As long as the application remains pending (which continues up until the issue fee is paid), applicants have the opportunity to correct or update the information in the ADS. This flexibility allows for updates in the inventor's information, the applicant's name, or any other aspects that may need to be altered before the final grant of the patent.

Once the issue fee is paid, the application enters the final stage toward issuance, and the ability to make changes is significantly reduced. Changes after this point can be more complicated and may not be permissible unless they meet specific criteria.

In contrast, the other options present limitations on when corrections could be made. Correcting the ADS until the time of publication does not align with the rules as corrections can be made even after the application is published as long as the issue fee has not been paid. The idea that corrections can
