The specific needs are analyzed. The scope of patent protection of the patentee can only be judged by combining its patent pictures and photos. Furthermore, it depends on whether the infringing products and patented products belong to the same kind of products. Finally, compare patented products with infringing products to see whether they are similar or not.
the general idea of concrete similar judgment is: whether ordinary consumers are easy to mislead and distinguish. Of course, the greater the difference, the lower the similarity. It cannot be simply said that there are five differences that do not infringe.
