Further, the use of controllers that controls switching valves in thermal management systems of vehicles is old and known in the art, as taught by Yeon, par. 0016). the plurality of modes (figs. 4-12) includes a first mode (fig. 10) and a second mode (fig. 4), in the first mode (fig. 10), the switching valve (2-6) is configured to connect the first circuit (25) and the second circuit (where battery 92 is) together in series (fig. 10) [par. 0080], and in the second mode (fig. 4), the switching valve (2-6) is configured to connect the first circuit (25) and the second circuit (where battery 92 is) together in parallel, to flow part of the heat medium flowing in the second circuit (where battery 92 is) to the first circuit (25) via the switching valve (2-6) (fig. 4) [par. 0064-0065].

Regarding claim 12 , Kim discloses: the plurality of ports including: two ports (at 2) each connected to the first circuit (25), and two other ports (at 5) each connected to the second circuit (where battery 92 is) (figs. 4-12). Regarding claim 13 , Kim discloses: a thermal management system including the switching valve (2-6) and the thermal management circuit being mounted on a vehicle [par. 0002] including a driving device (91) and a battery (92) (figs. 1-2), the first circuit (25) being a circuit in which the heat medium flows to exchange heat with the driving device (91) (figs. 1-12) [par. 0043], and the second circuit (where battery 92 is) being a circuit in which the heat medium flows to exchange heat with the battery (92) (figs. 1-2) [par. 0044].

Regarding claim 16 , Kim discloses: each of the second circuit (where battery 92 is) and the third circuit includes no reservoir (see annotated fig. 4-KIM, page 5). Response to Arguments Applicant's arguments with respect to claim 1 filed on 03/03/2026 have been fully considered but they are not persuasive. In pages 7-8, Applicant argues that “ all passages of Kim which pass through battery 92 include a reservoir, be it tank 94, mixing tank 7, or both. There is no passage that does not a reservoir or tank with a coolant storage function .” Examiner respectfully disagrees. As stated in the rejection above, the Examiner has interpreted the second circuit as being the passage where battery 92 is arranged, between valve 5 and valve 6, seen in figure 1, which only includes a coolant heater 93, the battery 92, and a pump 58. In this case, the overly broad language of claim 1 allows a broad interpretation of the claim which the combination of Kim and Yeon reads on. Please refer to the rejection above. For clarity, the Office Action mailed 12/31/2025 includes an inadvertent oversight. The heading introducing the rejection to all claims (1-9) inadvertently referred to Section 103 when the arguments rejecting claims 6-7 and 9 clearly correspond to Section 102. This oversight has been clarified in the instant Office Action, which maintains the same grounds of rejection for claims 1-5 and 8 under Section 103 and for claims 6-7 and 9 under Section 102. Conclusion 07-39 AIA 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.
