Champagne vs. Champanillo: A Success Story That Redefines the Protection of Designations of Origin

CONTEXT

A dispute that raised questions about the limits of protection for designations of origin

The Comité Interprofessionnel du Vin de Champagne (CIVC), the organization responsible for protecting the Champagne protected designation of origin (PDO), detected the use of the term “Champanillo” to identify a chain of tapas bars in Catalonia, as well as its use in domain names, social media, and promotional materials.

In the European Union, PDOs are subject to a specific protection regime at the Union level, as set forth in Regulation (EU) No. 1308/2013, which ensures their protection against misuse in all Member States.

The main legal challenge in this case stemmed from the fact that the products in question were not comparable to Champagne, but rather restaurant services, which raised a key question: Can there be an infringement of a PDO when the sign is used for services rather than products?

 

LEGAL PERSPECTIVE

Protection should extend to those uses that evoke an association in the consumer's mind

The argument in this case was based on a central idea: the protection of designations of origin is not limited to identical or similar products, but must extend to those uses that evoke a certain association in the consumer’s mind.

If the use of the “Champanillo” trademark led the average consumer to think directly of Champagne, protection should be granted, regardless of whether it was used to identify tapas bars rather than sparkling wines.

Furthermore, that association in the consumer’s mind also constituted an improper exploitation of the reputation associated with the Champagne designation of origin: the mark benefited from the prestige, recognition, and value built up by the PDO.

This approach required going beyond traditional analysis and relying on the European framework (EU Regulation 1308/2013). Consequently, the case led to a preliminary ruling requested by the Provincial Court of Barcelona before the Court of Justice of the European Union, which proved decisive in clarifying and defining the limits of protection for designations of origin.

 

CASE DEVELOPMENT

A decade of litigation leading up to the final decision

The process spanned nearly a decade and went through several stages before this shift in approach was finalized.

Following an initial unfavorable ruling at the trial court level, the Provincial Court of Barcelona referred the matter to the CJEU, shifting the focus of the debate from the similarity between products to the concept of evocation.

Until then, the Court of Justice had interpreted—in various decisions, including the judgments of June 7, 2018, in Case C-44/17, and December 17, 2020, in Case C-490/19—the concept of evocation of a PDO, but it had never specifically ruled on the question of whether the protection afforded by designations of origin extends not only to conduct related to products but also to services.

The CJEU’s response, in its September 9, 2021, judgment (Case C-783/19), was decisive. It confirmed that the protection of appellations of origin also extends to services, provided that the use of the sign creates a sufficiently direct link between the protected appellation and the consumer.

Based on that criterion, the Provincial Court reviewed the case and concluded that the use of “Champanillo” constituted an infringement by association. In reaching this conclusion, the court did not limit itself to a nominal analysis but rather assessed the totality of the circumstances: the clear phonetic and conceptual similarity between the signs, the inclusion of the term “champán” in the disputed sign, its use in contexts related to the consumption of beverages, and, in particular, the unfair exploitation of the reputation associated with Champagne.

  

RESULT

The Supreme Court reaffirms a legal principle that redefines the scope of protection for designations of origin

On April 8, 2026, the Supreme Court upheld in its entirety the ruling issued by the Provincial Court of Barcelona, applying the doctrine established by the Court of Justice of the European Union. This brought the proceedings to a close, thereby consolidating the approach that had been adopted.

In line with the CJEU’s interpretation, the ruling reaffirms that an infringement occurs when the PDO “Champagne” is invoked, even in the absence of identity or similarity between products, and that this protection also extends to services when the use of the sign creates a sufficiently direct association in the mind of the consumer. It also confirms that such uses may constitute an unfair exploitation of the reputation associated with the designation of origin.

In accordance with these principles, the Supreme Court upholds the order to cease use of the “Champanillo” trademark, remove related materials, and cancel the associated digital assets.

Beyond its specific effects, the ruling marks a milestone in the interpretation of the concept of “evocation” of PDOs under Spanish law. The Supreme Court expressly incorporates the CJEU’s criteria and integrates them into national judicial practice, thereby establishing a standard that broadens the scope of protection for designations of origin and strengthens their defense against indirect uses.

This ruling not only provides legal certainty but also sets a clear precedent for future cases by confirming that the protection of PDOs does not depend on the similarity between products, but rather on the sign’s ability to trigger an association with the protected designation in the consumer’s mind.

Legal Limits on the Reuse of Festival Posters: Copyright Infringement Due to Plagiarism

Organizing cultural and festive events often involves commissioning or using creative works, such as posters, illustrations, or graphic designs. These creations are protected by intellectual property laws, which require the author’s permission for their use.

A ruling handed down by a commercial court has reiterated that the substantial reproduction of a work without permission—even if formal variations are introduced—may constitute plagiarism and result in financial liability for the person who uses it.

Facts of the Case

The dispute arose after it was discovered that the promotional poster for the Don Benito (Badajoz) City Council’s Carnival had allegedly been plagiarized—or at least inspired by—the one designed by Torres Franquis for the same festivities, but nine years earlier (2016) and for the town of Santa Cruz de Tenerife, for which he was paid 1,630 euros.

