Basic filing requirements

In Australia, no power of attorney or authorisation of agent form is required.

The following information is required to file a patent application in Australia (which is not a national phase entry):

  • the applicant's full name and address;
  • the inventor's names and addresses;
  • a copy of the patent specification with drawings (preferably in electronic format) and a verified translation of the specification if not in English; and
  • details of any convention priority claim.

If entering the national phase in Australia, the following information is required:

  • a copy of the published international specification;
  • a copy of any Article 19 amendments;
  • a copy of the International Preliminary Examination Report with any Article 34 amendments; and
  • a verified translation of the published specification and any amended pages if not in English.

Before the patent application will be accepted the following information is required:

  • details of how the applicant derived title from the inventor;
  • a certified copy of any priority application (note that this is not normally required for national phase entry); and
  • a verified translation of any priority application which is not in English (note that this is also required for national phase entry).

Considering challenging an Australian patent?

A significant issue that our clients regularly face is in relation to third party challenges to patent rights and knowing when to initiate, or how to defend, proceedings. Adopting the right strategy is critical to achieving your goals and improving your likelihood of prevailing in any third party challenge.

The following mechanisms are available for challenging a patent application or patent in Australia:

  • Third party observations This is an ex parte process in which a third party notifies IP Australia of prior art relevant to a pending application. The grounds are limited to novelty and inventive step, and the notice is supported by written submissions. We generally would recommend filing a section 27 notice in very limited circumstances, where there is a novelty-destroying document (as it is difficult to invalidate claims on the ground of lacking an inventive step on an ex parte basis), and on the basis that a narrowing claim amendment to restore novelty would also remove any potential commercial threat.
  • Re-examination This is also an ex parte process, which may be initiated at any time after acceptance (allowance) of a patent application, including after grant. The grounds for re-examination are broader than those available for third party observations, and include patentable subject matter, utility, support, sufficiency and clarity, in addition to novelty and inventive step. However, the outcome of re-examination largely depends on the Examiner's reading of the patent specification and any prior art documents, and the patent applicant will typically be given an opportunity to propose amendments to overcome any ground of invalidity. For this reason, we generally do not recommend re-examination unless there is a very strong case and it is likely that an amendment to restore validity would also remove any potential commercial risk the patent poses.
  • Opposition Australia has pre-grant inter partes opposition proceedings, involving expert evidence from each party in the form of declarations by persons skilled in the art, which are decided by a Delegate of the Commissioner of Patents following an oral hearing. A notice of opposition may be filed within three months of the date that acceptance (allowance) of the application is advertised in the Official Journal of Patents. Commencing opposition proceedings may be appropriate if you wish to invalidate one or more of the claims before grant of a patent, or if you wish to challenge the applicant's entitlement to the invention. An opposition to the grant of a patent is significantly cheaper than seeking revocation of a patent before the courts, and may be used as a cost-effective means to test the strength of the applicant's case, particularly for corresponding litigation or challenges in other jurisdictions.
  • Revocation This is an inter partes procedure in which a third party may apply to the Federal Court of Australia for an order revoking a patent at any time after grant until the patent expires. The likelihood of successfully challenging a patent on the basis of prior art is increased during revocation proceedings, particularly if inventive step is a primary ground, due to the availability of pre-trial discovery and the evidence and cross-examination of experts at trial. However, this must be balanced with the commercial imperatives and the considerable cost of revocation proceedings, compared with alternative options for challenging the patent before IP Australia.

In our experience, before commencing an action to challenge a patent, it is crucial to identify which mechanism best aligns with your circumstances and commercial goals, and to ensure that you have a clear strategy in place, to maximise the likelihood of successfully achieving those goals.
