High Court Confirms the Law on Computer-Implemented Inventions

The position on computer-implemented inventions in Australia is now settled.

On 5 February 2026, the High Court of Australia refused the Commissioner of Patents’ application for special leave to appeal the Full Federal Court’s decision in the long-running Aristocrat litigation. The refusal means the Full Federal Court’s September 2025 reasoning stands as the definitive statement of Australian law on patentable subject matter for computer-implemented inventions.

When we previously reported on the Full Federal Court’s decision, it marked a significant and welcome clarification. The Court rejected the narrow “two-step” framework that had been applied in examination practice and reaffirmed the orthodox principles derived from longstanding High Court authority. However, some uncertainty remained while the possibility of a High Court appeal lingered.

That uncertainty has now been removed.

By declining special leave, the High Court has confirmed that the Full Court’s approach governs the assessment of patentable subject matter in this area. There will be no further appeal.

The key principle remains whether the claimed invention, considered as a whole, results in an artificially created state of affairs with economic utility. The Court made clear that it is impermissible to dissect a claim into its individual elements or to disregard computer implementation before conducting the eligibility analysis. The invention must be assessed in its entirety.

In practical terms, an abstract idea merely performed on a generic computer will not be patentable. However, where an abstract idea is implemented in a way that produces a concrete, artificial and useful result, it may constitute patentable subject matter.

Importantly, the decision confirms that computer-implemented inventions are not subject to a separate or elevated threshold. The same foundational test applies as for other technologies.

For innovators, this development provides welcome certainty. Over recent years, examination outcomes in this area had reflected a more restrictive interpretation, creating unpredictability for software-driven businesses. The High Court’s refusal to intervene now solidifies a clearer and more balanced approach.

Businesses developing software, fintech solutions, AI systems, gaming technologies and other digital platforms can proceed with greater confidence when incorporating patents into their commercialisation strategies.

With the Aristocrat matter now concluded, the law in Australia is settled. Computer-implemented inventions that create an artificially created state of affairs and deliver economic utility are capable of patent protection.