The similarity concerned the main element of the design: a “chicharro” fish depicted in a distinctive graphic style that had become a visual symbol of the original event.

The poster used by the town in Extremadura retained that same central motif, changing only the colors, adding some decorative elements to the background, and substituting the typeface.

After sending several letters without receiving a response, the creator filed a lawsuit seeking:

  • recognition of the infringement of his copyrights
  • the removal and destruction of all copies, both in physical and online formats
  • compensation for the damages suffered

Criteria Applied by the Court

Minor changes do not rule out plagiarism

The judge ruled that the modifications made by the city council lacked sufficient creative substance to constitute a new work.

Despite these modifications, the essential features of the original design remained: the same dominant element, a matching graphic configuration, and a substantially identical structure. The similarity was therefore recognizable and relevant from a legal standpoint.

On that basis, the ruling finds that the use of the poster without the author’s authorization constitutes a copyright infringement under the Intellectual Property Law. Furthermore, it also finds that moral rights have been infringed, in particular the right to the integrity of the work and the right to be identified as the author.

Ownership of Rights

The Don Benito City Council argued that ownership of the rights belonged to the Santa Cruz de Tenerife City Council, since it was the entity that had commissioned the poster at the time. The judge rejected this argument and noted that the commission did not entail the acquisition of full ownership of the exploitation rights. Thus, the author remained the original owner of the rights, while the city council held only a right of use under the agreed terms, without the authority to freely dispose of the work.

Compensation and Measures Taken

The ruling set total compensation at 6,500 euros, distinguishing between two categories:

  • Financial damages: 500 euros, equivalent to the amount the author would reasonably have received had he authorized the use.
  • Compensatory damages: 000 euros, taking into account the public dissemination of the poster, its institutional use, and the creator's professional career.

In addition, it was agreed that:

  • the immediate cessation of use
  • the removal and destruction of physical copies
  • the removal of digital publications
  • the publication of the resolution in local and regional media
  • the imposition of court-ordered costs.

Practical Implications

This case highlights that the concept of “inspiration” has clear legal boundaries in the context of intellectual property. When a new creation reproduces the essential and recognizable elements of a prior work—even if it incorporates incidental or decorative changes—it cannot be considered independent.

Simply changing colors, fonts, or minor details does not alter this conclusion if the substantial identity of the design is preserved. In such cases, the use of the work without authorization constitutes unauthorized exploitation and, therefore, a copyright infringement.

The ruling under review confirms this approach by finding plagiarism despite the changes made and by recognizing both the financial and emotional harm resulting from the institutional use of the poster.

Proper management of intellectual property rights and respect for authorship are essential to preventing unauthorized use of creative works and the resulting financial and legal liabilities arising from their improper exploitation.

On-Call and Rapid Response Protocol for MWC 2026, Now Also Extended to Alimentaria and Hostelco

The hosting of major international trade shows such as the Mobile World Congress 2026 involves a high concentration of commercial launches, technological innovations, and new products, which significantly increases the risk of disputes regarding industrial property, intellectual property, and unfair competition. To ensure effective and prompt judicial protection during these events, the Commercial Courts have once again activated the On-Call and Rapid Response Protocol, which in 2026 will not only apply to the MWC but, for the first time, will also extend to the Alimentaria and Hostelco.

In this article, we analyze the scope of the Protocol at MWC 2026, its main new features, and its application to the Alimentaria and Hostelco trade shows, as well as the importance of adequate advance legal planning by participating companies.

The 2026 Mobile World Congress Protocol: Continuity and Consolidation

The Mobile World Congress 2026 will be held from March 2 to 5, 2026, and will once again bring together the leading companies in the technology and telecommunications sectors. As has been the case for more than a decade, the Commercial Courts of Barcelona, together with the Commercial Courts of Alicante (European Union Trademark Court), have agreed to activate a specific protocol for on-call duty and rapid response, applicable during the month leading up to the event and, particularly intensively, during the days of the congress.

The activation of this system will address potential conflicts between exhibiting companies and holders of industrial and intellectual property rights that may give rise to requests for preliminary proceedings or injunctive relief. The system’s objective is to facilitate expedited and priority processing of such proceedings, while ensuring the effectiveness of judicial protection during the event.

Measures Provided for in the Rapid Response Protocol

The Protocol establishes a series of specific commitments on the part of the judicial bodies, aimed at providing a prompt response to any disputes that may arise during the conference.

Expedited Processing of Proceedings and Precautionary Measures

The courts are committed to giving priority processing to:

  • Requests for preliminary proceedings and fact-finding proceedings.
  • Applications for urgent interim relief, with or without a hearing for the defendant.

These actions may relate, among other things, to alleged infringements of patents, trademarks, industrial designs, and intellectual property rights, as well as acts of unfair competition and unlawful advertising, provided that they are related to products or services being presented, exhibited, or promoted at the Mobile World Congress.

