Country Guide: Filing a Patent in Australia

Australia is a mid-sized but strategically significant patent jurisdiction — the dominant economy in the Asia-Pacific region outside East Asia, a common law country with sophisticated courts, and one of the few major jurisdictions that has genuinely and substantially reformed its patent system in the past decade. For inventors with technology relevant to mining, agriculture, biotechnology, medical devices, software, clean energy, and consumer products — sectors where Australian companies are globally active — Australian patent protection provides real commercial value.

Australia is also the most natural first international filing destination for inventors in the Asia-Pacific who are not yet ready to commit to Japan, China, or Korea — because its system is accessible, prosecutable in English, and its courts are experienced and predictable.

The Hard Truth About Australian Patents

Australia has done something unusual among major patent jurisdictions: it has deliberately and publicly tightened its patent system over the past decade, making it harder to obtain patents and easier to challenge them. Two reforms in particular changed the landscape:

The Raising the Bar Act (2013) overhauled patent examination standards, bringing Australian requirements closer to EPO and US levels. Before 2013, Australian patents were frequently granted on inventions that would have failed examination at the EPO or USPTO. Post-2013, examination is more rigorous — examiners apply a higher inventive step standard, require more specific enablement, and scrutinise claim breadth more carefully.

The Innovation Patent (abolished 2021): Australia's innovation patent — a fast, low-inventiveness-threshold patent analogous to Germany's utility model — was abolished in August 2021. Applications filed before that date remained valid and may still be in force, but no new innovation patents can be filed. This leaves Australia without a utility-model equivalent — standard patents are now the only route, with full substantive examination required.

The practical implication: Australian prosecution has become more demanding than it was before 2013. Claims that would have been readily allowed before the Raising the Bar reforms may now receive substantive rejections. Budget for more prosecution rounds than you might expect, particularly for broad software or method claims.

IP Australia: Overview

IP Australia is the government agency responsible for administering intellectual property rights, including patents, trade marks, designs, and plant breeders' rights. It is headquartered in Canberra and processes approximately 30,000–35,000 patent applications per year.

Types of patent protection in Australia:

Standard Patent:

• Term: 20 years from filing date (25 years for pharmaceutical patents with an extension of term)
• Examination: Full substantive examination
• Eligible subject matter: Manner of manufacture — a concept derived from the English Statute of Monopolies (1624) and interpreted through Australian case law

Plant Breeder's Rights (PBR): A separate protection system for new plant varieties, not a patent. Term: 20–25 years depending on variety type.

What Is Patentable in Australia: The Manner of Manufacture Test

Australia's patentability threshold is distinctive. Rather than the US "useful process, machine, manufacture or composition of matter" standard or the EPO's "technical character" requirement, Australia applies the manner of manufacture test — a concept rooted in 17th-century English common law but interpreted through a body of Australian case law that has evolved significantly.

The key principles from Australian patent case law:

An artificially created state of affairs with economic significance — the twin requirements from NRDC v Commissioner of Patents [1959] — form the baseline. An invention must produce a result that is artificial (not a naturally occurring phenomenon) and commercially applicable.

Software patents in Australia: The manner of manufacture test has produced some of Australia's most contested patent jurisprudence. A series of cases — including Research Affiliates LLC v Commissioner of Patents [2014] and Commissioner of Patents v RPL Central Pty Ltd [2015] — significantly restricted software and business method patents. The general principle that emerged: a computer-implemented invention is patentable only if it involves a physical transformation or produces a result in the physical world, or where the software improves the computer's technical functioning. A software implementation of an abstract idea or business method without more is not patentable.

The High Court's 2021 decision in Aristocrat Technologies Australia Pty Ltd v Commissioner of Patents added further nuance specifically for gaming machines, but left broader questions about computer-implemented inventions partially unresolved. Australian software patent prosecution requires careful attention to the manner of manufacture threshold and may require different claim structuring from US equivalents.

Pharmaceutical patents and the extension of term: The Patents Act provides for an extension of term of up to 5 years for pharmaceutical patents that have experienced regulatory delays in obtaining marketing approval. Applications for extension must be filed within 6 months of first regulatory approval in Australia or within 6 months of grant, whichever is later.

