I don’t think any patents will hold it meaning in China at all. There are counterfeit brands (similar quality or cheap and ripoff quality) both. There are economy police forces that would go inspect and seize these counterfeit goods if your business is being sued for inspection. However, most of the time, these guys are bribed away and turning their eyes. The big guys in government will not care enough. Unless it is something that could stir a huge conflict against other countries such as military technologies and so on....I think even war planes and some are simply copy cat from the super power countries.
Here in the US, we are very strict and regulated on these issues, but many other countries beside China, they do appreciate (counterfeit goods) and will pay for it at cheaper price. However, there are some of these funky business as of late, had been infecting Amazon by a lot. Soon, Amazon will face a challenge.
A Smartphone company XiaoMi is basically a copy cat of Apple IPhone, the founder is billionaire and the company is healthy+strong over there. Then we have Huawaii which does similar things but on a much lesser scale and can export into the US...etc...etc..you get the idea. Taobao and Aliexpress is basically a copycat of Amazon but based off of counterfeit goods to the rest of the world and Chinese labor forces. Jack Ma is also made into a billionaire by...”copy cat”....there is no boundaries.
Just visit China and stroll around their markets, you will see huge differences in materials goods, patented and copy rights stuff, which hold no meaning over there.
one of the latest example of counterfeit goods is those Hollywood big hit movies. They got released 1 week in China before the US. Because in the past, the lesson learned is that the Americans rather enjoy new movies in theater, and they respect copy rights, together with punishments if infringement happened. However, when shown in the US first, the Chinese somehow grab the copy as soon as possible, and Official (or so they branded it) DVD/Blu-ray will be filling the street in China before the movies even hit theaters, which results in a huge losses.
