According to the provisions of the "Patent Law of the People's Republic of China" and the "Implementation Rules of the Patent Law of the People's Republic of China", patent rights can be licensed for implementation, and patent rights can be divided into the following types:
1. Exclusive license.
It means that only the licensee is allowed to implement the patented technology within the time and area agreed in the contract, and no one else may exercise the patented technology. In this case, the patentee also loses the right to use his patented technology within the prescribed time and area.
2. Exclusive permission.
It means that only the patentee and the permitted user have the right to use the patent within the time and area agreed in the contract between the right holder and the permitted user, and no one else has the right to use the patent.
3. General license, also called general license, non-exclusive license.
It means that in addition to the right holder and the allowed user to use his patent, the right holder can also allow a third person to use his patent.
It means that the patentee and the permitted user can use the patent, and both the patentee and the licensed user have the right to allow others to use the patent.
5. Cross licensing, also called mutual license.
It means that two patentees allow each other to implement their own patents within the agreed time, territory, and scope. In other words, A allows B to implement A’s patent, and B allows A to exercise B’s patent.
