A: If you want to publish an application for an invention patent in advance, you can submit a statement to China National Intellectual Property Administration requesting to publish an invention patent in advance. Generally speaking, if the amendment statement is submitted at the time of application, it will be published after the preliminary examination of the application, about 3-4 months after the application date. Under the condition that no prior disclosure is required, it is disclosed after the application of 18; If it is required to be made public in advance, it will be made public immediately after the first trial is passed, and it will be made public after the public preparation stage, usually for half a year or earlier.
After the application is published, it may not necessarily enter the actual trial. Because the substantive examination procedure starts only after the applicant has gone through the formalities of requesting the actual examination in China National Intellectual Property Administration and paid the actual examination fee.
