Good-faith infringement refers to the act of selling or using products that infringe the patent rights of others without knowing it, and does not bear infringement liability. Some people summarize this situation as bona fide infringement. However, if a seller still sells infringing products in its inventory after being notified by the patentee, it cannot be considered to be ignorant. my country's Patent Law specifically stipulates this situation as "the use or sale for production and business purposes of patented products that are not known to be manufactured and sold without the permission of the patentee or products directly obtained according to patented methods, and the legal origin of the products can be proven 's" behavior.
Here, the scope of conduct is limited to use and sale. For manufacturing or importing, etc., according to current laws, actors should or have an obligation to know whether the products they manufacture or import are patented products.
Legally, the relevant procedures for patent announcement provide a way to understand the patent status. Relevant manufacturers should understand the status of the product under patent law when manufacturing or importing products. Although the Patent Law also has special provisions for the use or sale of infringing products without knowledge, it does not consider this behavior to be an infringement, but only does not bear the liability for infringement for acts performed without knowledge.
