What are the types of patent licenses?

The common types of patent license are exclusive license, exclusive license and general license. Now they are introduced as follows: 1. Exclusive license. Exclusive license means that the licensor completely grants the licensee the right to exploit the patent within the specified time limit and territory. In the case of exclusive license, the patent right of the patent that is allowed to be exclusively exploited still belongs to the patentee, but only the licensee has the right to exploit a specific patent within the specified period and within the specified area, and no one else, including the patentee, has the right to exploit the same patented technology. 2. Exclusive license. It means that in a certain area, the licensee enjoys the exclusive right to exploit the licensed patent within the validity period of the contract, and the patentee shall not allow any third party to exploit the same patent in the same area and at the same time. Different from exclusive license, in the case of exclusive license, the patentee has the right to exploit the patent in this area. 3. General permission. General license means that the licensor gives the licensee the right to exploit the patent in a specific area and time. The license is not exclusive and exclusive. The patentee may exploit the patented technology with the licensor and the third party, or may exploit the patented technology by himself.
