Welcome to the new version of the Patents Manual. Please note there are changes to the numbering and sequence of the chapters and pages in the manual. You are encouraged to take the time to explore and familiarise yourself with this new structure.

8.5.4 Common General Knowledge

Date Published

For novelty, a citation is construed as at its date of publication to the exclusion of information subsequently discovered. For inventive step, the citation is construed by the person skilled in the art when trying to solve the problem, i.e. at the priority date of the claims being examined. This means that for the purposes of inventive step, the disclosure of a citation may be effectively extended by having regard to subsequent common general knowledge in Australia developed in the period between the publication date of the citation and the priority date of the claim under consideration.
