May 22 (Reuters) - Alphabet's Google on Friday appealed

a Washington federal judge's ruling 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 ( AAPL ) to be the default search engine on new

devices.

* The arrangements did not prevent the device makers and

browser developers from promoting rival search services like

Microsoft's ( MSFT ) Bing, Google argued.

* The company said it excelled in the market fairly 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.
