When can information in a previously submitted application data sheet be corrected?

The information in a previously submitted application data sheet can be corrected until the issue fee is paid. This is an important time frame because once the issue fee is paid, the application is considered ready for issuance, and any changes to the application data become more challenging.

Up until the issue fee is paid, applicants have the opportunity to correct typographical errors, update inventorship, or make other necessary adjustments without significant procedural hurdles. This flexibility is intended to ensure that the application accurately reflects the technical and legal aspects before it is granted as a patent.

The other scenarios differ in that, once the application is accepted for publication or after issuance, the corrections are no longer permissible during those later stages, making the pre-issue fee payment the critical period for adjustments.
