I think things you mentioned, and all so-called "closing inventions" is the most strictly prohibited things to research, really. This taboo is the main reason there is no any real AI development, meanwhile. Real AI will inevitably will figure out a tons of such inventions, just by sorting out combinations of physical effects and phenomenons that was never studied by humans.
Also, it is impossible to keep any realised, working invention in secret long enough to gain any stable supremacy. As soon as it become known that something is possible, it is just a matter of time when it will be replicated. And in case of really important "closing inventions" nobody will give a fuck about IP rights or patents. That's the nature of science.
Even if TPTB dream to have some "superior technology", they could not afford it or allow its develoment even for themselves, as it will quickly bury them all.
