How to Register a Trademark in Argentina: Complete 2026 Guide

Registering a trademark in Argentina is a fundamental step in protecting your company's commercial identity. This guide explains, step by step, how to complete the process before the National Institute of Industrial Property (INPI).

Why register a trademark?

Trademark registration grants the owner the exclusive right to use a distinctive sign to identify products or services. Without this registration, any third party may use a similar name or logo, creating market confusion and harming your business.

Step 1: Prior art search

Before filing an application, it is essential to conduct a thorough search of existing trademarks. This search identifies identical or similar marks that could trigger an opposition to registration or give rise to future conflict.

The search covers not only identical marks but also those that may be considered phonetically, visually, or conceptually similar.

Step 2: Classification of goods and services

Trademarks are registered in relation to specific goods or services, organized under the Nice Classification. It is important to select the classes that correctly correspond to your commercial activity.

A mark registered in one class does not automatically protect goods or services in other classes. Your registration strategy should therefore cover all areas relevant to your business.

Step 3: Filing the application

The application is filed with the INPI through a fully digital process. It must include the applicant's details, a reproduction of the mark, a specification of the goods or services, and payment of the applicable fee.

Step 4: Examination and publication

The INPI conducts formal and substantive examinations to verify that the trademark application is registrable and that the application form meets the required formal criteria. Once approved, the application is published in the Trademark Bulletin, opening a 30-day period during which third parties may file oppositions.

Step 5: Resolution

If no oppositions are filed, if they are rejected, or if any official actions are addressed to, the Trademark Office registers the trademark and issues a digital certificate of registration for a ten-year term, renewable indefinitely.

Addressing potential obstacles

An application may receive objections from the Trademark Office – office actions - or oppositions from third parties, either of which interrupt the registration process. Official actions must be replied by trademark attorneys or agents, while oppositions must be addressed through negotiation between the parties or the administrative opposition proceeding.

Without specialised intellectual property knowledge and experience, it is very difficult to overcome these obstacles, and filed marks may be refused.

Conclusion

Trademark registration is an investment in protecting your business. Although it is possible to complete the process independently, professional specialised advice significantly increases the likelihood of success and helps avoid costly mistakes.
