Opening the Distribution Side: Catalogs, Stores, and Safety
The distribution side of the Epic remedy concerns a specific problem: a rival app store can be technically available and still have no realistic chance to matter if it lacks both apps and users. The Ninth Circuit upheld two connected remedies for that problem—access to the Google Play catalog and a path for third-party stores to be distributed through Play. Understanding the difference between them makes it possible to judge what competition is actually being enabled, and why developer choice, security review, reasonable fees, and technical oversight remain part of the opening.
Catalog access tackles the supply problem
A new app store begins with a disadvantage that a normal product launch does not always face. Users may be willing to try a different interface, but they still expect the apps they already use. Developers may be willing to reach another audience, but they do not want to invest in a store that their users will not visit. The result is a familiar network-effect trap: no catalog means no users, and no users mean no developers.
The catalog-access provision addresses the first half of that trap. It requires Google to permit third-party Android app stores to access the Google Play catalog so that they can offer Play apps to their users. In practical terms, the remedy gives a rival store a chance to begin with a library comparable to the one that made Play attractive. It does not promise that the rival will acquire the same users, build the same reputation, or win developer loyalty. It changes the initial supply condition so that those competitive questions can be tested in the market rather than decided in advance by the catalog gap.
The court treated this as a response to network effects that Google had unfairly strengthened through anticompetitive conduct. The important causal claim was not that every app in Play was the product of unlawful conduct. It was that Google’s exclusionary behavior helped entrench the platform’s position and magnify the effects of the catalog and user base it had accumulated. Allowing rivals temporary access to that catalog was therefore a way to lower an entry barrier tied to the proven violation.
The remedy contains two qualifications that show what catalog access does not mean. First, the period is limited. The appellate opinion describes a three-year window intended to give rival stores a fair chance to get off the ground, not a permanent transfer of Google’s catalog ownership or business. A time limit also reflects the court’s remedial logic: the intervention is meant to counteract an entrenched advantage, not replace ordinary competition indefinitely.
Second, developers receive a mechanism to opt out of inclusion in catalog access for a particular third-party Android app store. That control matters because opening the distribution system does not require treating every store as an equally trusted destination for every developer’s work. The court considered intellectual-property interests, including the possibility that a developer might not want an app carried through a particular store.
