Supermac's will appeal the European ruling that it is not allowed to trade under its current name in Europe.
The company lost a court battle to sell using the Supermac's brand in Europe, partly because of its similarity to McDonalds.
The Irish Independent reports that the Irish chain will appeal the decision.
They have also withdrawn their trademark application in Australia, however Supermac's bosses say this is purely tactical and they will re-apply in a few months.
