Office Action

§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 . Response to Amendment The amendments filed on 1/27/2026 does not put the application in condition for allowance. Examiner withdraws all rejections in the prior office action due to the amendments. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 15-28 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding Claim 15, the limitation of “the first vacuum tube’s metal tube” lacks antecedent basis. Regarding Claim 25, the limitation of “the second vacuum tube’s metal tube” lacks antecedent basis. Regarding Claim 26, the limitation of “the vacuum tube’s metal tube” lacks antecedent basis. Regarding Claim 27, the limitation of “the first optical focusing reflector’s curve surface”, “the second optical focusing reflector’s curved surface”, and “the second optical focusing reflector’s vacuum heat concentration tube” lacks antecedent basis. Claims 16-24, and 28 are also rejected since they depend on claims 15 and 26 respectively. Allowable Subject Matter The following is an examiner’s statement of reasons for allowance: Stettenheim (US Pub No. 2013/0192226), Ashkin (US Pub No. 2010/0139739), Weissmann (US Pat No. 7964978) and Carroll (US Pub No. 2004/0231329) are the closest prior art. Stettenheim et al. teaches an illustrative advanced cavity receiver that resembles receiver 400 in FIG. 4 [0140], the receiver 400 comprises a tubular shell 402, a heat-absorbing element 404 through which a heat-transfer fluid 406 can flow, reflective parabolic sidewalls 408, 410, an aperture 412, a transparent aperture cover 414 spanning the aperture 412, an insulating jacket 416 partially surrounding the heat-absorbing element 404, a planar (flat) absorbing surface 418 coated with an absorbent coating and exposed to light entering the aperture 412, and an optical cavity 420 bounded by the absorbing surface 418, sidewalls 408, 410, and aperture cover 414 [Fig. 4, 0133]. Ashkin et al. teaches Collector 10 is disposed horizontally, and is slightly raised off the ground by a support arrangement 150 (such as a pair of blocks). A PV/thermal receiver 160 is shown in this embodiment as disposed behind exit face 22 of collector 10, in a position to receive the collected and concentrated solar rays [Fig. 8, 0052]. Weissmann et al. teaches an improved wind turbine using magnetic levitation to reduce friction in the turbine and mountings [Fig. 1, C3 ln 45-55] Carrol et al. teaches the construction of the absorber tube 36 is shown. To reduce convective heat loss to the atmosphere, the absorber tube 36 has a glass vacuum tubular jacket 44 [Fig. 2, 0018]. Modified Stettenheim et al. teaches limitations of the claims but does not disclose the limitations of “the working medium airflow pushes push multidimensional magnetic levitation state multi-stage turbines to drive multidimensional magnetic levitation state polystage generators to generate electric power with thereby generating electricity using the high-intensity parallel cold beams in via photovoltaic cells and with invisible the infrared light via thermal mechanical conversion.” in claim 1, “a plurality of heat exchangers each of which having a focusing photovoltaic cell panel placed on its light-facing side; wherein for a first focusing reflector of the plurality of optical focusing reflectors, a first vacuum tube of the plurality of vacuum heat concentrating tubes corresponding to the first focusing reflector, and a first heat exchanger of the plurality of heat exchangers corresponding to the first focusing reflector, the first focusing reflector is coated with a first thermal reflective film that reflects a first set of infrared light in the incoming sun light to a first focal point of the plurality of focal points and allows a first set of visible light in the incoming sun light to pass through, wherein the first vacuum tube is placed at the first focal point, the first set of infrared light passing into the first vacuum tube heats the first vacuum tube's metal tube and the first heat-transferring medium, wherein the first heat-transferring medium is used to generate electricity via thermal mechanical conversion, and the cold-light reflective film of the first vacuum tube reflects the first set of visible light to be parallel cold beams toward the first heat exchanger, wherein the focusing photovoltaic cell panel of the first heat exchanger generates electricity based on the parallel cold beams.” In claim 15, and “wherein the cold-light reflective film of the vacuum tube allows infrared light at the focal point to pass into the vacuum tube, heating the vacuum tube's metal tube and the first heat-transferring medium, and the heat-transferring medium is used to generate electricity via thermal mechanical conversion, and the cold-light reflective film of the vacuum tube reflects visible light at first focal point as parallel cold beams toward the heat exchanger, allowing the focusing photovoltaic cell panel of the heat exchanger to generate electricity based on the parallel cold beams, and allowing infrared light in the parallel cold beams to pass through the focusing photovoltaic cell panel of the heat exchanger and be absorbed by the second heat-transferring medium in the heat exchanger for generate electricity via thermal mechanical conversion.” in claim 26. These references, nor any other reference or combination of references in the prior art suggest or render obvious the limitations of “the working medium airflow pushes push multidimensional magnetic levitation state multi-stage turbines to drive multidimensional magnetic levitation state polystage generators to generate electric power with thereby generating electricity using the high-intensity parallel cold beams in via photovoltaic cells and with invisible the infrared light via thermal mechanical conversion.” in claim 1, “a plurality of heat exchangers each of which having a focusing photovoltaic cell panel placed on its light-facing side; wherein for a first focusing reflector of the plurality of optical focusing reflectors, a first vacuum tube of the plurality of vacuum heat concentrating tubes corresponding to the first focusing reflector, and a first heat exchanger of the plurality of heat exchangers corresponding to the first focusing reflector, the first focusing reflector is coated with a first thermal reflective film that reflects a first set of infrared light in the incoming sun light to a first focal point of the plurality of focal points and allows a first set of visible light in the incoming sun light to pass through, wherein the first vacuum tube is placed at the first focal point, the first set of infrared light passing into the first vacuum tube heats the first vacuum tube's metal tube and the first heat-transferring medium, wherein the first heat-transferring medium is used to generate electricity via thermal mechanical conversion, and the cold-light reflective film of the first vacuum tube reflects the first set of visible light to be parallel cold beams toward the first heat exchanger, wherein the focusing photovoltaic cell panel of the first heat exchanger generates electricity based on the parallel cold beams.” In claim 15, and “wherein the cold-light reflective film of the vacuum tube allows infrared light at the focal point to pass into the vacuum tube, heating the vacuum tube's metal tube and the first heat-transferring medium, and the heat-transferring medium is used to generate electricity via thermal mechanical conversion, and the cold-light reflective film of the vacuum tube reflects visible light at first focal point as parallel cold beams toward the heat exchanger, allowing the focusing photovoltaic cell panel of the heat exchanger to generate electricity based on the parallel cold beams, and allowing infrared light in the parallel cold beams to pass through the focusing photovoltaic cell panel of the heat exchanger and be absorbed by the second heat-transferring medium in the heat exchanger for generate electricity via thermal mechanical conversion.” in claim 26 in conjunction with the remaining limitations of the claims. Therefore; claims 1, 3-6, and 10 are allowed, and claims 15-27 are allowed once the rejections under 35 USC 112 are overcome. Conclusion 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 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.
