I almost never advice people to look at stocks. I may have mentioned this one on this board some time ago. Take a look at VRNG, do your own DD. I'm holding a lot of it (both the stock and Jan. 2014 calls) and am convinced it will go a lot higher from where it is now. It's worth a small gamble at least IMHDO.
They both made me nervous, lol. I looked but seems and I could be wrong, that the real income comes from court action, or licensing, which may or may not materialize. If I had to pick between the two it would be actg.
