"This is very typical to Chinese culture where being copied is a form of flattery. I had a similar experience when I launched my product i-gami in a Hong Kong trade show. A year later in a Dusseldorf how i saw my product in a Chinese booth with MY packaging pixel to pixel. The Only difference was that the name was changed from i-gami to O-gami. The astonishing thing was that the logo on the part itself, which was a styled "i" for the "i" in "i-gami", still remained on the knock-off part. "
