To have a valid patent, an inventor must disclose sufficient detail in the specification to enable the patent, often referred to as the enablement requirement. To fulfill the enablement requirement, an inventor must disclose enough detail in the patent to teach a person of ordinary skill in the art to make the invention without undue experimentation. But an inventor cannot rely on the argument that one of ordinary skill in the art can fill in missing details from the specification. Indeed, recent case law demonstrates that inventors cannot rely on the person of ordinary skill in the art to serve as a substitute for missing information in the specification of the patent.
The case of Alza Corp v. Andrx Pharamaceuticals LLC, 603 F.3d 935 (Fed Cir. 2010), addressed this exact issue. For more information, please see a discussion of Alza.
