Office Action

§102 §103
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 . Detailed Action Claims 1-8 and 10-21 are currently pending. Claim 9 was canceled per Applicant after acknowledgment by Examiner of omission during claim numbering within Non-Final Rejection filed 10/01/2025 . Claims 1-8 and 10-20 remain rejected despite Applicant’s arguments filed 02/27/2026. Claim 21 is newly rejected. Amendment necessitated new grounds of rejection presented within this Office action. Applicant’s amendments to the claims have overcome the 112(b) rejections previously set forth. Response to Applicant arguments can be found at the end of this Office action. This Office action is final. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1, 7, 12, 16 and 21 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Guenther et al. (DE 102016225456 B3). Regarding claim 1: Guenther discloses a superconductor levitation (superlev) vehicle system comprising: a conduit (area under 3; Fig.1), beneath a guideway (3; Fig.1) for a vehicle (4; Fig.1) comprising a magnetic flux source that generates a magnetic flux (23; Fig.1), extending longitudinally along a length of the guideway ( Fig.1); a cryogenic fluid within the conduit (cryostat 16,17; Fig.1); and a superconductor (1,15; Fig.1), immersed in the cryogenic fluid (1,15 within cryostat 16,17; Fig.1) and extending longitudinally along the length of the guideway (12; Fig.1 and see attached EPO translation; Para.[0045]), configured to conduct an electrical current (1,15; Fig.1), repel a magnetic field generated by the magnetic flux source of the vehicle, and levitate the vehicle a distance from the guideway by flux pinning the magnetic flux generated by the magnetic flux source of the vehicle (Para.[0046]). Regarding claim 7: Guenther discloses a superconductor levitation (superlev) vehicle and fluid transportation system comprising: a guideway (3; Fig.1) for a vehicle (4; Fig.10 comprising a magnetic flux source that generates a magnetic flux (23; Fig.1); a conduit (area below 3; Fig.1), beneath the guideway and extending longitudinally along a length of the guideway (Fig.1); a cryogenic fluid within the conduit (cryostat 16,17; Fig.1); and a superconductor (1,15; Fig.1), immersed in the cryogenic fluid (1,15 within cryostat 16,17; Fig.1) and extending longitudinally along the length of the guideway (12; Fig.1 and Para.[0045]), configured to conduct an electrical current (superconductor, 1,15; Fig.1), repel a magnetic field generated by the magnetic flux source of the vehicle, and levitate the vehicle a distance from the guideway by flux pinning the magnetic flux generated by the magnetic flux source of the vehicle (Para.[0046]). Regarding claim 12: Guenther further discloses a system of claim 7, wherein the cryogenic fluid comprises a coolant, coupled to the superconductor, configured to cool the superconductor (1,15 within cryostat 16,17; Fig.1).

Regarding claim 21: Guenther further discloses the system of claim 1, wherein the magnetic flux source is a permanent magnet array or an energized coil (23; Fig.1 and Para.[0018], lines 1-2). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 2, 4, 6, 14 and 17-18 are rejected under 35 U.S.C. 103 as being unpatentable over Guenther in view of Womack, Jr. et al. (US 4845308 A). Regarding claim 2: Guenther does not teach wherein the cryogenic fluid comprises a liquid selected from the group consisting of hydrogen nitrogen, and methane. However, Womack teaches wherein the cryogenic fluid comprises nitrogen (42; Fig.6). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the system of Guenther with the fluid selection of Womack since it is obvious to choose from a finite number of identified, predictable solutions, with a reasonable expectation of success. Regarding claim 4: Guenter teaches a superconductor (1,15; Fig.1) for use along a guideway (3; Fig.1). Guenther does not teach wherein the superconductor transmits electrical power along the guideway. However, Womack teaches wherein the superconductor transmits electrical power along the guideway. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the system of Guenther with the electrical power transmission of Womack to provide an efficient means for power transmission from different locations with a reasonable expectation of success. Regarding claim 6: Guenther does not teach wherein the conduit further comprises: a fluid transportation system for transporting and storing fluids along the conduit. However, Womack teaches a fluid transportation system for transporting and storing fluids along the conduit (Fig.6). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the system of Guenther with the fluid transportation system of Womack to provide an efficient means for fluid transportation from different locations with a reasonable expectation of success. Regarding claim 14: Guenther does not teach wherein the superconductor is configured to transmit and store electrical power. However, Womack teaches wherein the superconductor is configured to transmit and store electrical power (Fig.6). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the system of Guenther with the power transmission system of Womack to provide an efficient means for transmission from different locations with a reasonable expectation of success. Regarding claim 17: Guenther does not teach transporting and storing electrical power using the superconductor. However, Womack teaches transporting and storing electrical power using the superconductor (Fig.6). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the method of Guenther with the electrical power transmission of Womack to provide an efficient means for power transmission from different locations with a reasonable expectation of success. Regarding claim 18: Guenther does not teach transporting and storing the cryogenic fluid using the conduit. However, Womack teaches transporting and storing the cryogenic fluid using the conduit (Fig.6 and 24; Fig.2). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the method of Guenther with the fluid transportation system of Womack to provide an efficient means for fluid transportation from different locations with a reasonable expectation of success. Claims 3, 8, 10-11 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Guenther in view of Kuznetsov (US 5666883 A). Regarding claim 3: Guenther does not teach wherein the superconductor is a superconducting cable. However, Kuznetsov teaches the use of a superconducting cable (Col.12, line 66-Col.13, line 2). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the system of Guenther with the superconducting cable of Kuznetsov to provide efficient power transmission with a reasonable expectation of success. Regarding claim 8: Guenther does not teach wherein the cryogenic fluid comprises a liquid fuel. However, Kuznetsov teaches wherein the cryogenic fluid comprises a liquid fuel (Col.14, lines 6-8). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the system of Guenther with the fluid selection of Kuznetsov since it is obvious to choose from a finite number of identified, predictable solutions, with a reasonable expectation of success. Regarding claim 10: Guenther does not teach wherein the liquid fuel comprises hydrogen, methane, gasoline, or diesel. However, Kuznetsov teaches wherein the liquid fuel comprises hydrogen (Col.14, lines 6-8).
