What are the ways of patent licensing?

Patent licensing includes the following ways: exclusive use license: that is, the licensor grants the licensee the exclusive right to use the licensed patented technology within the time limit, area or field stipulated in the licensing contract; 2. Exclusive exploitation license: that is, the licensor grants the licensee the right to exploit its patent under certain conditions, while the licensor reserves the right to exploit it by itself, but the licensor may not sublicense the patent to a third party; 3. General use license: that is, the licensor authorizes the licensee to manufacture, use or sell the licensed patented products or technologies within a specified period, region or industrial field. Article 45 of the Patent Law: Since the date when the patent administration department of the State Council announced the grant of the patent right, any unit or individual may request the Patent Reexamination Board to declare the patent right invalid if it considers that the grant of the patent right is not in conformity with the relevant provisions of this Law. Legal basis: Article 35 of the Patent Law of People's Republic of China (PRC). Within three years from the date of filing, the administrative department for patent in the State Council may, upon the request of the applicant at any time, make a substantive examination of the application. If the applicant fails to request substantive examination within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn. The patent administrative department of the State Council may, when it deems it necessary, examine the application for a patent for invention on its own.
