There are three types of patent licensing implementation contracts: (1) exclusive licensing implementation contracts; (two) the exclusive license to implement the contract; (3) General license implementation contract. Different types of licensing contracts have different rights for patentees.
If both parties sign an exclusive license contract, the patentee shall not exploit the patent during the license period, nor shall he license the patent to any unit or individual other than the licensee.
Where an exclusive license contract is signed, the patentee may exploit the patent on his own within the license period, but he may not license the patent to any unit or individual other than the licensee.
If a general licensing contract is signed, the patentee can not only exploit the patent himself, but also license the patent to units or individuals other than the licensee within the licensing period.
However, no matter what kind of licensing contract, the licensee has no right to license the patentee's patent right to others.
