How to Register a Trademark in Argentina (INPI): Steps, Timeline and the 2026 Changes

To register a trademark in Argentina, you file one application per Nice class with the Instituto Nacional de la Propiedad Industrial (INPI), online through its Portal de Trámites. Since 1 March 2026 INPI examines the application before publishing it, publishes it for one day in the Boletín de Marcas, and grants it once 30 calendar days pass without an opposition; the registration lasts 10 years from grant, with a sworn declaration of use due between the fifth and sixth year. The biggest change is what INPI no longer checks: since December 2025 it does not refuse a mark on its own for being similar to an earlier one, so a search before filing, and watching the Boletín after, are now the owner’s job. Argentina is not part of the Madrid System, so foreign owners must register their trademark in Argentina with a national filing.

Verified on 27 October 2026 against the Trademark Law 22.362, Decree 242/2019, INPI Resolutions 123/2019, 288/2019, 583/2025, 63/2026, 139/2026 and 297/2026 (texts as published in the Boletín Oficial), INPI’s own pages and WIPO’s list of Madrid members. Each row below names its source. Fees change often, so this page does not list them.

What changed at INPI in 2025 and 2026

Four INPI resolutions rewrote the procedure for new applications. Most guides still describe the old order (publication first, examination later) and the old opposition stage with a separate evidence period.

Resolution	In force	What changed	What it means for you
583/2025 (Boletín Oficial, 11 December 2025)	Art. 1: from publication, also for pending files. Art. 2: from 1 March 2026	INPI examines only absolute and public-order grounds. Similar earlier marks (art. 3 b of the law), misleading marks (d), a person’s name or portrait without consent (h) and activity designations (i) are assessed only if a third party raises them. Examination now comes before publication, and the mark is granted after 30 days without opposition	A conflicting mark will not stop your application unless its owner opposes, and your own mark is not protected unless you oppose. Search before filing
63/2026 (26 February 2026)	1 March 2026	Office actions and notices go to your electronic account (sede electrónica); final decisions are still published in the Boletín de Marcas. Deadlines run from the day after notification; the old 30-day suspension is gone	Deadlines start sooner. Someone has to read the Portal account every day
139/2026 (6 May 2026)	Applications filed from 1 March 2026	No more "llamados de atención", the informal warnings third parties used to file after publication. The only way to object is a formal opposition	If you own a mark, missing the 30-day opposition window leaves you with court action only
297/2026 (10 August 2026)	From its publication in the Boletín de Marcas, for oppositions against applications filed from 1 March 2026	New opposition procedure: no separate evidence stage, evidence goes with each side’s brief, 15 business days for each side to pay and file, briefs signed by a lawyer or registered IP agent, and an applicant who does not pay is refused	Have your evidence of use and rights ready before an opposition starts

Applications filed up to 28 February 2026 keep the previous rules for llamados de atención and oppositions (Res. 139/2026, art. 4; Res. 297/2026, art. 4).

How to register a trademark in Argentina, step by step

1. Search first. INPI’s free search only finds identical characters; phonetic searches are a paid service (INPI, "Averiguá si tu marca está registrada"). Because INPI no longer refuses similar marks on its own, a trademark search in Argentina that covers similar and phonetic matches is the only way to know who might oppose you.
2. Prepare one application per class. Name and address of the applicant, the mark, the class and the specific goods or services. INPI’s form includes the TMclass list; using it is optional, but INPI’s fast track requires it (see below). Never select "toda la clase": the application is refused (Res. 288/2019).
3. File online. Filing is electronic only, through the Portal de Trámites, and requires an Argentine tax login (Clave Fiscal level 2 with ARCA) (Res. 123/2019, art. 9; INPI). The day and hour of filing set your priority (Law, art. 8). If you filed the same mark in another Paris Convention country in the last 6 months, you can claim that date.
4. Examination. INPI checks form and absolute grounds before publication. A formal defect must be fixed within 10 business days (Decree 242/2019, art. 12). A substantive objection must be answered within 30 calendar days (art. 15), extendable automatically by 10 and then 5 calendar days with a fee (Res. 123/2019, art. 6), and the answer needs a lawyer or registered IP agent (INPI FAQ).
5. Publication and opposition. The application is published for one day in the electronic Boletín de Marcas, which comes out on Wednesdays. Anyone with a legitimate interest can oppose within 30 calendar days (Law, art. 13).
6. Grant. With no opposition, INPI grants the mark once the 30 days pass (Res. 583/2025, art. 2). The 10-year term counts from that grant.
7. If someone opposes. The parties have 3 months to settle, mediation included (Law, art. 16). Then the opponent has 15 business days to keep the opposition alive by paying the fee and filing all its evidence, and you have 15 business days to pay your fee and answer with yours; if you do not pay, the application is refused. Each side may add final arguments within 10 business days, and INPI decides (Res. 297/2026, annex arts. 1, 2 and 6). Its decision can be appealed to the federal civil and commercial court of appeals within 30 business days (Law, art. 17).

