Lessons From Amgen v. Sanofi

Amgen provides a window on the Supreme Court approach to patent issues - look to history and established policy as our patent law is not code based but rather common law based. The Court noted that the "enablement requirement" is found essentially unchanged in every version of the patent law since 1790. While Amgen concerned the enablement provision, the same approach applies to patent eligibility, the "judicial exceptions," which have existed in our case law since the early 19^th century. In deciding Amgen the Supreme Court did not consider previous Federal Circuit decisions but looked to history of the enablement provision which involved Court decisions from the 19^th and early 20^th century. While Amgen was the Court's first antibody case, it found analogous cases which provided guidance as to how the enablement requirement had been interpreted. Since U.S. patent law is based on common law, this is the appropriate approach to provide the needed predictability.
