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 .
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)(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 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Williamson et al. (US 2010/0038926).
With respect to claim 1, Williamson et al. disclose a locking device, configured to be engaged with a carriage, comprising:
a locking block 86 capable of abutting against the carriage 24 (as shown in Fig. 1 of Williamson et al.);
a handle 80 slidably disposed in the locking block 86 (as shown in Figs. 6A-6B of Williamson et al.); and
a locking component 94 disposed on the handle 80 and capable of being engaged in a positioning recess 90 of the locking block 86, wherein when the locking component 94 is engaged in the positioning recess 90, the locking component restricts relative movement between the locking block 86 and the handle 80 (Williamson et al., paragraph [0049]; Fig. 6B).
Claim Rejections - 35 USC § 103
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.
Claims 1-8 and 10-17 are rejected under 35 U.S.C. 103 as being unpatentable over Shen et al. (US 2022/0203813) in view of Chen (US 5,295,717).
With respect to claim 1, disclose Shen et al. disclose the claimed locking device except for the locking component disposed on the handle and capable of being engaged in a positioning recess of the locking block. Shen et al. disclose a locking device, configured to be engaged with a carriage, comprising:

a handle 5 slidably disposed in the locking block 4 (as shown in Figs. 4B and 4C of Shen et al.).
Chen teaches a similar locking device including a locking block 25, a handle 40, and a locking component 51 disposed on the handle 40 and capable of being engaged in a positioning recess 26 of the locking block 25 (as shown in Fig. 5 of Chen), wherein when the locking component 51 is engaged in the positioning recess 26, the locking component restricts relative movement between the locking block 25 and the handle 40 (Chen, col. 5, lines 4-16; Fig. 10).
It 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, with a reasonable expectation of success, to combine the teaching of Chen with the locking device disclosed by Shen et al. for the advantage of preventing the handle from easily opening due to movement and vibration of the locking device.
With respect to claim 2, Chen teaches that the locking component 51 comprises a positioning member 53 and a guide frame, the guide frame is disposed on the handle 40 as shown below in the image taken from Fig. 10 of Chen:

a carriage cover body (Shen et al., paragraph [0005]),
a first mounting strip 8,
a second mounting strip 1, and
the locking device according to claim 1 (as outlined above in the prior art rejection of claim 1), wherein the first mounting strip and the second mounting strip are perpendicular to each other and are disposed on a lower side of the carriage cover body (as shown in Figs. 3 and 4B of Shen et al.), the locking device is disposed on the second mounting strip 1 (as shown in Fig. 4B of Shen et al.), and when the carriage cover covers the carriage, the locking device is configured to be engaged with the carriage 10 (Shen et al., paragraphs [0004]-[0005]).

Claims 1, 9, 10, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Zheng (US 11,014,436) in view of Chen (US 5,295,717).
With respect to claim 1, disclose Zheng discloses the claimed locking device except for the locking component disposed on the handle and capable of being engaged in a positioning recess of the locking block. Zheng discloses a locking device, configured to be engaged with a carriage, comprising:
a locking block 338 capable of abutting against the carriage 22 (as shown in Fig. 3 of Zheng); and
a handle 340 slidably disposed in the locking block 338 (Zheng, col. 9, lines 20-27).
Chen teaches a similar locking device including a locking block 25, a handle 40, and a locking component 51 disposed on the handle 40 and capable of being engaged in a positioning recess 26 of the locking block 25 (as shown in Fig. 5 of Chen), wherein when the locking component 51 is engaged in the positioning recess 26, the locking component restricts relative movement between the locking block 25 and the handle 40 (Chen, col. 5, lines 4-16; Fig. 10).
It 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, with a reasonable expectation of success, to combine the teaching of Chen with the locking device disclosed by Zheng et al. for the advantage of preventing the handle from easily opening due to movement and vibration of the locking device.
