Office Action

§102 §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 . Election/Restriction Applicant’s election of the invention of Group I, readable on claims 1 through 14, in the reply filed on April 24, 2025 is acknowledged. Because applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.01(a)). Applicant's election with traverse of the fourth species or the embodiment of Figure 4 (readable on claims 1 through 4, 6, 7, and 9 through 21) in the reply filed on December 17, 2025 is acknowledged. The traversal is on the ground(s) that no undue burden would result from examining all of the species. This is not found persuasive because applicant did not provide any evidence that examining one or more additional inventions, including additional claims, would not result in an undue burden The requirement is still deemed proper and is therefore made FINAL. Claims 5 and 8 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to the various non-elected species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on December 17, 2025. Claims 15 through 21 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to the nonelected invention of Group II, there being no allowable generic or linking claim. Election was made without proper traverse in the reply filed on April 24, 2025. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the following features must be shown or the features canceled from the claims, for example: a refrigerant blocking device as recited in claim 3. No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: a first heat-generating device, a second heat-generating device, an electronic control module, and a refrigerant blocking device as recited by the claims. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. 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 1 through 4, 6, 7, and 9 through 14 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. The term “several” in the preamble of claim 1 is a relative term which renders the preamble of the claim indefinite. The term “several” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Thus, as used to qualify the number of temperatures, this term renders the same indeterminate and the claim indefinite. There is insufficient antecedent basis in the claims for the limitation “the components of the cooling circuit” [claim 1, lines 11-12], and it is not clear which particular components are intended to be encompassed thereby, thus rendering indefinite the metes and bounds of protection sought by claim 1 and by all claims depending therefrom. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 7 recites the broad recitation “a plurality of multi-way valves”, and the claim also recites “in particular of proportional multi-way valves” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. With regard to claim 3 as written, it is not entirely clear what is meant by the limitations “the first bypass is implemented by a refrigerant blocking device in the refrigeration machine” (emphasis added). Claim limitation “a refrigerant blocking device” in claim 3 invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. The disclosure is devoid of any structure that performs the function in the claim. Therefore, the claim is indefinite and is rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, each of claim 8 and claim 10 recites the broad recitation “a first bypass”, and the claims also recite “in the form of a first bypass line” which is the narrower statement of the range/limitation. Similarly, claim 11 recites the broad recitation “a second bypass”, and the claim also recites “in the form of a second bypass line” which is the narrower statement of the range/limitation. Also, claim 14 recites the broad recitation “a third bypass”, and the claim also recites “in the form of a third bypass line” which is the narrower statement of the range/limitation. The claims are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Any claim not specifically mentioned in the above rejection is rejected at least as depending from a rejected claim. 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. (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. As best can be understood in view of the indefiniteness of the claims, claims 1 and 2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Enomoto et al. (Pub. No. US 2015/0217622 A1; made of record via IDS). With regard to claim 1 of the instant application, Enomoto et al. (i.e., Figures 10 and 19) discloses a cooling circuit for a vehicle including: a single cooler (i.e., readable on cooler 64) with a coolant inlet and a coolant outlet on line 15 (i.e., as shown in Figure 10 and 19); a refrigeration machine (i.e., including compressor 41 operably connected to shared coolant line 15 as shown in Figure 10) with a coolant inlet and a coolant outlet (i.e., via shared coolant line 15 as shown in Figure 10 and Figure 19); a first heat-generating device (i.e., readable on engine 60) with a coolant inlet and a coolant outlet on line 11 (i.e., see Figure 19); a second heat-generating device (i.e., one of heater 33 and inverter 35, see Figure 19) with a coolant inlet and a coolant outlet (i.e., on respective lines 14 and 16 in Figure 19); a coolant pump arrangement (i.e., including pumps 23 and 24) for pumping the coolant in the cooling circuit; a valve arrangement (i.e., including valve 21) for supplying coolant from the first and second heat-generating devices (i.e., engine 60 and one of heater 33 and inverter 35) to the refrigeration machine and/or to the single cooler 64; and an electronic control module (i.e., as shown in Figure 6) which is connected to the components of the cooling circuit (i.e., as shown in Figure 6) and designed to control the temperature of the coolant at the coolant inlets of the , first and second heat-generating devices(i.e., engine 60 and one of heater 33 and inverter 35) by varying a flow rate of the coolant through the refrigeration machine and/or the single cooler 64, wherein at least one of the first heat-generating device or the second heat-generating device is provided with a bypass. With regard to claim 2 of the instant application, Enomoto et al. discloses that the first heat-generating device or engine 60 (i.e., see Figure 19) is provided with a first bypass 62. The reference thus reads on the claims. Allowable Subject Matter As best can be understood in view of the indefiniteness of the claims, claims 3, 4, 6, 7, and 9 through 14 would be allowable if rewritten without patentably significant broadening to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: the prior art of record does not show nor reasonably suggest a cooling circuit for a vehicle including, in combination, the various elements which are structurally and functionally interrelated as recited in claims 3, 4, 6, 7, and 9 through 14 of the instant application. Conclusion The related and/or prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