How long it takes

INPI’s own page gives two figures for the new procedure: 60 days if you choose your goods from the TMclass drop-down list, do not claim priority and do not file through a business agent (gestor), and 6 months otherwise, provided there are no objections or oppositions. These are INPI’s stated times, not measured averages: INPI has not yet published statistics for applications filed under the procedure that began on 1 March 2026.

Situation	What adds time	Source
Clean application, fast track	60 days stated by INPI	INPI, "Registrar una marca"
Clean application, standard	6 months stated by INPI	INPI, "Registrar una marca"
Office objection	Up to 30 calendar days to answer, plus 10 + 5 days of paid extensions, plus INPI’s review	Decree 242/2019, art. 15; Res. 123/2019, art. 6
Opposition	3 months to negotiate, 15 + 15 business days of briefs, 10 for final arguments, then INPI’s decision	Law, art. 16; Res. 297/2026
Appeal	30 business days to file, then a court case	Law, art. 17

INPI also recommends waiting at least 30 days after publication before relying on a new mark, to see whether anyone opposed it (INPI FAQ).

Foreign applicants: what you need

• A national application. Argentina is not on WIPO’s list of 117 Madrid members (status 8 July 2026), so an international registration cannot designate it. We explain the consequences in No Madrid Protocol in Argentina. Your protection is national only (INPI FAQ).
• An address in Buenos Aires. Applicants who live abroad must set a special address in the City of Buenos Aires, in addition to the electronic one (Decree 242/2019, art. 10). That address counts for notices and jurisdiction (Law, art. 11).
• A way to file and pay locally. Filing requires the Argentine tax login, and INPI says fees must be paid through national platforms and that a foreign applicant may need a locally based representative (INPI FAQ).
• A lawyer or agent at key moments. An agent is not mandatory to file, but you need a lawyer or registered IP agent to answer a substantive objection and to sign opposition briefs (INPI FAQ; Res. 297/2026, annex art. 3).

In practice, that is why most foreign owners file through a local representative. Ours files with a simple power of attorney (signed, no notarization or legalization), which can be sent after the application is filed.

After registration: use, renewal and the 6-month grace period

• Declaration of use: after the fifth anniversary of the grant and before the sixth ends, the owner files a sworn declaration of use (Law, art. 26). Not filing it creates a presumption of non-use (Decree 242/2019, art. 26), late filing costs an extra fee for each year, and renewal is blocked until it is filed, for marks granted since 12 January 2013 (Res. 123/2019, arts. 2-4).
• Non-use: INPI can cancel a mark, in whole or for some goods, if it was not used in Argentina in the 5 years before the cancellation request (Law, art. 26).
• Renewal: possible from 6 months before to 6 months after expiry; the months after expiry carry an extra fee (Res. 123/2019, annex art. 4; INPI). A renewal can narrow the list of goods but never add to it (Decree 242/2019, art. 5). Our trademark renewal in Argentina service handles it.

Checklist before you file in Argentina

1. Run a search that covers similar and phonetic marks, not just identical ones.
2. Choose your classes; budget one application per class.
3. Write specific goods and services (TMclass terms if you want the fast track); never "all goods in the class".
4. Arrange the Buenos Aires address and a representative who can file, pay and read the Portal account every day.
5. Put in your calendar the 30-day opposition window after publication, and the declaration of use between years 5 and 6.
6. If you own earlier marks in Argentina, watch the Boletín de Marcas: since 2026, opposing within 30 days is the only administrative way to stop a similar mark.
