Supreme Court decides that AI-based neural network is not excluded from patentability (Emotional Perception AI Ltd v Comptroller General of Patents, Designs and Trade Marks)
The Supreme Court has unanimously allowed the appeal by Emotional Perception AI Ltd against the Comptroller-General of Patents, Designs and Trade Marks, holding that the claimed artificial neural network (ANN) system is not excluded from patentability as a ‘program for a computer... as such’. The court concluded that although an ANN constitutes a computer program, the claims were not excluded because they involved the use of hardware and therefore possessed the requisite technical character. In doing so, the court departed from the long–standing Aerotel approach and endorsed the ‘any hardware’ approach developed by the European Patent Office (EPO). The case has been remitted to the UK Intellectual Property Office (UKIPO) to apply the newly adopted framework. The judgment marks a significant realignment of UK patent law with EPO jurisprudence in relation to computer-implemented inventions. As well as summarising the decision, this News Analysis contains commentary from Bruce C Dearling, an attorney at Hepworth Browne, on the implications of the judgement.
