Patent transfer in my country usually has the following three forms: 1. Overall patent transfer, exclusive licensing, so-called transfer of patent ownership, and 10-year independent property rights. If the patentee (inventor) transfers the entire patent to a company, after both parties sign the transfer contract, the inventor (patentee) only retains the invention right. 2. Exclusive license for patent implementation means that a company buys out the patent. Only the patentee and the family business can use the technology, and the patent cannot be transferred to a third party again. 3. A general license for patent implementation means that the patentee authorizes a certain enterprise or individual to produce the patent. It can also authorize multiple enterprises or individuals.
