What are the contents of monopoly and patent?

Monopoly (usually translated as monopoly), individual capital, is generally divided into seller monopoly and buyer monopoly. Seller monopoly means that the only seller faces the competitive consumers in one or more markets through one or more stages; Buyer's monopoly is just the opposite. Monopolists can adjust prices and output according to their own interests and needs in the market.

Patent Literally, "patent" refers to exclusive interests and rights. The word "patent" comes from Latin "Litterae patentes", which means open letters or open documents. It is a certificate used by medieval monarchs to issue certain privileges, and later refers to the exclusive right certificate signed by the British king himself. Patents are the largest source of technical information in the world. According to empirical statistical analysis, patents contain 90%-95% of the global scientific and technological information.
