AI cannot be patent 'inventor', UK Supreme Court rules in landmark case

Judge David Kitchin, announcing the court’s ruling, said that under UK patent law "an inventor must be a natural person".

An American computer scientist on Wednesday lost his bid to register patents over inventions created by his artificial intelligence system, in a landmark case in Britain about whether AI can own patent rights.

Stephen Thaler wanted to be granted two patents in the UK over inventions he says were devised by his "creativity machine" called DABUS.

His attempt to register the patents was refused by Britain’s Intellectual Property Office on the grounds that the inventor must be a human or a company, rather than a machine.

Thaler appealed to the UK’s Supreme Court, which on Wednesday unanimously rejected his appeal.

Judge David Kitchin, announcing the court’s ruling, said that under UK patent law "an inventor must be a natural person".

Thaler earlier this year lost a similar bid in the United States, when the Supreme Court there declined to hear a challenge to the U.S. Patent and Trademark Office’s refusal to issue patents for inventions created by his AI system.
