What should the patentee do if he encounters a retrial?

What should the patentee do if he encounters a retrial? When applying for a patent, he does not apply for a patent according to the basic requirements of the patent application, then the patent application will be asked to reply, or directly rejected by the Intellectual Property Office. So how to deal with this kind of thing? What important preparations need to be made is a topic worthy of the patentee's attention. What should the patentee do if he encounters a retrial? The first thing to do when applying for a patent is to sort out the idea of the patent application process. If you apply for a patent under unknown conditions, it will be inconsistent with the safety preparation of patent application; Patents are usually applied first, and then the Intellectual Property Office will accept the documents of patent application. Once accepted, the patentee's application documents will be preliminarily examined. For invention patents, substantive examination is needed. If it is an application for a patent for appearance and an application for a patent for utility model, the preliminary examination will be directly completed. So the point is, which procedures does patent examination generally appear in? Taking the invention as an example, from application, acceptance, preliminary examination, actual examination, authorization to certification, the patent reexamination procedure takes place in the preliminary examination stage and substantive examination stage of the patent; If the patent fails to pass the preliminary examination, it will be rejected directly after many patent submissions, and so will the substantive examination. However, if it is rejected, the patentee will have another chance to review it. Unlike the appearance patent, the utility model patent has only one preliminary examination link, so it is generally either passed or not. But some patentees may ask, what if they still fail to pass the examination? Actually, there is another trick. If it is not in the application process, the patentee can see whether to bring relevant patent litigation to the court according to his own situation.
