Medimmune, Inc. v. Genentech, Inc. — Thomas, J., Dissenting

Summary

Justice Thomas dissents in MedImmune v. Genentech, arguing that a patent licensee in good standing lacks Article III standing to seek declaratory relief challenging patent validity without breaching the license. He contends the majority incorrectly extended Steffel v. Thompson to private contracts, allowing advisory opinions on affirmative defenses.
