What is one of the types of corrections permitted under Rule 1.48 for Provisional applications?

Under Rule 1.48, one of the permitted corrections for provisional applications is adding or deleting inventors by filing an executed Declaration. This rule acknowledges that changes in inventorship can occur, and the patent office allows applicants to accurately reflect the true inventive contributions to the application.

This process is essential to maintaining the integrity of the patent system, ensuring that all individuals who contributed to the conception of the claimed invention are officially recognized. By allowing these changes, the rule supports clarity in patent ownership and helps avoid disputes regarding inventorship.

Other options represent actions not permissible under Rule 1.48. Changing the invention's specification, for example, would not be allowed since provisional applications are typically expected to be based on the original disclosure to preserve the filing date. Changing the filing date is not permitted as it can undermine the legal standing of the application. Finally, compiling claims after filing a provisional application does not apply as well because provisional applications do not require claims at the time of filing; they are used mainly to establish an early effective filing date to protect the inventive concept.
