Especially for the improved invention, the literature of the prototype of the invention should be deeply and carefully analyzed to clarify its advantages and disadvantages. According to its shortcomings, the task of the invention can be put forward, and the necessary technical characteristics between it and the invention should be determined at the same time.

D. define the scope of protection. How to determine an appropriate scope of protection is very important. Too wide, the examiner can't pass, the patent can't be granted, too narrow, and the interests of the inventor can't be fully protected.
