Google has requested the US Appeals Court to overturn a lower court's ruling on Epic Games' antitrust lawsuit, which would force Google to allow third-party app stores and payment solutions to operate through its Play Store app marketplace.

In August 2020, Epic sued both Apple and Google, accusing them of unfairly restricting apps in their app stores to only use their payment systems (taking a 30% commission from all purchases) and blocking apps from using external systems.

The lower court's ruling would open Google's app store and apps to other payment systems, including those that support encryption.

However, in a 110-page document submitted to the Ninth Circuit Appeals Court on November 27th, Google argued that the California federal court judge's ruling "will directly undermine Google's efforts to compete with Apple and the iPhone."
