Intellectual Property – Federal Circuit Reaffirms Existence of a Separate Written Description Requirement
MATR Sponsor (view all)
In an en banc opinion, the Federal Circuit held in Ariad Pharms v. Eli Lilly & Co., 2008-1248 (March 22, 2010) that 35 U.S.C. § 112 contains both a written description (“WD”) requirement and an enablement requirement and that these requirements are separate and distinct.
The holding of such separate and distinct requirements is not necessarily new – a separate written description requirement has existed at least since the court decided Regents of the University of California v. Eli Lilly & Co. in 1997 – the court drew a firm line and decisively articulated that confusion regarding the separateness of the requirements should be dismissed.
