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. 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 appl icant regards as his invention. Claims 1- 16 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 1, the limitation of “a heat exchange plate” is cited in line s 1 and line s 10, it is unclear if they are the same or different.

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 . Claim(s) 9-10 and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Makita (JP2020/009694, Machine Translation) Regarding Claim 9 , Makita et al. is relied upon for the reasons given above, Makita et al. is silent on wherein, a cross-sectional area of a refrigerant flow path of the connection portion is larger than a cross-sectional area of a refrigerant flow path of the first converging portion. A s the reactor cost of construction and efficiency of operation are variables that can be modified, among others, by adjusting the parameters of the cooling circuit , with said construction cost and operating efficiency both changing as the parameters of the cooling circuit , the parameters of the cooling circuit would have been considered a result effective variable by one having ordinary skill in the art before the filing of the invention. As such, without showing unexpected results, the claimed “ wherein, a cross-sectional area of a refrigerant flow path of the connection portion is larger than a cross-sectional area of a refrigerant flow path of the first converging portion. ” cannot be considered critical. Accordingly, one of ordinary skill in the art before the filing of the invention would have optimized, by routine experimentation, the parameters of the cooling circuit to obtain the desired balance between the construction cost and the operation efficiency ( In re Boesch , 617 F.2d. 272, 205 USPQ 215 (CCPA 1980)), since it has been held that where the general conditions of the claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. ( In re Aller , 105 USPQ 223). Regarding Claim 10 , Makita et al. is relied upon for the reasons given above, Makita et al. is silent on wherein the connection portion is disposed between the midpoint of the refrigerant layer in the predetermined direction and the second end portion. A s the reactor cost of construction and efficiency of operation are variables that can be modified, among others, by adjusting the parameters of the cooling circuit , with said construction cost and operating efficiency both changing as the parameters of the cooling circuit , the parameters of the cooling circuit would have been considered a result effective variable by one having ordinary skill in the art before the filing of the invention. As such, without showing unexpected results, the claimed “ wherein the connection portion is disposed between the midpoint of the refrigerant layer in the predetermined direction and the second end portion. ” cannot be considered critical. Accordingly, one of ordinary skill in the art before the filing of the invention would have optimized, by routine experimentation, the parameters of the cooling circuit to obtain the desired balance between the construction cost and the operation efficiency ( In re Boesch , 617 F.2d. 272, 205 USPQ 215 (CCPA 1980)), since it has been held that where the general conditions of the claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. ( In re Aller , 105 USPQ 223). Regarding Claim 12 , Makita et al. is relied upon for the reasons given above, Makita et al. is silent on wherein a cross-sectional area of a refrigerant flow path of the first connection portion is larger than a cross-sectional area of a refrigerant flow path of the second connection portion. A s the reactor cost of construction and efficiency of operation are variables that can be modified, among others, by adjusting the parameters of the cooling circuit , with said construction cost and operating efficiency both changing as the parameters of the cooling circuit , the parameters of the cooling circuit would have been considered a result effective variable by one having ordinary skill in the art before the filing of the invention. As such, without showing unexpected results, the claimed “ wherein a cross-sectional area of a refrigerant flow path of the first connection portion is larger than a cross-sectional area of a refrigerant flow path of the second connection portion. ” cannot be considered critical. Accordingly, one of ordinary skill in the art before the filing of the invention would have optimized, by routine experimentation, the parameters of the cooling circuit to obtain the desired balance between the construction cost and the operation efficiency ( In re Boesch , 617 F.2d. 272, 205 USPQ 215 (CCPA 1980)), since it has been held that where the general conditions of the claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. ( In re Aller , 105 USPQ 223). Claim(s) 3 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Makita (JP2020/009694, Machine Translation) in view of Wang (US Pub No. 2019/0016230) Regarding Claim 3 and 19 , Makita et al. is relied upon for the reasons given above, Makita et al. is silent on further comprising: a thermal expansion valve disposed between the refrigerant input portion and the refrigerant circuit, and between the refrigerant output portion and the refrigerant circuit. Wang et al. teaches a battery thermal management system [abstract] comprising a thermal expansion valve [0046] . Since Makita et al. teaches the use of a refrigerant circuit, it would have been obvious to one of ordinary skill in the art before the filing of the invention to apply the thermal expansion valve of Wang et al. to the refrigerant circuit of Makita et al. as it is merely the selection of a conventional engineering design and one of ordinary skill would have a reasonable expectation of success in doing so. The combination of familiar elements is likely to be obvious when it does no more than yield predictable results. See KSR International Co. v. Teleflex Inc. , 550 U.S. 398, 415-421, 82 USPQ2d 1385, 1395 – 97 (2007) (see MPEP § 2143, A.).