Shorter resolution times

The court settlement sets particularly short deadlines for resolution:

  • A maximum period of 48 hours to rule on preliminary proceedings and injunctive relief without a hearing for the defendant.
  • A maximum period of 10 days for ruling on preliminary injunctions with a hearing scheduled, provided that a preliminary brief has been filed.

Preventive Measures

The Protocol expressly provides for the possibility of companies filing preventive briefs when, in the face of a potential dispute, they have reasonable grounds to fear that they may be the subject of a motion for preliminary injunctive relief without a hearing. A decision on whether to accept these briefs is made within approximately 24 hours, allowing the court to become aware of the potential defendant’s position in advance.

Expanded Scope: Digital Environments and Artificial Intelligence

The scope of application of the Protocol expressly includes actions taken:

  • In virtual environments, online platforms, or the metaverse.
  • Through content generated by automated systems or artificial intelligence, such as images, text, videos, sounds, voices, or algorithmic decisions.

Extension of the Protocol to Alimentaria and Hostelco 2026

In a significant development for 2026, the Commercial Courts of Barcelona have agreed to extend the On-Call and Rapid Response Protocol—initially designed for the Mobile World Congress—to the Alimentaria and Hostelco 2026 trade shows, which will be held from March 23 to 26, 2026.

This extension will allow the same system of expedited processing and urgent resolution to be applied to disputes that may arise in connection with food products, beverages, restaurant and hospitality equipment, and matters related to trademarks, designs, trade secrets, intellectual property rights, and acts of unfair competition. The court agreement also places specific emphasis on protecting the confidentiality of sensitive information, in accordance with regulations on trade secrets.

The Importance of Prior Legal Preparation

Experience gained from previous editions of the Mobile World Congress shows that proper use of the Protocol requires advance legal preparation on the part of exhibiting companies. Identifying risks in advance, analyzing one’s own rights and those of third parties, and planning for potential legal proceedings are key to minimizing incidents during the event.

Having access to expert advice before the event begins puts companies in a better position both to respond quickly to a potential infringement and to avoid unexpected injunctive relief that could affect their business operations or launch strategy.

Elzaburu and the MWC Protocol: Proven Experience

At ELZABURU, we have played a significant role in the practical implementation of the on-call and rapid response protocols associated with the Mobile World Congress, having participated in approximately 32% of the cases handled within this framework over the past 8 years.

At the 2026 edition, and in conjunction with the Mobile World Congress, Alimentaria, and Hostelco, we will once again support our clients by implementing legal strategies tailored to this specific procedural framework, aimed at ensuring effective protection of their industrial and intellectual property rights and properly managing the risks associated with their participation in these events.

The Supreme Court Confirms That “dónut” and “Donuts®” Are Not the Same: Key Legal Points of the Ruling on Trademarks

The recent Supreme Court ruling confirming that “dónut” and “Donuts®” are not the same brings an end to a legal dispute that began in 2017 and sends a strong message to the market: the inclusion of a term in the dictionary does not, in and of itself, eliminate the legal protection of a registered trademark. This ruling, which is of enormous importance to business owners, executives, and legal counsel, clarifies the limits of descriptive use and strengthens the protection of well-known trademarks in Spain.

The High Court’s decision, issued by the Civil Division on October 28, 2025, held that a third party’s use of the term “Donut” was not a fair descriptive use and infringed upon the trademark rights of the Bimbo Group, owner of the well-known Donuts® trademark.

Source of the Dispute: Generic Use or Trademark Infringement?

Atlanta Restauración Temática used the term “Donut” on its website to describe donuts sold under its own brand, even though it did not hold any rights to that name. In the defendant’s view, this was merely a descriptive use of the term for a baked good.

However, Bakery Donuts (now Bimbo Donuts Iberia) considered that such use constituted an improper exploitation of the reputation of the Donuts® brand, a well-known trademark with more than 70 registrations with the Spanish Patent and Trademark Office (OEPM) that include that name.

Following an initial dismissal at the trial court level and the affirmation of that decision on appeal, the Supreme Court, in this recent ruling, reviewed the case on cassation and established legal precedent regarding well-known trademarks.

Dónut vs. Donuts®: Lexicalization Is Not Vulgarization

One of the central issues in the case was the inclusion of the term “dónut” (with an accent) in the Dictionary of the Royal Spanish Academy. The Supreme Court clarifies a key point:

  • The RAE expressly acknowledges the term's origin in the field of trademarks.
  • That inclusion constitutes lexicalization, but it does not imply a loss of distinctiveness or a dilution of the trademark.

The High Court makes a clear distinction between:

  • Lexicalization: the incorporation of a term into everyday language.
  • Loss of distinctiveness: a process resulting from widespread use that turns a trademark into a generic term, which has not occurred in this case.

Therefore, Donuts® remains a fully protected trademark, even though the term “doughnut” exists in everyday language.

The Limits of Descriptive Use Under the Trademark Law

Article 37 of the LM: The Requirement of Loyalty

The ruling is based on Article 37 of the Trademark Law, which permits the descriptive use of third-party marks only if it is done in accordance with fair industrial and commercial practices.

