Argentina simplifies trade mark opposition procedure

On 10 August 2026, Argentina’s INPI published Resolution 297/2026, introducing new rules for the administrative resolution of trade mark oppositions. The procedure applies to oppositions filed against new trade mark applications submitted from 1 March 2026 onwards, while earlier applications will continue under the previous rules.

The new procedure automates certain stages and concentrates the submission of evidence, removing the separate evidence stage. Evidence should generally be submitted together with the opponent’s arguments or the applicant’s response. It also introduces a voluntary 10-working-day period for final arguments and allows parties to inform the INPI where mediation, conciliation or another alternative dispute resolution procedure has been initiated. Applicants and opponents should therefore prepare their evidence at an earlier stage and check which procedural regime applies according to the filing date of the application.
