The decision canvasses many of the same issues tackled by the US Supreme Court in its recent Alice Corporation v CLS Bank ruling.
In essence, the Australian court addressed the question of whether an invention that would otherwise be ineligible for patent protection – in this case, a scheme for generating a financial index which can be used, for example, to measure the rise and fall in value of an investment portfolio – becomes patentable when implemented in software. This has been an open question in Australia since the court’s 2006 decision in Grant v Commissioner of Patents [2006] FCAFC 120, in which it found that an asset protection method was ineligible for patenting. In that case, however, the court was not required to consider whether the outcome may have been different had all or part of the method been performed using a computer.
In the Grant case the court stated that, for a claimed invention to be patent-eligible, a ‘physical effect in the sense of a concrete effect or phenomenon or manifestation or transformation is required’. Where a computer is involved there is always, of necessity, some physical effect or change of state, at least within the electronics of the machine. The question that the court has not previously addressed is whether or not this is sufficient to confer patent-eligibility?
In Research Affiliates, the court has answered this question in the negative, finding that describing a scheme – no matter how ingenious it may be – that is not itself eligible for patenting, and merely giving directions to implement it on a standard computer is not sufficiently transformative.
However, while – subject to any appeal to the High Court – this decision would seem to spell an end to ‘do it on a computer’ patent claims in Australia, the Full Court has been cautious (certainly more so that the US Supreme Court in its recent Alice v CLS Bank decision) to ensure that most computer-implemented inventions remain patent-eligible in Australia.
