Under what circumstances can I apply for patent reexamination?

1. When an application for a patent for invention, utility model or design is initially examined, it is found that it does not conform to the provisions of Article 44 of the Detailed Rules for the Implementation of the Patent Law, and the defect has not been eliminated after stating opinions, amending or making two corrections, and a decision is made to reject it;

2, the substantive examination of the application for a patent for invention, the provisions of article 3, after the statement of opinions and amendments, still did not eliminate the defects, and make a decision to reject. It should be pointed out that after the patent application is rejected, we can only choose to review this remedy, but we can't directly bring a lawsuit to the court or request administrative reconsideration.
