Google LLC v. Oracle America, Inc.

Brief for R Street Institute et al. as Amici Curiae 15–20 (describing Oracle’s reimplementation of other APIs); see also Brief for American Antitrust Institute as Amicus Curiae 7 (“Copyright on largely functional elements of software that [have] become an industry standard gives a copyright holder anti-competitive power”).
