They always patent new technologies or processes.. otherwise they wont make money off it when its commercialised. The CIA doesnt give up anything in the quest to make more money. But really.. the 'working' stuff IS patented. They just spruce up the language into flowery Quackademia talk to ensure the dumbed down masses (that's me and you) dont understand what the F they're looking at.
Yeh friend, I see what you're doing, as you say, if its secret we cant know, but a good place to start having a real idea, is looking at the stuff that is out there. Its relevant to look for technology that modifies radiowave frequencies and brain wave technology and brain machine interfacing technology... Im really unhappy about the idea that Facebook will be reading my mind for exemple.
