Patent infringement refers to the act of using a patent for profit without the consent of the patentee within the validity period of the patent, no matter in what way. If the patented product is exported without the permission of the patentee, it is an infringing patent.
Compensation for losses is one of the main ways to identify patent infringement and the infringer to bear civil liability. Patent infringement has caused losses to the patentee. After the infringement is determined, the people's court shall, at the request of the patentee, order the infringer to compensate for the losses. The amount of compensation can be negotiated by both parties. If negotiation fails, the court may determine the amount of compensation for patent infringement according to Article 65 of the Patent Law and the actual losses suffered by the obligee due to infringement. If the actual loss is difficult to determine, it can be determined according to the interests obtained by the infringer due to 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.
