The U.S. Department of Justice is considering asking a federal judge to force Google to sell parts of its business in order to eliminate its online search monopoly. In a late court filing on Tuesday, federal prosecutors also said the judge could ask the court to open the underlying data Google uses to power its ubiquitous search engine and artificial intelligence products to competitors. A federal judge ruled in August that Google’s search engine has been illegally exploiting its dominance to squash competition and stifle innovation. Google plans to appeal but must wait until the remedies are decided.
