In recent years, the sales of second-hand goods have formed huge scale and output value benefits in China. With the development of the genuine second-hand goods renovation and sales industry, some disputes about trademark infringement have been triggered. Recently, the trademark infringement dispute of SIEMENS has attracted the attention of the intellectual property industry. Xingruida Company, which is operated by Chen Hua, marks the "SIEMENS" trademark, SIEMENS-specific product model, product description, etc. on its products and labels without permission. The appearance of the logo and fake products are almost the same as the real ones, which makes it difficult for users to distinguish the authenticity. Its act of selling SIEMENS industrial control products as fake ones infringes the plaintiff's trademark right of No.9 G63774 Siemens, causing great economic losses to Siemens and damaging the legitimate rights and interests of users.
