What are the outstanding substantive features of patent right?

The prominent substantive feature of patent right means that the invented technology is substantially superior to the existing technology, which is not obvious to ordinary technicians in this field, nor can all the necessary technical features of the invention be directly obtained from the existing technology, nor can it be obtained through logical analysis, reasoning or experiment. The so-called remarkable progress means that the economic and social benefits of this technology in practice are obviously superior to the existing technology.
