J. E. M. Ag Supply, Inc., Dba Farm Advantage, Inc. v. Pioneer Hi-Bred International, Inc. — Scalia, J…

Summary

Scalia joins the Court, reasoning that Chakrabarty settled the ambiguity regarding composition of matter and plants, so the Plant Patent Act acts as an amendment governed by the canon against implied repeal. Justice Breyer, dissenting, would have held that specific plant statutes exclude utility patents.
