Can't a trademark owner give permission to someone to use it?
They could have easily just allowed him use of the name and if Ikea was ever in some kind of trademark lawsuit could have stated so. They chose not to for their own reasons, but the idea that business is forced to act this way and that Ingvar Kamprad is this grandfatherly old man who loves cheap furniture and not the ruthless head of a major world-wide corporation is asinine.
