Yes, an applicant can voluntarily identify grace period inventor-originated disclosures. The MPEP encourages this practice: "Applicants can include a statement identifying any grace period inventor-originated disclosures in the specification upon filing. See 37 CFR 1.77(b)(6) and MPEP § 608.01(a). An applicant is not required to identify any prior inventor-originated disclosures or to use the format specified in 37 CFR 1.77, but identifying any such prior disclosures may expedite examination of the application and save applicants (and the Office) the costs related to an Office action and reply." This voluntary disclosure can be beneficial because: It can expedite the examination process It may save costs associated with Office actions and replies It helps establish that a disclosure falls under the grace period exception While not required, proactively identifying these disclosures can streamline the patent application process.
