The refrigerator of claim 13, wherein a distance from the handle rotation shaft 331 to a lower end of the door handle is formed to be longer than a distance from the handle rotation shaft 331 to an upper end of the door handle (Fig. 7). The differences being that Park ‘608 fails to clearly disclose the limitations in claim 1 of wherein the door plate is made of a metal material and continuously bent to form the front part, the side part, and the rear part (instead of two parts 22 and 24). However, Kretschmer discloses a refrigerator 1 comprising: a cabinet 2 that has a storage space defined therein; a door 4 configured to open and close the storage space, the door 4 comprising (such as shown in Figs. 2-4) (i) a door plate that defines a front surface 3 of the door 4 and (ii) a door liner that defines a rear surface of the door 4; and a door opening device 7 provided on the door 4 and configured to be manipulated to open the door 4; wherein the door opening device 7 comprises: a door handle rotatably mounted and configured to be rotated by a user's manipulation, and a push slider 12, the push slider 12 being configured to reciprocate in a straight line according to rotation of the door handle and to push the cabinet 2 to open the door 4, and wherein the door plate comprises: a front part 3 that defines the front surface 3 of the door 4, a side part that is bent from the front part and defines a side surface 9 of the door 4, and a rear part (not numbered, but can be clearly seen in Figs. 2-4) that is bent from the side part 9 and defines a portion of the rear surface of the door, the rear part having a slider outlet through which the push slider 12 selectively protrudes to push the cabinet 1; wherein the door plate is made of a material continuously bent to form the front part, the side part, and the rear part. Therefore, it would have been obvious and well within the level of one skilled in the art before the effective filing date of the claimed invention, in view of Kretschmer, to modify Park ‘608 to include the limitations in Claim 1 of wherein the door plate is made of a metal material continuously bent to form the front part, the side part, and the rear part with a reasonable expectation of success in order reduce the number of parts of the refrigerator. Claim(s) 7 and 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park ‘608, as modified, as applied to claim 1 above, and further in view of CN 212299105 to Shi. Park ‘608, as modified, discloses all the elements as discussed above except for the limitations recited in the above listed claims. However, Shi discloses a home appliance comprising: a cabinet that has a storage space defined therein; a door 110 configured to open and close the storage space, the door comprising a door plate that defines a front surface of the door 110 and a door liner that defines a rear surface of the door; and a door opening device 120 provided on the door 110 and configured to be manipulated to open the door 110; wherein the door opening device comprises: a door handle 120 rotatably mounted inside the door 110 and configured to be rotated by a user’s manipulation; wherein the door plate comprises a front part that defines the front surface of the door 110, the front part having a plate opening through which the door handle is exposed; wherein, in a state where the door handle is not manipulated (such as shown in Fig. 3), a front surface of the door handle 120 shields the plate opening of the door plate and forms a same plane as the front surface of the door plate such that the front surface of the door handle 120 forms a substantially continuous surface with the front surface of the door plate, and wherein in a state where the door handle is manipulated (such as shown in Fig. 4), the door handle 120 protrudes from the front surface of the door plate for a user to grip and pull the door handle to open the door 110; wherein a pressing part 124 configured to rotate the door handle 120 by a user pressing the door handle 120 is formed on a front surface of the door handle 120 above a handle rotation shaft 130. Therefore, it would have been obvious and well within the level of one skilled in the art before the effective filing date of the claimed invention, in view of Shi, to modify Park ‘608, as modified, to include the limitations in Claim 7 of wherein, in a state where the door handle is not manipulated, a front surface of the door handle shields the plate opening of the door plate and forms a same plane as the front surface of the door plate such that the front surface of the door handle forms a substantially continuous surface with the front surface of the door plate, and wherein in a state where the door handle is manipulated, the door handle protrudes from the front surface of the door plate for a user to grip and pull the door handle to open the door; and Claim 15 of wherein a pressing part configured to rotate the door handle by a user pressing the door handle is formed on a front surface of the door handle above the handle rotation shaft with a reasonable expectation of success in order to improve overall appearance of the refrigerator.

