Office Action

§102
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 . Claim Rejections - 35 USC § 102 1. 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. 2. Claims 1-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US Patent 10,477,965 B1 (Chen ‘965). With respect to claim 1, Chen ‘965 shows a slide rail assembly (20), comprising: a first rail (28, Fig.3) arranged with a predetermined feature (40, Fig.3) and a blocking feature (50); a second rail (30, Fig.3) longitudinally movable relative to the first rail; a synchronization member (380, Fig.4), an engaging member (64b, Fig.4) and an auxiliary member (other end of 38 opposite 380, Fig.4) movably mounted on the second rail (30); and a third rail (34, Fig.3) longitudinally movable relative to the second rail (30) and arranged with a working feature (80); wherein during a process of the third rail (34) being moved along an opening direction (D1), the third rail (34) is configured to drive the second rail (30) to synchronously move by the working feature (80) abutting against the synchronization member (380) in a first state (380, FIg.7 “the synchronizing feature 80 is able to abut against an engaging section 380 of the synchronizing member 38 so as to make the second rail 30 and the third rail 34 moved synchronously in a first direction D1”; Col.7 lines 28-32); wherein during a process of the third rail (34) and the second rail (30) being synchronously moved along the opening direction (D1), the blocking feature (50) is configured to abut against the auxiliary member (other end of 38 opposite to 380, Fig.9) to move the auxiliary member from a first auxiliary position (Fig.7) to a second auxiliary position (Fig.9) relative to the second rail, in order to drive the synchronization member (380, Fig.9) to switch from the first state (Fig.7) to a second state (Fig.9), such that the working feature (80, Fig.7, FIg.9) of the third rail no longer abuts against the synchronization member (380, Fig.9), so as to unsynchronize movement between the third rail (34) and the second rail (30); wherein when the second rail (30) is located at an extended position relative to the first rail (28), the engaging member (64b, Fig.9) is configured to be engaged with the predetermined feature (40, Fig.9), in order to prevent the second rail (30) from being moved along a retracting direction (D2) from the extended position (“as to drive the third structure 64b of the positioning member 64 to abut against the first structure 40 of the first rail 28 to prevent the second rail 30 from being moved relative to the first rail 28 in a second direction D2”). With respect to claim 2, wherein the second rail (30) is movably mounted between the first rail (28) and the third rail (34). With respect to claim 3, wherein the auxiliary member (end of 38 opposite to 380, FIg.9) is longitudinally movable relative to the second rail (30). With respect to claim 4, wherein the auxiliary member and the second rail (30) respectively have a first limiting feature (protrusion) and a second limiting feature (H2, FIg.4) configured to interact with each other. With respect to claim 5, further comprising an elastic member (66, Fig.4) configured to provide an elastic force to the auxiliary member (“the elastic member 66 further comprises a section elastic section 66b configured to provide an elastic force to the synchronizing member 38” Col.5 lines 60-63). With respect to claim 6, wherein the elastic member (66b) is connected between the second rail (30) and the auxiliary member (38). With respect to claim 7, wherein the synchronization member (380) and the engaging member (64b) are pivotally connected to the second rail through a shaft member (68, Fig.4). With respect to claim 8, wherein the shaft member (68, FIg.4) is arranged in a direction substantially identical to a height direction of the second rail (30, Fig.4, Fig.5). With respect to claim 9, further comprising an elastic structure (66) configured to provide an elastic force to at least one of the synchronization member (380) and the engaging member (64b). With respect to claim 10, wherein the blocking feature (50, Fig.3) is a protrusion (Fig.3). With respect to claims 11-20, Chen ‘965 discloses the recited limitations as discussed above. 3. Claims 11-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US Patent 8,585,164 B2 (Chen ‘164). With respect to claim 11, Chen ‘164 shows a slide rail assembly, comprising: a first rail (10, Fig.1) arranged with a blocking feature (16, Fig.1); a second rail (12) longitudinally movable relative to the first rail (10); a synchronization member (50, at 60, Fig.2) movably mounted on the second rail; an auxiliary member (22 and 46, Fig.3) movable relative to the second rail between a first auxiliary position (Fig.3) and a second auxiliary position (Fig.4); and a third rail (14) longitudinally movable relative to the second rail (12) and arranged with a working feature (64, Fig.1); wherein during a process of the third rail (14) being moved along an opening direction, the third rail (14) is configured to drive the second rail (12) to synchronously move by the working feature (64) abutting against the synchronization member (50 at 60, Fig.5); wherein during a process of the third rail (14) and the second rail (12) being synchronously moved along the opening direction (Col.3 lines 44-50), the blocking feature (16) is configured to abut against the auxiliary member (at 46, Fig.4) to linearly move the auxiliary member from the first auxiliary position (Fig.3) to the second auxiliary position (Fig.4) relative to the second rail (12), in order to drive the synchronization member (50, at 60, FIg.3, Fig.4) to move, such that the working feature (64) of the third rail (14) no longer abuts against the synchronization member (50, see Fig.4), so as to unsynchronize movement between the third rail (14) and the second rail (12). With respect to claim 12, wherein the second rail (12) is movably mounted between the first rail (10) and the third rail (14, Fig.1). With respect to claim 13, wherein the auxiliary member (46 and 22) is movably mounted on the second rail (12, Fig.3, Fig.4). With respect to claim 14, wherein the auxiliary member (46 and 22) and the second rail (12) respectively have a first limiting feature (40, 28, Fig.1) and a second limiting feature (48, 46/26 and 28) configured to interact with each other. With respect to claim 15, further comprising an elastic member (44) configured to provide an elastic force to the auxiliary member. With respect to claim 16, wherein the elastic member (44) is connected between the second rail (12) and the auxiliary member (22, Fig.5). With respect to claim 17, wherein the synchronization member (50) is pivotally connected to the second rail (12) through a shaft member (62, FIg.2). With respect to claim 18, wherein the shaft member (62) is arranged in a direction substantially identical to a height direction of the second rail (12, Fig.2). With respect to claim 19, further comprising an elastic structure (52, Fig.2) configured to provide an elastic force to the synchronization member (50). With respect to claim 20, wherein the blocking feature (16) is a protrusion (Fig.1).
