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) 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park et al. as applied to claim 6 above, and further in view of Cui et al. (CN 106802039).
Regarding claim 7, Park et al. further discloses wherein the refrigerant flow direction-changing valve has an electronic expansion valve (EXV) structure capable of controlling the refrigerant amount (see at least valve #2030 of valve combination #2200/#2030, which is an electromagnetic expansion valve and thus considered capable of meeting the claimed function), and wherein the first expansion valve has an electronic expansion valve (EXV) structure capable of controlling the refrigerant amount (see at least valve #2010, which is an electromagnetic expansion valve and thus considered capable of meeting the claimed function).
Park et al. does not disclose and the second expansion valve is a thermostatic expansion valve (TXV) performing only the expansion function.
However, substitution of a thermostatic expansion valve for the solenoid expansion valve disclosed by Park et al. was known in the art, as evidenced by Cui et al. (see at least “the second throttle is an electronic expansion valve, or series of the capillary and solenoid valve has completely closed function, or thermostatic expansion valve arranged and with complete closing function of the electromagnetic valve in series, the third throttle is an electronic expansion valve. or capillary set in series with the electromagnetic valve has completely closed function, or thermostatic expansion valve arranged and with complete closing function of the electromagnetic valve in series.”).
It would, therefore, have been obvious to one having ordinary skill in the art before the effective filing date of the invention to provide the second expansion valve of Park et al. with and the second expansion valve is a thermostatic expansion valve (TXV) performing only the expansion function, since, as taught by Cui et al. substitution of the two valve types was old and well-known in the art and would provide the predictable benefit of controlling the cost/function of the system. Examiner notes that use of the thermostatic expansion valve in place of the solenoid expansion valve is deemed to meet the functional recitation.
Claim(s) 9-11 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park et al. as applied to claim 6 above, and further in view of An et al. (KR 20210079741: cited by Applicant: English translation provided by Examiner).
Regarding claim 9, Park et al. does not disclose further comprising: a dehumidification line which branches off downstream of the indoor heat exchanger in the refrigerant flow direction and connects upstream of the evaporator, wherein the dehumidification line is connected between the second expansion valve and the evaporator.
An et al. teaches another vehicle heat pump system comprising: a dehumidification line which branches off downstream of the indoor heat exchanger in the refrigerant flow direction and connects upstream of the evaporator, wherein the dehumidification line is connected between the second expansion valve and the evaporator (see at least line #BR2 which branches off downstream of indoor heat exchanger #1200 and connects between expansion valve #2300 and evaporator #1500).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to provide the system of Park et al. with further comprising: a dehumidification line which branches off downstream of the indoor heat exchanger in the refrigerant flow direction and connects upstream of the evaporator, wherein the dehumidification line is connected between the second expansion valve and the evaporator, as taught by An et al., to improve the system of Park et al. by allowing for dehumidification and heating of the vehicle.
Regarding claim 10, Park et al. as modified by An et al. further discloses wherein the dehumidification line branches off between the indoor heat exchanger and the first expansion valve (see at least An et al. #BR2 branching off between expansion valve #1700 and indoor heat exchanger #1200), and includes a third expansion valve capable of controlling the refrigerant amount and expanding the refrigerant (see at least valve #2230).
Regarding claim 11, Park et al. as modified by An et al. further discloses wherein the dehumidification line branches off between the first expansion valve and the water-cooled condenser, and includes a shut-off valve controlling only the refrigerant amount (see at least An et al. line #BR2 branches off between expansion valve #1700 and water-cooled condenser #1300 and includes valve #2230).
Regarding claim 14, Park et al. as modified by An et al. further discloses wherein in a maximum heating and dehumidification mode, the refrigerant flow direction-changing valve opens only the inlet of the connection line downstream of the outdoor heat exchanger in the refrigerant flow direction and allows the refrigerant to pass through directly so that the refrigerant is controlled to sequentially circulate through the compressor, the indoor heat exchanger, the first expansion valve, the water-cooled condenser, the outdoor heat exchanger, the refrigerant flow direction- changing valve, the chiller, and the compressor, and a portion of the refrigerant passing through the indoor heat exchanger is supplied to the evaporator through the dehumidification line (see at least Park et al. Figure 2 as modified by An et al., there exists a mode such that an inlet of valve combination #2200/#2030 opens only an inlet such that refrigerant passes through compressor #1100, indoor heat exchanger #1200, expansion valve #2010, water-cooled condenser #1300, outdoor heat exchanger #1400, part of valve combination #2200, and through evaporator #1500 via line #BR2), and
wherein in a partial heating and dehumidification mode, the refrigerant flow direction-changing valve opens only the inlet of the branch line between the water-cooled condenser and the outdoor heat exchanger so that the refrigerant is controlled to sequentially circulate through the compressor, the indoor heat exchanger, the first expansion valve, the water-cooled condenser, the refrigerant flow direction-changing valve, the chiller, and the compressor, and a portion of the refrigerant passing through the indoor heat exchanger is supplied to the evaporator through the dehumidification line (see at least Park et al. Figure 2 as modified by An et al., there exists a mode such that an inlet of valve combination #2200/#2030 opens only an inlet such that refrigerant passes through compressor #1100, part of valve combination #2200/#2030, chiller #1700, compressor #1100 and to indoor heat exchanger #1200 through line #BR2).
