It feels more like an arms-race to me. Where I work we patent stuff for defensive purposes only, so we have something when we get sued (and we have been). Maybe that's just another boogieman, but it seems unless everybody stops nobody can.
China has basically no domestic patent litigation. The way you stop the litigation is to just remove the legal rights associated with patents. Let everything become a free for all. China is just lapping everyone else right now. The lack of strong IP rights is not hurting them. Companies over there are not suffering due to not being able to invest in technology. They invest despite not having strong IP protections. Not because they have strong IP protections. And they know they can't get a monopoly with a piece of paperwork ... a patent. So they continue to innovate at a breakneck pace just to stay ahead of everyone else.
America needs to learn how to evolve our system of industrial production. Our society of lawyers and paperpushers is going to get annihilated in the next ten years at this rate.
If it's really for defense you don't have to go to the expense of patenting stuff, disclosure is enough. IBM used to publish Technical Disclosure Bulletins (TDB) - I assume for patent defence.
