Legal analysis: the reasonable expenses paid to stop the infringement is one of the factors that the court needs to consider when comprehensively judging the amount of damages. Judging from the Patent Law of 2008, the provision on reasonable expenses is placed in the last sentence of the first paragraph of Article 65, which means that common expenses are additional compensation according to the compensation amount determined by the loss of the obligee, the illegal profit of the infringer or a reasonable multiple of the royalties, and the compensation finally obtained by the obligee should be additional compensation according to the actual loss, the illegal profit of the infringer or a reasonable multiple of the royalties, and the compensation finally obtained by the obligee should be actual loss and infringement. If it is difficult to adopt the three methods specified in the first paragraph of this article, and the court finally chooses to determine the amount of compensation by means of statutory compensation, the above reasonable expenses cannot be added to the statutory compensation already determined, because the total amount of compensation determined by the court at the time of statutory compensation should already include the reasonable expenses paid to stop the infringement.
Legal basis: Article 65 of the Patent Law of People's Republic of China (PRC) determines the amount of compensation for patent infringement according to 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. The amount of compensation shall also include the reasonable expenses paid by the obligee to stop the infringement. If it is difficult to determine the loss of the obligee, the benefit of the infringer and the patent license fee, the people's court may determine to pay compensation ranging from one yuan to ten thousand yuan according to the type of patent right, the nature and circumstances of the infringement, etc.
