SAN RAMON, Calif. (AP) — On Monday, Apple faces one of its most serious legal threats in recent years: 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 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.
