Registering a trademark in Argentina is a filing made before the INPI, structured in six steps. Here is what each one involves, where applications get stuck, and why an early mistake can cost you the mark altogether.
To register a trademark in Argentina you file an application with the National Institute of Industrial Property (INPI), select the correct class of goods or services, clear examination and the opposition period, and obtain the grant, which lasts ten years and is renewable. The procedure is entirely online and, where nobody opposes and no objections are raised, it can be resolved in a matter of months. The hard part is not filling in the form: it is getting the early decisions right, because a poorly conducted clearance search or a badly chosen class cannot be fixed later without starting over.
Key point: registering a trademark is a strategy, not a form. The clearance search and the choice of class are decided at the outset and shape everything that follows. That is where the do-it-yourself route tends to lose the mark, or the money, over a mistake that looked minor at the time.
Step 1: Clearance search (the step most often underestimated)
Before filing anything, you need to establish whether your mark is available. Searching for an identical name is not enough: both the INPI and the courts also refuse marks that are confusingly similar, meaning those resembling a registered mark visually, phonetically or conceptually. “Solántica” can collide with “Sol Atlántica”; “Kaffé” with “Café”. A superficial search returns a false “it’s free”, you file, you pay, and months later an opposition appears and stops you. This is the step where professional input prevents the most expensive mistake, because what has to be assessed is the likelihood of confusion, not merely a literal match.
Step 2: Choosing the right class (Nice Classification)
Trademarks are registered by class under the Nice Classification: 45 categories of goods and services. You register your mark for what you actually do, not “for everything”. Two classic mistakes are made here: claiming too little, leaving your core activity unprotected so that someone else can use your name in that class, or claiming too much and paying official fees for classes you do not need. Selling clothing and running a retail outlet are not the same class; it is worth analysing where the business sits today and where it is heading.
Step 3: Filing the application with the INPI
The application is filed online through the INPI’s e-filing portal, using your CUIT (the Argentine tax identification number) and Clave Fiscal (the tax authority’s access credential). You upload the sign (word mark, if it is just the name; composite, if it includes a logo), the class, the owner’s details, and pay the applicable official fee. From that moment you hold a priority date: if someone else turns up later with the same mark, you got there first. That is why it pays not to delay filing once the name has been settled.
One point specific to applicants based outside Argentina: under section 10 of the Annex to Decree 242/2019, an applicant whose actual domicile is abroad must, in addition to the electronic address for service, establish a special domicile in the City of Buenos Aires. In practice this means foreign applicants prosecute through local representation rather than filing directly.
Step 4: Examination and publication in the Trademark Bulletin
The INPI examines the mark for absolute grounds of refusal (that it is not deceptive, generic or contrary to law) and publishes it in the Trademark Bulletin. That publication is what allows third parties to become aware of the application and, if they consider it prejudicial, to oppose. It is an automatic step, but it starts the clock on the most sensitive deadline in the whole procedure. Descriptiveness is one of the grounds most frequently applied, as illustrated by the case in which OpenAI lost a mark for describing the product.
Step 5: The opposition period
Once the mark is published, a period runs during which the owner of any earlier mark may file an opposition. If your application is opposed, prosecution halts until the conflict is resolved: the opposition has to be answered in time, a coexistence agreement negotiated, or the matter litigated. This is a critical moment governed by non-extendable deadlines, and an opposition answered badly, or not answered at all, can cost you the mark. Together with the clearance search, this is where professional support changes the outcome. And if the problem runs the other way, with someone already using your mark, there are specific actions available to stop that use (in Spanish).
Step 6: Grant, term and renewal
Once everything is cleared, the INPI grants the registration. The mark lasts ten years and is renewable indefinitely for equal periods. But registration is not the finish line: if you do not use the mark, you can lose it. There is a cancellation mechanism for non-use (in Spanish) allowing a third party to have your registration extinguished if you have not exploited it. Registering and then forgetting about it wastes the investment: a mark has to be used, watched and renewed.
How long does it take and what does it cost?
Where nobody opposes and no objections are raised, the procedure can be resolved in a matter of months; with oppositions, it extends according to how long the conflict takes to settle. Cost has two components: the INPI’s official fees (charged per class and updated periodically) and professional fees. Filing alone purely to save the professional fees is the most fragile economy available: if the mark falls over a badly chosen class or a mishandled opposition, you lose the official fee, the priority date and, very often, the name itself.
Frequently asked questions
Can I file the application myself, without a lawyer? Legally yes, if you are based in Argentina: the procedure is online and no legal representation is required. But the decisions that determine whether your mark survives, namely assessing likelihood of confusion, selecting classes and responding to oppositions, are the ones that demand the most expertise. You can do it alone; the question is how much the mark you are risking is worth. Applicants domiciled abroad are in a different position, since they must establish a special domicile in Buenos Aires.
What is an industrial property agent? A professional admitted to the register kept by the INPI, authorised to prosecute trademarks and patents on behalf of others. At Herrera & Flamenco Abogados we are industrial property agents as well as lawyers: we combine specialised prosecution before the INPI with full legal capability to defend your mark should a conflict, an opposition or an infringement arise later on.
Does owning the .com.ar domain or the trade name registered with the tax authority already protect me? No. A domain name, a trade name and a registered trademark are three different things. Only registration with the INPI gives you the exclusive right over the sign and the ability to stop others from using it.
Is the mark valid throughout the country? Yes, registration is national in scope. To protect it in other countries you must register there or use the available international routes; an Argentine mark does not automatically cover you abroad.
Should I register the name or the logo as well? It depends on your strategy. A word mark (the name alone) gives the broadest protection over the word itself; a composite mark protects the combination of name and design. Combining both is often the better course.
