A federal appeals court affirmed a lower court's decision to dismiss a lawsuit that accused Google of unlawfully dominating the GPS navigation market. The ruling, from the US Court of Appeals for the Ninth Circuit, found that the plaintiffs, including digital advertising business Dream Big Media, did not plausibly allege violations of antitrust law. The lawsuit claimed that companies were forced to purchase Google's Places API after buying other Google APIs for displaying maps on their websites, even if they preferred competing products. The court's decision effectively ends this particular legal challenge against the tech giant's practices in the navigation and mapping services sector.
