Asahi Kasei Kogyo KK’s Application: HL 1991

The House considered a case involving the issue of enablement of a particular peptide in a patent application.
Held: On the assumed facts that there had been a prior disclosure of the same invention neither the disclosed information nor common general knowledge would have enabled the skilled man to make it. The argument that the purpose of s2(3) was to prevent double patenting was rejected
Lord Oliver of Aylmerton said: ‘The Act does not contain any definition of the word ‘supported’ but some assistance can be obtained from the provisions of section 14(5) which require the claim in an application to be ‘supported’ by the description. That must, I think, involve the conclusion that if that which is contained in the description of the specification does not enable the claim to be established, it cannot be said to ‘support’ it, for the Act can hardly have contemplated a complete application for a patent lacking some of the material necessary to sustain the claims made. Since, therefore, subsection (3) of section 14 requires in terms that the specification disclose the invention in a way which will enable it to be performed by a person skilled in the art (i.e. it must contain an ‘enabling disclosure’) it follows that a description in an earlier application which contains no enabling disclosure will not ‘support’ the invention so as to enable it, as an invention, to claim priority from the date of that application under section 5(2)(a).’
