If $A$ is a ring with automorphism $\varphi$ and the skew Laurent series ring$A((x,\varphi ))$ is a right semidistributive semilocal ring then $A$ is aright semidistributive right Artinian ring. The Laurent series ring $A((x))$ isa right semidistributive semilocal ring if and only if $A$ is a rightsemidistributive right Artinian ring.  The study is supported by Russian Scientific Foundation (project16-11-10013).
