The U.S. Department of Justice is considering asking a federal judge to break up Google after its ubiquitous search engine was declared an illegal monopoly, but it is just one of many possible remedies under review, according to a court filing.

In court papers filed late Tuesday, government lawyers outlined a series of potential remedies it may pursue, including restrictions on how Google’s artificial intelligence mines other websites to deliver search results, and blocking Google from paying companies like Apple billions of dollars annually to ensure that Google is the default search engine presented to consumers on gadgets like iPhones.
