Where's the confusion?
China and its companies do not fall under the laws of the rest of the world. So there are no copyright or patent infringements within China.
For example, Joytech makes the Ego Twist, and although the "Twist" name may have a legal patent, the knockoff companies don't recognize it and make a knockoff Twist called just a "Twist". If you want an authentic Twist, you better make sure its actually made by Joyetch. This is why there are so many poor quality "Twists" or generic clones on the market.
All of these new companies (AWT, Basen, Cloud Chaser, EFAN, Imren, MXJO, and Vappower brands) producing batteries is amusing. It is extremely difficult to break into the battery industry because these manufacturing plants are in the multi millions of dollars. So how do most of them do it? They buy the second and third tier cells from LG, Panasonic, Samsung, and Sony (lesser quality batteries from the main battery manufacturers). They they re-wrap/re-brand these cells with their own logo, and then market them with misleading and over-rated specifications to make consumers believe these batteries are somehow better.
Sad part of all of this is they can get away with these tactics. There are no consumer advocate agencies (ie Consumer Reports) or policing agencies (Underwriters Laboratories) which hold any weight in China. The Chinese government doesn't care, because they are only interested in bringing in wealth into their country.
What don't you understand?
