Google went to appeals court Monday in an attempt to convince a three-judge panel to overturn a jury's verdict declaring its app store for Android smartphones as an illegal monopoly and block the penalties imposed by a federal judge to stop the misbehavior.

Epic accused Google in a 2020 lawsuit of monopolizing how consumers access apps on Android devices and how they pay for transactions within apps.

A court ruled Google an illegal monopoly and mandated changes to its app store practices, including allowing third-party stores and alternative payment systems. These changes were set to take effect in November 2024.
