Although there does not appear to be a reported Sixth Circuit opinion explicitly adopting this approach, we have recognized its viability. See Murray Hill Publ'ns v. ABC Comm., (“[W]hen a single line of a larger copyrighted work is appropriated by an alleged infringer, the test is whether ‘the work is recognizable by an ordinary observer as having been taken from the copyrighted source’.”) (quoting Universal Pictures Co. v. Harold Lloyd Corp., (internal quotation marks omitted) and citing Whitney v. Ross Jungnickel, (“Here, only two lines are claimed to have been appropriated from plaintiffs' lyric․ This would not prevent recovery if the lines claimed to have been appropriated constitute an important and vital part of the two compositions rather than being merely incidental or trivial.”)). But, fragmented literal similarity has been applied by district courts in our circuit and, as noted above, by our sister circuits.
