the INPI-licensed attorney, Form TM-M must be filed within one month of the change taking effect. Unrecorded address updates render all official INPI notices legally undeliverable, potentially triggering non-use cancellation risks due to missed renewal reminders.

3.  Partial Deletion of Goods and Services: Registrants may remove selected sub-items within a registered Nice classification class, but no new goods or service descriptions can be added to an existing registration at any point during the 10-year protection cycle.

Two core post-registration compliance obligations apply to all national trademark holders: First, continuous use monitoring to avoid Article 141 five-year non-use cancellation. Any third party can file a cancellation petition if the mark lacks genuine commercial deployment across Portuguese territory for five consecutive years without legitimate justifications such as factory suspension or EU product certification delays. Registrants must permanently retain sales invoices, domestic e-commerce listing screenshots, retail packaging photos and local media advertising receipts as official use evidence throughout the full 10-year validity period. Second, voluntary EU customs IP recordation supplementary filing. Proprietors may submit their INPI trademark registration certificate to Portuguese Tax and Customs Authority (AT) to activate automatic cargo screening for counterfeit imports entering all national border ports, an optional independent procedure separate from core trademark registration formalities.5. EU Union Trade Mark vs Direct Portuguese National Filing for Cross-Border Brands

Foreign exporters targeting both EU single market and non-EU markets such as the Gulf and India have two distinct filing options, with clear drawbacks for EUIPO Union Trade Mark designations compared to standalone Portuguese national applications:

1.  Direct National TM-PT Filing: Full independent control over counterstatement arguments during examination and opposition procedures, eligibility for the domestic Fast Priority accelerated review scheme, direct communication channels with INPI local examiners, and no mandatory reliance on a base home-country trademark registration.

2.  EUIPO Union Trade Mark (EUTM): Lower aggregate filing costs for brands operating across multiple EU member states, yet Portugal’s INPI Fast Priority fast-track service is unavailable for all EUIPO Union Trade Mark applications. All examination objections issued against Portuguese goods/services specifications must be relayed exclusively through EUIPO’s central Alicante bureau, creating communication delays ranging from 1 to 4 months. Additionally, EUTM holders cannot submit partial goods deletions or minor trademark rectifications directly via Portugal’s domestic INPI portal; all post-registration amendments must be processed entirely through the EUIPO official platform in Spain.

For small and medium-sized merchants only selling products within Portugal’s domestic market, INPI’s certified IP attorneys universally recommend standalone national multi-class filings. Large multinational groups covering 10 or more EU jurisdictions often adopt a hybrid strategy: EUIPO Union Trade Mark for pan-EU general coverage plus independent Portuguese national fast-track registration for core product lines requiring rapid market launch in mainland Portugal, Madeira and the Azores.

6. Common Procedural Mistakes Leading to Automatic Application Rejection

Three recurring filing errors frequently result in full rejection of foreign applicants’ Portuguese national trademark submissions, issues rarely encountered in GCC or South Asian trademark registry systems:

1.  Submitting blurry, oversized colour trademark specimens without mandatory CMYK colour parameter annotations;

2.  Copying abbreviated, non-compliant Nice Classification item descriptions from third-party commercial websites instead of adopting the official full terminology published on INPI’s database;

3.  Appointing unlicensed freelance translators or overseas consultants instead of formally INPI-registered industrial property attorneys to handle foreign applicant filings.

Pre-filing official database searches and professional attorney document review eliminate over 80% of these avoidable rejection risks, reducing wasted time and non-refundable official filing fees for cross-border export enterprises supplying Portugal’s retail and e-commerce industry.
