"You can quote the game all you like, but even Eidos cannot copyright the words "Deus Ex Machina" as they literally mean something and aren't a "name". They can copyright it for a video game, but only a video game." What ever you think that you stated is not what you stated. What you stated was that Eidos could copyright the words for their game and Yamaha for their purposes (even though this is not a Yamaha design at all but the work of a student with no connection to Yamaha) of assigning it to a motorcycle. They would not be copyrighting the words, only the image of the words in a specific logotype. Now, you may be aware of the specifics of the law but your explanation is off base. Anyways, to state any relationship of the motorcycle concept to this game is a mere assumption. Especially given the broad geneology of the phrase. But then people tend to make assumptions founded in their own interests. You say this, I read... Sounds like your repeating yourself!
