Following more than three months of deliberation, the verdict in the long-running Apple/Epic Games legal dispute was finally handed down a few days ago - and Apple considered itself to have won a resounding victory. Epic won on one point (Apple is not allowed to prevent developers from telling users that there are other ways to buy content for apps) but was clearly unhappy with the overall result.

Now Epic has filed an appeal (document uploaded by The Verge), which is not unexpected: immediately after the ruling was announced, CEO Tim Sweeney said the company would fight on.

"Notice is hereby given," the document reads, "that Epic Games, Inc, Plaintiff and Counter-Defendant in the above-named case, appeals to the United States Court of Appeals for the Ninth Circuit from the final Judgment entered on September 10, 2021 (ECF No. 814), and all orders leading to or producing that judgment."

Epic's lawyers haven't gone into detail concerning the grounds on which the company is challenging the ruling, but The Verge suggests that it probably involves allegations of violating federal antitrust laws.

Judge Yvonne Gonzales Rogers pointed out in the ruling that while there is evidence that Apple is at least approaching a monopoly-like position, Epic failed to prove it beyond a reasonable doubt, mainly because it didn't focus on this in its arguments.

The announcement of Epic's appeal, while unsurprising, will nevertheless come as bad news to Apple, which would dearly love the current wave of legal and ethical challenges to the App Store to end. But the firm's opponents will take heart from the progress they have already made; despite an apparent loss, Epic did extract one concession from Apple. As we've written elsewhere, the App Store is under pressure and Apple is cracking.
