How to calculate the infringement of product appearance patent

Mainly through these points to judge whether the design patent is infringing: 1, determine the protection scope of the design patent. According to the provisions of the Patent Law, the scope of protection shall be based on the pictures or photographs of the patented product of design submitted by the patentee of design to the Patent Office when applying for a patent for design, including front view, top view and side view. Among them, the front view is the most important, because it can best reflect the beauty of design. 2. Determine whether the patented product of design and the infringing product belong to the same or similar goods. If the patented product of design and the alleged infringing product are the same in function and use, they can be identified as the same or similar goods, and the comparison will continue in the third step. If they are different in function and use, we can conclude that they are neither the same goods nor similar goods, and then we can end our infringement judgment step and conclude that patent infringement is not established. 3. Compare the design patent with the alleged infringing product. From the perspective of ordinary consumers, we observe and judge the patented design and the design of the accused infringing product. This should be judged from the whole, and the characteristics of the whole and the part should be comprehensively compared.
