Argentina Updates Trademark Opposition Rules

Argentina's National Institute of Industrial Property (INPI) adopted new regulations for administrative trademark opposition proceedings through Resolution No. 297/2026. The resolution was published in the Official Gazette and took effect on August 12, 2026.

The updated rules simplify and expedite opposition stages while aligning procedures with INPI's existing framework. Key changes include allowing parties to raise cancellation claims within opposition proceedings.

The measures apply to oppositions filed against applications submitted on or after the effective date. Officials aim to reduce processing times and improve efficiency for applicants and opponents.

Practitioners note the changes modernize administrative handling without altering substantive trademark law. Similar procedural reforms have been implemented in other jurisdictions to manage growing caseloads.

The resolution includes an annex detailing the revised procedural steps and timelines.
