What is the legal compensation for patent infringement?

In Chinese mainland, according to the relevant provisions of the Civil Procedure Law of People's Republic of China (PRC), if the infringement is a major infringement, the amount of compensation can be calculated according to the corresponding multiples of 50,000 yuan to 5 million yuan according to the infringement income, losses caused by the infringement, benefits obtained from the implementation of the infringement, and expenditure on rights protection. For general infringement, the compensation amount can be calculated according to the actual loss caused by the infringement, infringement income and other factors, with the maximum not exceeding 500,000 yuan.

The specific amount of statutory compensation for patent infringement shall be determined according to the provisions of Article 64 of the Patent Law of People's Republic of China (PRC), taking into account the interests obtained by the infringer due to the infringement of others' patents, the losses suffered by the infringed party due to the infringement, and the reasonable expenses paid for the rights protection.

Under normal circumstances, the court will determine the amount of the fine according to the specific circumstances of the case, such as the importance of the patented technology, the degree of the defendant's intention or negligence, and the economic losses caused.
