At SaturnReturn. When copyrighting a name, you have to approach "Companys House" and pay them to do a name check on your chosen name. Say you chose "AirLicker" and wanted to have that copyrighted for use as a clothing label, but you discovered that there was a Lunderette chain called AirLicker for example. That doesnt mean that you vant use the name AirLicker for your clothing label. The copyright will cover a sector of industry only, to protect you from the unfair use of your chosen name/label.
For example, in the naughties, I registered a name for an urban youth magazine and had it copyrighted too. However, at the time there was a British company who had already copyrighted my magazines initials (UGC) for use in another industry. I checked with companys house and was told that the copyright for UGC was available for use in paper media only and got given a list of companys in various industries with the same initials as my UGC copyright. They all had copyrights too, pertaining specifically to their industries...
Copyright law is complicated. I couldnt for example, open a Snooker club and call it Coca-Cola Snooker... some giants are just too big to take on! ;) Coca-Cola have a registered trade mark, meaning that the brand Coca-Cola is exclusive to them, and cannot be used in any other industry around the world, period. Giants indeed :D