The Supreme Court concludes that, in this case, such good faith was not present, particularly because the trademark in question is a well-known one. Even seemingly descriptive use may be unlawful if:

  • It creates a mental association with the protected brand.
  • It dilutes the distinctive character.
  • It results in a loss of prestige.
  • It involves free-riding—that is, benefiting from the brand's appeal without contributing any value of one's own.

Relevant details considered by the Court

The Supreme Court highlights several factors that support the finding of a violation:

  • The use of the term “DONUT” in all capital letters, consistent with the registered form.
  • The absence of the accent and the lowercase letter (“dónut”), as noted by the RAE.
  • The existence of valid descriptive alternatives, such as “roscos,” “rosquillas,” or “berlinas,” which would have prevented the use of another party’s trademark.

Frequently Asked Questions About Litigation Involving Well-Known Trademarks

Can I use a word if it's in the dictionary?

Not necessarily. The fact that a term appears in the RAE does not authorize its unrestricted use in commercial transactions, especially if it coincides with a well-known registered trademark.

Is descriptive use always permissible?

No. Descriptive use must be fair and must not harm the legitimate interests of the trademark owner. For well-known trademarks, the standard is higher.

Does confusion have to exist for a violation to occur?

This is not the case with well-known trademarks. It is sufficient that the use evokes the trademark and results in an improper exploitation or a diminution of its value.

What are the possible consequences of such a violation?

Immediate cessation of the infringing use and, in certain cases, compensation. In this case, the Court does not award damages because the use was limited and has already been discontinued.

Did the Supreme Court analyze the concept of " secondary meaning " in this ruling?

No. The Supreme Court did not analyze the concept of “secondary meaning” nor did it base its decision on the acquisition of acquired distinctiveness. The legal analysis focused exclusively on the limits of descriptive use set forth in Article 37 of the Trademark Law and on the requirement that such use be fair, especially in the case of a well-known trademark.

A Key Precedent for Business Strategy

This ruling sets an important precedent in intellectual property law by making it clear that:

  • The presence of a trademark in everyday language does not automatically weaken its protection.
  • Companies should exercise extreme caution when using terms that match well-known trademarks, even for descriptive purposes.
  • Branding and marketing communication strategies should always be analyzed from a preventive legal perspective.

Copyright and Co-authorship in Artists' Studios: Practical Lessons from the Supreme Court Ruling

Today we spoke with Carlos Morán, a partner at Elzaburu who specializes in industrial and intellectual property litigation and unfair competition, about a recent Supreme Court ruling that has generated interest in the field of copyright and co-authorship in artists’ studios. Below, Carlos answers a series of questions that help clarify the practical scope of this ruling and the implications it may have for artists, collaborators, and professionals in the sector.

Context

The September 30, 2025, ruling by the Civil Chamber of the Supreme Court addresses, for virtually the first time, the issue of determining the authorship of works of art created in the context of an artist’s studio, but the reality is that the appeal had very little room for maneuver, and the Supreme Court essentially upheld the appellate ruling issued by Section 28 of the Provincial Court of Madrid on March 21, 2021. The case before the Supreme Court was already weighed down by the evidence presented at the trial court level and by the forcefulness of the appellate ruling. The Supreme Court adds little to it. The cassation ruling accepts as valid the facts found to be proven in light of the evidence presented and the legal rulings of the Provincial Court. The limitations inherent in the cassation appeal did the rest.

Supreme Court Criteria for Distinguishing Between Technical Assistance and Creative Contribution

Rather than legal principles, the Supreme Court has taken into account the facts that emerge from the evidence presented, namely:

  1. The plaintiff was an artist with proven professional qualifications.
  2. The salary he received for his work with the defendant was quite high.
  3. The plaintiff worked alone in the studio for many hours a day, and the defendant often traveled quite a bit
  4. Under these circumstances, it seems reasonable to assume that the plaintiff, when translating the defendant’s ideas into the painting, enjoyed creative freedom to express her own personality as well.

The Supreme Court’s ruling notes on several occasions that, according to the Provincial Court—whose assessment of the facts and evidence must be respected—the tasks performed by the plaintiff were “extremely important” and not merely “ancillary” or “complementary” to those of the defendant.

Employment Relationship and Recognition of Co-authorship: Potential Conflicts

The existence of an employment relationship between the parties, as established in a prior labor court ruling, was not taken into account by the Supreme Court due to a procedural issue: labor court rulings are not binding on civil courts. In a sense, the facts and evidence directly presented in the civil lawsuit take precedence over the precedents derived from the labor court ruling.

That said, it stands to reason that the existence of an employment relationship does not prejudge—for better or for worse—the facts of the case, which must be proven on a case-by-case basis. It is another matter entirely that the employment contract, as we will discuss later, may specify or emphasize certain conditions or characteristics that refute the notion that the tasks performed by the assistant or collaborator involve creativity.