Park ‘608, as modified, discloses all the elements as discussed above including the limitations in claim 18 of wherein the case comprises a spring mounting part 318 (Figs. 8-9) protruding through the spring 35. The difference being that Park ‘608 fails to clearly disclose wherein the horizontal part defines a guide hole that is opened to pass through the spring mounting part and configured to guide movement of the push slider in a front-rear direction. However, Lim discloses a refrigerator comprising: a cabinet 10 that has a storage space defined therein; a door 20 configured to open and close the storage space; and a door opening device provided on the door 20 and configured to be manipulated to open the door 20, wherein the door opening device comprises: a case that is provided inside the door 20 and defines an accommodation space, a door handle rotatably mounted inside the case and configured to be rotated by a user's manipulation, and a push slider 40 accommodated in the case, the push slider 40 being configured to reciprocate in a straight line according to rotation of the door handle and to push the cabinet 10 to open the door 20; wherein the case comprises: a handle accommodation part which is opened toward a plate opening and in which the door handle is accommodated; and a slider accommodation part configured to communicate with the handle accommodation part, open toward the side part, and extend to a rear surface of the door 20, to accommodate the push slider 40; wherein the push slider 40 comprises: a horizontal part 44 accommodated in the case and in contact with an upper rear end of the door handle; and a vertical part 42 extending vertically rearward from an end portion of the horizontal part and in contact with the cabinet through a slider outlet; wherein the case is provided with a spring 50 configured to support the horizontal part 44 from a rear side of the horizontal part 44, and wherein the spring 50 is configured to be compressed based on the push slider 40 moving rearward; wherein the case comprises a spring mounting part 28 protruding through the spring 50, and wherein the horizontal part 44 defines a guide hole 43 (such as shown in Fig. 3) that is opened to pass through the spring mounting part 28 and configured to guide movement of the push slide 40 in a front-rear direction. Therefore, it would have been obvious and well within the level of one skilled in the art before the effective filing date of the claimed invention, in view of Lim, to modify Park ‘608, as modified, to include the limitations in Claim 18 of wherein the horizontal part defines a guide hole that is opened to pass through the spring mounting part and configured to guide movement of the push slider in a front-rear direction with a reasonable expectation of success in order to prevent nonuniform contraction and restoration of the elastic member and to increase the overall versatility of the refrigerator. Claim(s) 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park ‘608, as modified, as applied to claim 1 above, and further in view of 2019/0024965 to Park (hereinafter Park ‘965). Park ‘608, as modified, discloses all the elements as discussed above except for the limitations recited in claim 21. However, Park ‘965 discloses a refrigerator 3,4 comprising (such as shown in Figs. 14-15): a cabinet 30,40 that has a storage space defined therein; a door (Fig. 14: 34,35; Fig. 15: 45) configured to open and close the storage space; and a door opening device provided on the door and configured to be manipulated to open the door, wherein the door opening device can be used on (i) a cabinet comprises (Fig. 14): a barrier 31 that partitions the storage space into a left storage space 33 and a right storage space 32, wherein the door is configured to open and close the left or right storage space by rotation, and wherein a push slider is configured to protrude toward the barrier 31; or (ii) a cabinet comprises (Fig. 15): a barrier 41 that partitions the storage space into an upper storage space and a lower storage space. Therefore, it would have been obvious and well within the level of one skilled in the art before the effective filing date of the claimed invention, in view of Park ‘965, to modify Park ‘608, as modified, to include the limitations in Claim 21 of wherein the cabinet comprises a barrier that partitions the storage space into a left storage space and a right storage space, wherein the door is configured to open and close the left or right storage space by rotation, and wherein the push slider is configured to protrude toward the barrier with a reasonable expectation of success in order to increase the overall versatility of the refrigerator. Response to Arguments Applicant's arguments filed 3/4/2026 have been fully considered but they are not persuasive. In response to applicant’s arguments on page 8 that (i) the cap 24 of Park ‘608 is not made of a metal material as claimed, but rather is made of a plastic material, and (ii) the outer case 22 and the cap 24 are separate parts, and thus fails to meet the claimed limitations of the door plate is continuously bent to form a front part, a side part, and a rear part, the examiner respectfully take the position that (a) claim 1 is being rejected under 35 U.S.C. 103 in view of Kretschmer; therefore, Park ‘608 is not required to disclose all the elements of the door plate is made of a metal material and continuously bent to form a front part, a side part, and a rear part; (b) Park ‘608 discloses the outer case/front plate 22 being made of a metal material, and Kretschmer teaches the idea of a refrigerator door plate being continuously bent to form a front part, a side part, and a rear part. Therefore, it would have been obvious and well within the level of one skilled in the art before the effective filing date of the claimed invention, in view of Kretschmer, to modify Park ‘608 to include the limitations in Claim 1 of wherein the door plate is made of a metal material continuously bent to form the front part, the side part, and the rear part with a reasonable expectation of success in order reduce the number of parts of the refrigerator. Further, US 2019/0024965 to Park also shows that it is well known in the art to provide a door having a door plate 100 being made of a metal material ([0064]) and continuously bent to form: a front part that defines a front surface of the door, a side part that is bent from the front part and defines a side surface of the door, and a rear part that is bent from the side part (such as shown in Figs. 3-4 & 10-15). In response to applicant’s argument on page 8, second full paragraph that there is no teaching, suggestion, or motivation to combine the references, the examiner recognizes that obviousness may be established by combining or modifying the teachings of the prior art to produce the claimed invention where there is some teaching, suggestion, or motivation to do so found either in the references themselves or in the knowledge generally available to one of ordinary skill in the art. See In re Fine, 837 F.2d 1071, 5 USPQ2d 1596 (Fed. Cir. 1988), In re Jones, 958 F.2d 347, 21 USPQ2d 1941 (Fed. Cir. 1992), and KSR International Co. v. Teleflex, Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007). In this case, the motivation to do so is in order reduce the number of parts of the refrigerator. In response to applicant’s argument on pages 8-9 regarding Kretschmer, the examiner respectfully take the position that Kretschmer is used only for the teaching that it is well known in the art to provide a door plate being continuously bent to form: a front part, a side part, and a rear part. Therefore, Kretschmer is not required to disclose the door plate is made of a metal material, the front part having a plate opening, and the rear part having a slider outlet.
