Professional title evaluation is based on the time of patent application or authorization.

The time of authorization shall prevail, because it is used to evaluate professional titles, and it is uncertain whether it can be authorized after application, so the date of application shall not prevail. In that case, you can apply first and then evaluate the title. In the end, the patent failed, and it was unrealistic to evaluate the title. There are many requirements for professional title evaluation, especially for invention patents, so periodical house reminds people who are preparing patents to look at the document requirements.
