Google isn't complaining about losing. It's complaining about the unfair way it believes the winners won.
How is it unfair?
Google believes that a cartel of competitors formed to combine resources with the main purpose of using those resources to bid on IP to use against Android. The winning bid didn't reflect any individual competitor's valuation of the asset, but rather the aggregate of their valuations given that they all plan to use the asset as leverage against Android. Google thinks this is anticompetitive.
