Essential Guide to Trademark Oppositions in Argentina

Protecting Your Rights with Brealant's Expertise

What Is a Trademark Opposition?
An opposition is a formal, reasoned objection to a published application, filed with INPI under Trademark Law No. 22.362 by a party who considers that the new mark harms its rights.
Why Oppositions Matter More Since 2026
Under INPI Resolution P-583/2025, examiners no longer object to marks that are merely similar to earlier ones. Opposition is now the main way owners of earlier marks keep confusingly similar marks off the register.
Protecting Your Position
Whether opposing or defending, a case built on clear evidence of the earlier right and of the risk of confusion gives the best chance of success before INPI.

Clear, Simple Steps Through the Opposition Process

In Argentina, an opposition follows a set sequence: publication in the Boletín de Marcas, 30 calendar days to oppose, a 3-month period for the parties to settle, and then INPI's administrative decision, which either party can appeal to the federal civil and commercial courts. Knowing where a case sits in that sequence is the clearest way to plan next steps.

Safeguarding Your Rights in Argentina — With Brealant by Your Side

An opposition involves real cost, so it is worth weighing the strength of your earlier rights, the risk of confusion and the commercial impact of letting the mark through. Brealant assesses the merits with you before recommending action.

Limitations

What Opposition Cannot Achieve

Opposition is an important tool, but it has real limits

Missed Deadlines
An opposition must be filed within 30 calendar days of publication in the Boletín de Marcas. After that, the usual route is a court action for nullity.
No Effect on Registered Marks
Opposition only applies to pending applications; a granted mark must be challenged through nullity or non-use cancellation instead.
Cost and Time
If the matter does not settle, INPI's own guidance estimates the opposition procedure at around 15 months, and an appeal adds further time.
Burden of Proof
The opponent must show its earlier right and why confusion is likely, with evidence submitted in documentary form.
Partial Outcomes
An opposition may succeed for some of the goods or services only, not necessarily all of them.

Brealant gives you a realistic view of the likely outcome, timeline and cost before you proceed.

What an Opposition Protects

A well-run opposition protects a range of commercial and legal interests

Your Existing Brand
It stops a confusingly similar mark from registering for related goods or services.
Consumer Trust
It reduces the risk that customers confuse your brand with a newcomer.
Market Position
It prevents a competitor from gaining registered rights that could later restrict your own business in Argentina.
A Clean Register
Because INPI no longer checks similarity itself, oppositions are what keep conflicting marks off the register.

Brealant helps you weigh these interests against the cost and time of a contested opposition before you commit.

Timeline for Trademark Opposition in Argentina

Opposition follows a defined, multi-stage process

Publication
Once it passes examination, the application is published in the Boletín de Marcas, opening the opposition period.
Opposition Filed
Within 30 calendar days of publication, the opponent files a reasoned opposition with INPI and pays the official fee.
Settlement Period
The parties then have 3 months to negotiate. The opposition may be withdrawn, or the parties may reach an agreement.
Decision and Appeal
If it is not resolved, the opponent confirms the opposition by paying a further fee, the applicant replies, and INPI decides. Either party can appeal to the federal civil and commercial courts.

An opposition that settles can end within a few months. One decided by INPI takes considerably longer, and an appeal to the courts adds further time.

Understanding Opposition Costs in Argentina — Simplified with Brealant

Costs scale with how far the matter proceeds

Official Fees
INPI charges a fee to file an opposition, and further fees apply if the matter goes on to a decision. Fees are set in UMAPI units, whose peso value changes monthly.
Professional fees
These depend on whether the matter settles early, goes on to an INPI decision or is appealed in court.

Brealant scopes and quotes each stage separately, so you're never committed further than you choose to go.

Frequently Asked Questions

What is the deadline to oppose a trademark in Argentina?

An opposition must be filed within 30 calendar days of the publication of the application in the Boletín de Marcas.

Who can oppose a trademark in Argentina?

Any person or company that considers the application harms its rights can oppose, most often the owner of an earlier similar mark. Foreign owners act through a local agent.

Can the opposition deadline be extended?

No. The 30-day period is fixed, so it is important to monitor the Boletín de Marcas, for example through a trademark watch service.

Can an opposition be settled without a decision?

Yes. The law gives the parties 3 months to negotiate, for example by limiting the goods or services or agreeing on coexistence, and many oppositions end this way.

What happens if I win an opposition?

INPI refuses the application, either in full or for the contested goods or services.

On what grounds can a trademark opposition be filed in Argentina?

Most oppositions rely on an earlier registered or applied-for mark that is identical or confusingly similar. Others rely on a well-known mark, bad faith, or an absolute ground such as descriptiveness.

Why are oppositions more important in Argentina since 2026?

Under INPI Resolution P-583/2025, examiners no longer refuse an application because it resembles an earlier mark. If no one opposes, a similar mark can be granted, so watching new publications is now essential.

What evidence should accompany an opposition in Argentina?

Proof of the earlier right, a comparison of the marks and the goods or services and, where relevant, evidence of reputation or of the applicant's bad faith, all in documentary form.

Can the applicant respond to my opposition?

Yes. If the opposition is not settled or withdrawn, the applicant pays the applicable fee and can reply with arguments and evidence before INPI decides.

What happens if I lose the opposition?

The application proceeds to grant, but either party can appeal INPI's decision to the federal civil and commercial courts within the legal deadline.
