"A lot of web commentators really wanted this to be a Good v Evil showdown, with the sizeable backlog of uncertainties around Linux, Microsoft and patents settled in public. That hasn’t happened. There isn’t a consistent interpretation, either. Did Microsoft back down to avoid a courtroom test of the FAT long filename (LFN) patents? Did TomTom back down to avoid … being crushed like a bug? Did Microsoft win because they got the money (and dodged the countersuit)? Did TomTom win because they get to carry on using Linux (and recognition of their navigation patents)? Who can say?"
