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) 1, 3, 8, 10, 14 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kim 20210319947 in view of Park 6186603. As to claim 1, Kim discloses a coil assembly (120) of a solenoid valve (20) disposed in a bore (within 10) of a hydraulic block (10) having inlet flow (shown within side of 10 in Figure 2) and outlet flow paths (shown within bottom of 10 in Figure 2), the coil assembly comprising: a bobbin (110) having a through hole defined by an inner surface of the bobbin, the bobbin including a winding portion around which a coil is wound ([0047]); the coil wound around the winding portion of the bobbin to generate a magnetic force according to an electrical signal (via 50-130); a case (140), wherein at least a part of the bobbin is disposed inside the case; and a first heat transfer material ([0050]-[0051]) disposed between the top of hydraulic block (10) and the case (140) in which at least a part of the bobbin is disposed. However, Kim doesn’t explicitly disclose the material between a recessed portion formed at an end of the bore of the block and the case as recited.
Park discloses a coil assembly (7a) of a solenoid valve (7) disposed in a bore (within 31) of a hydraulic block (31) and shows that it is well known in the art to provide a heat transfer material (50) disposed between a recessed portion formed at an end of the bore of the hydraulic block (multiple bores within 31 as shown in Figure 2) and a case (18) in which the coil assembly is disposed.
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to provide the heat transfer material in Kim between a recessed portion formed at end of block bore and bobbin case in view of Park to disperse heat generated from the solenoid valves effectively, thereby preventing damage of the coils during operation of assembly.
As to claim 3, Kim discloses wherein the bobbin has a metal material ([0054]).
