Patent Wars = Formlabs VS 3D Systems

personalfactory: I am really interested in ongoing argue between mentioned above companies about stereolitography patents. As we all know 3D Systems claim that Formlabs used couple of their patents concerning stereolitography technology. As you can see on 2 videos below none of them even mentioned about this issue in their interviews. Maybe it will be discussed later at the end of CES 2013… I want to believe in open-source stereolitography…
