A federal appeals court has reinstated a copyright infringement claim of a songwriter who says the “Iron Man” theme he composed for a television adaptation of Marvel superheroes comics in the 1960s was illegally appropriated by hip hop artist Ghostface Killah.

The U.S. Court of Appeals for the Second Circuit held Thursday that Jack Urbont’s claim of a federal Copyright Act violation was strong enough to withstand a motion for summary judgment from defendants Sony Music and Razor Sharp Records.
