Please do forgive my ignorance
what I understand so far is: Microsoft didn't pay to use the patent. Motorola can't get Microsoft's products banned because their patent is under FRAND. Microsoft can decide to now buy a license to those patents, but even if they don't, they don't have to worry about their products being banned which in turn weaken Motorola's negotiation ability.
I don't know if my understanding is correct or not, but what I am now wondering about is: how will this ruling affect future commitments by companies (not just Motorola) to putting their patents into standards? Does this ruling strengthen the value of those patents or does is weaken them? And does it mean that companies can put their products into the market before getting the license and only worry about the license when they get sued?
