In the 70s, the oil companies were allegedly buying patents for 100mpg carburetors and locking them up so nobody could use them. I asked my dad (Air Force) about that, and he laughed. He said the military could desperately use such technology, as supplying fuel to the military machines was a terrible logistical problem. The military would never, ever let lil' ole' patent law get in the way of that.

I have no idea what you're trying to communicate. I reread your comment three times and I am still unsure.

It's a historical example of a fake patent moat.

And how is it evidence in this case?
