Supermac’s successful in latest UK trade mark dispute with McDonald's

Insights Food, Agribusiness & Beverage 17 Aug 2026 5 min read

Trade mark owners can face different outcomes across jurisdictions, even where the same marks and disputes are involved. Although further appeals are likely, a recent UKIPO ruling in favour of Supermac's may also support its UK expansion plans. Our Intellectual Property team examines the decision.

As we have reported previously, Supermac’s and McDonald’s have been engaged in an ongoing legal battle in the EU for many years. The most recent development at EU level is a decision by the EUIPO’s Board of Appeal in June 2026. It rejected Supermac’s application to register its name and logo for restaurant services in Class 43. The EUIPO’s Board of Appeal considered there was a likelihood of confusion between Supermac’s and McDonald’s Big Mac trade mark, for English and German speaking consumers. However, in a more recent decision from 31 July 2026, the UKIPO has reached the opposition conclusion. This UK development represents a major win for the Irish fast-food chain. It will offer encouragement to Supermac’s for its future UK growth and expansion plans.

Background

Supermac’s filed two UK trade mark applications in April 2021 to protect the word SUPERMAC’S and the logo:

Supermacs Logo Plain

Both applications protect the following Class 43 services: “Services for providing food and drink; restaurant services; fast-food restaurant services; canteens; self-service restaurant services; takeaway services; snack-bars.”

McDonald’s opposed both UK applications in December 2021. In doing so, it relied on a number of its pre-existing UK trade marks for BIG MAC, McDONALD’S, McCAFE and Grand Big Mac. Submissions were subsequently filed by both parties and a hearing in the matter took place in June 2025.

Family of marks

McDonald’s argued that the use of both “Mc” and “MAC” word elements in its trade marks was a “key identifier” for its brands. It claimed that these trade marks constituted a family of marks. It also contended the extensive and widespread use of Mc and MAC over a period of decades in relation to a product or service “creates a strong link to McDonald’s.” Regarding specific marks within the claimed family, McDonald’s argued that BIG MAC was first used in the UK for its signature burger product in 1974 when its first UK restaurant opened. After considering the family of marks criteria from the relevant case law, the UKIPO held that the McDonald’s marks relied on cannot be considered as a family due to:

  • Insufficient numbers
  • The positioning of the common feature, and
  • In the case of the BIG MAC and GRAND BIG MAC marks, not being consistently present in the market at the relevant date

Likelihood of confusion

In comparing the SUPERMAC’S trade marks with the McDONALD’S and McCAFE marks, the UKIPO held that the competing marks have significant visual, aural and conceptual differences. The Mc / MAC element is presented at different places within the marks which will impact how consumers recollect the marks, it held. According to the UKIPO, these differences are sufficient for a consumer not to directly confuse the marks. Also, the UKIPO did not consider it likely that consumers will indirectly confuse the marks.

In comparing the SUPERMAC’S trade marks with the BIG MAC and GRAND BIG MAC marks, the UKIPO held that the competing marks all share the same MAC ending. However, the UKIPO held that this similarity was outweighed by the differences at the beginning of the marks - namely the additional words BIG, GRAND BIG and SUPER. These were sufficient for the average consumer not to directly confuse the competing marks. Likewise, on the question of indirect confusion, if one mark was brought to mind by the others on the basis of the letters MAC, the UKIPO put this down to mere association not indirect confusion.

Unfair advantage and free riding

McDonald’s further claimed that Supermac’s would take unfair advantage due to “free riding” off the McDonald’s registrations relied on. In addition, it claimed that the SUPERMAC’S trade marks would be detrimental to the reputation and distinctive character of the McDonald’s brand. In deciding this claim, the UKIPO held that there was no doubt that McDonald’s has reputation in its McDONALD’S, McCAFE and BIG MAC marks. However, the differences between the McDONALD’S, McCAFE and the SUPERMAC’S marks were of a nature that no link would be made by the average consumer. Similarly, the differences between the goods protected by the BIG MAC UK trade mark and Supermac’s Class 43 services, and the differences between those competing marks meant that there would be no link. The UKIPO held that if consumers encountering the letters MAC within a trade mark were to bring the other mark to mind, it would be so fleeting that it would be ultimately ineffective.

Passing off

McDonald’s claims in passing off also failed. The UKIPO was satisfied that it had established goodwill in the signs McDONALD’S, McCAFE and BIG MAC. However, it did not find that the relevant public faced with the SUPERMAC’S trade marks, used for goods/services for which they have goodwill, will believe that there is a connection between the McDONALD’S trade marks and the SUPERMAC’S trade marks. The UKIPO held that the visual, aural and conceptual differences between the marks were significant. Accordingly, there was no logical progression between the competing trade marks capable of giving rise to misrepresentation.

Comment

The UKIPO decision represents a significant win for Supermac’s. However, it is likely to be appealed by McDonald’s. Therefore, this decision is unlikely to represent the end of the long-running dispute between the two competitor fast-food companies. It could be appealed to either the Appointed Person or to the High Court of England and Wales by McDonald’s. The EUIPO Board of Appeal decision on the other hand, could be appealed by either party to the General Court of the EU.

The most recent UKIPO decision serves as a reminder of the territorial nature of trade marks as assets. It also demonstrates that national IP offices do not always reach the same conclusions when presented with the same trade marks and disputes.The decision may also now offer an incentive to Supermac’s to expand its fast-food operations under the SUPERMAC’S trade marks in the UK in the short to medium term.

Does Supermac’s own any other UK trade marks for Supermac’s?
Yes, Supermac’s also filed a UK trade mark application for SUPERMAC’S in March 2014 protecting “Yeast; baking-powder; flavourings for snack foods (other than essential oils)” and “flavourings made from vegetables (other than essential oils)” in Class 30 only.
Is Supermac’s operational in the UK?
Not at present. While Supermac’s did operate up to six restaurants between 2007 and 2019 in Northern Ireland, the fast-food chain does not have any permanent operational restaurants in the UK as of August 2026.
At the end of this dispute, is it possible that the different results may arise in the EU and the UK?
Yes, this is a possibility as the national Court systems and trade mark offices are separate and distinct in the EU and the UK.
