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.

INPI — Instituto Nacional de la Propiedad Industrial

The INPI is a national, autonomous body (organismo autárquico, con personería jurídica y patrimonio propio). It was created by Ley 24.481 art. 90 as the enforcement authority for the patent law, the trademark law (Ley 22.362), Ley 22.426 and Decreto-Ley 6673/63 on industrial designs. It sits in the economy ministry. Its title register is the only place where a court-sold marca or patente becomes the buyer’s against third parties. A trademark transfer “es válida respecto de terceros una vez inscripta” (Ley 22.362 art. 6). A patent assignment “deberá ser inscripta en el INSTITUTO NACIONAL DE LA PROPIEDAD INDUSTRIAL” (Ley 24.481 art. 37). Transfers are filed online with CUIT and clave fiscal level 2, with a service standard of 15 business days. INPI states that no medidas cautelares may weigh on the transferor or on the mark, so the selling court’s oficio must clear them. Court orders go first to INPI’s Departamento de Oficios y Medidas Cautelares. Since 29 May 2026 transfers are governed by a new Reglamento para la Toma de Razón de Transferencias de Dominio y Cambios de Rubro (Res. INPI 162/2026). Trademark files are public and freely accessible (Ley 22.362 art. 22), so the due-diligence search costs nothing but time.

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.
