Information Disclosure Statement The information disclosure statement (IDS) submitted on 7/16/2025 is being considered by the examiner. Election/Restrictions Claims 2, 3, 6, 7, 11, 12, 15 and 16 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 8/13/2026. 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. Claim(s) 1 and 10 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Abido et al. (US 2017/0187189). In regard to claim 1: (Original) An integrated photovoltaic power module (Fig. 1 Item 90), comprising: a photovoltaic cell (Fig. 1 Item 92 i.e. many cells); a rechargeable battery (Fig. 1 Item 97 & Pars.

(Withdrawn) Not examined on the merits. 12. (Withdrawn) Not examined on the merits. 15. (Withdrawn) Not examined on the merits. 16. (Withdrawn) Not examined on the merits. Claim Rejections - 35 USC § 103 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 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. Claim(s) 4 and 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Abido et al. (US 2017/0187189) in view of Cao et al. (US 2025/0047188). In regard to claim 4: (Original) Abido discloses the integrated photovoltaic power module of claim 1, including the bidirectional boost converter (Fig. 1 Item 94). However, Abido does not explicitly disclose wherein the bidirectional boost converter comprises a bidirectional CLLC converter. Cao teaches the use of isolated bidirectional DC transformers (DCX) of which a CLLC converter is a popular form (Figs. 1 and 3 Items 1 and 30 & Par. [0002]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have combined the known use of at least one isolated Bidirectional DC transformer specifically a CLLC converter with the known Fault Ride-through and power smoothing system of Abido as doing so would have yielded the obvious results of interfacing between two different DC buses or loads with an increased conversion efficiency (Figs. 1 and 3 Items 1 and 30 & Par. [0002]). In regard to claim 5: (Original) Modified Abido further teaches the integrated photovoltaic power module of claim 4, where the bidirectional CLLC converter isolates ground voltage levels between the first DC link and the second DC link (Figs. 1 and 3 Items 1 and 30 & Par. [0002] i.e. isolation between two DC links). Claim(s) 8, and 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Abido et al. (US 2017/0187189) in view of Cao et al. (US 2025/0047188). In regard to claim 8: (Original) Abido discloses the integrated photovoltaic power module of claim 1, wherein: the power output from the photovoltaic cell (Fig. 1 Item 92 i.e. many cells) is connected to the first DC link (Fig. 1 Item Vpv i.e. wires containing DC voltage) and the battery converter power port (Fig. 1 Item 96, and Vpv i.e. all electrically connected); and the first DC voltage (Fig. 1 Item Vpv i.e. wires containing DC voltage) corresponds to an output voltage of the photovoltaic cell (Fig. 1 Item 92 i.e. many cells). However, Abido does not explicitly disclose the specific arrangement where the power output from the photovoltaic cell (Fig. 1 Item 92 i.e. many cells) is connected directly to the first DC link (Fig. 1 Item Vpv i.e. wires containing DC voltage) and the battery converter power port. Cao teaches the use of isolated bidirectional DC transformers (DCX) of which a CLLC converter is a popular form as well as multiple DC links (Figs. 1 and 3 Items 1 and 30 & Par. [0002]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have combined the known use of at least one isolated Bidirectional DC transformer specifically a CLLC converter with the known Fault Ride-through and power smoothing system of Abido as doing so would have yielded the obvious results of interfacing between two different DC buses or loads with an increased conversion efficiency (Figs. 1 and 3 Items 1 and 30 & Par. [0002]). In regard to claim 9: (Original) Modified Abido further teaches the integrated photovoltaic power module of claim 8, wherein the bidirectional boost converter (Fig. 1 Item 94) is further configured to, when operating, perform maximum power point tracking (Fig. 1 Item 94 & Par. [0044]) for the output voltage of the photovoltaic cell (Fig. 1 Item 92), and the bidirectional battery voltage converter (Fig. 1 Item 96) is further configured to, when operating, follow the maximum power point tracking for the output voltage of the photovoltaic cell (Fig. 1 Item 94, 96 & Par. [0044]). Claim(s) 13 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Abido et al. (US 2017/0187189) in view of Cao et al. (US 2025/0047188). In regard to claim 13: (Original) Abido discloses the method of claim 10, including the bidirectional boost converter (Fig. 1 Item 94). However, Abido does not explicitly disclose wherein the bidirectional boost converter comprises a bidirectional CLLC converter. Cao teaches the use of isolated bidirectional DC transformers (DCX) of which a CLLC converter is a popular form (Figs. 1 and 3 Items 1 and 30 & Par. [0002]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have combined the known use of at least one isolated Bidirectional DC transformer specifically a CLLC converter with the known Fault Ride-through and power smoothing system of Abido as doing so would have yielded the obvious results of interfacing between two different DC buses or loads with an increased conversion efficiency (Figs. 1 and 3 Items 1 and 30 & Par. [0002]). In regard to claim 14: (Original) Modified Abido further teaches the method of claim 13, where the bidirectional CLLC converter isolates ground voltage levels between the first DC link and the second DC link (Figs. 1 and 3 Items 1 and 30 & Par. [0002] i.e. isolation between two DC links). Claim(s) 17 and 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Abido et al. (US 2017/0187189) in view of Cao et al. (US 2025/0047188). In regard to claim 17: (Original) Abido discloses the method of claim 10, wherein: the power output from the photovoltaic cell (Fig. 1 Item 92 i.e. many cells) is connected to the first DC link (Fig. 1 Item Vpv i.e. wires containing DC voltage) and the battery converter power port (Fig. 1 Item 96, and Vpv i.e. all electrically connected); and the first DC voltage (Fig. 1 Item Vpv i.e. wires containing DC voltage) corresponds to an output voltage of the photovoltaic cell (Fig. 1 Item 92 i.e. many cells). However, Abido does not explicitly disclose the specific arrangement where the power output from the photovoltaic cell (Fig. 1 Item 92 i.e. many cells) is connected directly to the first DC link (Fig. 1 Item Vpv i.e. wires containing DC voltage) and the battery converter power port. Cao teaches the use of isolated bidirectional DC transformers (DCX) of which a CLLC converter is a popular form as well as multiple DC links (Figs. 1 and 3 Items 1 and 30 & Par. [0002]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have combined the known use of at least one isolated Bidirectional DC transformer specifically a CLLC converter with the known Fault Ride-through and power smoothing system of Abido as doing so would have yielded the obvious results of interfacing between two different DC buses or loads with an increased conversion efficiency (Figs. 1 and 3 Items 1 and 30 & Par. [0002]). In regard to claim 18: (Original) Modified Abido further teaches the method of claim 17, wherein the bidirectional boost converter (Fig. 1 Item 94) is further configured to, when operating, perform maximum power point tracking (Fig. 1 Item 94 & Par. [0044]) for the output voltage of the photovoltaic cell (Fig. 1 Item 92), and the bidirectional battery voltage converter (Fig. 1 Item 96) is further configured to, when operating, follow the maximum power point tracking for the output voltage of the photovoltaic cell (Fig. 1 Item 94, 96 & Par. [0044]). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Please see attached form pto-892 as well as: Elezab et al.
