The Argentine Patent and Trademark Office (INPI) has issued Resolution 139/2026, introducing changes to trademark prosecution practice in Argentina by eliminating the use of attention calls.

This amendment follows the procedural framework introduced by Resolution P-583/2025, under which trademark applications are substantively examined before publication in the Trademark Gazette.

Under previous practice, third parties could file attention calls to alert the Trademark Office about potential conflicts or objections concerning pending trademark applications. Although these filings were not formal objections, they were used in practice prior to substantive examination to draw the examiner’s attention to potential grounds for refusal. The Examiner could either disregard such arguments or issue an official action based on them.

Resolution 139/2026 establishes that attention calls will no longer be admitted for trademark applications filed as from 1 March 2026. Any third-party challenges must instead be submitted through formal opposition proceedings.

The Resolution also eliminates the automatic conversion of unratified oppositions into attention calls. If the corresponding maintenance fee is not paid, the opposition will lapse and the administrative opposition proceeding will not be initiated.

These measures aim to simplify and streamline trademark prosecution procedures in Argentina under the new examination-before-publication system.
