With patent pending, no.
I think all you're doing is indicating to the market that you have something playing in that area, and what it does, basically, is it gets your competitors to pay attention to it. They want to make sure that if I'm building something that is pretty much the same as you, but you're ahead in the process.... For example, I may end up having to pay you royalties when you eventually get your patent. As a competing business man, I should be aware of those situations because it may cost me tomorrow.
A patent pending is not a protection in itself.
