Purpose An essential part of the patent process, publication of patent specifications is required under the Patents Act 1990. Publication of specifications is part of the social contract to publically disclose inventions in exchange for the exclusive right to exploit the invention for the period of the patent. The published specifications also form part of the prior art base, which is used by the examination and opposition processes to determine eligibility for patents. Publication of a complete specification gives the applicant the same rights as they would have had if a patent for the invention had been granted on the day when the specification became open to public inspection (OPI). Content Australian AU-A, B & C patent specifications. Australian patent applications prior to acceptance (AU-A), applications that have been accepted (AU-B) and patent applications that have been accepted but were subsequently amended and therefore need to be republished (AU-C). Access and Security Publicly available
