How to exempt patent infringement?

Legal analysis: 1. Those who can prove the legal source of the products shall not be liable for compensation. Legal source refers to obtaining products through legal sales channels, usual sales contracts and other normal commercial means. For legitimate sources, users, promised sellers or sellers shall provide relevant evidence in line with trading habits.

Second, subjectivity is good.

3. If the obligee proves that the user has not paid the consideration or the consideration is obviously unreasonable, it does not meet the constitutive requirements of exemption from stopping the infringement, and the user should still bear the civil liability for stopping the use.

Legal basis: Article 77 of the Patent Law of People's Republic of China (PRC) uses, promises to sell or sells an infringing patented product for the purpose of production and operation, and does not know that the product is manufactured or sold without the permission of the patentee, and shall not be liable for compensation.
