Argentina Rewrites the Rules on Trademark Nullity and Non-Use Cancellation

Argentina has approved new regulations for administrative trademark nullity and non-use cancellation actions before its Trademark Office. The goal is speed and efficiency. The effect is a shift in who can file, which claims the Office will hear, and how these actions fit alongside oppositions.

Who Can Now File a Nullity or Non-Use Action in Argentina?

Anyone who can show a concrete legitimate interest tied to the contested trademark. The old need to prove that one of your own subjective rights was directly affected is no longer strictly required

What might a concrete legitimate interest look like?

The regulations do not list examples, and the Office’s approach will become clearer through early decisions. Situations that commonly support an interest include:

  • Your trademark application in Argentina has been blocked or objected to because of the registered mark.
  • You plan to launch a product or service in Argentina under a similar sign and the registration stands in the way.
  • You trade in the same sector and the registered mark monopolises a term the law says should stay free for all traders.

What evidence should you prepare before filing?

Because the interest must be substantiated at the outset, build your file first:

  1. Copies of your own applications, registrations, or Office actions citing the contested mark.
  2. Proof of current or planned commercial activity in Argentina (contracts, distributor agreements, market entry plans).
  3. Evidence linking your business sector to the goods or services covered by the contested mark.
  4. A clear written explanation of how the registration affects you

Which Nullity Claims Will the Trademark Office Decide, and Which Go to Court?

The Office has drawn a firm line around its jurisdiction. Think of it as two separate lanes.

ADMINISTRATIVE LANE (Trademark Office)
JUDICIAL LANE (Courts)
Marks granted in clear violation of the law.
Grounds based on intrinsic or objective legal prohibitions, meaning defects in the sign itself or in what the law bars from registration.
Goal: a faster, more technical review.
Any claim alleging bad faith.
Any claim alleging trademark piracy.
Applies even if these allegations form only part of the case.

How Does Non-Use Cancellation Work After the Reform?

The core rule has not moved. A trademark can only be challenged for non-use once it has been registered for more than five years.
What is new is the procedural context. The broader standing rule applies, and the action can be brought on its own or inside an opposition proceeding, provided the regulatory requirements are met.

Why does this matter for trademark owners?

A wider pool of potential challengers means unused or partly used registrations are more exposed.

  • Use evidence that is dated, organised, and linked to the registered goods or services is your best defence.
  • Portfolio owners should identify Argentine registrations older than five years and confirm genuine use.

Can Nullity or Non-Use Claims Be Raised Within an Opposition?

Yes. Both actions may be initiated independently or within the context of an opposition proceeding, subject to the regulations.
Illustrative scenario: a foreign company files for its brand in Argentina. A local registrant opposes, relying on an older registration it has not used in years. Under the new framework, the applicant can consider challenging that registration for non-use within the same dispute, instead of running a separate case in parallel.

What Should Brand Owners Do Now?

If You OWN Argentine Registrations
If a Registration BLOCKS Your Brand
Audit marks registered for over five years. Document your legitimate interest now.
Gather and archive proof of use by class. Check the mark’s registration date for non-use eligibility.
Review whether any mark could face an objective-ground challenge. Separate objective grounds from bad faith allegations.
Consider refiling marks where use has lapsed. Consider using an opposition as the vehicle for your challenge.

Conclusion

Argentina has made it easier to start a trademark challenge, while keeping the Office focused on clear, objective legal defects. Owners with unused marks face more exposure. Businesses blocked by stale or invalid registrations gain a faster, more accessible route. In both cases, preparation now pays off
