Sarah Bro wrote this bylined article about the Federal Circuit’s use of the Supreme Court’s “Raging Bull” decision in Petrella v. Metro-Goldwyn-Mayer, Inc. to decide whether laches remains a defense in patent litigation. Although the Court concluded that Congress intended for laches to apply in patent matters, Ms. Bro noted how it made a point that the laches defense must be harmonized with Petrella and other Supreme Court precedents.
