Australian Patent Examination: How the Process Works

Examination does not begin automatically

Filing a standard patent application with IP Australia does not, on its own, put your invention in front of an examiner. Australia operates a request-based system: after filing, the application sits until examination is formally requested, either voluntarily by the applicant or in response to a direction issued by IP Australia. This two-step structure gives applicants a window to assess commercial value, refine claims, and manage cost before committing to the full examination process. It also means a deadline sits in the background, and there is more than one clock. The period for a voluntary request runs from filing, while a shorter period runs from the date IP Australia issues a direction to request examination, and letting the applicable period pass can cause the application to lapse. Which period applies depends on whether you are acting voluntarily or responding to a direction, so confirm both with IP Australia or a qualified local patent attorney rather than relying on a remembered figure.

Requesting examination attracts an official fee, and further fees can apply as the application progresses. Fee levels and categories change, so treat any figure you find as indicative only; official fees apply, and you should confirm the current amount with IP Australia or local counsel. For a practical walkthrough of getting an application on file in the first place, see our guide on how to file a patent in Australia, which sits under the broader Australian patents pillar.

The innovation patent is no longer an option

Applicants who researched Australian patents even a few years ago may recall a second-tier right called the innovation patent. It offered a faster route to a shorter term of protection and was popular for incremental improvements. Its lower bar was a distinct statutory test: it required only an innovative step rather than an inventive step, and an innovation patent was granted without substantive examination and could not be enforced until it had been examined and certified. That right has been phased out and is closed to new applications. You cannot file a fresh innovation patent today, no equivalent low-threshold right has replaced it, and strategies that once leaned on it need rethinking. In most cases the standard patent is now the route for a technical invention, while other forms of protection, such as registered designs, may suit the appearance of a product. We cover the wind-down in more detail in the abolition of the innovation patent. If an older adviser or template still points you towards an innovation patent, treat that as a sign the material is out of date.

What the examiner assesses

Once examination is under way, the examiner tests the application against the core requirements of patentability. The two that most often decide the outcome are novelty and inventive step. Novelty asks whether the invention has already been disclosed anywhere in the relevant prior art, so an earlier publication, sale, or public use can count against it, though a grace period may apply to some disclosures in the period before filing, notably the applicant's own. Whether a specific disclosure counts against you is fact-specific, so confirm the position with IP Australia or local counsel. Inventive step asks whether the invention would have been obvious to a person skilled in the relevant field, in light of the common general knowledge and the relevant prior art the skilled person could be expected to have found and understood. The examiner also considers other conditions, including whether the claimed subject matter is the kind of thing a patent can protect, an area that remains contested in Australian law, particularly for software and business methods, and where local counsel is worth consulting; and whether the specification describes the invention clearly and completely enough.

Examination is usually a dialogue rather than a single verdict. If the examiner raises objections, they issue a report, and the applicant can respond by arguing the point or amending the claims. Several rounds may follow. There is an overall period within which the objections must be resolved and the application brought into an acceptable state, and that period is finite, so responses should not be left to drift. Because the specifics turn on your file, confirm any applicable timeframe with IP Australia or your attorney.

Acceptance, then opposition, then grant

When the examiner is satisfied the requirements are met, the application is accepted, and acceptance is advertised publicly. Acceptance is a milestone, not the finish line. It opens a window during which a third party can oppose the grant, for example a competitor who believes the invention lacks novelty or an inventive step. If no opposition is filed, or an opposition is resolved in the applicant's favour, the patent proceeds to grant. This is also the stage at which the Australian route connects to international strategy: many applicants reach IP Australia by entering the Australian national phase from a Patent Cooperation Treaty application, and the way an application is handled here can echo choices made much earlier in that process.

Where this leaves you

IPEnvoy is not a law firm and does not provide legal advice; this is general information only. Patent examination turns on the precise facts of your invention and the current rules, both of which move. Confirm the current position with IP Australia and a qualified local IP professional before acting. If you would value a warm introduction to a vetted Australian patent attorney, IPEnvoy can help point you towards the right local expert for your situation.
