Oct 7 (Reuters) - A U.S. judge on Monday ordered

Alphabet's Google to overhaul its mobile app business

to give Android users more options to download apps and to pay

for transactions within them, following a jury verdict last year

for "Fortnite" maker Epic Games.

The injunction by U.S. District Judge James Donato in San

Francisco outlined the changes Google must undertake to open up

its lucrative app store, Play, to greater competition, including

making Android apps available from rival sources.

Donato said at an earlier hearing that he would

establish a three-person compliance and technical committee to

implement and monitor the injunction.

Epic's lawsuit, filed in 2020, accused Google of

monopolizing how consumers access apps on Android devices and

how they pay for in-app transactions.

The Cary, North Carolina-based company persuaded a jury in

December 2023 that Google unlawfully stifled competition through

its controls over app distribution and payments, paving the way

for Donato's injunction.

Google had urged Donato to reject Epic's proposed reforms,

arguing they were costly, overly restrictive and could harm

consumer privacy and security. The judge mostly dismissed those

arguments during an August hearing.

"You're going to end up paying something to make the

world right after having been found to be a monopolist," he told

Google's lawyers.

In a separate antitrust case in Washington, U.S. District

Judge Amit Mehta on Aug. 5 ruled for the U.S. Justice Department

and said Google had illegally monopolized Web search, spending

billions to become the internet's default search engine.

Google also began a trial in September in Virginia federal

court in a Justice Department lawsuit over its dominance in the

market for advertising technology.

Google has denied the claims in all three cases.
