Under Rule 1.48 for Non-Provisional applications, which of the following is a type of correction allowed?

The addition of inventors due to an error at the time of filing is an important provision under Rule 1.48 of the MPEP, which allows for specific corrections to be made to a non-provisional application. This rule recognizes that mistakes may occur when identifying inventors during the initial filing of a patent application.

When an applicant comes to realize that certain individuals who contributed to the invention were omitted from the application, Rule 1.48 provides a mechanism to correct this oversight. By permitting the addition of inventors, it ensures that all rightful contributors to the invention are properly recognized and can participate in the patent process. This correction helps to uphold the integrity of patent rights by ensuring that all inventors are accurately listed and can thus share in the rights and responsibilities associated with the patent.

In contrast, while deleting claims, changing the title, or including additional fees may be necessary in some contexts, they do not fall under the specific corrections allowed by Rule 1.48 for non-provisional applications. Correcting inventorship is particularly significant because patent rights are fundamentally based on the contributions of the inventors, making it crucial to have an accurate representation of who those individuals are in the application.
