It's important to note Notch not only offered dropping the trademarking of "Scrolls", he also offered adding a subtitle or new words to the game title to not make it just "Scrolls" (on top of the non-trademarking stuff).
Bethesda/Zenimax essentially sues to prevent Mojang from using the word "Scrolls" at all, in a game which is all about, well, scrolls.
