I'm not really concerned about my ideas. I'm concerned about someone taking advantage of all my time and effort validating a potential market with an mvp, then swooping in with a slight tweak and crushing me with a new viewpoint and excellent, well funded execution.

I think that's just plain market competition :)

I'd like some way to say ..."hey...I'm going to try something out....I'd like for nobody on the planet to compete for at least 5 years while I give it my best. After that feel free, but in the meantime leave the potential market all to me."

I think that's how some people expect to (ab)use the patent system to their advantage.
