17 U.S.C. § 202 : US Code - Section 202: Ownership of copyright as distinct from ownership of material object

      Ownership of a copyright, or of any of the exclusive rights under
    a copyright, is distinct from ownership of any material object in
    which the work is embodied. Transfer of ownership of any material
    object, including the copy or phonorecord in which the work is
    first fixed, does not of itself convey any rights in the
    copyrighted work embodied in the object; nor, in the absence of an
    agreement, does transfer of ownership of a copyright or of any
    exclusive rights under a copyright convey property rights in any
    material object.
