Think of Iceland and you think of cold weather, hot springs and Englands Euro 2016 humiliation. But for all their footballing heroics, it’s the Icelandic football fans who’ve found themselves in hot water over a trade mark infringement.

An Icelandic cartoonist has found that he can't sell T-shirts featuring the chant made famous by the country's football fans, because the word has been registered as a trademark.

Hugleikur Dagsson produced the shirts featuring the "Hú" chant to mark the country's participation in this years World Cup finals in Russia.

I spoke to Neville Walker, the Leading European & UK Chartered Patent Attorney at ipconsult, to find out more about how football chants could, increasingly, become the subject of trademark disputes.
