Inventive step is hard. It really is. I have worked with and around patents for nearly 20 years, the majority as a practising patent attorney. I have been an inventor, I have studied, practised and taught patent law, and I have thought and written about patents and patent law for many years. And I still think that inventive step is genuinely hard. If anyone tells you otherwise they are either a liar or a fool.
Just stop and think for a moment about the job that the law of inventive step (or obviousness, nonobviousness – whatever your preferred formulation, the problem is substantially the same) is required to achieve. Firstly, it is supposed to be technology-neutral, since inventions can be made using electronics, software, chemicals, biological molecules, natural and man-made materials, mechanical components, and more, individually and in combination, across all industries. A better mousetrap, an improved mechanical lock, a new cancer medication, a stronger cryptographic security system and an advanced process for genetic manipulation must all be assessable under the one law to determine whether they are ‘inventive’ or ‘obvious’.
Secondly, the law of inventive step is expected to be objective. Ideally, the answer to the question ‘is it obvious?’ is independent of the decision-maker and free from any subjective or value-based judgment.
Thirdly, inventive step is expected to satisfy policy objectives. Whether it is the US Constitutional purpose of ‘promot[ing] the progress of ... the useful arts’, or the (generally less-explicitly stated) economic rationale in Australia and other jurisdictions, inventive step is the ultimate gatekeeper of the patent system. After it has been established that an alleged invention lies in a field of patent-eligible subject matter, and is novel (i.e. not already known in the same form) determining whether it constitutes a sufficient advance to be worthy of a state-sanctioned exclusive property right is wholly the work of the law of inventive step.
This is important work. If the bar to be cleared by the inventor is set too low, then we may make the mistake of granting patents on trivial developments that are not worthy of protection, thereby preventing others from making use of technology that should be freely available. Conversely, if the bar is set too high we may fail to provide the necessary incentives for inventors, investors and industries to take risks in bringing new or improved products and services to market, building businesses, creating employment, and generating new economic activity and productivity improvements through technology.
And because it is so hard to satisfy all of these complex and challenging requirements, the law of inventive step has become very complex over the years, through the combined efforts of courts and legislators. One particular creation of the courts that has received much critical attention over the years is the notion that all that is needed to support the grant of a valid patent is a ‘scintilla of invention’. This sounds like it sets the bar pretty low. However, although the Australian courts seem determined to hang on to the ‘scintilla’, my view is that under the current law it actually has no bearing on what is required to establish an inventive step.
In a sense, then, the persistence of the anachronistic ‘scintilla of invention’ in the case law should be (mostly) harmless. However, so long as it continues to be cited by the courts, and raised by critics of the patent system as a significant issue, it is a distraction that gives rise to the risk that we will fail to recognise and address the real problems plaguing the law of inventive step in Australia.
