Minerals Separation v. Hyde, 242 U.S. 261 (1916)
Briefly

by Dennis Crouch
Almost all the briefs filed in Amgen v. Sanofi cite to the 1916 Supreme Court decision in  Minerals Separation v. Hyde, 242 U.S. 261 (1916).It is an interesting little case that primarily focuses on obviousness (i.e., "invention"), but also touches upon inventorship and sufficiency of disclosure.
