To recap, Ironburg warned Valve of Valve’s patent infringement all the way back in 2014. The company dismissed the claims with the simple argument that its Steam controller and the plaintiff’s patent did not look alike. SCUF was granted the patent just a year before.
While Valve may have lost the case, US$4 million is probably like a drop in the ocean to the company. It remains to be seen if it will have to pay SCUF more than that amount. But of course, the company will likely appeal the decision before it comes to that.
