If only it was that simple. with all the cross license agreements and side contracts, well it's anything but easy to put together.
A good example would be MOT. They sell 2g. They sell 3G. We lost a court case with them 8 years ago. All the patents we have delevoped since that time apparently are worthless in regards to collecting from MOT. PRE 95 sure, post 95, where's the money. They're using it, are they not.
