The tech giant has argued that its Play store competes fiercely with Apple's App Store, and that Donato unfairly allowed Epic to tell jurors that Google and Apple are not competitors for app distribution and in-app payments.
Google also said in its appeal that Donato was wrong to issue an order affecting users and developers nationwide, not just Epic. It said the judge was acting as "a central planner responsible for product design."
Epic has asked the 9th Circuit to reject those arguments and accused Google of a "years-long strategy to suppress competition among app stores and payment solutions."
