Apple has clashed with Valve over information requested for its antitrust lawsuit with Epic Games.
Apple is seeking sales information about Valve's gaming platform Steam, a fierce rival to the Epic Games Store in the PC gaming sector.
Valve says that the information requested is not readily available, and that does Apple need it for its case.
PC gaming giant Valve, owner and creator of the gaming platform Steam, has refused an Apple request to provide information related to sales and advertising revenue for use in its fight against Epic Games.
In a court submission, Apple and Valve submitted a joint letter stating that parties have been unable to reach an agreement over outstanding disputes relating to a subpoena served to Valve in November.
