If A is a ring with automorphism φ and the skew Laurent series ring A((x,φ)) is a right semidistributive semilocal ring then A is a right semidistributive right Artinian ring. The Laurent series ring A((x)) is a right semidistributive semilocal ring if and only if A is a right semidistributive right Artinian ring.
