No, because against all reason and logic it really happened. Had to go to snopes.com to make sure, but way back in 1990 the state* of Kentucky registered its own name as a trademark, and for a long time afterward managed to scare a lot of businesses-- notably KFC-- into renaming themselves or else coughing up a lot of money for use of the name. So far I haven't been able to find out if it was registered nationally or only within the state, which has its own trademark office. Hard to believe they'd manage to pull it off nationally, or there would immediately have been 49 copycats.
* Commonwealth, if you want to be snarky about it.
