In this paper we prove the existence of infinitely many saddle-shaped positive solutions for non-cooperative nonlinear elliptic systems with bistable nonlinearities in the phaseseparation regime. As an example, we prove that the systemhas infinitely many saddle-shape solutions in dimension 2 or higher. This is in sharp contrast with the case Λ ∈ (0, 1], for which, on the contrary, only constant solutions exist.