The Significance of Working Alone in Determining Co-authorship

The fact that the co-author created the work on her own is yet another circumstance that demonstrates to the court— when considered in conjunction with all the other factors—that she imbued the works with her own personality or was in a position to do so. The ability to make choices is best exercised in solitude.

Obligations of the Lead Artist Following Recognition of Co-authorship

This is essentially a declaratory judgment (recognizing the plaintiff’s status as a co-author of the 221 works) that includes a single order of relief: the defendant must publish, at his own expense, an announcement in a nationally circulated art magazine stating that the plaintiff has been recognized as a co-author of the 221 works listed in the judgment.

Impact of the ruling on contemporary artists' studios: when working with collaborators or assistants

Artists’ studios have been a constant feature in the history of art and are not called into question by this legal precedent. The Supreme Court’s ruling, in fact, expressly addresses any misinterpretation of its decisions and any attempt to extrapolate or generalize its doctrine to the current situation of any artist’s studio. On this point, the ruling expressly states: it is not a matter of saying that any technical assistant in a studio can be considered the author of an artistic work in which they participated, but rather that “in this particular case,” the plaintiff, in the solitude of the studio, was capable of giving form to the defendant’s ideas by making her own decisions based on her personality.

That doesn't mean we can't learn from this situation:

  1. First, an artist who works in a studio setting with collaborators and assistants should take care to specify in the contract signed with them the circumstances that make it clear that the creative aspect—both in the conception and execution of the painting—belongs to the artist, that the collaborators’ contribution is purely technical, and that they have no freedom of choice or discretion in the creation of the work.
  2. Second, the artist must apply these contractual principles to the practice of his or her work in the studio, truly taking on the responsibilities that fall to him or her, beyond what is simply set forth on paper.
  3. Third, should the matter go to trial, one must not dismiss the evidence presented at the trial court level, nor fall into contradictions, nor adopt a high-handed attitude during cross-examination. It appears that the witness testimony and the cross-examination of the defendant may have played a decisive role in the case.

The Impact of Co-authorship on the Principal Artist's Intellectual Authorship

From a practical standpoint, it does not appear that the ruling will have any effects on the artist beyond the reputational aspect. All indications are that the paintings were commissioned and had already been sold, so their commercial exploitation has been virtually exhausted.

Otherwise, the artist has not lost his status as the author; it is simply that he must share that status with the plaintiff. In practice, this means only that if the artist wishes to refer to those 221 paintings, he would have to state (make it clear) that the plaintiff is a co-author.

Decisive evidence in establishing creative contribution

It appears, as we have already noted, that the witness testimony and the defendant’s cross-examination may have been decisive for the Provincial Court in determining how the plaintiff worked at the defendant’s workshop. These cross-examinations seem to have taken precedence over the expert opinion submitted by the defendant, the content of which is not sufficiently addressed in the judgment.

Could this ruling set a legal precedent relevant to the recognition of co-authorship in other similar artistic cases?

The ruling does not constitute“case law”in the strict sense, as it is practically the first of its kind. It is a ruling that relies largely on the CJEU’s doctrine regarding authorship/originality and cites a foreign precedent (the French ruling in the Renoir case). The Supreme Court itself also rules out a broad interpretation extending to other cases and emphasizes that its decision is based on the specific circumstances of this case.

However, the fact that the Supreme Court ruled in favor of the collaborator rather than the artist could lead to the mistaken belief that the floodgates have opened and that any“assistant”can follow the plaintiff’s example. It is necessary to guard against this kind of interpretation.

Legal Recommendations for Artists Who Work with Assistants

Given that the ruling should not cause anyone alarm, it is advisable for artists who work in a studio setting with collaborators to take this opportunity to review their contractual and factual situations to determine whether or not there is any risk to them arising from the ruling’s findings.

Anniversary of the Civil Procedure Act

Lawsuits in Spain: From Reform to Reform

Now that the implementation of the sweeping procedural reform under Organic Law 1/2025 has been completed—with the transformation, on December 31 of last year, of the courts of first instance into District Courts in nearly all judicial districts nationwide—it is worth looking back to recall that exactly 25 years ago today, another momentous reform took effect, one that introduced a new civil procedure. As everyone will recall, this was Law 1/2000 of January 7, on Civil Procedure. And how many parallels can be drawn between these two reforms!

Two Reforms Set to Transform the Justice System

Both were enacted at the start of the legislative year as Bill No. 1, while the holiday season was still underway; both were presented as the ultimate solution to judicial reform; both were given a one-year grace period to become fully effective; and both were the subject, in the days and weeks leading up to their implementation, of urgent calls for a moratorium from a wide variety of groups and social actors.

Twenty-five Years of Legislative Changes

But there is one fact—regarding the subsequent evolution of the Civil Procedure Act, whose twenty-fifth anniversary we are celebrating today—that we should not lose sight of when assessing the merits of this latest reform, with which we are beginning the new year. Although Law 1/2000 was once described as the definitive modernization of our country’s judicial system, its text has undergone no fewer than 35 legislative amendments since its enactment. The penultimate one, in fact, was introduced by Organic Law 1/2025.

