With much of the world in lockdown, and politicians (and others) claiming that they must rely on the common sense (or intelligence) of the public to ensure that we emerge from the current restrictions with some economy remaining, I thought I would look this month at three patent law decisions – one from the UK Intellectual Property office, one from the European Patent Office and one from the United States Patent and Trademark Office (USPTO), all dealing with the same issue – an invention purportedly made by an Artificial Intelligence (AI) machine (DABUS) and all reaching broadly similar conclusions.
