New Rules for the Administrative Resolution of Trademark Oppositions in Argentina

INPI Resolution No. P-297/2026 approves new Regulations on the administrative proceedings for the resolution of trademark oppositions in Argentina.

The new framework is intended to simplify, automate and expedite opposition proceedings and applies to oppositions against trademark applications filed on or after March 1, 2026.

Key Changes Introduced by the New Regulations

• Full automation: Manual procedures are reduced, and the various procedural stages are digitized.
• Elimination of a separate evidentiary stage: The previous independent period of up to 40 business days for the submission of evidence has been eliminated. Evidence must now be submitted together with the parties’ initial pleadings.
• Final submissions: A common and optional period of 10 business days is introduced, allowing the parties to submit their final arguments before the final decision is issued.
• Alternative dispute resolution mechanisms: The Regulations allow the parties to expressly notify the INPI of the commencement of mediation or conciliation proceedings.
• Maintenance of the opposition: Once the statutory term has expired, the opponent is notified of a non-extendable period of 15 business days to state whether it wishes to maintain the opposition by paying the applicable official fee.
