WASHINGTON DC: Microsoft Corp, Oracle Corp and other companies that have provided information to the US government for its antitrust lawsuit against Alphabet's Google were granted more time on Nov 11 to propose a protective order for their confidential data.

The group, which also includes AT&T Inc, Amazon.com, Comcast Corp, Duck Duck Go Inc, Sonos Inc, and T-Mobile US Inc, had told federal Judge Amit Mehta that they would not be able to make proposals by Nov 13 and had sought an extension until Nov 20. Mehta granted their request late Nov 11.

The US Justice Department sued Google on Oct 20, accusing the US$1 trillion company of illegally using its market muscle to hobble rivals, in the biggest challenge to the power and influence of Big Tech in decades.

Google has said it will fight the lawsuit.

The parties cooperating with the government said in a court filing that they gave the Justice Department investigators information, including business plans and strategies for competing with Google.

"One of the key issues here is the extent to which Google personnel will gain access (by virtue of being named a defendant in an antitrust lawsuit) to the non-parties' most sensitive confidential business documents," the companies said in a joint request filed with the court.

The companies said they wanted to have access to draft protective orders proposed by Google and the Justice Department, which are due Nov 13, before writing their own.
