Allow me to add...
They DO have products, the patents, if you want to call something you can't sell, a "product"...
And they DO have revenue...from selling the only product they ever could...stock shares..
All they had to do was make the decision to become the world class patent troll that they aspire to be but haven't even been able to consummate that task. Then, by default, the patents became THE FRONT (because they are worthless) that drives the sales of shares...fiat printed & sold shares.
So that is their product & that is their revenue...fiat printed & sold cheapo shares.
