What is "patent application disclosure"? I saw it when I was looking up American patents.

The patent application was made public and failed to pass the examination of the Patent Office. Specifically, you can check the status of the application in official website (know the serial number, WeChat official account or patent number of the application), and the data is updated once a week: http://portal.uspto.gov/external/portal/pair enters the page, enters the verification word according to the prompt, and then enters the page of digital input inquiry. The result page will display the time of the whole review process, the opinions issued by the Patent Office and the applicant's defense documents.
