The UK Supreme Court has upheld earlier decisions in rejecting a bid to allow an artificial intelligence to be named as an inventor in a patent application.
Technologist Dr Stephen Thaler had sought to have his AI, called Dabus, recognised as the inventor of a food container and a flashing light beacon.
But in 2019, the intellectual property office (IPO) rejected this, saying only a person could be named as an inventor.
The decision was then backed by both the High Court and Court of Appeal.
The IPO has argued, and courts have supported the view, that only “persons” can have patent rights, not AIs.
Now five Supreme Court judges have dismissed a bid to reverse those decisions, concluding that “an inventor must be a person”, and that an AI cannot be named as an inventor to secure patent rights.
The judgement does not deal with the issue of whether Dabus did in fact invent the food container and light.
But it added that “the government will nevertheless keep this area of law under review to ensure that the UK patent system supports AI innovation and the use of AI in the UK”.
Dr Thaler also argued that he was entitled to patents for Dabus inventions as the AI’s owner, but this was rejected.
A different decision could have caused “headaches for companies using [AI] software to innovate as they may not be the owner of the patent”, Diego Black, from European intellectual property firm Withers and Rogers, told the BBC.
Simon Barker, of law firm Freeths, said the judgement raised “interesting policy questions” about how governments might look to change laws in the future as AI advances.
Some legal experts expect pressure for changes to existing laws to grow, as AIs become increasingly capable of autonomously generating novel ideas.
In its statement, the IPO said it recognised “that there are legitimate questions as to how the patent system and indeed intellectual property more broadly should handle [AI] creations”.
In June 2022, the UK government published a response to its consultation on AI and intellectual property.
