  In this paper we study the implications of the generalized Higuchi bound on
massive spin-two fields for the derivative of the scalar potential within
bimetric theory. In contrast to the recent de Sitter swampland conjecture, an
upper bound on the derivate of the scalar potential follows from the
generalized Higuchi bound. In combination, this leaves a window for the
derivate of the scalar potential. We discuss this bound in several
representative bimetric models and parameter regions.
