A family of trademarks is a key strategic resource for companies seeking to consolidate their presence in the market.

The concept covers a set of related trademarks that share a common element, such as a name, design, or concept, and that work in synergy to strengthen the corporate identity. Below we explore what a family of trademarks is, the possible associations, the steps to register it, and successful examples.
What is a family of trademarks?
In intellectual property, a family of trademarks is a group of marks connected by a distinctive element. This can be a name, a slogan, or a specific theme that identifies them as part of the same commercial strategy. They are trademark registrations held under the same ownership that operate together to boost the company’s presence.
Their defining feature is an approach that strengthens a company’s identity by linking products or services under a consistent image, building recognition and trust among consumers. In addition, a family of trademarks makes legal protection easier against misuse or similar registrations by third parties, providing a solid strategy in competitive markets.
In Argentina, the protection of trademarks, including families of trademarks, is governed by Trademark Law No. 22,362, which sets out the requirements and procedures for registering and enforcing trademark rights.
The best-known example in our country is “Mercado Libre.” It shows how a company can register several marks, such as “Mercado Pago” and “Mercado Envíos,” achieving consistency and immediate recognition among consumers.
Distinctive features
The associations within a family of trademarks vary according to business objectives and the target market. The most common components include:
- Linguistic elements: the use of key words or common prefixes or suffixes.
- Visual designs: for example, consistent colors, logos, or graphic styles.
- Common themes: concepts aligned with the products or services offered.
These associations allow consumers to quickly identify the marks as part of a group, reinforcing their trust and loyalty.
How do you register a family of trademarks?
Registering a family of trademarks requires planning and strategy. In our view, the essential steps are:
- Initial analysis: identify the common element that will connect the marks.
- Trademark search: verify that the proposed names, logos, or designs are not in use or registered by third parties.
- Filing the applications: register each mark individually with the INPI (Argentina’s National Institute of Industrial Property) or with the equivalent agencies in other countries.
- International protection: consider registering in key markets to avoid legal conflicts.
We always recommend working with a team specialized in intellectual property: it ensures a successful registration without setbacks.
Success story: Mercado Libre
Mercado Libre is an outstanding example of a family of trademarks. Its main brand has expanded with complementary services such as Mercado Pago, Mercado Envíos, and Mercado Crédito. Each of these marks reinforces the perception of the group’s reliability and strength.
In conclusion, a family of trademarks is a powerful tool for diversifying and consolidating a company’s position in the market. By sharing a common element, these marks achieve immediate recognition and increase consumer trust. At Eguía, we can advise you on protecting and getting the most out of your intangible assets.
