The moment of ambush marketing to evade the official sponsor

The start of the Madrid Open highlights one of the most tempting – and delicate – strategies of contemporary marketing: leveraging the wave of a major event without paying the cost of official sponsorship. The proximity of other major international events, such as the FIFA World Cup or the tours of artists and bands that gather crowds in closed spaces, is a significant draw. Rosalía's Lux Tour 26 in Madrid attracted 70,000 live viewers; the FIFA World Cup final was followed by 1.420 billion people, according to FIFA figures.

This situation closely resembles the famous photograph of the 36 young Dutch women who were expelled during the World Cup in South Africa for wearing orange clothing as part of a campaign linked to the brewery Bavaria when the sponsor was Budweiser: a classic example of guerrilla marketing by association. The lesson still holds: when creativity becomes a resource to make people believe that a brand is part of the official ecosystem of the event, the risk skyrockets.

The practice is well known: a brand attempts to capitalize on the social impact, emotional context, and media attention generated by a sporting competition, festival, or cultural event to gain more visibility. Problems arise when this proximity ceases to be contextual and begins to suggest an unofficial relationship that does not exist. This is where the red line described by experts in trademark and intellectual property law is crossed.

As Pilar Sánchez-Bleda, managing partner of Media & Tech at Auren Legal, points out, guerrilla marketing "was born with a very clear philosophy: to associate a brand with a mass event without being an official sponsor, exploiting this unauthorized association to create confusion among the public and benefit from it".

Legal professionals mark the line that should not be crossed. Patricia Revuelta, partner in intellectual property at Ecija, summarizes the criteria clearly: "Spanish law does not prohibit, in abstract, a brand referring to a major event. What is prohibited is unfair advantage, not the simple exploitation of the context." The key, she adds, lies in the impression received by the relevant public: "The limit is crossed when the public might think that the brand in question is, in fact, an official sponsor".

Cristina Duch, partner specializing in intellectual, industrial, and technological property at Pérez-Llorca España, places the threshold at the "undue association" with the event or its official sponsors. As she explains, infringement can occur due to a likelihood of confusion or through the exploitation of another's reputation, even if there is no express statement of sponsorship. In other words: it is not necessary to say "we are sponsors" to have problems; it is enough to create a sufficiently suggestive appearance.

The first prohibited area is evident: the use of distinctive signs, official names, emblems, trophies, mascots, slogans, or any protected element of the event or its sponsors. It is also prohibited to use phrases such as "official sponsor", "partner" or other expressions reserved for those who have paid for that right. The second grey area, more subtle, refers to false appearances: campaigns that do not literally copy anything but create a mental association that is too close.

In Spain, the legal response mainly arises from unfair competition and trademark protection; there is no separate classification of ambush marketing as an infringement in itself. However, in other countries, the regulations are much stricter. Pablo Hooper, partner specializing in intellectual property and sports at Pérez-Llorca Mexico, explains how Mexico has strengthened its legislation to turn this conduct into a specific administrative infringement, with penalties and possible compensation.

New legal category

Hooper notes that this new provision penalizes anyone who "causes or induces the public to confusion, error, or deception, making them believe or assume, without justification, the existence of an official sponsorship relationship." With this model, the debate over confusion or parasitism is raised and intensified, and the brand that crosses the line of legality faces a much quicker and more robust response. Taking risks in Madrid is not the same as doing so in a country where the law already expressly punishes the mere undue association.

Spanish courts do not usually resolve these cases by applying mechanical rules, but through a thorough analysis of each campaign on a case-by-case basis. Revuelta speaks of a "trifocal" approach – material, intentional, and effective – to distinguish legitimate creativity from unfair exploitation. Duch, for her part, emphasizes that the analysis focuses primarily on the material element: the use of signs, symbols, expressions, visual or auditory codes that clearly evoke the event or its protected registered trademarks.

This examination encompasses the message as a whole, not just an isolated element. The text is important, but so are the image, sound, timing, and distribution channel. A campaign can be ingenious, even opportunistic, and remain legal if it does not lead people to believe there is a commercial link with the organizer or its partners.

Practical advice, according to experts, is clear: avoid any direct or indirect reference that suggests sponsorship, collaboration, or an official link. It is also advisable not to use hashtags, visual codes, or captions that are part of the protected brand universe of the event and to review each campaign as a whole before launching it. Revuelta adds that, in Spain, the best strategy is to work with messages "aligned with universal values such as effort, sportsmanship, overcoming challenges, speed, and talent" instead of using symbols reserved for the event.
