What are the licensing methods of patent rights?

The types of patent licensing can be divided according to their nature, scope and authority. According to the nature of license, it can be divided into contract license, planned license and compulsory license. According to the rights and scope granted by Licensor to Licensee, it can be divided into: 1. Exclusive license means that the licensee not only has the right to exploit a patented technology within the specified time and territory, but also has the right to refuse any third party, including all others including the licensor, to exploit the technology within the specified time and territory. 2. Exclusive license is also called exclusive license, that is, in a certain area, the licensor only allows one licensee, and no longer permits others to exploit its patent in that area, but the licensor still has the right to exploit it in that area. That is to say, an exclusive license is basically the same as an exclusive license except that it cannot exclude the licensor's own implementation. 3. General license is also called non-exclusive license. It is a group of licensors, allowing the licensee to use a patent in a specified time and area, while the licensor still reserves the right to use the technology in the area and signs a license contract with a third party for the same technology. 4. Subordinate license is also called subordinate license. The licensee of this license may, with the consent of the licensor, license a third party to exploit its patent in its own name. The conditions of sub-licensing must be clearly stated in the licensing contract. If it is not stated, even an exclusive license cannot be considered as having a sub-license. 5. Cross licensing is also called reciprocal licensing, mutual licensing and interchange licensing. It refers to a transaction in which two or more patentees grant each other the right to exploit their respective patents under certain conditions. Cross-licensing generally does not involve the payment of royalties, but is limited to the scope and duration of exchange technology. If the two patents are not equal in value, one of them can also give the other a certain compensation.
