May 9 (Reuters) - The U.S. Department of Justice's

proposals in an antitrust case against Alphabet's Google

risk chilling artificial intelligence investments, AI

startup and Google partner Anthropic said in a court filing on

Friday.

Part of the proposal that would require Google to give the

DOJ advance notice of its proposed AI investments and

partnerships "would harm, not benefit, AI competition," the

company said in court papers filed in Washington.

The judge overseeing the case is considering what

measures Google should be required to take to restore

competition in the market for online search engines.

The DOJ and state attorneys general have expressed

concerns that Google could

extend its dominance to AI
