Article 65 Where a patent is exploited without the permission of the patentee, that is, the patent right is infringed and a dispute arises, the parties concerned shall settle it through consultation; Unwilling to negotiate or failing to do so, the patentee or interested party may bring a suit in a people's court or request the administrative department for patent affairs to handle it. When the administrative department for patent affairs finds that the infringement is established, it may order the infringer to stop the infringement immediately. If a party refuses to accept the decision, he may bring a lawsuit to the people's court in accordance with the Administrative Procedure Law of the People's Republic of China within 15 days from the date of receiving the notice of handling. If the infringer fails to prosecute and stop the infringement upon expiration of the time limit, the administrative department for patent affairs may apply to the people's court for compulsory execution. At the request of the parties concerned, the administrative department for patent affairs may mediate the amount of compensation for patent infringement; If mediation fails, the parties may bring a lawsuit to the people's court in accordance with the Civil Procedure Law of People's Republic of China (PRC).

Article 71 The amount of compensation for infringement of a patent right shall be determined according to the actual losses suffered by the obligee or the interests gained by the infringer due to the infringement; If it is difficult to determine the loss of the obligee or the interests of the infringer, it shall be reasonably determined by reference to the multiple of the patent license fee. For intentional infringement of patent rights, if the circumstances are serious, the amount of compensation can be determined in accordance with the above method. If it is difficult to determine the loss of the obligee, the benefits obtained by the infringer and the patent license fee, the people's court may determine the amount of compensation to be between 30,000 yuan and 5 million yuan according to the type of patent right, the nature and circumstances of the infringement, etc. The amount of compensation shall also include the reasonable expenses paid by the obligee to stop the infringement. In order to determine the amount of compensation, the people's court may order the infringer to provide the account books and materials related to the infringement if the obligee has tried his best to provide evidence and the account books and materials related to the infringement are mainly held by the infringer; If the infringer fails to provide or provide false account books and materials, the people's court may determine the amount of compensation with reference to the claims of the obligee and the evidence provided.
