If a new practical patent complaint exists, can the e-commerce platform protect customers from prosecution?

yes. The plaintiff should ensure that the utility model patent has been authorized and pay the annual fee on time; Secondly, it takes 1 to 3 months to search the utility model patent to determine the novelty and creativity of the patent, which can be achieved by requesting the patent office to issue a search report; Thirdly, investigate and collect evidence, and collect the evidence of the infringer's production, sale and use of patented products. It is more critical to compare the alleged infringing products with the claims of utility models to see whether the accused infringing products cover all the necessary technical features of a claim of utility models. If they are completely covered, they will determine the infringement, and if they are not covered, they will see whether the equivalent technical features are replaced.
