Cloned Slipperential?

[Krawlin]

Maybe this has been said already, I didn't feel like reading the entire thread, but what about just refusing to sell your products to anyone ordering from China or other outlying nations known for pulling this kind of thing and where it is difficult to take legal action against them? I mean, it's too late now as far as the slipperential goes, but just as a future precaution should you produce another really innovative part like that, just refuse to sell to them. I mean, how much money would you really lose from a move like that, compared to allowing shipment of items to China and outlying nations known for this activity and losing business to a copied item?
