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 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 of this title, 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. Alternatively, Claims 1-5 and 12 are rejected under 35 U.S.C 103(a) as being unpatentable over WO 2022030835 (“Lee et al.”) in view of 20100109497 (“Blersch et al.”). Regarding Claim 1, Lee et al. discloses a refrigerator comprising: a cabinet (10) having a storage space; a door (20) configured to open and close the cabinet (10); a hinge bracket configured to connect the door (20) to the cabinet (10) to rotatably support the door (20); an auto-closing device (40) configured to provide a closing force to the door (20) to assist in rotating the door (20) towards a closed position, the auto-closing device (40) being in contact with the hinge bracket during a portion of a rotation of the door (20); the auto-closing device comprising a lever (420) configured to be rotatable about a position that is spaced apart from a rotation center of the door, and the auto-closing device provides a closing force to the door. Lee et al. discloses the surfaces 324 and 325 provide a restrictive force to the lever but not expressly disclose a damping mechanism that provides a damping force to the lever. Blersch et al. discloses a similar invention mounted on a refrigerator door (10), the auto closing device (155, 120, 140) is configured to provide a closing force to the door and damping mechanism (200) configured to provide damping force to the lever (155) while the auto-closing device provides the closing force to the door (10). It would have been obvious to one having skill in the art before the effective filing date of the invention that that auto closing device could be improved with a damping device similar to the one taught by Blersch et al. to provide a damping force on the lever to slow the door closing, as is well known in the art. Regarding Claim 2, the combination discloses (Lee et al.) wherein the auto-closing device (40) comprises an elastic member (450) connected to the lever (420) or wherein the damping mechanism is located on the door. Regaring Claims 3-5, the combination discloses (Blersch et al.) Claim 3- wherein the damping mechanism (200) comprises a damper (best seen in Fig.4) configured to be in contact with the lever(155); Claim 4-wherein the damping mechanism (200) further comprises a fixing bracket (300) to couple the damping mechanism to the door (10) at one side of the auto-closing device (155) ; Claim 5 -the damper (200) comprise: a fixed member (202) ; and a movable member (204) configured to move relative to the fixed member (202), the movable member being connected to the lever (155, via support shown in Fig. 4) or in contact with one surface of the lever (155). Regarding Claim 12, The combination discloses (Lee et al.) wherein, when the lever (420) moves in a first direction while the door (20) is being closed, the movable member of the damper moves from a first position to a second position, and wherein, when the lever (420) moves in a second direction opposite the first direction while the door (20) continues to be moved to the closed position, the movable member of the damper is configured to provide the damping force to the door (20) while moving from the second position to the first position, as modified by Blersch et al. Claims 13-18, as best understood, are rejected under 35 U.S.C 103(a) as being unpatentable over Lee et al. and Blersch et al. as applied to claim 1 above, and further in view of WO 2019/172592 ("Kim et al."). The combination discloses Claim 13- Lee et al. wherein the auto-closing device (40) comprises: a lever (420) configured to be rotatable about a position that is spaced apart from a rotation center of the door; an elastic member (450)connected to the lever ; and a case (410) configured to accommodate the elastic member therein, the claimed invention but does not disclose the damper mechanism in the case with the elastic member. Regarding Claim 13, Kim et al. demonstrates it is known in the art to provide and elastic member(33) in a case (10) with a damping mechanism (31, 32, 14, 40). It would have been obvious to one having skill in the art before the effective filing date of the invention that that the case taught by Lee et al. could be modified to house both the spring and damping mechanism, in a manner similar to the elastic and damper mechanism taught Kim et al. so that the door opens and closes slowly. Claim 14, the combination discloses (Kim et al.) wherein the damping mechanism (31, 32) comprises: a first member (32) connected to the lever ; and a second member (31) configured to be movable with respect to the first member (32) such that, when the first member rotates (32), the second member (31) moves linearly, (in the same manner as the original case taught by Lee et al). Regarding Claim 15, the combination discloses (Kim et al.) wherein a rotation center of the first member (32) is the same as a rotation center of the lever . Regarding Claim 16, the combination discloses (Kim et al.) wherein the damping mechanism further comprises an elastic member (33) configured to elastically support the second member (31). Regarding Claim 17, The combination discloses (Kim et al.) wherein the first member comprises a first space configured to accommodate oil (14) therein, wherein the second member comprises a second space configured to accommodate oil therein, and wherein the damping mechanism includes a buffer space configured to accommodate oil therein, the buffer space being located between the case and the second member (as seen in Figs. 3-7). Regarding Claim 18, The combination discloses (Kim et al.) wherein the first (32) member comprises a first uneven portion, and wherein the second member (31) comprises a second uneven portion that is engaged with the first uneven portion according to a rotational position of the first member (as seen in Figs. 3-7). Response to Arguments Applicant’s arguments with respect to claims 1-18 have been considered but are moot because the arguments do not apply to any of the references as applied in the current rejection. Allowable Subject Matter Claims 19-20 would be allowable if rewritten 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. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
