Epic has launched an appeal against last week’s ruling in its case against Apple’s App Store policies.
On Friday, the court issued a permanent injunction prohibiting Apple from preventing app developers from directing users to payment methods other than the App Store, which many regard as a defeat for Apple.
However, the court ruled against Epic on nine of ten issues and ordered the company to pay millions of dollars in costs.
Epic CEO Tim Sweeney stated that he is “as determined as ever to fight on.”
Epic had argued Apple’s tight control of its iOS platform amounted to a monopoly.
But the court found Epic had failed to prove its case.
“The court cannot ultimately conclude that Apple is a monopolist,” judge Yvonne Gonzalez-Rogers said.
Apple has characterised the decision as a clear victory, claiming that it is about communication between app developers and users.
However, the injunction allowing developers to link to their own purchasing mechanisms – the only part of the ruling that went against Apple – may result in fewer customers using Apple’s in-app payment systems, which take a 30% cut.
The court has granted Apple a 90-day reprieve before the ruling goes into effect, and the technology behemoth has yet to decide whether to appeal.
It’s also unclear whether any changes would be limited to the US market or implemented globally.

Following the decision, Mr Sweeney tweeted, “Today’s ruling isn’t a win for developers or consumers.” For a billion consumers, Epic is fighting for fair competition among in-app payment methods and app stores.”
Epic gave notice to appeal the judgement – “and all orders leading” to it – in a filing with a California district court on Sunday, but without much more detail.
A similar legal battle is ongoing between Epic and Google, which operates the equivalent Android app store.
