I'm not allowed to talk about this kickass technology my company is using, not even to dispute a patent claim my competitor is making.
I'm not allowed to post a question on this site because I can't talk about the technology my company is using.
I'm not allowed to post prior art on this patent because it might reveal how my company is solving problem x, a problem plaguing most of my competition and were they to figure it out, I'd lose some edge in my market.
