In Australia, patents are granted for inventions that provide a functional or technical solution to a problem. The key question is whether your invention involves a tangible, practical innovation — something that works in a new way, produces a useful result, or solves a real-world problem. If it does, there is a strong chance it can be patented.
What types of inventions are eligible?
Australian patent law takes a broad, principled approach to patentable subject matter. Rather than listing specific categories, the law asks whether the invention amounts to a "manner of manufacture" — a legal concept that has been interpreted flexibly by the courts over many decades. In practical terms, this means a wide range of inventions can qualify, including:
- Products and devices — physical items such as tools, machines, consumer products, medical devices, or components
- Methods and processes — new ways of doing something, including manufacturing processes, treatment methods, or testing procedures
- Systems — combinations of components or steps that work together to produce a useful result, including computer-implemented systems
- Compositions of matter — new chemical compounds, pharmaceutical formulations, materials, or mixtures
The common thread is that the invention must create an "artificially created state of affairs" with economic significance. In other words, it must be something practical, functional, and commercially useful — not merely a theoretical concept.
What cannot be patented?
While the scope of patentable subject matter is broad, there are clear exclusions. The following are generally not eligible for patent protection in Australia:
- Abstract ideas and theories — a concept or principle in its pure form, without any practical application or implementation, cannot be patented
- Mathematical models and algorithms — in isolation, these are considered discoveries rather than inventions
- Artistic and literary works — creative expressions are protected by copyright, not patents
- Mere discoveries — finding something that already exists in nature, without any practical application, is not patentable
- Mental processes and schemes — plans, rules, or methods of performing mental acts are not eligible unless they involve a technical implementation
- Human beings and biological processes — most naturally occurring genetic material and biological processes for generating human beings are excluded
The critical question is whether the invention provides a technical or functional solution to a problem — not whether it involves a clever idea.
The grey areas: software and business methods
Some of the most common questions about patentability arise in the areas of software, computer-implemented inventions, and business methods. These are not automatically excluded from patent protection in Australia, but they do face additional scrutiny.
A purely computerised business process — for example, a scheme for managing financial transactions that is simply implemented using generic computer hardware — is unlikely to be considered patentable. However, where software produces a technical effect or solves a technical problem in a technical manner, it may well qualify. The key is demonstrating that the invention goes beyond automating a known process and involves genuine technical innovation.
Recent developments in Australian case law have reinforced a flexible, substance-over-form approach. The courts have focused on whether the claimed invention, as a whole, produces an artificial state of affairs and a useful result — rather than applying rigid categorical exclusions. This means that computer-implemented inventions can be patentable, provided they demonstrate sufficient technical character.
We work closely with clients to frame software-related patent applications in the most technical manner possible, carefully identifying and articulating the technical features and how they interact with hardware, networks, or other technical systems.
Formulations and compositions
For inventions involving formulations of ingredients — whether in pharmaceuticals, food technology, cosmetics, or industrial applications — patentability often turns on whether the combination offers more than the sum of its known parts.
If each ingredient in a formulation simply contributes its known, expected properties, an examiner may characterise the claim as a "mere admixture" or an obvious combination. To strengthen the case for patentability, it is highly desirable to demonstrate that the ingredients interact in a synergistic way — producing benefits or effects beyond what would be expected from combining the individual components.
For formulations, the strongest patent applications demonstrate synergistic effects — where the combination achieves more than the sum of its parts.
Supporting evidence such as comparative test results, stability data, or efficacy studies can be valuable in establishing these effects and building a persuasive case during examination.
How to assess whether your invention is patentable
Before pursuing a patent application, it is worth considering a few practical questions:
- Is it functional? Does the invention solve a practical problem or achieve a useful technical result, rather than being purely aesthetic or conceptual?
- Can it be defined in technical terms? Can you describe the invention in terms of its technical features — what it does, how it works, and what makes it different from what came before?
- Is it new? Has the invention been publicly disclosed anywhere in the world before? Novelty is a fundamental requirement for patentability.
- Is it non-obvious? Would the invention have been obvious to a person skilled in the relevant field, based on what was already known?
If you can answer "yes" to the first two questions and are uncertain about the last two, that is often a good starting point. Assessing novelty and inventive step typically requires a more detailed analysis, which a patent attorney can assist with.

The boundaries of patentable subject matter can be nuanced, particularly in fields like software, biotechnology, and formulations. What matters most is how the invention is characterised and described in the patent application. A well-drafted application that clearly articulates the technical features and the problem being solved is far more likely to succeed than one that focuses on the concept at a high level.
