I dont think cubers care about knockoffs anymore. Cube manufacturing companies are all chinese and patent laws are obscure a they dont even bother. Cubers will buy whichever cube is cheaper if 2 or more are exact copies (qiyi vs newisland)
Actually, Chinese patent laws are pretty comprehensive and well praised it's just that the patent has to be registered in China so while cubers may not care, the other companies might if they hold patents. The fact that most companies in the west don't understand this means they don't register the patent in China meaning all sorts of cheap knockoff replicas can be made.
