You are asking the wrong questions.?man said:...but China thinks they can get away with it.
Do they just have no morals or decency(or law)? ...
EVERYONE so far has missed something huge, monumental, just plain "can't see the forest thru the trees" reason why there is this perceived problem of copying designs.
I know exactly why it happens. I would venture to say that most individuals who have done SERIOUS trade with China also, at some point, had the lightbulb go on in thier head as to why.
I won't say the answer - It sounds bad - but I will say, without reservation, that it has nothing to do with money, morals, decency, or sense of fairness. I will also go even further by stating (my opinion only) that the average person in China just doesn't get what the big problem is, no matter how much we express our concerns.
Know why they copy stuff yet? Here is another hint...
In the US, if a consumer needs a 350 cubic inch engine, they have exactly one brand they can buy - A GM/Chevy 350. Each manufacturer has thier own design. In China, I have the choice of maybe 4 designs for a good 6-cyl diesel, one being a R6105 model. Where do I go in China to to get that engine? Any one of maybe 500 companies that manufacture the exact same engine, using the exact same model number.
Korea / Japan have an enormously huge, forest-thru-the-trees difference with China. Guess what that is, and the light will go on over your head, too.
