The Japanese could make the claim that when their car manufacturers were beating the crap out of GM, Ford and Chrysler, US manufacturers stole (i.e. copied) their IP to catch up. Some call it IP theft, others call it knowledge transfer. I guess it never occured to Toyota to get kanban and JIT patented. Right now you have Apple suing Samsung over copying the shape of icons on a display - totally pathetic. I think quick and widespread dissemination of innovation is a good thing. If you don't like getting copied, stay out of China.
Lol,
I guess you are not aware of how much western technology is in japanese vehicles ....
