The Argentine Trademark Law No. 22,362 and complementary regulations establish several prohibitions that must be taken into account before filing an application. Below is a summary of the main categories of non-registrable signs.
Signs That Are Not Considered Trademarks:
Article 2 of the Law enumerates the signs that lack distinctiveness and therefore cannot be registered as trademarks:
Generic or descriptive terms: words that directly designate the product or service or describe its nature, function, or qualities.
Trademarks that have become generic: signs that, although originally distinctive, have entered into common use and lost their capacity to function as trademarks.
The necessary shape of a product: the usual or functional shape of a product cannot be monopolized.
A single color or the natural color of a product: an isolated color applied to a product cannot be registered, although distinctive combinations of colors may be eligible.
Signs That Cannot Be Registered as Trademarks
Article 3 of the Law includes additional cases in which, even if the sign has some degree of distinctiveness, its registration is prohibited:
Identical or confusingly similar marks: signs that could create a likelihood of confusion with trademarks previously applied for or registered for the same products or services.
Geographical indications or designations of origin: names of countries or regions linked to products whose characteristics are determined by their geographical environment.
Misleading marks: signs that may deceive consumers regarding the nature, quality, origin, composition, or price of the products or services.
Marks contrary to morality or public order: including offensive or obscene expressions, or those promoting unlawful activities.
Official names and symbols: such as flags, coats of arms, or names of provinces, municipalities, or recognized international organizations.
Names, pseudonyms, or portraits of individuals: these require express consent of the person concerned or their heirs up to the fourth degree.
Business designations: terms that directly describe a company’s activity. Example: “Compañía de Seguros“/ “Insurance Company” (although distinctive elements within such designations may be registrable).”
Non-distinctive advertising slogans: slogans must be original and not commonly used in commerce.
Other Non-Registrable Signs
Beyond the Trademark Law itself, there are specific prohibitions set forth in other legal provisions and international treaties:
Decree 206/2001: prohibits the registration of the terms biological, ecological, organic, ECO, or BIO for agricultural products (such as food, fibers, wood, furniture, or paper).
Decree 42.366/1934: prohibits private entities from using the word “National.”
Law 26,687: prohibits the registration of terms such as Light, Milds, Smooth, or Low in nicotine and tar content for tobacco products.
Paris Convention – Article 6 Ter: prohibits the registration of State emblems, official signs of control, and emblems of intergovernmental organizations without authorization. A recent example is the term “Patagonia”, which was recognized in 2022 as a State emblem of Argentina under Article 6 Ter of the Paris Convention, thereby preventing its registration as a private trademark.
