Wolfire's antitrust lawsuit against Steam giant Valve has been dismissed.

In a filing, Judge John C. Coughenour of the US District Court Western District of Washington at Seattle said that Wolfire had failed to argue that Steam represents a monopoly within the games market. The developer's issue was largely with the 30 per cent cut that Valve takes from sales on Steam.

The judge says that some of Valve's competitors had taken smaller revenue shares yet have still failed, which in his mind indicates that the slice that Steam takes from sales is "commensurate" with the platform's value to consumers.

Coughenour also says that Wolfire failed to properly articulate how the antitrust element of its complaint against Valve, saying that Steam hasn't had a negative impact on the games market. The judge points to numerous releases coming out that are of a high quality.

While this case has been dismissed, it has been done so without prejudice, meaning that Wolfire can submit another complaint within 30 days.

The lawsuit was filed in April of this year, with Valve filing a motion to dismiss the following August.
