The anti-trust case, which was about Apple’s use of its App store, was brought by "Fortnite" creator Epic Games.

Epic went to trial earlier this year over Apple's practice of forcing developers to use its in-app payment system and to pay commissions to the iPhone maker. In September, Judge Yvonne Gonzalez Rogers told Apple that it had to make changes to the app store because it was keeping consumers in the dark about alternative payment methods and ordered Apple to lift its ban on in-app links, buttons and messages to users about other ways to pay.

Apple has appealed the judge's ruling, asking her to pause her orders while the appeals process plays out, which could take several years while it continued to keep users in the dark, make money and squeeze out rivals.

Judge Rogers was furious and said that Apple's prohibitions on telling consumers about other payment methods showed "incipient antitrust conduct including supercompetitive commission rates resulting in extraordinarily high operating margins" for its App Store.

She wrote that Apple's own in-app payment methods would still be more convenient than third-party methods and that many consumers might still choose to use it.

"The fact remains: it should be their choice," Gonzalez Rogers wrote. "Consumer information, transparency, and consumer choice is in the interest of the public."

Apple said it will appeal Gonzalez Rogers' denial to the U.S. Ninth Circuit Court of Appeals, which could grant Apple a temporary stay before the 9 December deadline.

"Apple believes no additional business changes should be required to take effect until all appeals in this case are resolved. We intend to ask the Ninth Circuit for a stay based on these circumstances," Apple said in a statement.
