Listening to the radio today and the DJ said he wasn't allowed to use the word World Cup because it was a trade mark!! Surely not? He kept calling it the world football festival. :-(
Its common usage and in the public domain we all use it. So unless everyone that mentions it will be sued, its utter bull.
They just can't use the brand to advertise Etc. Like a radio World Cup competition. Same way it costs to play a song. They can talk about it just as anyone can. But if they had a World Cup type competition etc there may be IP issues. Seems like a misunderstanding!!
