In 2017, a regional Irish fast-food chain with fewer than 100 outlets did something that few businesses, large or small, had ever managed: it successfully cancelled one of the world’s most powerful fast-food companies’ trademark rights in the European Union.
The chain was Supermac’s. The giant was McDonald’s. And the trademark at the center of the battle was “Big Mac.”
This case study is not just a legal curiosity. It is a masterclass in how aggressive intellectual property tactics can backfire, how small businesses can weaponize trademark law in their own defense, and what every business owner, regardless of size, should understand about protecting and challenging trademarks.
Who Is Supermac’s?
Founded in 1978 by Pat McDonagh in Ballinasloe, County Galway, Supermac’s is an Irish fast-food chain known for its burgers, chicken, and breakfast offerings. For over four decades, it has been a beloved national brand in Ireland, a homegrown alternative to the American giants that dominate global fast food.
Despite its loyal following and steady growth, Supermac’s remained largely confined to Ireland. By the mid-2010s, McDonagh and his team were eyeing expansion into the broader European market. What they did not anticipate was that their first major obstacle would not be competition, real estate, or logistics. It would be a legal letter from McDonald’s.
Trademark Bullying in Action
When Supermac’s filed to register its brand name as an EU trademark in preparation for European expansion, McDonald’s objected. The American fast-food corporation claimed that the name “Supermac’s” was too similar to its “Big Mac” trademark, and that consumer confusion was likely.
This was not an isolated tactic. McDonald’s had a well-documented history of opposing trademark applications from smaller businesses that contained the prefix “Mc” or “Mac”, including McSleep Inns, McCoffee, and even a Scottish family restaurant called “McMunchies.” The strategy, often called trademark bullying, involves using legal challenges not necessarily because a claim is strong, but because the financial and operational burden of defending such challenges often forces smaller businesses to back down regardless of merit.
Pat McDonagh refused to back down. Instead, he counter-attacked.
Turning Defense into Offense
Rather than simply defending its trademark application, Supermac’s filed a cancellation action with the European Union Intellectual Property Office (EUIPO) in 2017, arguing that McDonald’s should lose its EU trademark on “Big Mac” entirely.
The legal basis was non-use. Under EU trademark law, a registered trademark can be cancelled if the owner fails to make genuine commercial use of it within a continuous five-year period. Supermac’s argued that McDonald’s had not sufficiently demonstrated genuine use of the “Big Mac” trademark in the EU, a bold claim, given that the Big Mac is arguably the world’s most famous burger.
What followed was a remarkable failure of evidence on McDonald’s part.
McDonald’s Shoots Itself in the Foot
To defend its trademark, McDonald’s submitted three categories of evidence:
- Affidavits from McDonald’s employees asserting that the Big Mac was sold in the EU.
- Brochures and printouts showing the Big Mac on menus.
- Wikipedia and website printouts referencing the Big Mac.
The EUIPO found this evidence deeply insufficient. Specifically:
- The affidavits were self-serving declarations from interested parties and were given limited evidentiary weight.
- The brochures and printouts were undated or could not be verified as having been used within the relevant period.
- Wikipedia and website screenshots are not accepted as proof of genuine commercial use. They are secondary sources, not business records.
Critically, McDonald’s failed to provide concrete evidence such as sales figures, invoices, delivery records, or verifiable point-of-sale data showing that the Big Mac was actively sold under that specific trademark in EU markets during the relevant period.
In January 2019, the EUIPO ruled in favor of Supermac’s, cancelling McDonald’s “Big Mac” EU trademark in its entirety for both restaurant services and food products.
McDonald’s appealed. In 2023, the EUIPO Board of Appeal largely upheld the original decision, cancelling the trademark for restaurant services (where McDonald’s evidence was found most deficient), while reinstating it in a narrower scope for certain food product categories, a partial but still significant victory for Supermac’s.
What Does This Mean Beyond the Courtroom?
Trademark Rights Are “Use It or Lose It”
This case is a powerful reminder that trademark registration is not a permanent shield. In the EU (and many other jurisdictions), registered trademarks must be actively and genuinely used in commerce. Businesses, especially large corporations managing vast trademark portfolios, must maintain proper commercial use records and documentation, or risk losing the very protections they rely on.
Practical takeaway: Conduct regular trademark audits. Ensure that evidence of genuine use, sales records, invoices, marketing materials with dates, is systematically archived for every registered mark.
Trademark Bullying Can Backfire Catastrophically
McDonald’s aggressive strategy to block Supermac’s expansion not only failed legally, it became a global PR event. The David vs. Goliath narrative attracted international media coverage, generating enormous brand awareness for Supermac’s at zero marketing cost. Supermac’s revenue and brand recognition outside Ireland grew significantly in the aftermath.
Practical takeaway: For large corporations, aggressive trademark opposition strategies carry reputational risk. For small businesses, a well-documented, legally sound counter-challenge can transform a defensive position into a brand-building opportunity.
The Quality of Evidence Is Everything
McDonald’s lost not because it had a weak trademark, but because it submitted weak evidence. This is a procedural and operational failure as much as a legal one. Had McDonald’s submitted proper commercial documentation, invoices, verified sales data, audited records, the outcome might have been different.
Practical takeaway: When registering or defending a trademark, treat evidence management as a core business process. Work with legal teams to establish documentation standards before disputes arise.
Smaller Businesses Have Real Legal Tools
Supermac’s success demonstrates that trademark law is not exclusively a weapon for well-resourced multinationals. The cancellation procedure at the EUIPO is a relatively accessible mechanism, and the non-use provision exists precisely to prevent “trademark squatting” and bullying. Small and medium enterprises have legal recourse, but must be willing to use it strategically.
Practical takeaway: SMEs facing trademark opposition should consult IP counsel not just on defense, but on whether offensive cancellation actions are viable. The cost of a well-targeted cancellation proceeding can be far less than a protracted opposition defense.
Trademark Bullying as a Business Strategy
The Supermac’s case sits within a well-recognized pattern in corporate trademark practice. Legal scholars and IP watchdogs have documented how large firms sometimes use trademark oppositions not to protect genuine rights, but to suppress competition or expansion by smaller players.
The International Trademark Association (INTA) and various national IP offices have increasingly scrutinized this behavior. Some jurisdictions have introduced provisions allowing recovery of legal fees in cases where trademark oppositions are found to be filed in bad faith.
For businesses operating internationally, understanding the difference between legitimate trademark enforcement and bullying, and knowing how to distinguish and respond to each, is an increasingly essential strategic competency.
Where Are They Now?
Supermac’s has continued to grow. The publicity from the case accelerated its brand profile internationally and emboldened further expansion efforts. Pat McDonagh has spoken openly about the case as a defining moment for the company, and Supermac’s has since been cited as a model of resilient brand strategy under legal pressure.
McDonald’s retained partial trademark rights following the 2023 appeal ruling, but the reputational damage and the legal precedent set by the case remain significant. The case is now widely cited in European IP law courses, business school curricula, and trademark practitioner guidance.
The Lesson Every Business Should Take Away
The Supermac’s vs. McDonald’s case is more than a feel-good underdog story. It is a practical lesson in how trademark law functions in the real world, where the outcome is determined not just by who filed first, but by who can prove genuine use, who maintains proper documentation, and who has the strategic courage to push back.
For business leaders, the case raises essential questions:
- Are your trademarks actively and documentably in use?
- Do you have the evidence to defend them if challenged?
- Are you aware of your options, offensive as well as defensive, when facing IP opposition?
In intellectual property, as in business, preparation and documentation are not bureaucratic formalities. They are competitive advantages. Supermac’s proved that, one Big Mac at a time.
