Making,
Comps are not trading at 20x, I can't see us trading at that value given one win, even if sizable.
Secondly, you ignored taxes, cut to nokia etc. 400 at 20x would actually be around $44 after considering those issues.
However, as I have said, I believe a more realistic multiple would be 3-5x off the first win. If able to then start licensing others without costly litigation as a result, the multiple should start to trend closer to its peer median of around 10x over time.
