Beefing up its docket for the fall term, the U.S. Supreme Court on Monday granted certiorari in five cases, including an antitrust class action dispute over Apple Inc.’s alleged monopoly over the market for iPhone apps.

In the case Apple v. Pepper, the court will consider Apple’s plea to end the class action, which could result in treble damages under the Clayton Act. The dispute turns on Apple’s “App store,” through which third-party software developers can sell software apps for the iPhone directly to consumers, in exchange for commissions paid to Apple.
