Office Action

§102
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The Information disclosure statement of 05/30/2024 has been received and reviewed. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-11 and 15-20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 5931514 to Chung. Regarding claim 1, Chung discloses: A detachable device (fig 1) comprising: a base (1); an object (2) detachably disposed over the base and comprising a fastening part (10); and a latching structure (8,9) for detachably connecting the base and the object, the latching structure comprising: a main body (8) disposed on the base with a distance (fig 1) from the base, the main body comprising: a buckle part (15) for detachably buckling with the fastening part of the object; and a release part (7) connected to the buckle part and arranged on a side (top side) of the buckle part away from the fastening part (fig 1); wherein, when being pushed by an external force, the release part drives the buckle part away from the fastening part to detach the object from the base (see dotted lines in fig 3). Regarding claim 2, Chung discloses: The detachable device according to claim 1, wherein the latching structure further comprises a bracket (5) mounted on a bearing surface (top surface of 1 seen in fig 1) of the base, and the bracket comprises: two mounting parts (right and left 5s) spaced apart on the bearing surface (fig 1); and a supporting part (6) disposed perpendicular to and between two top ends of the two mounting parts (fig 1); wherein the main body is disposed on and hanging from the supporting part and is spaced the distance apart from the bearing surface (fig 1). Regarding claim 3, Chung discloses: The detachable device according to claim 2, wherein the main body further comprises: a movable part (bottom portion of 7), wherein one end (top end) of the movable part is disposed on and hanging from the supporting part, and another end (bottom end) of the movable part is connected between the buckle part and the release part (figs 1 and 2). Regarding claim 4, Chung discloses: The detachable device according to claim 3, wherein the release part comprises: a push surface (surface of 7 that is abutted by 16 in fig 3) facing the fastening part. Regarding claim 5, Chung discloses: The detachable device according to claim 4, wherein, when the push surface of the release part is pushed by the external force, the movable part bends elastically and drives the buckle part to move (fig 3). Regarding claim 6, Chung discloses: The detachable device according to claim 4, wherein an end (bottom surface) of the push surface close to the base is a slanted surface (fig 3). Regarding claim 7, Chung discloses: The detachable device according to claim 2, wherein the bracket and the main body are integrally formed (fig 1). Claim 8 is rejected as per the rejection of claim 1 above (with the disassembling tool force being the external force in claim 1). Claim 9 is rejected as per the rejection of claims 2-4 above. Regarding claim 10, Chung discloses: The detachable device set according to claim 9, wherein, when the push surface of the release part is pushed by the disassembling tool, (16) the movable part bends elastically and drives the buckle part to move (fig 3). Regarding claim 11, Chung discloses: The detachable device set according to claim 10, wherein the disassembling tool comprises: a disassembling member (tip of 16) disposed on a flat surface (head of screwdriver 16) of the disassembling tool for pushing the push surface (fig 3). Regarding claim 15, Chung discloses: The detachable device set according to claim 11, wherein the disassembling member comprises: a protrusion (head of 16) for detachably abutting the release part (16 can attach to 7 when pushing against it, and then removed when not in use). Regarding claim 16, Chung discloses: A latching structure (8,9) comprising: a main body (8) disposed on a base (1) with a distance from the base (fig 1), the main body comprising: a buckle part (15) for buckling with a fastening part (10) of an object (2); a release part (7) connected to the buckle part; and a movable part (bottom of 7) disposed between the buckle part and the release part (fig 3); wherein, when being pushed by an external force (16), the release part drives the movable part to bend elastically to drive the buckle part away from the fastening part and be detached from the object (fig 3). Regarding claim 17, Chung discloses: The latching structure according to claim 16, further comprising: a bracket (5) mounted on a bearing surface (top surface of 1 seen in fig 1) of the base and comprising: two mounting parts (right and left 5s) spaced apart on the bearing surface; and a supporting part (6) disposed perpendicular to and between two top ends of the two mounting parts; wherein one end (top end) of the movable part is disposed on and hanging from the supporting part (fig 1), another end of the movable part is connected between the buckle part and the release part, and the main body and the bearing surface are spaced the distance apart (fig 1). Regarding claim 18, Chung discloses: The latching structure according to claim 17, wherein the release part comprises: a push surface (surface of 7 that is abutted by 16 in fig 3) facing the fastening part. Regarding claim 19, Chung discloses: The latching structure according to claim 18, wherein one end (bottom end) of the push surface close to the base is a slanted surface (fig 3). Regarding claim 20, Chung discloses: The latching structure according to claim 17, wherein the bracket and the main body are integrally formed (fig 1).
