Office Action

§DP
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s supplemental response dated 12/21/2025 is acknowledged and appreciated. The claim amendment to claim 13 has been considered and the 35 U.S.C. 112 rejection is withdrawn. All remaining claims would be allowable over any prior art. However, Double Patenting rejections remain as follows. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 8-14 and 21-26 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1-5 of U.S. Patent No. 12,172,480. Note that the conflicting patent claim includes at least a void and it would have been obvious to one having ordinary skill in the art at the time the invention was made to fabricate the internal material from any of various materials including those claimed, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. Although the claims at issue are not identical, they are not patentably distinct from each other because the patentable subject matter of the instant claims, although not identical to the conflicting claims of the patent, describes at least the same patentable subject matter. Claims 15-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 6 of U.S. Patent No. 12,172,480 in view of Radu et al. (U.S. Patent Application Publication 2016/0272314). The conflicting claim 6 includes all patentable subject matter presented in claim 15 except for the requirement for an altimeter. However, incorporation of various electronic navigation components would necessarily be an obvious addition and Radu et al (henceforth referred to as Radu) teaches a multi-role vehicle that includes an altimeter (par. 78). It would have been obvious to one of ordinary skill in the art at the time of Applicant’s invention to include an altimeter in/on the instant invention as taught by Radu, to indicate the altitude of the vehicle. Further note that the conflicting patent claim includes at least a void and it would have been obvious to one having ordinary skill in the art at the time the invention was made to fabricate the internal material from any of various materials including those claimed, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. Allowable Subject Matter Claims 8-26 would be allowable pending an approved Terminal Disclaimer. The following is a statement of reasons for the indication of allowable subject matter: With respect to claims 8,15 and 21, the closest prior art fails to teach or make obvious, including all the limitations of claims 8, 15 or 21, the structural limitations consistent with the capacity to traverse water, land and to fly. Summary/Conclusion Claims 8-26 are rejected. THIS ACTION IS MADE FINAL. 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 extension fee 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.
