What is the patent application or confidential patent for top secret state secret technology during the confidentiality period?

During the confidentiality period of top-secret state secret technology, you can't apply for ordinary patents or open secret patents, because it will expose the contents of state secret technology. But you can apply for a secret patent or a secret invention patent. These patent applications will not be made public, and will only be made public after the confidentiality expires. The application for a confidential patent shall comply with the provisions of the Patent Law and its detailed rules for implementation, and shall be approved by the state secrecy department.
