Hello!
First of all, you need to look at the type of patent you are applying for.
1. Invention patent: The cycle is long, about 2 years. Due to the difficulty, acceptance does not mean authorization.
2. Utility and appearance patents: The cycle is short, about 6-8 months. Since there is only formal examination, it is generally authorized after acceptance.
I don’t know whether the third author you mentioned specifically refers to the third applicant or the third inventor; if the third applicant is a third applicant, he can apply for a copy of the patent certificate (in the case of multiple applicants, only the first applicant The person can get the original patent certificate); if it is a third inventor, there is no certificate to get.
