1. Ensure that he is the legal owner of the patented technology provided, and that the patented technology provided is complete, error-free and effective, and can achieve the purpose agreed in the contract;
2. According to the contract, license the transferee to exploit the patent, deliver the technical data related to the exploitation of the patent, and provide necessary technical guidance;
3. Undertake the obligation of confidentiality;
4. The licensor of an exclusive license contract shall not conclude a patent license contract with a third party for the same patent within the scope that the licensor has already licensed the patent. The transferor of the exclusive license contract shall not exploit the patent within the scope of the patent that has been licensed to the transferee. An exclusive license contract means that after the licensor grants the patented technology to the transferee in a certain area or within a certain period, it no longer enjoys the right to exploit the patented technology within that scope and within that period, nor does it enjoy the right to distribute the patented technology to a third party. An exclusive license contract means that the transferor reserves the right to exploit the patented technology within the scope and time limit granted to the transferee.
In the patent licensing contract, the transferee's main obligations are:
1. Pay the price according to the contract.
2. Implement the patented technology according to the scope, method and time limit agreed in the contract, and pay the annual use fee as agreed.
3. Without the consent of the transferor, the third party outside the contract shall not be allowed to exploit the patented technology.
4. Undertake the obligation of confidentiality.
Legal basis: The patent right declared invalid in Article 47 of the Patent Law of People's Republic of China (PRC) is regarded as nonexistent from the beginning. The decision to declare the patent right invalid has no retrospective effect on the patent infringement judgments and conciliation statements made and executed by the people's court before the patent right was declared invalid, the decisions on handling patent infringement disputes that have been performed or executed, and the patent licensing contracts and patent transfer contracts that have been performed. However, if the patentee's malice causes losses to others, it shall make compensation. If the patent infringement compensation, patent exploitation fee and patent transfer fee are not returned in accordance with the provisions of the preceding paragraph, which obviously violates the principle of fairness, they shall be returned in whole or in part.
