&gt; But what interests me more about this case is that the article expects an Australian court decision to be taken as global jurisprudence. What&#x27;s the logic behind that?<p>I wondered that, too.  But in a parallel comment, ihodes pointed out that this was already ruled unpatentable by the US court system.  Courts do keep an eye on decisions from other nations; if they find the logic convincing, they&#x27;re likely to adopt it.  So if the US and Australia are following the same logic, it&#x27;s likely to be adopted pretty much universally.
