What is preview? How to avoid patent rejection? Patent application may go through many processes, and there are actually many kinds of classified examination of patent application. We can understand that the common patent examination in the application process, such as patent preliminary examination and patent substantive examination, is a necessary process of patent application. Of course, substantive examination is the only examination in invention patents; But do you know what pre-censorship is? This may be a bit confusing for many patentees. How to avoid patent rejection Next, we mainly talk about what is pre-trial. Originally, it refers to the procedure that the original examination department of China National Intellectual Property Administration, which made a decision on rejecting a patent application, reexamines the request and application after accepting the request for reexamination, and makes a decision on whether to revoke the original rejection decision. Simply put, it is because the patent does not meet the requirements of patent examination, and the patent office requires correction and defense. And it is at the final stage of examination to see if the patent should be passed. The result of the patent re-examination stage is whether the pre-examination has been carried out in time. There is a reply in the patent examination, and the second reply is the number of examinations. If the reexamination evidence is sufficient or the revised document text overcomes the defects in the original application, it is agreed to cancel the original decision to reject the application; But failed to overcome the defects, directly rejected, rejected the pre-trial decision. On the other hand, how to avoid the occurrence of pre-censorship? Patent examination is actually uncertain, but through some preliminary preparations, the application process can be improved more or less. One of the reasons why the examination failed was that the patent application search failed, which eventually led to technical duplication with others, and the other was that the patent writing was not in place and the claim was not sufficient. If these preparations are made in advance, the review problem will be solved easily.