Procedural Reforms and Recurring Expectations

The fact is that all procedural reforms claim to be the perfect “cure” for the endemic “ills” afflicting judicial proceedings—until they are replaced by a subsequent law that is based on that same “active ingredient.”

Trust in Legal Practitioners

In any case, let’s keep our fingers crossed and hope that the combined efforts of judges, court clerks, attorneys, and legal representatives will help overcome uncertainties and resistance for the benefit of those who find themselves needing to go to court to exercise their right to a fair trial.

Trademark Litigation: Legal Key Points, Examples, and Recommendations for Businesses

In an increasingly competitive and globalized market, brands not only identify products or services, but also embody reputation, trust, and commercial value. When disputes arise over the use of a brand, the outcome of litigation can directly impact a company’s viability and reputation.

In this article, we review what trademark disputes are, why they occur, some examples of real-life cases, and what steps can be taken to prevent them.

What are trademark disputes?

A trademark dispute is a judicial or administrative proceeding that arises when there is a conflict over the use, registration, or protection of a trademark. These proceedings may be brought before national, European, or international courts, depending on the scope of the dispute.

Generally, trademark disputes center on issues such as:

  • Infringement: unauthorized use of a trademark by a third party.
  • Invalidity: challenging a trademark registration on the grounds that it does not meet the legal requirements.
  • Expiration: loss of rights due to nonuse, public domain status, or other causes.
  • Unfair competition: the use of distinctive signs that cause confusion in the marketplace.

These lawsuits are significant for two reasons: first, they protect the trademark owner, and second, they help ensure a fair and transparent market for consumers.

Main Reasons for Trademark Disputes

Trademark disputes have various causes, although they tend to center on the following:

1. Similarity between distinctive signs

This is one of the most common reasons. When two trademarks share graphic, phonetic, or conceptual similarities, it can lead to consumer confusion.

2. Unauthorized use of a well-known or renowned trademark

Well-known trademarks enjoy enhanced protection. Unauthorized use by third parties, even in different industries, may lead to litigation.

3. Registrations in bad faith

There are cases in which a person or company registers a trademark with the intention of blocking or taking advantage of another party's reputation, leading to legal disputes.

4. International Conflicts

In a globalized world, many companies expand into new markets and encounter prior registrations or conflicting uses in other jurisdictions.

Examples of actual court rulings in trademark litigation cases

An analysis of case law provides insights into how courts interpret trademark rights. Below, we will summarize some representative cases:

The María Callas Case: Reputation Alone Is Not Enough Without a Connection to Specific Products

One example of a trademark dispute is the case involving the name of María Callas, the famous Greek soprano. The artist’s heirs attempted to block the registration of a figurative trademark with the EUIPO that included her name, for goods in Class 16 (stationery).

The opposition was based on three main arguments:

  • Ownership of an earlier word trademark registered in the European Union under the name “María Callas.”
  • Prior commercial use of the name in various markets.
  • The well-known reputation of the name "María Callas" in the EU, which, according to opponents, warranted enhanced protection.

However, the EUIPO Opposition Division rejected the claim for several compelling reasons:

  • No likelihood of confusion: The goods in question (stationery) were unrelated to the sectors in which prior use of the name had been established.
  • Insufficient evidence of reputation in Class 16: It was not demonstrated that the public associated the name “María Callas” with stationery, nor that such use was detrimental to the trademark.
  • Formal deficiencies in the opposition: some of the documentation was submitted in Greek without the corresponding English translation, which weakened the claim.

This case is a clear example of how the fame of a person or a distinctive sign is not, on its own, sufficient to block registrations for all classes of goods or services. To succeed in an opposition proceeding, it is essential to demonstrate a genuine and specific connection between the trademark and the goods or services in question, as well as an actual likelihood of confusion or unfair advantage.

The Choco Flakes Case: Trademark Infringement and Unfair Competition in the Food Industry

Another example in the area of trademark litigation is the dispute between Cuétara and Gullón over the use of similar packaging in the marketing of cookies.

In this case, Cuétara sued Gullón for unfair competition, arguing that the marketing of the “Choco Cereales” cookies improperly imitated both the figurative trademark “Choco Flakes” and the packaging Cuétara used to distinguish its products. These trademarks were duly registered with the OEPM and the EUIPO.

The case reached the Provincial Court of Alicante, which acts as the European Union Trademark Court. The ruling confirmed the infringement of Cuétara’s rights and established several key points:

  • Proven reputation: The court recognized that Cuétara’s trademarks were well-known in the cookie and cereal industry, which strengthens the level of protection against third parties.
  • Similarity of the packaging: Both featured an identical product (cookies dipped in milk in a bowl), accompanied by children's characters in a similar style—elements that created a similar perception among consumers.
  • Association among the relevant public: Despite certain graphical differences, the court found that the public would associate Gullón’s trademarks with those of Cuétara, given the visual and conceptual similarity of the packaging.
  • Unfair exploitation: The ruling concluded that Gullón was benefiting from the prestige and reputation of Cuétara’s trademarks, constituting a clear case of trademark parasitism.

