Trademark law operates as a contest of perception, geography, and legal precedent rather than a binary application of right versus wrong. The protracted friction between the Irish fast-food chain Supermac’s and McDonald’s illustrates this complexity. Recent decisions in the European Union and the United Kingdom reveal conflicting outcomes for identical marks, offering critical insights for multinational entities navigating brand protection.
The European Ruling: Confusion and Conceptual Similarity
In June 2026, the Fifth Board of Appeal of the European Union Intellectual Property Office (EUIPO) refused to register the EU word mark SUPERMAC’S for restaurant services. The decision cited a likelihood of confusion with McDonald’s BIG MAC trademark.
The EUIPO analysis focused on consumer deconstruction of words. The board determined that English- and German-speaking audiences mentally split "SUPERMAC’S" into "SUPER" and "MAC." In this framework, both "SUPER" and "BIG" were viewed as laudatory descriptors with low distinctiveness. The element "MAC," however, retained its distinctive role in both signs.
Consequently, the board found visual and auditory similarity at a below-average degree, but conceptual similarity at least to an average degree. BIG MAC was recognized as having acquired enhanced distinctive character through intensive use across the EU. Because meat sandwiches (Class 30) and restaurant services (Class 43 are related in the consumer’s mind, the board reasoned that the combination of sign similarity and BIG MAC’s strong reputation created a likelihood of confusion. Consumers could reasonably perceive SUPERMAC’S as a sub-brand or variant of BIG MAC.
Supermac’s argued for relevance based on decades of coexistence in Ireland without actual confusion. The EUIPO rejected this, noting that peaceful coexistence in a single member state does not guarantee harmony across the entire European Union. Supermac’s faced the prospect of further appeal to the General Court of the European Union.
The British Counter-Narrative: Association Is Not Confusion
In contrast, the United Kingdom Intellectual Property Office (UKIPO) dismissed McDonald’s opposition in July 2026, allowing Supermac’s to register both its word and figurative marks for SUPERMAC’S in the UK.
The divergence stemmed from how the UKIPO weighed the "MAC" element. While accepting that BIG MAC possessed a high degree of distinctive character in the UK, the hearing officer found only low or very low visual similarity between SUPERMAC’S and marks such as McDONALD’S and MCAFE. Even when comparing SUPERMAC’S to BIG MAC, the differences were deemed sufficient to distinguish the two in the mind of the average consumer.
McDonald’s attempted to invoke a "family of marks" argument, suggesting that its extensive use of prefixes like "Mc-" and suffixes like "-MAC" created a recognizable commercial family. The UKIPO refused this, noting that neither group contained enough qualifying marks to establish such a broad connection.
The pivotal distinction lay in the assessment of consumer perception. The UKIPO concluded that while SUPERMAC’S might evoke an association with BIG MAC due to the shared syllable, this did not equate to confusion regarding commercial origin. In the UK legal framework, association is not infringement, only confusion constitutes it. McDonald’s claims based on reputation and passing off failed, clearing the path for Supermac’s registration within British borders.
Strategic Implications for Global Businesses
This split decision underscores that territoriality remains fundamental in intellectual property strategy. A brand that appears identical on paper can trigger entirely different legal reactions depending on local jurisprudence and consumer psychology.
For businesses operating internationally, this case highlights three critical lessons regarding trademark confusability and monitoring:
1. The Nuance of "Likelihood of Confusion"
Legal offices do not apply a monolithic standard for confusion. The EUIPO focused heavily on conceptual similarity and the enhanced distinctiveness of the opposing mark, allowing reputation to tip the scale toward refusal. The UKIPO maintained a stricter boundary between association and confusion, requiring a higher threshold of visual and auditory overlap to prevent registration. Multinational companies cannot assume that a successful defense in one jurisdiction guarantees success in another.
2. The Limits of "Family of Marks" Strategies
McDonald’s relied on its vast portfolio of "Mc-" and "-MAC" branded products to argue for a protective umbrella. The UKIPO’s rejection of this theory indicates that establishing a "family of marks" is difficult. If the office determines that the common element does not dominate the overall commercial impression, or if the portfolio is not cohesive enough, the shield of brand family protection may fail.
3. The Imperative of Active Monitoring
The protracted nature of this dispute illustrates why trademark monitoring cannot be passive. McDonald’s opposed the application in both regions, recognizing the potential dilution of its iconic BIG MAC mark. However, the different outcomes demonstrate that even vigilant monitoring and opposition do not guarantee uniform protection. Businesses must anticipate that legal standards for brand identity vary by region. A strategy that works in Brussels may not hold up in London, and vice versa.
Conclusion
The coexistence of Supermac’s and McDonald’s remains a complex dynamic, legally more stable in the UK than in the broader EU. This case reinforces that trademark law is not merely about ownership of a logo or name, it is about managing perception across fragmented legal landscapes.
As brands expand globally, they must recognize that brand protection is not a single shield but a series of localized defenses. Understanding how different jurisdictions weigh the balance between recognition and confusion is essential for preserving brand integrity in an increasingly interconnected market.
