Cue the legalese mantra - "We will vigorously defend etc., etc., harrumph, blah blah blah ... egregious violations of our IP, gollum, gollum."
I would love to read follow-ups to these and see if any of these companies have their own IP patents that answer to St. Clair's patents. Companies like them, that exist only to buy and hold IP, have destroyed the concept of shared IP. The only way they can make money is to negotiate deals or to sue. I suspect that their asking prices in negotiation are outrageous, ensuring that they get to sue later - but that's just my opinion.
I understand that they just want to make a living like all of us, but you can't tell me that you wouldn't make a decent living if you received one or two cents for every IP patent you hold charged on every cell phone made. iOS and Android phones saw around 6.8 million activations on Christmas day. At two cents per IP patent above, that one day would have netted $816,000.00. Charge three cents per IP patent and you make over 1 million for that day. Five cents, anyone? Yes, there is a way to make money and work together.
