It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the teachings of Yuichi in view of Hyun, Sakamoto, and Yoshioka which include an article transport facility comprising travel routes, storage locations, and carry-in/out sections with the storage unit spanning multiple vertical levels as taught by Otsuka to provide additional storage capacity and routes in an article transport facility. Before the effective filing date, a person of ordinary skill in the art would have been motivated to have modified said article transport facility teachings with a storage unit system spanning multiple vertical levels to increase throughput of the transport system while maintaining the same horizontal footprint and potentially reduce distance between sections, with a reasonable expectation of success. Regarding Claim 8 , Yuichi in view of Hyun, Sakamoto, and Yoshioka describes an article transport facility comprising travel routes, storage units, and carry-in/out sections, as well as a transport vehicle used therein across storage levels , but does not describe the transport vehicle traveling between storage levels that are arranged adjacent to each other in the vertical directions. However, Otsuka teaches a plurality of storage levels arranged vertically, with route width oriented adjacent rows, that said transport vehicle operates in. the transport vehicle comprises: a holding section configured to hold the article in a suspended orientation [See at least Yuichi: Para. 0024-0030 "The carriage 1 also includes a container holding portion 14" ]; and an elevating device configured to raise and lower the holding section [See at least Yuichi: 0024-0030 "The elevating portion 16 is configured to be able to raise and lower the container holding portion 14" ], the elevating device lowers the holding section from above toward the carry-in section and the carry-out section to transfer the article to and from the carry-in section and the carry-out section [See at least [See at least Yuichi: 0024-0030 "The elevating portion 16 is configured to be able to raise and lower the container holding portion 14" , and at least Sakamoto: Col. 4, line 33 to Col. 5, line 19 "a container 1 stored at a storage section 6 is transported from the storage section 6 to an inside location 9 of a carry-in-and-out transport device 4 by the raising-and-lowering transport device 2" ] , one of the plurality of storage levels is a first storage level, another of the plurality of storage levels is a second storage level, the carry-in section in the first storage level is a first carry-in section, the carry-out section in the first storage level is a first carry-out section, the carry-in section in the second storage level is a second carry-in section, and the carry-out section in the second storage level is a second carry-out section [See at least Sakamoto: Col. 8, lines 35-52 "The storage sections or locations 6 are arranged such that a plurality of storage sections 6 form multiple vertical levels along the vertical direction X...in each vertical level for which one or more carry-in-and-out transport devices 4 are provided" and Fig. 1 , Ref. Numeral 4 of “ U ” , “ M ” , and “ D ” , and at least Otsuka: Col. 7, lines 14-35 ] , the first carry-in section overlaps one of the second carry-in section and the second carry-out section in the vertical view, and the first carry-out section overlaps the other of the second carry-in section and the second carry-out section in the vertical view [See at least Sakamoto: Col. 8, lines 35-52 "The storage sections or locations 6 are arranged such that a plurality of storage sections 6 form multiple vertical levels along the vertical direction X...in each vertical level for which one or more carry-in-and-out transport devices 4 are provided" and Fig. 1 , Ref. Numeral 4 of “ U ” , “ M ” , and “ D ” , and at least Otsuka: Col. 7, lines 14-35 ] , and the first carry-in section, the first carry-out section, the second carry-in section, and the second carry-out section protrude and retract in a horizontal direction independently of each other [See at least Sakamoto: Col. 4, lines 49-61] . It would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the teachings of Yuichi in view of Hyun, Sakamoto, and Yoshioka for an article transport facility with associated limitations including a transport vehicle that can travel between storage levels with the teachings of Otsuka to allow the transport device to move between storage levels that are arranged vertically adjacent to each other and with rows that are horizontally adjacent. Before the effective filing date, a person of ordinary skill in the art would have been motivated to modify the article transport facility and transport vehicle used therein with the vertically adjacent storage and horizontally adjacent rows to reduce overall facility footprint and increase throughput and efficiency, with a reasonable expectation of success. Claim(s) FILLIN "Insert the claim numbers which are under rejection." \d "[ 1 ]" 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over FILLIN "Insert the prior art relied upon." \d "[ primary prior art reference name and number ]" Yuichi et al.
