Apple has failed to persuade a U.S. appeals court to pause key parts of a federal judge's order requiring the iPhone maker to immediately open its lucrative App Store to more competition.

In April, a federal judge demanded that Apple begin allowing web links, cease restricting how links are formatted, and enable developers to offer external payment options without giving the company a cut of their revenue. Apple promptly appealed and requested that the order be put on hold until the legal proceedings were finished.

Apple Inc. lost its request to pause a court order requiring it to let App Store developers steer users to the web to purchase in-app items without paying a commission.
