Advantages of early public extension of patent substantive examination system

The advantages of early public delayed examination system are: accelerating the exchange of patent information; Give the applicant sufficient time to consider whether and when to make a request for substantive examination. Some applicants will give up the request for substantive examination according to the actual situation, which avoids being rejected from the applicant's point of view, saves the examination cost, reduces the examination and approval workload of the patent office, and enables the examiner to concentrate on examining and handling those patent applications that request substantive examination. However, this kind of examination system is too lengthy, which makes the patent application in an unresolved state for a long time and easily leads to disputes. In addition, the period from early publicity to patent certificate issuance is a temporary legal protection period, during which the rights and interests of the applicant cannot be fully and reliably protected. Generally speaking, the early public delayed examination system combines the advantages of formal examination and immediate examination, solves the sharp contradiction in the history of patent system development, and is adopted by more and more countries.
