Argentina (AR) — civil law.

Nothing on this page describes United States practice. There is no certificate sold to an investor, no administrative sale of land for unpaid tax, and no redemption window after a subasta judicial in Argentina. If you arrived carrying US assumptions, read falsos-amigos first.

Ley 22.362 — Marcas y Designaciones

Ley 22.362 is the national trademark law. Its enforcement authority is the INPI (Ley 24.481 art. 90). It was substantially amended by Ley 27.444 (BO 18 June 2018), which moved oppositions, nullity and caducidad into an administrative procedure at INPI with direct appeal to the federal civil and commercial appeals court. Six rules decide what an auction buyer gets. Ownership arises only by registration (art. 4). A registration lasts ten years and renews only if the mark was used in the prior five (art. 5). A transfer binds third parties only once INPI records it (art. 6). The sale of a fondo de comercio carries the mark unless excluded (art. 7). Co-owners must act jointly to transfer or renew (art. 9). And a mark can be struck off for non-use over the five years before a request (art. 26), with a sworn use declaration due between the fifth and sixth year after grant. Two InfoLEG notes record 2025–2026 INPI changes to examination. Resolución INPI 583/2025 (BO 11/12/2025) limits ex officio examination of new applications to absolute and public-order grounds, leaving art. 3 incs. b, d, h and i to third-party challenge. It also reorders the art. 10 ff. procedure from 1 March 2026. For buying, licensing and the live CSJN-portal trademark auctions, see marcas-y-propiedad-intelectual.

The opening section is open to everyone. The procedure in detail — statutes, deadlines, who may bid, and what the record does not say — is behind a free account.

We ask for one because writing these from primary sources is slow work, and knowing who relies on it tells us which country to do next.
