When you break this company down into what the current operating company is worth based on revenue and income. Then consider the cash on hand. Then consider the premium for the IP and ongoing work from the engineering team, it isn't that hard to come up with 5 Billion. Plus it must be kept in mind the current revenues are sort of an anomaly since we are in between licenses, and the revenues have dropped of as a result.
So if you can justify this company being worth 3 billion as an ongoing concern, that only leaves 2 Billion for the value of the IP.
I remain fairly confident we get a double on share price from here.
