Office Action

§102 §103
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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 01/06/2025 was filed on the filing date of the instant application. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. The information disclosure statements (IDS) submitted on 02/24/2025 and 03/31/2025 were filed after the filing date of the instant application. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner. 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 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Pocol (US 6,105,659). Regarding claim 1, Pocol discloses a method of simultaneously charging a plurality of thermal batteries, comprising: (a) charging a thermal storage reservoir; and thereafter (b) charging each of the thermal batteries simultaneously using the thermal storage reservoir (refer to fig. 8, and col. 13, lines 60-67, wherein fluid flowing through conduit 160 recharges devices 152a through 152d, and thereby recharging a thermal storage component of each thermal batteries 154a through 154d). 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) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pocol (US 6,105,659). Regarding claim 2, Pocol meets the claim limitations as disclosed above in the rejection of claim 1. Further, Pocol discloses wherein said step of charging the thermal storage reservoir is performed using a conventional heat pump air conditioning, but fails to explicitly disclose using an industrial chiller. However, since Pocol discloses the step of charging the thermal storage reservoir using a conventional heat pump air conditioning system, it appears that Pocol’s charging step would operate equally well using an industrial chiller. Further, Applicant has not disclosed that using an industrial chiller solves any stated problem, indicating simply that “In some embodiments, the external charging source is portable; in some embodiments, the external charging source comprises a portable thermal battery system; in some embodiments, the external charging source is portable; in some embodiments, the external charging source is not portable; and in some embodiments, the external charging source comprises an industrial chiller” (see par. 30 of Applicant’s Specification as filed). Therefore, it would have been obvious to a person having ordinary skill in the art, before the effective filing date of Applicant’s claimed invention to cause the step of charging the thermal storage reservoir of Pocol to be performed using an industrial chiller because this feature appears to be an arbitrary design consideration which fails to patentably distinguish over Pocol. Allowable Subject Matter Claims 3-5 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
