Carbon felt patent

As an industry leader and industry standard setter of integrated ceiling, I want to say two words: this far-infrared integrated Yuba technology is immature. Our company has been making yuba 17 years. No one can surpass it in research and development ability and technology. Why don't we make this one? Aren't we capable? No, based on the idea of thinking for consumers, we will never throw the garbage product such as electric heating tube into the market. In fact, there are many manufacturers in Zhejiang who produce this kind of all-in-one far infrared ray, all of which are workshops with miscellaneous brands, copying and imitating each other, and there is no exclusive patent! They all say their own is an exclusive patent! The cost is around 200 yuan, so it is called a patented product? I want to ask these profiteers, do you live up to your conscience?