Biological inventions: Isolated biological materials (genes, proteins) are patentable in Australia, provided they involve a human intervention that creates an artificially created state of affairs — a position that differs from the US post-Myriad position (which excludes naturally occurring gene sequences). Australian patent law has not yet definitively addressed isolated genes in the same way the US Supreme Court did in Association for Molecular Pathology v Myriad Genetics (2013).

The Filing Process

Route 1: Direct IP Australia Filing

File a standard patent application directly at IP Australia. All applications are in English (or must be translated into English). IP Australia operates an online filing portal (eServices).

Filing fees (standard patent, individual/small entity):

• Provisional application: AUD $110 (establishes priority date, 12-month window)
• Standard application: AUD $370 online filing
• Examination request: AUD $490
• Additional claims fees: AUD $110 per claim beyond 20

IP Australia offers a 50% fee reduction for small entities and individuals — one of the most accessible fee reduction systems of any major patent office.

Route 2: PCT National Phase Entry

The most common route for foreign applicants. PCT national phase entry deadline at IP Australia is 31 months from the international priority date.

National phase entry requirements:

• Standard application form
• Payment of national entry fees
• No translation required (English language is sufficient)
• Appointment of an Australian patent attorney or registered patent attorney is required for foreign applicants

The Provisional Application: Australia's Key Tool

Australia's provisional specification system is well-developed and widely used. A provisional application:

• Establishes a 12-month priority period from the provisional filing date
• Can be brief and informal — a clear description of the invention is sufficient
• Costs AUD $110 in government fees
• Gives 12 months to assess commercial viability and prepare the complete specification

Australia's provisional system closely mirrors the US provisional, making it a natural complement to a US-first provisional filing strategy. An inventor who files a US provisional on Day 1 can file an Australian provisional simultaneously (or within 12 months claiming US priority) and have parallel priority dates in both jurisdictions — the starting point for a global PCT strategy.

Request for Examination

Substantive examination of an Australian standard patent application must be requested within 5 years of the filing date — one of the longest examination request windows of any major patent office, giving substantial flexibility to defer examination costs.

In practice, however, delaying examination leaves the application in a pending state that competitors can monitor, creates uncertainty about the scope of eventual claims, and delays grant. Many applicants request examination early rather than waiting the full 5 years.

Accelerated examination: IP Australia offers a fast-track examination programme. Applications processed under the PPH (Patent Prosecution Highway) agreement — where a related application has already been allowed at a partner office (USPTO, EPO, JPO, KIPO, and others) — are eligible for expedited examination at IP Australia. The PPH programme can reduce Australian examination time dramatically — a first examination action within 3–6 months rather than 12–18 months.

Examination at IP Australia

What Examiners Assess

Australian patent examiners apply the post-Raising the Bar standards:

Novelty (section 18(1)(b)(i)): The invention must be novel — not disclosed in a single prior art document before the priority date. The novelty test is broadly consistent with international standards.

Inventive step (section 18(1)(b)(ii)): The invention must not be obvious to a person skilled in the relevant art. Post-Raising the Bar, the inventive step standard was explicitly raised to be consistent with the EPO's approach — more demanding than the pre-2013 Australian standard. Examiners now consider what was common general knowledge in the art and what was directly ascertainable from prior art documents.

Manner of manufacture: The invention must be a manner of manufacture within the meaning of section 6 of the Statute of Monopolies. Examiners apply the case law framework discussed above, particularly for software, business method, and computer-implemented claims.

Utility (section 18(1)(c)): The invention must be useful — it must produce a result useful to the public. This is a low bar for most inventions.

Full description (section 40(2)(a)): The specification must fully describe the invention and the best method of performing it known to the applicant at filing. This mirrors the US best mode requirement.

Clear claims (section 40(3)): Claims must be clear and succinct and fairly based on the matter described in the specification.

A Worked Prosecution Scenario

An inventor based in Singapore filed a PCT application for a machine-learning algorithm that optimises energy consumption in industrial HVAC systems. On entering the Australian national phase, she received a first examination report raising two issues:

Issue 1 (manner of manufacture): The examiner questioned whether the claimed method — which described a series of algorithmic steps for optimising HVAC parameters based on sensor inputs — was a manner of manufacture, citing the Research Affiliates and RPL Central decisions.

Issue 2 (inventive step): The examiner combined two prior art documents (a 2019 conference paper on ML-based building energy management and a US patent on adaptive HVAC control) to argue the claimed method was obvious.

