Right. But, Bethesda already have a stellar reputation in the gaming community, their "The Elder Scrolls" series is many many orders of magnitude more well known than Mojang's upcoming game "Scrolls". The Elder Scrolls V: Skyrim is one of the most anticipated games this year.
Mojang and Notch have far far more to gain from this than Bethesda do.
it goes without saying that a 17 year old series is more well known than a new game. on the other hand, i have never referred to "The Elder Scrolls" as just "Scrolls". i've called it "Morrowind" or "Oblivion" and i'll probably refer to the new game as just "Skyrim". if i saw a game that was just called "Scrolls" i would not confuse it with Bethesda's games.
I'm not saying you would, I'm saying PR wise Mojang and Notch have everything to gain from settling this matter of law in a game of Quake, while Bethesda has very little.
