Background
PhantomALERT offered a crowdsourced traffic-safety app through Apple’s App Store. After the COVID-19 outbreak, it revamped the app to include hotspot mapping and planned symptom, testing, vaccination, and contact-tracing features. Apple rejected the update under guidelines limiting COVID-19-related apps to recognized or credentialed entities. Apple later relaxed certain requirements for exposure-notification apps, but PhantomALERT alleged that it did not receive notice of the change.
PhantomALERT sued Apple under Sections 1 and 2 of the Sherman Act and California antitrust and unfair-competition law. It alleged that Apple unlawfully tied the iPhone to the App Store and monopolized markets for “access to apps on the iPhone” and “access to Covid-19-related tracing apps.” After PhantomALERT failed to oppose Apple’s dismissal motion and instead submitted an untimely amended complaint, the district court dismissed the original complaint without prejudice and denied leave to file the proposed amendment as futile.
The Court’s Holding
The D.C. Circuit first held that it had appellate jurisdiction. Although the district court dismissed the original complaint without prejudice, its order was final because it denied leave to file the proposed amended complaint, called the order final and appealable, and directed the clerk to close the case.
On the merits, the court held that the amended complaint failed to plausibly define the product markets required for PhantomALERT’s Sherman Act claims. The complaint did not allege facts addressing reasonable substitutes for the App Store, such as browser-based access, and therefore did not plausibly establish a single-brand aftermarket for “access to apps on the iPhone.” PhantomALERT’s alternative theory based on Apple’s power in the smartphone foremarket was forfeited because it had not been presented to the district court.
The proposed COVID-19-app submarket was also inadequately pleaded. The complaint inconsistently referred to a market for access to COVID-19 tracing apps and a market for the apps themselves, and its conclusory assertion that such apps were not substitutable for other apps did not plausibly establish either market. The court therefore affirmed the rejection of all three federal antitrust counts. PhantomALERT did not dispute that its Cartwright Act claim rose or fell with those counts and did not appeal dismissal of its California unfair-competition claim.
Key Takeaways
- An antitrust complaint must plausibly define a product market by addressing interchangeability and reasonable substitutes; labels and conclusory assertions are insufficient.
- A proposed single-brand aftermarket must be supported by allegations explaining why other means of obtaining the relevant functionality are not substitutes.
- A plaintiff generally cannot obtain reversal based on a market-definition theory that it failed to present to the district court.
- The judgment did not bar PhantomALERT from filing a separate action, subject to any other limitations, because the district court had not held that no conceivable amendment could cure the pleading defects.
Why It Matters
The decision underscores that challenges to closed digital ecosystems must plead the relevant market with economic substance. Allegations that users are confined to a platform’s proprietary app store do not alone establish that the store constitutes a distinct antitrust market.
The opinion also clarifies that a dismissal without prejudice may still be immediately appealable when the district court plainly intends to end the action, while distinguishing such finality from a dismissal with prejudice carrying potential claim-preclusion consequences.
