Google filed an appeal with the U.S. Court of Appeals for the D.C. Circuit. This action challenges a federal ruling that the company illegally monopolized online search and advertising markets.

The tech giant submitted a 111-page brief to the court. It argues the company succeeded through superior innovation and hard work rather than anticompetitive conduct.

Google disputes findings regarding multi-billion-dollar default search agreements with partners such as Apple. The company maintains these deals did not block rivals from competing.

The appeal also seeks to overturn a court order requiring Google to share proprietary search data and index details. This mandate includes sharing information with generative artificial intelligence competitors like OpenAI.