Consequently, the ruling determined that:

  • The use of the Choco Cereales packaging infringed both the Spanish trademarks and the European Union trademarks owned by Cuétara.
  • Gullón was required to remove the non-compliant packaging from the market and destroy it, as well as to refrain from using it again.

This case is a good example of how the courts protect not only the trademark itself, but also the combination of graphic and commercial elements that could mislead consumers, especially in mass-market sectors such as the food industry.

Preventive Recommendations to Avoid Trademark Disputes

Although legal action is an essential tool for defending trademark rights, it is best to minimize risks before a dispute arises. Some key recommendations are:

  1. Pre-registration searches: Before applying for a trademark, it is advisable to conduct thorough searches to avoid conflicts with existing registrations.
  2. Global Protection Strategy: Companies with international operations should develop a trademark registration plan tailored to their target markets.
  3. Active trademark monitoring: There are monitoring services that alert you to applications for similar trademarks, allowing you to respond in a timely manner.
  4. Proper Contract Management: Clearly define ownership and use of trademarks in franchise, distribution, licensing, or joint venture agreements.
  5. Effective use of the trademark: Maintain actual and documented use to avoid cancellation proceedings due to nonuse.

The Importance of Specialized Advice

Trademark litigation highlights the strategic value of distinctive marks and the need to proactively protect them. Preventing disputes through an effective trademark strategy and, if necessary, defending one’s rights in court are essential for any company that wants to safeguard its competitiveness.

The Fight Against Piracy in CrossFit: Brand Protection in Sports

Over the past decade, CrossFit has evolved from a trend in the field of functional training into a global discipline with millions of followers and more than 12,000 affiliated gyms worldwide. This expansion has been accompanied by a parallel phenomenon: an increase in piracy and counterfeiting in the sport, particularly the misuse of registered trademarks such as“CrossFit.” This situation affects both rights holders and consumers, who may be misled into receiving a service that does not meet the quality standards associated with the brand.

Piracy in CrossFit: A Growing Problem

CrossFit is not only synonymous with a high-intensity functional training method; it is also a registered trademark. This distinction is essential to understanding the legal issues surrounding its use. While the training system (based on exercises such as burpees, snatches, or AMRAPs) can be freely practiced by anyone or any gym, the use of the name “CrossFit” is legally protected. In other words, a facility can offer similar workouts without legal issues, but it cannot use the CrossFit trademark without the appropriate license.

The unauthorized use of the name “CrossFit” by unaffiliated gyms constitutes a clear form of sports piracy. These facilities take advantage of the brand’s reputation and prestige to attract customers, without meeting the certification and training requirements or paying the licensing fees required by the brand. This practice not only infringes on intellectual property rights but also constitutes unfair competition against facilities that do operate within the established legal framework, investing in training and quality standards.

Sports Piracy: How CrossFit Defends Its Brand Legally

CrossFit Inc. has taken an active, global stance in defending its brand. The company has implemented a monitoring network that combines technology with the collaboration of its affiliate community. Through a reporting form available on its official website, anyone can report misuse of the brand. This network makes it possible to detect cases of CrossFit piracy at various levels, from large chains to small neighborhood gyms.

What is CrossFit's policy regarding trademark infringement?

The procedure begins with a friendly notice requesting that the infringer cease the unauthorized use of the trademark on items such as social media, whiteboards, signage, or T-shirts. If a satisfactory response is not received, the case is referred to the legal team in the relevant country. In Spain, this role is carried out by the law firm Elzaburu, which has represented CrossFit Inc. since 2015.

Over the past 10 years, 15 legal proceedings have been filed in Spain, 6 of which have resulted in convictions. Currently, there are eight active lawsuits pending in various national courts, although a significant portion of these disputes are resolved before they go to trial.

The amount of the claims has reached as high as 30,000 euros, a figure that may seem modest but reflects the fact that, in most cases, these claims are settled before the litigation becomes complicated.

Counterfeiting in Sports and Its Impact on the Market

The phenomenon of counterfeiting in sports is not new, but in rapidly growing disciplines such as CrossFit, it takes on a unique dimension. The professional appearance of many illegal facilities, the use of similar terminology, and the proliferation of social media as promotional channels make it difficult to distinguish between official and unauthorized operations. Added to this is the creation of disguised names such as “XtremFit,” “CrossBattle,” or “GarageWarriors.”

This practice is a clear example of unfair competition, as it creates confusion among consumers and undermines the efforts of those who comply with the regulations. Furthermore, piracy in CrossFit erodes the brand’s value, which has been built up over years of investing in its reputation and offering a unique athletic experience.

CrossFit’s legal strategy seeks not only to preserve the rights arising from its trademark registration but also to protect a business model based on certified training, standardized quality, and consumer trust. In this context, piracy in CrossFit represents not only a trademark infringement but also a structural risk that affects the identity and sustainability of the ecosystem built around this discipline.

