The fundamental question: is software patentable in Australia?
The short answer is yes, software can be patented in Australia, but not all software qualifies. The Patents Act 1990 requires that a patentable invention be a "manner of manufacture" within the meaning of section 6 of the Statute of Monopolies. That phrase has centuries of judicial interpretation behind it, and it's the gateway through which every Australian patent application must pass — software included.
The challenge with software is that it often sits uncomfortably close to things that are traditionally excluded from patent protection: abstract ideas, mathematical algorithms, and schemes or plans. A pure algorithm or business method implemented in software won't typically qualify. What matters is whether the software produces a technical effect or solves a technical problem in a concrete way.
The Research Affiliates and Aristocrat legacy
To understand where we are in 2026, you need to understand the decisions that brought us here. The Full Federal Court's 2014 decision in Research Affiliates LLC v Commissioner of Patents was a watershed moment. The court found that a computer-implemented scheme for constructing a financial index was not patentable subject matter, essentially because the computer implementation was merely incidental to an otherwise abstract idea. The invention didn't lie in the way the computer operated but in the financial scheme itself.
Then came Commissioner of Patents v RPL Central Pty Ltd and Aristocrat Technologies Australia Pty Ltd v Commissioner of Patents, which further refined the test. The High Court's 2022 decision in Aristocrat was particularly significant, confirming that the mere implementation of an abstract idea on a computer is not enough to confer patentability. The High Court emphasised that the claimed invention must involve an "advance in computer technology" — not merely the use of a computer to implement an advance in some other field.
The key principle from Aristocrat is this: for software to be patentable in Australia, the invention must represent a genuine technical contribution to how a computer operates or how a technical problem is solved, rather than simply automating a business process or abstract concept.
This remains the governing standard heading into 2026, and IP Australia's examination practices reflect it closely.
What kinds of software innovations can be patented?
In practical terms, software patents are alive and well in Australia when the innovation genuinely lies in the technical realm. If your software improves data processing efficiency, enhances cybersecurity through a novel technical mechanism, optimises network communication protocols, or introduces a new method of image processing or machine learning architecture, you're in strong territory.
Consider a concrete example. If you've developed a new compression algorithm that reduces file sizes by thirty per cent compared to existing methods, that's a technical contribution to computer technology. The invention lies in how the computer processes data, not merely in applying a known technique to a new business context. That distinction is everything.
On the other hand, if you've built a brilliant app that matches dog walkers with dog owners using a standard recommendation engine, the innovation likely lies in the business model rather than in any technical advance. The fact that it runs on a smartphone doesn't make it a technical invention. You might have other IP protections available — trade marks, copyright in the code, or even design registrations for the interface — but a patent would be a stretch.
Artificial intelligence and the evolving frontier
One area generating significant interest is AI-related inventions. Machine learning models, neural network architectures, and AI-driven systems are increasingly the subject of patent applications in Australia. IP Australia has been engaging with the global conversation about AI and patents, and the position remains broadly consistent with the Aristocrat framework: if the AI innovation involves a technical advance in how the system operates, processes data, or solves a technical problem, it can be patentable.
What's becoming particularly interesting in 2026 is the question of AI-generated inventions — innovations devised by AI systems rather than human inventors. Following the Federal Court's decision in Thaler v Commissioner of Patents and the High Court's subsequent consideration, Australia requires a human inventor to be named on a patent application. This means that even if your AI system has produced something remarkable, a human must have contributed to the inventive process in a meaningful way for the innovation to be patentable.
Drafting software patent applications strategically
How you draft a software patent application matters enormously. A well-drafted application will frame the invention in terms of the technical problem being solved and the technical means by which it is solved. It will describe the interaction between software and hardware, the specific technical effects achieved, and why those effects represent an advance over what existed before.
Poorly drafted applications — particularly those that read like business plans with the word "computer" sprinkled throughout — are likely to face objections from IP Australia's examiners. We've seen many cases where a genuinely clever technical innovation was let down by a specification that emphasised the commercial application rather than the technical contribution.
If you're considering a software patent, think about your innovation from the computer's perspective, not the user's. What is the machine doing differently, and why is that technically significant?
Consider your broader IP strategy
It's also worth remembering that patents are only one part of the picture. Copyright automatically protects your source code and object code in Australia. Trade secrets can protect proprietary algorithms if you choose not to disclose them through the patent process. Registered designs may protect novel user interfaces. A thoughtful IP strategy considers all of these tools and deploys them where they're most effective.
Looking ahead
The fundamentals of software patentability in Australia are well established, but the edges continue to evolve. As AI, quantum computing, and other emerging technologies generate new categories of innovation, IP Australia and the courts will inevitably refine the boundaries of what constitutes a patentable technical contribution. Staying informed and getting early advice makes a real difference.
