Office Action

§103
METHOD AND INTEGRALLY BLADED ROTOR FOR BLADE OFF TESTING FINAL OFFICE ACTION This action is in response to the Applicant’s request for reconsideration with Terminal Disclaimer of Feb. 05, 2026. CLAIMS Double Patenting Claims 1 - 20 remain rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1 - 19 of U.S. Patent No. 12,006,830 for the reasons as was set forth in the previous Office Action of Nov. 05, 2025. In response to this rejection, the Applicant filed a Terminal Disclaimer to overcome the rejection. However, the Terminal Disclaimer has not been approved by the Office because the person who signed the Terminal Disclaimer does not have Power of Attorney, and thus, is not of record. The Examiner notes that Power of Attorney can be given to a customer number, wherein all practitioners listed under the customer number have Power of Attorney. If Power of Attorney is given to a list of practitioners by registration number, the list may not comprise more than 10 practitioners, or a separate paper signed by a 37 CFR 1.33(b) party must be in the record identifying which of the practitioners, up to 10, are recognized as having Power of Attorney. A representative of the assignee, who is not of record, cannot sign the Terminal Disclaimer unless it is established that the representative is a party authorized to act on behalf of the assignee. The Applicant is advised to resubmit the Terminal Disclaimer. No fee is required. 35 U.S.C. § 103 In view of the Applicant’s arguments, the rejection of claims 18 - 20 under 35 U.S.C. 103 as being unpatentable over Senoo (2022/0170372) as was set forth in the said previous Office Action has been withdrawn, for the Applicant’s arguments have been considered and have been found to be persuasive. CONTACT INFORMATION THIS ACTION IS MADE FINAL. The Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
