The article mentioned a handful of startups but there is no mention of any of these startups actually producing a product that people can buy. If you actually could buy a product or service from an Intellectual Ventures backed company this would be a powerful affirmation that IV is a real contributor and not just a troll.
That this PR piece makes no mention of such a product, making it very clear this has not happened. I expect this will never happened. IV startups are not meant to produce and sell product. They are meant to be bought out and bought out for a much larger sum than IV could get from just licensing the IP.
Now, there is nothing wrong with a startup selling out before it can bring it's product to market but it is a little bit dishonest to plan it that way.
Which, I suppose is an improvement over IV's normal policy of simply sitting on technology until a practicing entity re-invents it and then suing them. Still, it is a long way from showing that the world is better with Intellectual Ventures than without them.
