Would it be possible to trademark the world scrolls alone?
But it would have to be restricted to a specific type of product - i.e. you aren't really trademarking the "word", but particular uses of it, for particular purposes.
e.g. "coke" is trademarked.
(This is obviously separate from the issue of whether a trademark for games called “The Elder Scrolls” also covers games called “Scrolls”.)
It’s a bit off-topic, really, since there only seems to be a trademark for “The Elder Scrolls”, not “Scrolls”. This is all about the possibility of confusion.
