Note...on Ring that was on its original market entry .They have since patented new devices developed and are in a patent infringement lawsuit currently with Skybell Technologies.I'm sure somewhere along the way there will be more lawsuits as the value of the QD market heats up.Thats why I like the patents QMC own are first adoptor and broad in scope.Some posters have said QMC picked up trash out of the waste basket with the Bayer patents because they got them do cheap.Gates and Jobs got cheap trash from Xerox as well ; )
