Utah's oldest drive-in thater has filed suit in federal court claiming a California-based theater chain mis-appropriated its name.

The Riverdale Theatre Corp., which has operated a drive-in in Riverdale since 1941, brought suit against Mann Theatres.

The drive-in claims exclusive rights to use of word "Riverdale" in its name.  The court suit said Mann built a four-theater complex at the Riverdale Mall which it named the Riverdale Plaza Theaters.

Riverdale Drive-in acused Mann of "parasitical misappropriation" of the drive-in goodwill through use of "names which are deceptively similar."
