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 (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 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 1-5, 8, 9, 12, 13 and 16-18 are rejected under 35 U.S.C. 103 as being unpatentable over Schoening “US 2019/0303848 A1” (Schoening) in view of Wetsch et al. “US 2017/0183139A” (Wetsch). Regarding Claims 1 and 16: A stock management system in a filling plant with at least one filling machine product, and a warehouse the system comprising: first tag elements provided on respective storing units designed for storage of a respective plurality of packaging material elements (at least See Schoening Abstract; Fig.1; [0036]-[0046]), each of the first tag elements including first stock information about the packaging material elements stored in the respective storing unit (at least See Schoening Abstract; [0045]-[0055]) the warehouse containing a stock of the packaging material elements for forming composite packages (at least See Schoening Abstract; [0022]-[0025]); a second tag element provided on each of the packaging material element (at least See Schoening [0036]-[0041]), the second tag clement including second stock information about related packaging material element (at least See Schoening Abstract; [0040]-[0044]); and a control system configured to: receive, by the control system operating data from the at least one filling machine relating to the-filling operations, the at least one filling machine configured to form the composite packages from a multilayer composite packaging material and to implement filling operations to fill the composite packages with a pourable food product, wherein the operating data are automatically logged by the at least one filling machine during packaging operations using a packaging material element identified by the second tag element (at least See Schoening Abstract; [0050]-[0060]; Note: “[0059] FIGS. 5-18 illustrate examples of information that may be shown on a display screen 50 of the user interface device 23 during this activity. Common elements between FIGS. 5-18 are shown using common reference numerals. In particular, FIGS. 5-10 illustrate examples of the information displayed to the forklift operator on a display screen 50 of the user interface device 23 when a product 13 in the storage and shipping environment 10 needs to be relocated to a particular bin 14 or delivered to a particular loading bay 16 and placed on a truck. FIGS. 5, 6, 7, 8, 9, and 10 illustrate a display screen 50C, 50D, 50E, 50F, 50G, and 50H, respectively, of the user interface device 23 displaying a product code 60, a roll number 62 (as in this case the product 13 is a roll of material), a current location 64 of a product 13, a destination 66 of the product 13, an RFID tag counter 68, a next roll input 70, a product information menu 72, and a relock-roll input 75.
