When dealing with patent infringement disputes at the request of the patentee or any interested party, the department in charge of patent-related work of the local people's government may deal with the cases of infringement of the same patent right within its administrative area in a combined manner; for cases infringing the same patent right across administrative areas, it may request the department in charge of patent-related work of the local people's government at a higher level to deal with the matter. 

Article 71. The amount of compensation for patent right infringement shall be determined on the basis of the actual losses suffered by the right holder as a result of the infringement or the profits earned by the infringer as a result of the infringement. Where it is difficult to determine the losses suffered by the right holder or the profits earned by the infringer, the amount shall be reasonably determined by reference to the multiple of the amount of the royalties for the patent license. For intentional infringement of a patent right, if the circumstances are serious, the amount of compensation may be determined at not less than one time and not more than five times the amount determined in accordance with the above-mentioned method. 

Where it is difficult to determine the losses suffered by the right holder, the profits earned by the infringer and the royalties for the patent license, the people's court may determine the amount of compensation, which is not less than RMB 30,000 Yuan and not more than RMB 5,000,000 Yuan, in light of such factors as the type of the patent right, the nature and the circumstances of the infringing act.

Article 73. In order to stop patent infringement, in cases where the evidence might be destroyed or where it would be difficult to obtain in the future, the patentee or the interested party may, before filing a lawsuit, apply to the people's court for evidence preservation in accordance with the law. 

Article 74. The period of limitation for action against the infringement of a patent right is three years, beginning from the date on which the patentee or interested party knows or should have known of the infringing act and the infringer. 

Where an appropriate royalty is not paid for exploiting an invention during the period from the publication of the application to the grant of the patent right, the limitation period for taking legal action by the patentee for requesting the payment of royalties is three years, beginning from the date on which the patentee knows or should have known of the exploitation of his or its invention by another person.

(4) where the relevant patent is used specially for the purposes of scientific research and experimentation; or
