I don't realistically think Mojang could ever sue Bethesda over naming their game "The Elder Scrolls" even if they have a trademark on Scrolls, because Bethesda has had a trademark on "The Elder Scrolls" since 1994.
If Mojang ever tried to sue them, and I doubt they ever would, they would just look up the trademark history and see that Bethesda has had the name trademarked for 16 years at this point and has used it frequently enough to enforce the trademark.
