Funny thing is that EJ has actually talked about going after clones in court just last week according to one of their reps. I doubt they get any result though. China reproduces everything no matter what it is, and nobody can really enforce what is going on since it happens in China. They can stop them from shipping to the USA, but I have seen PING golf club knockoffs that look EXACTLY the same at 1/2 the price. Not sure of the quality, or if they play the same as original PING irons, but they are out there and people buy them.
The problem here is that everybody wants all of these items, and they continue to support the black market by actually buying them instead of buying from the original makers of these products. Money talks, and people would rather buy cheap **** than buy quality, and before you say, "That's just not true," just look at Walmart as a great example. Why would you buy from an American grocer when you can buy the same items form Walmart at 1/2 the price because it is produced in China by factories that pay 17 cents an hour and no bathroom breaks for 12 hour days? Because it is cheaper. Not saying that this right, but it is what it is. I won't set foot in Walmart myself. They actually use the government to subsidize their heath care plans.
