If anyone should want to- anyone can go to 'USPTO' (just google it) and you can look up(for free) anyones granted or applied for patent and/or trademark. You can see what catagory it is being applied to and whether it was granted or not.
Sometimes certain phrases can be trademarked, but only in certain catagories or for specific claims. Sometimes people will claim Trademark Applied for before they are actually granted the status and try to the application as a shield to anyone using their phrase, but that doesnt make it real or granted. Certain phrases CANT be trademarked simply due to already being in use for too long a time. Other phrases that may have been around before CAN be trademarked if they havent been used in a certain catagory and are very descriptive. A non-descriptive, generally used, non-catagory specific phrase will almost never be granted and can very easily be opposed in court in the event it is granted.
I wonder what the actual definition of the term they are using is, and if their place even qualifies under that definition.
I'm thinking this is a big ole publicity stunt that alot of people are responding to- even negative attention can be better than little to no attention.
