Alphabet's Google on Friday appealed a federal judge's ruling in Washington that it holds illegal monopolies in online search and related advertising.

Here are some details:

• Google argued that U.S. Judge Amit Mehta made legal errors in his 2024 ruling, which ​found the company illegally blocked competitors by ​paying billions of dollars annually to firms ⁠, including Apple, to be the default search ​engine on new devices.
• The arrangements did not prevent ​device makers and browser developers from promoting rival search services, such as Microsoft's Bing, Google argued.
• The company said it ​fairly excelled in the market by developing a "superior search engine through hard work, bold innovation, and shrewd ‌business ⁠decisions."
• The U.S. Department of Justice is expected to file papers making its own arguments in July. A spokesperson for the DOJ declined to comment.
• Mehta had ordered Google to share some search data with competitors, potentially including artificial intelligence companies such as OpenAI, to restore competition. An ​appeals ⁠court ruling in Google's favour would overturn that order.
• If Google loses at the U.S. Court of ⁠Appeals ​for the District of Columbia ​Circuit, it could appeal to the U.S. Supreme Court.
