Patented products applied by others have different production methods and different appearances. Infringement? The other party applied for a utility model.

First of all, the difference in manufacturing methods only shows that the method of producing the product is different, but if the structure and function of the product produced are the same as those of the patent, it may constitute infringement. For a simple example, the hammer comprises a hammer head, a hammer handle and a tail-end lifting ring. The invention lies in the assembly of the tail-end lifting ring, the hammer handle and the lifting ring. When there is a new hammer, it also includes a hammer head, a hammer handle and a lifting ring at the end. In the invention, the lifting ring is also added at the end, and the lifting ring and the hammer handle are integrally formed through a certain process. In this way, although there are some differences in production methods and appearance, there will be disputes and infringement because the corresponding technical means (adding rings) are adopted to solve the same technical problem (convenient hanging).
