The suit involved the use of a lens to flatten the image throughout the magnification range. It wasn't S&B, it was Swaro and they lost in a European court. I spoke with ILya about it and he said that the suit was frivolous as they (Swaro) never should have been able to bring something like that to court. Swaro somehow got a patent on the design feature and they never should have been granted the patent in the first place.
