How to compensate for infringement without patent right?

patent infringement has caused losses to the patentee. after the infringement is determined, the people's court shall order the infringer to make compensation according to the request of the patentee. The amount of compensation can be negotiated by both parties. If negotiation fails, the court can determine the amount of compensation for patent infringement according to the actual loss suffered by the obligee due to infringement according to Article 65 of the Patent Law. 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 benefit of the infringer, it shall be reasonably determined by referring to the multiple of the patent license fee. Specifically, in the case that the loss of the obligee or the benefit obtained by the infringer is difficult to determine, Article 21 of the Supreme People's Court's Provisions on the Application of Law in the Trial of Patent Dispute Cases stipulates that the people's court can reasonably determine the compensation amount with reference to the multiple of the patent license fee according to the type of patent right, the nature and circumstances of the infringement, the nature, scope and time of the patent license, etc. If there is no reference to the patent license fee or the patent license fee is obviously unreasonable, the people's court may determine the amount of compensation according to the type of patent right, the nature and circumstances of the infringement and other factors, in accordance with the provisions of the second paragraph of Article 65 of the Patent Law.
