A business may use the same words on its storefront, products and website. Under Argentine law, however, those uses involve separate assets, and protecting one does not automatically secure the others.
A trademark, a trade name and a .com.ar domain are not the same thing in Argentina. A trademark distinguishes goods or services, and exclusive ownership is obtained through registration with the National Institute of Industrial Property (INPI). A trade name—called a designación under Argentine law—identifies a business activity and is acquired through use within a particular line of business. A domain name is the digital address used to reach a website. A business can control one of these assets while another person holds rights or practical control over another.
Key point: incorporating a company, opening social media accounts or registering a domain does not make you the owner of the trademark. Registering the trademark does not automatically reserve the company name or the matching domain either.
A trademark identifies the goods or services you offer
A trademark is the sign customers use to distinguish your goods or services from those offered by others. It may consist of words, a logo, a combination of both or another sign capable of identifying commercial origin. The Argentine trademark office describes this distinguishing function as central to the value and reputation built around a business.
Article 4 of Argentine Trademark and Trade Name Law 22,362 contains the decisive rule: ownership and exclusive use of a trademark are obtained through registration. Longstanding use may provide evidence and become relevant in a dispute, but it is not equivalent to holding a trademark registration and does not provide the same legal position.
Registration does not protect a name in the abstract for every possible activity. The application must identify the goods or services covered. This is why clearance searches and the correct selection of Nice classes for an Argentine trademark matter before filing. Our guide to registering a trademark in Argentina explains the filing process and the mistakes that commonly lead to objections, oppositions or protection that is too narrow for the actual business.
A trade name identifies the business activity
What is commonly called a trade name is regulated by Law 22,362 as a designación. It is the name or sign used to identify an activity, whether or not that activity is conducted for profit. It can be the public-facing name of a store, professional practice, technology venture or service business.
The legal logic is different from trademark registration. Articles 27 and 28 provide that rights in a trade name arise through use and only in connection with the line of business in which it is used. The name must also be distinguishable from earlier trade names in that field. Article 30 states that the right ends when the identified activity ceases.
This is why similar trade names may sometimes coexist in unrelated markets and why the scope of protection depends on evidence: when use began, where and how the name was used, the activity it identified and how the public encountered it. Unlike a registered trademark, there is no single nationwide certificate that resolves all of those factual questions by itself.
The trade name and the legal company name may also differ
The legal company name identifies the legal entity. It is the name under which a company signs contracts, holds bank accounts, issues invoices and appears in the relevant corporate registry. It may match the customer-facing trade name, but it does not have to.
For example, a company could be incorporated as “Servicios Gastronómicos del Centro SRL” while operating a café under a shorter brand. Registering the corporate name identifies the company as a legal person, but it does not automatically grant trademark exclusivity over the sign shown to customers. If that sign will carry the reputation of the business, trademark clearance and registration should be addressed separately.
A .com.ar domain is a digital address
A domain name allows customers to find a website. Domains under .ar are managed through NIC Argentina. Registration assigns the use of that internet address within the domain name system. It does not turn the domain into a trademark or prove that the registrant is entitled to use the same wording for particular goods or services.
This distinction has practical consequences. A domain may appear to be available even though an earlier trademark creates a conflict. The reverse can also happen: a company may secure the trademark while another person already controls the matching domain. Technical availability and the legal right to use a sign are separate questions.
Before adopting a business name, both sides should therefore be checked. NIC Argentina provides a domain registration procedure and a process for domain name disputes. A dispute may involve bad faith, legitimate interests, earlier use, registered trademarks and the parties’ conduct. It is not necessarily resolved by asking only who registered first.
An example: one identity, three different holders
Suppose Lucía opens a design shop under the name “Luna Taller.” She incorporates a company under a different legal name, hires an agency to build the website and begins selling products under LUNA TALLER. The agency registers the domain in its own account. Months later, Lucía discovers that a third party has applied for a similar trademark covering the same type of products.
The business is using a trade name, the company has a legal name and the website operates through a domain, but trademark ownership has not been secured. The domain is also under the formal control of a service provider. If the agency relationship ends, Lucía may face two simultaneous problems: recovering control of the digital address and defending the sign customers associate with her products.
The risk could have been reduced at the outset. The domain should have been registered in Lucía’s or the company’s name, with the agency acting only as a technical provider. The proposed trademark should also have been cleared and filed before substantial spending on signs, packaging and advertising.
What to align before launching in Argentina
1. Decide who will own each asset. The owner may be an individual or the operating company, but the decision should match the commercial structure and source of investment. If assets will have different owners, licences, permissions or transfer obligations should be documented.
2. Run coordinated searches. Review filed and registered trademarks, known trade names in the relevant field, proposed company names and domain availability. An available result on one database is not a full legal clearance.
3. Register the domain in the real owner’s account. A designer, developer or agency may manage technical settings, but should not become the unintended owner of an address that carries website traffic, email and business reputation.
4. File the trademark with the right scope. A logo-only filing may be insufficient when the words are the main asset. One class may also be inadequate when the project offers several types of goods and services. The filing strategy should reflect the actual business model.
5. Clarify rights in contracts. Agreements with founders, developers, designers and marketing agencies should state who owns trademarks, domains, social media accounts, designs and content, as well as how credentials and assets must be returned when the relationship ends.
6. Maintain and monitor the portfolio. Trademark registrations have use requirements and renewal deadlines; domains require renewal and accurate account information; trade name rights depend on actual use. Monitoring third-party applications can reveal a conflict while there is still time to respond.
Must all three names be exactly identical?
Not necessarily. A legal company name may need formal elements, the best available domain may require a short variation, and the registered trademark may include a logo. The important point is that customers can connect the assets without confusion and that the legal structure clearly identifies who controls each one.
If the exact domain is unavailable, do not select a variation that infringes someone else’s trademark. If the company has already been incorporated, do not assume that its name is protected for marketing purposes. If you acquire an existing business or trademark, verify that the transaction expressly includes domains, credentials and other digital assets. International owners should also remember that trademark rights are territorial: ownership elsewhere does not automatically replace an Argentine filing.
Frequently asked questions
Does incorporating a company protect its name as a trademark? No. The company name identifies the legal entity. Trademark exclusivity over the sign used for goods or services requires a separate filing and registration with INPI.
Does owning the .com.ar domain let me stop someone from registering the trademark? Not automatically. The domain may be relevant evidence, but trademark priority, coverage, earlier rights and legitimate interest are assessed under separate rules.
Can I register the trade name I already use as a trademark? Potentially, yes, if the sign is registrable, does not infringe earlier rights and is filed for the appropriate goods or services. A clearance search should come first.
What if the web agency registered the domain in its own name? Preserve the contract, invoices, communications and proof of use. A voluntary transfer may be the first option; if that fails, the NIC Argentina dispute procedure and other legal claims should be evaluated based on the evidence.
