They would have to buy approximately 120 million shares on the open market, which would impact the share price significantly.

If the ultimate plan involved taking the company private, then to acquire the remaining shares, another 145 million, at an inflated share price, then the remaining infringement suits would have to be valued at a high enough amount to offset their investment.

At what price would all of the current shareholders sell? What would the total dollars be?

I see no real investment reason for considering taking the company private. I see the ultimate rewards in a growth in the share price and substantial capital gains resulting from share bought and sold.
