As i see it, all the US patent system is invalid with this kind of revelation. They can not claim any original idea any more, because of spying
Nothing in any of the snowden reports even hints at this - so I think your comment that "no patents have original ideas any more because of spying" is a little out there.
GP's comment is still far fetched. But US does indeed contemplate on starting economic espionage if they ever lose their tech lead.
