Does the Document Constitute a Single Source of Information

Date Published

Note: The information in this part only applies to applications filed before 1 April 2002.

Under sec 7(3), any prior art information used to establish a lack of inventive step has to be made publicly available in either:

  • a single document or through doing a single act; or

  • two or more related documents or doing two or more related acts, if the relationship between the documents or acts is such that a person skilled in the art would treat them as a single source of that information.

Some guidance on when two or more documents constitute a single source of information is provided in Nicaro Holdings Pty Ltd v Martin Engineering Co, 16 IPR 545. The conditions are the same as for novelty and are discussed in Mosaics and Related Documents.
