I don’t really understand the reason to even do such a thing. If it really is to “protect the IP against foreign powers” like they claim, what can even be done if the patent is violated? If China, Russia, or whoever the US’s villain of the day is, develops a similar advanced craft or weapon what are they going to do? I understand that they prosecute people for selling state secrets but they would never file copyright infringement or patent violations. Who would even uphold those punishments? I see this, and to some extent the AATIP videos, as a “Look what we’re working on” type of soft-declassification to puff out their chest to rival govts or even private defense contractors who keep an eye on news like this.
