Patent troll surviving on dilution until they get a payment from Apple as far as I can tell. Although, when your target has over $100 billion in cash, and your market cap is $200 million, that could be a pretty effective business plan as long as you have some good patent lawyers. Betting that the huge runup will eventually subside. Negative cash flow, so unless they have another patent being infringed, it has to come back to earth eventually.

They are suing Apple for patent infringement and the court has ruled in their favor. The settlement should be about double the whole market cap of the company. Apple continues to use a part covered by their patent in their phones.
