Now this could just be me being my cynical self, but I wonder how long ago Smart Patents decided to go ahead with all this getting rid of the competition?
Could it be they decided to take this action during the development of the "open-AND-closed" bolt shocker - they realised that the thing just plain blows, and decided the only way to sell them would be if the other markers in the world either didnt exist, or had to absorb such a high amount in license fees that they'd be overly expensive to be seen as competition?
Here's me hoping for SP to go out of business - tricks like this only serve to hold back development of our sport/hobby/activity.
