What are the elements that constitute the infringement of utility patents?

A utility patent is regarded as infringement if it meets the following conditions: the elements that constitute patent infringement include two aspects: formal conditions and substantive conditions. First, the form requirement (1) relates to a valid China patent; (2) The implementation must be carried out without the permission or authorization of the patentee; 3) The implementation behavior must be aimed at production and operation. Second, the substantive elements constitute the substantive elements of patent infringement, that is, technical conditions, and whether the substantive implementation behavior belongs to the scope of patent protection.
