The Evolution of Sufficiency in Common Law

LSE Legal Studies Working Paper No. 6/2013
The requirement of disclosure in the patent specification is commonly presented as an essential arm of the patent bargain. This paper tests the assumption that disclosure requirements in a number of common law jurisdictions continue to reflect this and other shared origins of this doctrine. Instead we see forces such as Europeanisation and sector-specificity produce divergence and confusion over the purpose of sufficiency, particularly in the context of adjacent patentability criteria such as utility and nonobviousness. The result is a complex expression of this requirement that has eroded the normative strength of this doctrine as originally expressed in Liardet v Johnson.
