Technology giant Apple is facing a trial that threatens to upend its iron control over its App Store, which brings in billions of dollars each year while feeding more than 1.6 billion iPhones, iPads and other devices.
The federal court case in the US is being brought by Epic Games, maker of the popular video game Fortnite.
Epic wants to topple the so-called “walled garden” of the App Store, which Apple started building 13 years ago as part of a strategy masterminded by co-founder Steve Jobs.
Apple, which takes a commission of 15% to 30% on purchases made within apps, including everything from digital items in games to subscriptions, denies Epic’s claims.
Apple’s highly successful formula has helped turn the iPhone maker into one of the world’s most profitable companies, one with a market value that now tops 2.2 trillion dollars (£1.6 trillion).
Privately held Epic is puny by comparison, with an estimated market value of 30 billion dollars (£21.7 billion).
Its aspirations to get bigger hinge in part on its plan to offer an alternative app store on the iPhone.
Epic then sued Apple, prompting a courtroom drama that could shed new light on Apple’s management of its App Store.
Both Apple chief executive Tim Cook and Epic chief executive Tim Sweeney will give evidence in a federal courtroom in Oakland, California, that will be set up to allow for social distancing and will require masks at all times.
Neither side wanted a jury trial, leaving the decision to US District Judge Yvonne Gonzalez Rogers, who already seems to know her ruling will probably be appealed against, given the stakes in the case.
Much of the evidence will revolve around arcane but crucial arguments about market definitions.
Apple claims it faces significant competition from various alternatives to video games on iPhones.
For instance, it points out that about two billion other smartphones do not run iPhone software or work with its App Store – primarily those relying on Google’s Android system.
Epic has filed a separate case against Google, accusing it of illegally gouging apps through its own app store for Android devices.
Apple will also depict Epic as a desperate company hungry for sources of revenue beyond the aging Fortnite.
It claims Epic merely wants to freeload off an iPhone ecosystem in which Apple has invested more than 100 billion dollars (£72 billion) over the past 15 years.
Apple disputes those estimates, although it has not publicly disclosed its own figures.
Instead, it has emphasised that it does not collect a cent from 85% of the apps in its store.
The commissions it pockets, Apple says, are a reasonable way for the company to recoup its investment while financing an app review process it calls essential to preserving the security of apps and their users.
About 40% of the roughly 100,000 apps submitted for review each week are rejected for some sort of problem, according to Kyle Andeer, Apple’s chief compliance officer.
Epic will try to prove that Apple uses the security issue to disguise its true motivation – maintaining a monopoly that wrings more profits from app makers who cannot afford not to be available on the iPhone.
But the smaller company may face an uphill battle.
Last autumn, the judge expressed some scepticism in court before denying Epic’s request to reinstate Fortnite on Apple’s App Store pending the outcome of the trial.
At that time, Judge Gonzalez Rogers asserted that Epic’s claims were “at the frontier edges of antitrust law”.
The trial is expected to last most of May, with a decision to come in the ensuing weeks.
