Australian Patent Examination Process

The Australian patent examination process is a structured and legally rigorous framework designed to ensure that patent rights are granted only for inventions that meet the statutory requirements of patentability. For applicants, understanding how this process operates is essential. Each stage carries strict deadlines and substantive legal consequences that directly affect whether a patent is granted and, if so, how strong and enforceable that patent will be.

Laying the Groundwork: Preparing a Strong Patent Application

Before the formal examination process even begins, the foundation for a patent must be laid with a meticulously prepared patent application. The strength and enforceability of a future patent are closely tied to the quality and detail of the initial application.

In Australia, the process typically begins with the filing of a provisional patent application. This is a strategic first step that establishes a priority date for the invention, which is the benchmark against which the novelty and inventiveness of the invention are assessed. Securing an early priority date is crucial, as any public disclosure made before that date, by the applicant or others, can be fatal to patentability.

A provisional application provides a 12-month period to further develop the invention, conduct market research, and decide on the commercial viability of the innovation, all while being able to claim “patent pending” status. However, the provisional application must disclose the invention in substance. Only material adequately disclosed in the provisional application can later be relied upon, and deficiencies at this stage may limit the scope of protection available in the complete application.

Within 12 months of filing the provisional application, a complete specification must be filed to continue the process. The complete specification is the core legal document. It must describe the invention clearly and completely, disclose the best method known to the applicant of performing the invention, and conclude with claims that define the legal scope of protection. Drafting this document requires careful judgment to balance commercial breadth against legal defensibility.

Patentability Requirements

To be patentable in Australia, an invention must meet several key requirements. It must be a manner of manufacture, meaning it falls within patent-eligible subject matter i.e., it must be a product, device, substance, or process. Abstract ideas, mathematical models, or artistic creations, for example, are generally not patentable.

The invention must also be novel, meaning it has not been publicly disclosed in any form, anywhere in the world, before the priority date of the application. Furthermore, the invention must involve an inventive step, meaning it is not obvious to a person skilled in the relevant field. Finally, the invention must be useful, meaning it has a practical application in industry. 

Failure to satisfy any one of these requirements will prevent acceptance, regardless of the commercial value of the invention.

Initiating the Examination Process

Unlike some jurisdictions, the examination of a standard patent application in Australia is not automatic. A formal request for examination must be filed, together with the prescribed fee.

This request can be made at any time after filing the complete application, but it must be made within five years of the filing date. If examination is not requested within this period, the application will lapse.

Typically, IP Australia issues a direction to request examination approximately two years after the complete application is filed. Once such a direction is issued, the Applicant has two months to make the request.

Expedited Examination

In certain circumstances, an applicant may request expedited examination. If granted, the first examination report may issue significantly earlier than under the standard timeframe.

Expedited examination may be appropriate where early grant is required for commercialization, licensing, enforcement, or investment purposes, or where the invention falls within recognized categories such as environmentally beneficial technologies. No additional official fee applies, but the request must be properly justified.

Substantive Examination

Once examination is requested, the patent application is assigned to a patent examiner at IP Australia who is an expert in the relevant field of technology. The examiner conducts a thorough review of the application to ensure it complies with the requirements of the Australian Patents Act. This includes a search for prior arts, any publicly available information that may be relevant to the novelty and inventiveness of the invention. The examiner assesses the application for compliance with all statutory requirements, including patentable subject matter, novelty, inventive step, clarity, support, and sufficiency of disclosure.

It is common for the examiner to issue one or more examination reports including objections. Receiving an examination report is a normal part of the process and should not be a cause for alarm. It is the beginning of a dialogue with the patent office, and it provides an opportunity to refine the application and argue the merits of the invention.

Responding to an Examination Report

Upon issuance of the examination report, the Applicant has a period of 12 months from the date of issuance to overcome all the objections. If the objections are not resolved within this timeframe, the application will lapse.

Responses typically involve a combination of legal argument and amendments to the claims or specification. Amendments must not introduce new matter and must be carefully framed to overcome objections while preserving meaningful claim scope.

This phase is often decisive, as the manner in which objections are addressed will directly affect both the prospects of acceptance and the ultimate strength of the patent.

The quality of the response often determines the outcome of examination. Poorly reasoned arguments or excessive claim narrowing can lead to avoidable loss of scope or prolonged prosecution.

Further Examination and Dialogue

It is common for examination to involve more than one report. The examiner may maintain objections, raise new issues arising from amendments, or accept some claims while objecting to others.

Applicants may request interviews or telephone hearings with the examiner to clarify issues, resolve misunderstandings, or streamline prosecution. These interactions can be valuable in efficiently progressing an application toward acceptance.

Acceptance following Examination

Once the examiner is satisfied that all objections have been overcome, IP Australia issues a Notice of Acceptance. Acceptance reflects the examiner’s conclusion that the application complies with the Act.

Acceptance is advertised, triggering a three-month opposition period. If no opposition is filed, or any opposition is resolved, the application proceeds to grant.

Why work with us?

The patent examination process in Australia is a comprehensive and rigorous one, designed to ensure the integrity of the patent system. While it can be a complex and challenging journey, it is a journey that you do not have to undertake alone.

Patent examination is the decisive stage of the Australian patenting process. It is during examination, not filing, that patentability is tested, claim scope is refined, and the enforceability of future rights is determined. Successful examination depends on a clear understanding of examiner practice, statutory requirements, and strategic response to objections.

Our firm has a deep understanding of Australian patent law and a wealth of experience in navigating the examination process. We are committed to providing you with the highest quality advice and representation at every step, from the initial drafting of your application to the final grant of your patent and beyond.