The protection of industrial property rights in the sports sector is crucial to preserving market integrity and protecting both rights holders and consumers. At Elzaburu, we continue to work to ensure that trademark owners can effectively exercise their rights, promoting an environment of fair competition and respect for the law.

MASC: What Changes with the Entry into Force of Organic Law 1/2025

No, this isn’t a science fiction movie. On April 3, Organic Law 1/2025 of January 7 on the efficiency of the public justice system came into effect with regard to the new Alternative Dispute Resolution Mechanisms (MASC). This means that, from now on, it will no longer be possible to file a civil lawsuit without first attempting to resolve the dispute through one of the alternative methods proposed by the law.

Over the past three months, the term “admissibility requirement”—so characteristic of procedural law—has become widely known. By granting the MASC this status, the legislature has elevated “the temple of Concord” above “the temple of Justice.”

We said that this isn’t a movie, but the reality is that it could very well be a “remake.” The civil justice system already had this mechanism in place—through the judicial settlement procedure—until the 1984 reform, which transformed it into an optional process. And, by the way, to widespread applause.

The Impact on Industrial and Intellectual Property Litigation

There are quite a few new uncertainties emerging now regarding industrial and intellectual property litigation, which our litigation attorneys will be discussing over the coming weeks:

  • Are we facing one of those changes that are made so that everything remains the same—meaning that, in practice, commonprocedures such as the prior notice will continue to be used, with the necessaryupdates ?
  • Will the courts interpret these MASC as irremediable defects?
  • How will professional firms address MASCs and the new services they entail?

Let's hope, in any case, that *The Day of the MASC*—even though it isn't the title of a movie and despite its air of being a remake—doesn't end up becoming a piece of experimental cinema that leaves moviegoers bewildered.

Mobile World Congress 2025: Preparations and Protective Measures Regarding Industrial and Intellectual Property for Exhibitors

The annual Mobile World Congress, the world's largest mobile phone and technology trade show, is fast approaching. As usual, the event will take place at the Fira de Barcelona exhibition center over four days, beginning this year on Monday, March 3, and concluding on Thursday, March 6.

Risks to exhibitors arising from disputes over patents, trademarks, designs, or copyrights

Given that more than 2,000 leading companies in the sector participate in this conference, showcasing new telecommunications products, mobile applications, and software innovations to the world, the Mobile World Congress becomes, year after year, a setting prone to potential conflicts between companies, primarily due to possible violations of industrial and intellectual property rights.

There are three main risks faced by exhibitors:

1. Requests for injunctions against exhibiting companies.

In past editions of the MWC, the courts in Barcelona and Alicante have processed a large number of requests for ex parte injunctions within 48 hours and without prior notice to exhibitors. In some cases, the defendant companies were able to have the injunctions lifted by posting a substitute bond. In other cases, the exhibitors’ failure to respond or to post such a bond resulted in the injunctions remaining in effect for the duration of the conference.

2. On-site fact-finding procedures during the Congress.

In addition to preliminary injunctions, the courts have also processed, during some editions of the MWC, a number of requests for fact-finding proceedings aimed at obtaining information—at the event itself—about exhibiting companies, their products, and technical data.

3. Judicial presence at exhibitors' booths.

The risk posed by precautionary measures and fact-finding proceedings is even greater when we consider that, in previous editions, notification of the court ruling and its enforcement—through a demand to remove the displayed products—took place once the Congress had begun, through the presence—albeit discreet—of judges and law enforcement officials at the exhibitors’ booths.

Therefore, it is essential that exhibitors develop a strategy in advance to enforce their patent, trademark, design, or copyright rights and avoid incidents.

On-Call and Rapid Response Protocol: A Set of Precautionary Measures to Protect Industrial and Intellectual Property Rights

In light of these disputes, for years now, the Commercial Court of Barcelona—as well as the EU Trademark Court in Alicante—have implemented an On-Call and Rapid Response Protocol. This protocol serves the dual purpose of avoiding, to the extent possible, the adoption of preliminary injunctions without a hearing for the defendant and, at the same time, implementing effective measures to protect those rights.

Under this Protocol, the courts undertake to rule on the admissibility of requests for preliminary orders (intended to prevent the adoption of interim measures without a hearing of the defendant) on the same day they are filed (within 24 hours). In addition, they undertake to rule on requests for precautionary measures within 2 days (48 hours), scheduling a hearing within 10 days if a preventive brief has been filed.

The Protocol will take effect on February 1 and will remain in effect until the last day of the conference, March 6.

Therefore, now is the time for companies participating in the Mobile World Congress to plan ahead and take the necessary steps to ensure the protection of their rights, thereby avoiding potential setbacks during the event.

At ELZABURU, we have played a significant role, participating in approximately 25% of the cases resolved by the courts under the Mobile World Congress Protocol over the past 7 years. This year, the firm will once again provide support to its clients by implementing measures both to effectively safeguard their industrial and intellectual property rights and to mitigate any risk of unexpected actions by third parties that could jeopardize their normal participation in the upcoming congress.
