Actually, think about it. What is propaganda? You can't find it now that it's published? If you can't find it, what will you promote?
If it is not required to be published in advance, the invention patent will be published at the end of 65,438+08 months. At this time, the application content can be found, but the patent right has not yet been obtained. Generally, the applicant himself will conduct substantive examination. If there is time, the request for substantive examination shall be made within 3 years from the date of application.
There is no public procedure for utility model patent. If the application date is fast, it is possible to get the patent certificate and announce it in nine months (in the patent law, publicity and announcement are two concepts), and it can also be found at this time.