Response:

Manner of manufacture: The applicant's attorney argued that the invention was not a mere abstract algorithm — it produced a concrete physical result (reduced energy consumption in a physical HVAC system) and operated through specific physical sensors and actuators. The response cited Encompass Corporation Pty Ltd v InfoTrack Pty Ltd [2019] FCA 421, which confirmed that computer-implemented inventions producing tangible real-world outcomes could constitute a manner of manufacture. The claims were amended to explicitly recite the physical sensors, the industrial HVAC system components, and the measurable reduction in energy consumption — moving the claim away from abstract algorithm language toward a technically grounded system claim.

Inventive step: The applicant argued that the 2019 conference paper did not disclose the specific combination of real-time sensor fusion with predictive multi-step optimisation that characterised the invention, and that the US patent operated in a fundamentally different control paradigm (reactive rather than predictive). An expert declaration from an HVAC systems engineer confirmed that the specific predictive combination was not obvious to a skilled engineer in 2019.

Result: IP Australia allowed the amended claims after one further exchange. The granted patent had structurally specific system claims that clearly defined the physical components, complemented by method claims tied to the physical operation of the HVAC system.

The lesson: Australian software and AI patent prosecution requires claims that anchor the invention in physical reality — sensors, actuators, measurable physical outcomes. The manner of manufacture analysis rewards specificity and penalises abstraction.

Enforcement in Australia

The Federal Court of Australia

Patent infringement and validity disputes are heard by the Federal Court of Australia, which has dedicated patent judges with deep technical expertise. The court sits in Sydney, Melbourne, Brisbane, and other capital cities.

Timeline: First-instance patent cases in Australia typically take 2–4 years from filing to judgment — comparable to UK High Court proceedings and faster than US district court litigation for complex cases.

Costs: Patent litigation in Australia operates on a costs-follow-the-event basis (the losing party pays a portion of the winning party's costs). Realistic first-instance costs are AUD $500,000–$3,000,000 per side for contested proceedings, substantially lower than US litigation but higher than German proceedings.

Cross-examination and discovery: Australian patent trials include documentary discovery and witness cross-examination, similar to UK proceedings. Expert witnesses on both sides are common in technical patent disputes.

Preliminary Injunctions

Interlocutory injunctions are available in Australia and are assessed under the American Cyanamid test (as adopted in Australia): (1) serious question to be tried; (2) balance of convenience; (3) undertaking as to damages. Preliminary injunctions in Australian patent cases require demonstrating that damages would be an inadequate remedy — a relatively high bar. They are granted in clear cases of infringement but are not as routinely available as in Germany.

The Innovation Patent Legacy

The now-abolished innovation patent created a two-tier patent system for approximately 20 years. Patents granted under the innovation patent regime remain valid and enforceable until their expiry (maximum 8-year term from filing). Companies and inventors monitoring the Australian IP landscape should be aware that in-force innovation patents — with lower inventiveness thresholds than standard patents — may still exist in their technology area and may be enforceable until approximately 2029 for the latest-filed innovation patents.

Australia-Specific Strategic Considerations

Use the PPH to accelerate Australian prosecution. If your US, EPO, or JPO application has been allowed, filing a PPH request at IP Australia simultaneously with the examination request dramatically reduces examination time. For inventors who receive early allowance in the US or Japan, this turns Australian prosecution into a near-formality.

File Australian provisional before any public disclosure. Australia has a 12-month grace period for the inventor's own disclosures — but as always, relying on grace periods for international protection is inadvisable. The Australian provisional is inexpensive (AUD $110) and establishes an Australian priority date that can be claimed globally through PCT.

Monitor the innovation patent legacy portfolio. In competitive technology areas, check IP Australia's AusPat database for in-force innovation patents that might create FTO issues. Their lower inventiveness threshold means some may cover concepts that would not have survived standard patent examination — but they remain enforceable.

Australia as a gateway to the Pacific region. An Australian patent creates a foundation from which to approach New Zealand (whose Intellectual Property Office accepts applications in English and processes relatively quickly), Pacific Island nations, and ASEAN members. For inventors building Pacific Rim distribution networks, Australian IP protection anchors the regional portfolio.

Cost Summary

Australian prosecution costs in AUD are competitive relative to the US and Europe. Attorney hourly rates for qualified Australian patent attorneys typically range AUD $300–$600 per hour — moderate by international standards.
