What are the general ways of patent licensing?

1. Exclusive license is one of the ways of patent license, which means that the licensor grants the licensee the exclusive right to exploit the licensed patent within the time limit, area or field specified in the license contract. The licensor may not license the same content of the patent to a third party, and the licensor himself may not exploit the patent within the above time limit, area or field. 2. Exclusive license An exclusive license, also known as an exclusive license, means that the licensor grants the licensee the right to exploit its patent under certain conditions, and at the same time guarantees that it will no longer license a third party to exploit the patent within the above-mentioned license scope, but the licensor still reserves the right to exploit the patent by itself. Three. General exploitation license A general exploitation license means that the licensor grants the licensee the right to exploit the patent within the time limit, region or field specified in the license contract, but the licensor can still exploit the patent within the above-mentioned scope and can continue to license a third party to exploit the patent within the above-mentioned scope. Four. Cross-licensing Cross-licensing, also known as reciprocal licensing and mutual licensing, means that two or more patentees grant each other the right to exploit their respective patents under certain conditions, that is, one party grants the other party the right to exploit its patents at the same time or after accepting the other party's license. V. Sub-licensing Sub-licensing, also known as sub-licensing and sub-licensing, means that the licensee of the original patent licensing contract sublicenses the same licensed content to a third party under certain conditions with the prior consent of the licensor. In patent licensing, "technical secrets" are usually involved. According to the requirements of the patent law, the patent specification should give a clear and complete description of the invention or utility model, so that the technical personnel in the technical field can implement the invention or utility model. However, the patent law does not require the patent specification to disclose all the embodiments of the invention or utility model, and the patentee may take some of the best embodiments as technical secrets without writing them into the patent specification. In addition, in the process of patent technology implementation, some expertise and technical information obtained through long-term experiments of inventions or utility models may be involved.
