They did not "win" the case, it was settled by the two parties and that is a very important distinction. Defendants that "settle" a case do not admit guilt or any wrongdoing (infringing on a patent in this case). Instead, the parties come to an agreement that is mutually beneficial to both parties. Because the case was not litigated "on the merits" and heard by a jury or judge, no precedent has been set with regard to the validity of the patents.
Look, I'm not trying to cause waves here, I merely stating what I know based on my own knowledge and education. With that said, I DO think the settlement with Alarm Force is a step in the right direction, but it is by no means the end all be all. Trust me, I know lawyers, and after reading the Motion to Dismiss filed by Margaret Thies and the SCOTUS case she cited, it's unfortunately not going to be a slam dunk. I am, however, hoping for the best.
