These include a lawsuit that video game maker Epic Games Inc filed against Google last year, accusing it of having anticompetitive app store rules.
The lawsuit is expected to focus on Google's requirement that some apps use the company's payment tools to sell subscriptions and content and pay Google as much as 30% of sales, according to two sources.Google already faces a federal lawsuit brought by the Justice Department last year and related antitrust cases brought by two separate groups of attorneys general.
