The types of patent licenses can be divided according to their nature, scope and authority. According to the nature of the license, it can be divided into contract license, planning license and compulsory license. According to the rights and scope granted by the licensor to the licensee, it can be divided into: What are the types of patent licenses? 1. Exclusive license means that the licensee not only obtains the right to implement a certain patented technology within a specified time and region , and has the right to refuse any third party, including all others including the licensor, from implementing the technology within the specified time and region. 2. Exclusive license is also called exclusive license, that is, in a certain region, the licensor only allows the licensee and no longer allows others to implement its patent in the region, but the licensor still has the right to implement it in the region. That is to say, an exclusive license is basically the same as an exclusive license except that it does not exclude the licensor from implementing it. 3. General license is also called non-exclusive license. The licensor allows the licensee to use a certain patent within a specified time and region. At the same time, the licensor retains the right to use the technology in the region and sign a licensing contract with a third party for the same technology. 4. Sub-license is also called sub-license. The licensee of such a license may, with the consent of the licensor, license a third party to implement its patent in its own name. The conditions for sublicensing must be stated in the license contract. If not stated, even if it is an exclusive license, it cannot be considered to have the right to sublicense. 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 implement their respective patents under certain conditions. Cross-licensing generally does not involve payment of royalties and is limited to the exchange of technology scope and term. If the value of two patents is not equal, one party can also give certain compensation to the other party.
