Apple Inc has asked appellate judges to throw out Epic Games’ bid to overturn a lower-court ruling that vindicated the iPhone maker and its App Store polices from breaking U.S antitrust laws.
Apple said Epic Games had failed to show any legal error that would justify the appeal.
Epic, known for its “Fortnite” game, largely lost a trial last year over whether Apple’s payment rules for apps were anticompetitive.
That decision found Apple had suitable reasons to force some app makers such as Epic to use its payment system and take commissions of 15% to 30% on their sales.
Following the ruling, Epic appealed in the 9th U.S. Circuit Court of Appeals.
Apple in its reply said Epic had failed to propose a reasonable alternative to the App Store policies.
In support of Epic’s appeal, attorneys general for 34 U.S. states and the District of Columbia said in January that Apple is stifling competition through its mobile app store.
Outside arguments in support of Apple are due next Thursday.
