"Patent" refers to "patent right", which is a right enjoyed by inventors over their inventions.
Patents are not commodities. Patents are a legal concept and are generally the abbreviation of patent rights. However, since patents can be licensed and transferred, they have certain commodity attributes.
"Patent" has two basic meanings, one is the exclusive right to implement, and the other is the invention or technical solution itself that has obtained the exclusive right to implement.
Patent types include invention patents, utility model patents, and appearance patents.
