If the patentee fails to pay the appropriate royalty before the patent right is granted after the publication of the application for a patent for invention, the limitation period for requesting the royalty is two years, counting from the date when the patentee knows or should know that others are using his invention. However, if the patentee knows or should know before the patent right is granted, it shall be counted from the date when the patent right is granted.

Article 60 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).
