(Reuters) - 

A ruling in the U.S. search antitrust case against Alphabet's Google on Tuesday is a win for mobile phone manufacturers including Apple and Samsung, who a judge said Google can keep paying  to be the default search engine on new devices.

Google has said it will file an appeal in the case, meaning the ruling is not likely to take effect immediately.

Here are some of the arguments Apple and others made in court papers ahead of the ruling:

APPLE

The iPhone maker supported requiring Google to share its search data with artificial intelligence competitors such as OpenAI, Anthropic, Perplexity, and said it plans to offer more AI-driven options in search.

Apple recently saw a decrease for the first time in the number of Google search queries coming from its Safari browser compared to a year prior, the company said in May.

"True competition in the market is not far away," Apple said.

But cutting off payments to Apple that have reached $20 billion annually would only enrich Google and cut into Apple's development budget, since there are no other good options to offer as the default, Apple argued.

SAMSUNG

The South Korean smartphone maker also opposed ending Google's payments - and prosecutors' bid to extend the prohibition to Google's AI app, Gemini. 

Stopping that funding would hurt Samsung's ability to compete with the more profitable Apple, which the Justice Department has separately accused of monopolizing U.S. smartphone markets, the company said. Such a move could even push Samsung to exit the U.S. mobile phone market, as Microsoft, Amazon and LG Corp have done over the past decade, it said.

The handset maker further argued that its most recent agreements with Google are not exclusive and do not hamper competition from AI competitors.

MOTOROLA

The Chicago-based cell phone maker is the third largest in the U.S. by a wide margin, and said that ending Google's revenue sharing payments would hurt it the most. Motorola argued that such a ban should only apply to companies with 30% or more of the U.S. market. That would capture Apple and possibly Samsung, which reached 31% of the U.S. market this year according to research firm Canalys.

MOZILLA

The non-profit Firefox developer sought an exception to any payment ban for independent browser makers, saying that while searches through its browser only account for a tiny sliver of Google queries, payments from Google comprise 85% of its annual revenue.

UNIONIZED GOOGLERS

Alphabet Workers Union-CWA, which represents around 1,000 workers at Google and its subcontractors, called for anti-retaliation provisions to help employees flag potential antitrust violations.
