Pat McDonagh earned the nickname Supermac as an Irish teenager after a barnstorming performance in a Gaelic football match in the late 1960s.
The centre half-back guided his school, Carmelite college of Moate, County Westmeath, to victory over St Gerald’s, a more fancied team.
On Tuesday, half a century later, McDonagh prevailed in a different arena when his fast-food chain, Supermac’s, won a landmark legal battle against McDonald’s over the use of trademarks.
The Galway-based firm persuaded the European Union Intellectual Property Office (EUIPO) to cancel McDonald’s use of the “Big Mac” trademark, opening the way for Supermac to expand across Britain and continental Europe
Obviously the UK market could be a non runner in all this as they are leaving, so they may not have the pleasure of a Supermac Big Mac.
