LONDON, Dec 11 (Reuters) - Google on Wednesday defeated

an attempt in a London court to revive a lawsuit brought by a

hospital patient on behalf of 1.6 million people over medical

records provided to the U.S. tech giant by a British hospital

trust.

The Royal Free London NHS Trust transferred patient data to

Google's artificial intelligence firm DeepMind Technologies in

2015 to help develop a mobile app to detect kidney injuries.

Britain's data protection watchdog, the Information

Commissioner's Office, said in 2017 that the Royal Free, which

is part of the public National Health Service (NHS), misused

patient data when it provided the information to DeepMind.

Google and DeepMind were sued in 2022 by Royal Free patient

Andrew Prismall on behalf of 1.6 million people for alleged

misuse of private information.

London's High Court threw out the lawsuit last year on the

grounds that there was no prospect of establishing that all 1.6

million claimants' private information was misused or that they

had any expectation of privacy in relation to the information.

Prismall sought to appeal that decision, but the Court of

Appeal dismissed his appeal on Wednesday. Prismall's lawyers

declined to comment. Google did not immediately respond to a

request for comment.
