Judging from the development of the world, patents, as a kind of intellectual property, can be traded by their very nature.
However, China has not developed in accordance with the rules of the market, but in the direction of most interests. Therefore, the future of the patent trading industry is not as prosperous as its demand. China's innovation, intellectual property and other industries are all dancing with shackles. It is very contradictory for the rulers to want you to work in a disciplined manner and also want you to create more value through innovation.
These are all sad words, I don’t know if I can help you.
