In a significant decision on February 11, with implications for the patentability of artificial intelligence, the Emotional Perception AI Limited v Comptroller General of Patents, Designs and Trade Marks, unanimously allowed an appeal by Emotional Perception AI Ltd. The Court rejected the established four-step approach from the 2006 Aerotel case and aligned the United Kingdom with the jurisprudence of the European Patent Office (EPO). The judgment requires the UK Intellectual Property Office (UKIPO) to adopt a new framework for assessing such inventions and return the application to the UKIPO for reconsideration.
