What are the coup of invention patent authorization?

I believe everyone knows that there are three kinds of patents in China: utility model patents, design patents and invention patents; Among them, invention patents are all patents with high value and high gold content. Because the patent examination is different from the other two patents, the invention patent examination is more rigorous and needs substantive examination, so the invention patent authorization is not a simple matter, and the time from application to invention patent authorization is as long as 2-3 years. What process preparations should be made for invention patent authorization? First of all, a successful invention patent should do these tasks well, from patent application, acceptance, preliminary examination, substantive examination, right collection to certificate issuance. Before the application, it is necessary to use the corresponding tools to search whether the patented technology has been copied. It is necessary to prepare documents for accepting the preliminary examination, the most important of which is patent writing, and the patent writing suggestions are handled by qualified institutions. Patent examination is the highlight of patent application, especially invention patent examination. As long as the substantive examination of the patent is passed, it is only a matter of time before the invention patent is awarded. Of course, success in patent application does not mean success. Later, someone may invalidate someone's patent by invalidating it. At this time, we need to do some follow-up filing, such as how to deal with the rejection review and how to deal with some invalid measures. In order to achieve substantial success, the invention patent must first have unique technology, and at the same time, it is necessary to keep the invention patent confidential to avoid the disclosure of patented technology. Moreover, it is necessary to sign a confidentiality agreement when handling with the agency, and the patent search function must be used. It is useless to repeat the patents that have been painstakingly developed with others. It is suggested that the patentee should proceed from these points, and the probability of basically applying for invention authorization is very high.
