As one of the best performing tech stocks of 2012, Vringo (UNKNOWN:VRNG.DL) rose almost 250% for the year. Much of its meteoric rise was due to the storyline involving its major lawsuit against Google (NASDAQ:GOOGL) for copyright infringement on several of its mobile patents. The company has 31 patents and applications that are useful in the mobile market, which has the potential to generate a lot of revenue, and makes this a very exciting company just as mobile is exploding. However, as Motley Fool tech and telecom analyst Andrew Tonner tells us in this video, there is still a lot of uncertainty around Vringo.
