Abstract
In Star Athletica v. Varsity Brands, the Supreme Court recently unveiled a new approach to separability. Because copyright law protects expression, not function, aesthetic features of useful articles are eligible for copyright protection only if they are separable from the functional work in which they are incorporated. But the Copyright Act does not define separability, and Star Athletica is the latest judicial effort to try to fill that void. Unfortunately, the new separability is open to a wide range of critiques. Relatively low-hanging fruit are the vagueness and indeterminacy of the new test, the Court's unsatisfactory attempts to avoid defining "function," the threat of overprotection resulting from the opportunistic litigation the Court invites, and the uncertainty regarding the deterrent effects on overprotection of copyright's other limiting doctrines.
