How to know the time of patent authorization inquiry? Patent authorization is one of the topics that patentees are most concerned about. From patent research and development to patent application and finally to patent examination, authorization is related to the patentee's previous efforts, so decisive examination and understanding of patent authorization is the ultimate goal; It is necessary for the patentee who is anxious to know whether the patent is authorized as soon as possible to master the way of patent authorization inquiry. How to know the time of patent authorization inquiry? First of all, there should be a time limit in the patent application process, so that the patent can roughly understand what the patent application process is like and how long it will take for the patent to come down. First submit the patent application (preparation materials), then the patent office will accept it, followed by the preliminary examination of the patent. It takes about 3 months for the preliminary examination office of the Patent Office to examine whether it meets the requirements of formal examination. After the expiration of 18 months from the date of filing, the Patent Office will disclose the contents of the application for a patent for invention, except for the application that is disclosed in advance. Of course, if it is a patent for utility model or an application for a patent for appearance, it won't take that long. We usually know the result within half a year. It's a little late because the invention patent needs substantive examination. Within three years from the date of application, the Patent Office will make a request for substantive examination and pay the request fee for substantive examination. After acceptance, the Patent Office will start the substantive examination procedure. The applicant agrees to submit a request for substantive examination when submitting a patent application, and pay the request fee for substantive examination. That is to say, generally speaking, it takes 2-3 years to know the result of patent application for invention patents, and it only takes half a year to complete utility model patents, which can be directly queried through official website system. Patent authorization inquiry can also be notified through the patent office; If the patentee thinks it will take a long time, then he can also use the way of patent agency. In this way, he will be angry that he is not staring at the patent, and the patent agency will inform you directly.
