As far as the patent itself is concerned, the patent can be implemented, licensed, transferred, invested and financed, standardized, etc.
Almost means it involves buying and selling transactions. You should be talking about licensing, that is, if you pay me, I can license you to use it, but the patent right is still mine (similar in nature to renting). But the specific situation actually depends on the content of your negotiation and the purpose of the other party's use. If the other party thinks that your patent is good, it is used to implement (make things) or the other party has its own products but just doesn't want to be sued for infringement, that is license; If the other party wants to buy your patent (that is, the patent belongs to him), it is the transfer of ownership. Generally speaking, the transfer fee is higher than the license fee.
