With a market cap of less than $350 million, shouldn't Google just buy them? I realize that they'd pay more than that, and that there might not be enough stock available to get a controlling share, but it would be an interesting strategy if they could pull it off.
It's about $425m as I write this. Yes, Google should probably try to buy them if they can. The people that control VRNG might consider that they'd rather have a billion in cash from the payouts, that they can then push into more patent gains, than to sell right now for, say, $800m.
I think people in that type of position frequently tend to get over-confident after winning, and rather than take one big payday, they keep rolling the dice.
