Clarity for Software Patents in Australia
If you have been trying to secure an Australian patent for a computer-implemented invention (CII) over the last decade, you already know it’s been a frustrating, unpredictable rollercoaster. However, there is finally some welcome news for tech innovators. Following a series of landmark rulings culminating in early 2026, the Australian legal landscape for software patents has finally stabilised. The new approach steers away from restrictive tests toward a more sensible, holistic standard and provides essential clarity.
The Death of the "Advance in Computer Technology" Test
Australian patent examiners and courts have struggled for many years with how to assess whether software executing on standard computer hardware is patentable. This led to a problematic two-step test where patent applicants essentially had to prove their invention represented a specific "advance in computer technology". In September 2025, the Full Federal Court of Australia delivered a unanimous decision in Aristocrat Technologies Australia Pty Ltd v Commissioner of Patents [2025] FCAFC 131. This provided a significant and much-needed course correction for the software patent industry:
February 2026: The High Court Seals the Deal
While the September 2025 decision was a win for innovators, the ultimate test was whether it would survive a final challenge in the High Court. In February 2026, the High Court of Australia refused special leave to appeal the Full Federal Court's decision: Commissioner of Patents v Aristocrat Technologies Australia Pty Ltd (S153/2025). By refusing to hear the case, the High Court has effectively cemented the Full Federal Court's 2025 ruling as the definitive, authoritative law.
What This (Hopefully!) Means for Innovators in Australia
This sequence of events brings a decade of frustrating legal debate to a close. Here is the expected practical impact for businesses moving forward:
Will IP Australia Follow Suit?
In view of the High Court’s decision, the spotlight now shifts onto the Australian Patent Office (IP Australia). IP Australia has for many years maintained a notoriously restrictive examination practice regarding CIIs, frequently rejecting applications based on tests the courts have now dismantled.
The critical next step is for IP Australia to fall in line. The hope (and legal expectation) is that they will promptly and comprehensively update its Manual of Practice and Procedure to reflect the recent legal developments. Innovators and patent attorneys will be watching closely. The true test will be whether patent examiners abandon their historical resistance and begin applying the sensible, positive and holistic assessment in their day-to-day examination practice.

This provided a significant and much-needed course correction for the software patent industry:
- The Holistic Assessment Returns: The Court decisively rejected the restrictive two-step test. They ruled that an invention should not be artificially dissected into its "inventive" abstract parts and its "standard" generic computer parts. It must be judged as a complete, integrated system.
- Focus on the Result: The Court went back to foundational principles. The core question is simply whether the invention, properly characterised as a whole, is an abstract idea implemented on a computer to produce an artificial state of affairs and a useful result.
- Generic Hardware is Okay: The Court made it clear that you don't need to invent new computer hardware or advance computer science itself to obtain a patent. If a system satisfies the above-referenced test, it is patent eligible subject matter.

This sequence of events brings a decade of frustrating legal debate to a close. Here is the expected practical impact for businesses moving forward:
- Broader Protection: Software-enabled innovations in fields entirely outside of core computer science (such as gaming, fintech, logistics, agriculture or consumer tech) now have a much clearer path to patentability;
- Greater Certainty: Patent attorneys and applicants can now draft claims based on settled principles rather than trying to navigate constantly moving legal goalposts;
- Abstract Ideas are still out: It is important to note that simply taking an abstract business scheme, pure mental step or mathematical formula and saying "do it on a computer" will still not be eligible for a patent. The software implementation must be integral to how the system functions and create an artificial state of affairs with a useful outcome.
