Revenue from these settlements probably won't look like much until a large number of them start generating an appreciable amount in total. If the market knew what the numbers were and when the company could expect to start receiving it, then it could buy the stock on the basis of that forecast. As it stands now, the market has nothing of substance to work with.
As an example, we are told that we have a settlement with Google. Our initial response is Wow. However, although it appears to be a windfall, the investing public hasn't the slightest idea what that entails. It could result in a lump sum payment, millions of $$$ every year or an agreement to buy Fred's coffee each mornig.
We has better get used to the fact that were not going to be millionaires in the near future.....if ever.
