Office Action

§102 §103 §112
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 . Acknowledgement is made of application #18/133,729 filed on 04/12/2023 in which claims 1-20 have been presented for prosecution in a first action on the merits. Priority As required by M.P.E.P. 201.14(e), acknowledgement is made of applicant's claim for priority based on US provisional applications #63/330,195, filed on 04/12/2022. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 2-9,16-20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, because the specification, while being enabling for claims 8-9,18 and 19 for the staggering configuration of multiple solar-powered charging devices and conductive power transfer between solar-powered charging devices via the use of connectors, does not reasonably provide enablement as to how the wireless power transfer or the inductive power transfer is achieved and performed since having two coils is just not enough to have a wireless and/or inductive power transfer without having a time varying magnetic field. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the invention commensurate in scope with these claims. Having a varying magnetic field generated by some sort of AC signal or inverter that invert the DC power from the solar panels to a high frequency or oscillating magnetic field is necessary to have a wireless or inductive power transfer. These rejections applied to claims 2,16,17 and 20 and there dependent claims therefrom. 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.

The solar panel 112 and the circuit board 114 are integrally attached by electrical connectors to receive electrical power converted from solar energy by the solar panels 112. The solar energy is then converted to electrical energy and stored in an internal battery 115 on the circuit board 114; see col. 4, lines 13-21) using the electrical power generated by the solar panel(112) and stored in the rechargeable battery(115)(see col. 4, lines 17-41). 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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 16-17,20 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Bell US 2022/0224277 A1 Regarding claim 16: Bell at least discloses and shows in Figs. 1-3: A solar-powered charging device(100)(see Figs. 1-3), comprising: a housing(charging base 105 has a housing; see [0023]); a rechargeable battery(rechargeable power supply not shown; see [0023]) disposed within the housing; and a solar panel(110a,110b)([0023],[0026]) positioned along an exterior of the housing(see Figs. 1-3), the solar panel is electrically connected(via retractable cord 135) to the rechargeable battery([0027]). As per the limitations of: “wherein the device is configured to transfer electrical power generated by the solar panel and stored in the rechargeable battery to a second solar-powered charging device when the housing is positioned adjacent to the second solar-powered charging device”, absent a showing of time changing magnetic field, transferring charge by proximity is not possible and thus no patentable weight is given. The same analysis applies to claims 17 and 20. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Salzinger et al., (Salzinger) USPAT 9,255,675 B1 in view of Bell US 2022/0224277 A1. Regarding claim 15, Salzinger discloses all the claimed invention as set forth and discussed above in claim 1 but fails to expressly teach, wherein the solar panel is expandable from a first position to a second position, and has a greater surface area when in the second position relative to the first position. However, Bell teaches factual evidence of a deployable hybrid solar power charger, wherein the solar panel(110) is expandable from a first position(Fig. 3) to a second position(Figs. 1-2)(total surface of panels 110a and 110b), and has a greater surface area when in the second position relative to the first position. Salzinger and Bell are solar power charger analogous art. Therefore it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Bell into the device of Salzinger by having, wherein the solar panel is expandable from a first position to a second position, and has a greater surface area when in the second position relative to the first position, as recited, to have a larger combined panel surface and thereby capturing the most energy from the sun. Accordingly claim 15 would have been obvious.
