Patents are not commodities. Patent is a legal concept, which is usually the abbreviation of patent right. However, because patents can be licensed and transferred, they have certain commodity attributes.
"Patent" has two basic meanings, one is the exclusive right to use, and the other is the invention-creation or technical scheme itself that obtains the exclusive right to use.
Patent types include invention patent, utility model patent and appearance patent.
And commodity patent refers to the patent right of commodity.
