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, 3-5, 7-16 and 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over Valberg (US 2022/0187927 A1) in view of Prejer (US 2016/0161989 A1). Regarding claim 1, Valberg discloses a control unit for an agricultural working machine (see e.g. at least Abstract, Fig. 1, 4, and related text), the control unit comprising: a housing that has a front side, a rear side, and end faces (see e.g. at least Fig. 4, and related text), wherein the housing has on the front side a plurality of control elements (e.g. at least fixed control actuator 11, pre-coded push buttons 1, see e.g. at least ¶ 53, 56, Fig. 4, and related text) as well as a display (e.g. at least touch screen of device 6, see e.g. at least ¶ 61, Fig. 4, and related text), wherein control elements are arranged on one side of a straight line extending along an edge of the display in a plan view of the front side (see e.g. at least Fig. 4, and related text). Additionally, Prejer teaches limitations not expressly disclosed by Valberg including namely: [a housing that has a front side, a rear side, and end faces] that connect the front side and the rear side to one another (see e.g. at least Fig. 1, 4, 9, and related text, illustrating perspective views from the front, back, and sides of a tablet computer configured in an enclosed housing). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the teaching of Valberg by configuring [a housing that has a front side, a rear side, and end faces] that connect the front side and the rear side to one another as taught by Prejer in order to ensure protection for otherwise fragile electronic control devices in harsh working environments (Prejer: ¶ 10). Regarding claim 3, Modified Valberg teaches that an extent of the housing in a longitudinal direction of the display is greater than an extent of the housing in a transverse direction of the display (Valberg: see e.g. at least Fig. 4, and related text; Prejer: see e.g. at least Fig. 1, and related text). Regarding claim 4, Modified Valberg teaches that a width-to-length ratio of the display is in a range of 1:3 + 15% to 1:4 - 15% (Valberg: see e.g. at least Fig. 4, and related text; Prejer: see e.g. at least Fig. 1, and related text). Regarding claim 5, Modified Valberg teaches that control elements comprise at least one button, switch, at least one joystick and/or at least one rotary knob (Valberg: see e.g. at least Fig. 4, and related text; Prejer: see e.g. at least Fig. 1, and related text). Regarding claim 7, Modified Valberg teaches that the housing has a recessed grip and/or grip bulge on the rear side of a part containing control elements (Prejer: see e.g. at least Fig. 3-4, and related text). Regarding claim 8, Modified Valberg teaches that the display is touch-insensitive (Prejer: see e.g. at least ¶ 15, Fig. 1, and related text). Regarding claim 9, Modified Valberg teaches that the display is angled towards a part of the front side containing control elements (Prejer: see e.g. at least Fig. 6, and related text). Regarding claim 10, Modified Valberg teaches that the control unit is an ISOBUS control unit (Valberg: see e.g. at least ¶ 2). Regarding claim 11, Modified Valberg teaches that the control unit operates multiple parts of an agricultural machine or multiple parts of different agricultural machines (Valberg: see e.g. at least ¶ 4; Prejer: see e.g. at least ¶ 18, 30, 36). Regarding claim 12, Modified Valberg teaches an impact switch (Valberg: see e.g. at least ¶ 56, Fig. 3a-4, and related text). Regarding claim 13, Modified Valberg teaches that the control unit adjusts the display representation depending on an orientation of the control unit (Valberg: see e.g. at least ¶ 61, Fig. 1, and related text, teaching that the handheld device 6 may be an android handheld computer or an iPad). Regarding claim 14, Modified Valberg teaches that the housing has a multi-part design and includes an insert that comprises control elements present on the front side (Valberg: see e.g. at least ¶ 4; Prejer: see e.g. at least Fig. 1, 5-9, and related text). Regarding claim 15, Modified Valberg teaches an agricultural machine comprising a control unit as claimed in claim 1 (see rejection of claim 1 above; see also e.g. at least Valberg: see e.g. at least Abstract, ¶ 8; Prejer: see e.g. at least Abstract, ¶ 18). Regarding claim 16, Modified Valberg teaches that the plurality of control elements are arranged at least partially in rows (Valberg: see e.g. at least Fig. 4, and related text; Prejer: see e.g. at least Fig. 1, and related text). Regarding claim 18, Modified Valberg teaches that the ISOBUS control unit is an ISOBUS-AUX-N control unit (Valberg: see e.g. at least ¶ 2). Regarding claim 19, Modified Valberg teaches that the impact switch is housed on an end face of the housing (Valberg: see e.g. at least ¶ 56, Fig. 3a-4, and related text). Regarding claim 20, Modified Valberg teaches that the control unit includes a gyroscope [intended for detecting the orientation of the control unit and is [intended to automatically adjust an assignment of control elements depending on the orientation]] (Valberg: see e.g. at least ¶ 61, Fig. 1, and related text, teaching that the handheld device 6 may be an android handheld computer or an iPad). Claims 2 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Valberg (US 2022/0187927 A1) in view of Prejer (US 2016/0161989 A1) as applied to claim 1 above, and further in view of Marcello (EP 1714822 A1). Regarding claim 2, Marcello teaches limitations not expressly disclosed by Valberg including namely: that the straight line extends along a longitudinal edge of the display (see e.g. at least Fig. 2, illustrating a control unit including a display oriented in landscape view with control elements configured below the display). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the teaching of Valberg by configuring teaches that the straight line extends along a longitudinal edge of the display as taught by Marcello in order to configure many individually useful control elements around a display screen in an uncrowded and ergonomically efficient layout, enabling display elements on the display screen to be controlled in an easy and intuitive manner (Marcello: ¶ 8, 11, 13, 33). Regarding claim 17, Marcello teaches limitations not expressly disclosed by Valberg including namely: the switch is at least one toggle switch, and the at least one rotary knob is a rotary push knob (see e.g. at least ¶ 26, 28, 51, 78). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the teaching of Valberg by configuring teaches that the straight line extends along a longitudinal edge of the display as taught by Marcello in order to configure many individually useful control elements around a display screen in an uncrowded and ergonomically efficient layout, enabling display elements on the display screen to be controlled in an easy and intuitive manner (Marcello: ¶ 8, 11, 13, 33). Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Valberg (US 2022/0187927 A1) in view of Prejer (US 2016/0161989 A1) as applied to claim 1 above, and further in view of Ehrl (US 2012/0229394 A1). Regarding claim 6, Ehrl teaches limitations not expressly disclosed by Valberg including namely: that control elements comprise rotary knobs arranged on end faces that face away from one another (see e.g. at least Fig. 1a-1b, and related text). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the teaching of Valberg by configuring that control elements comprise rotary knobs arranged on end faces that face away from one another as taught by Ehrl in order to provide the operator with flexibility when working with dirty hands or traveling over rough or uneven ground and allow quick screen adjustment and selection of values in an intuitive and flexible manner using either of the operator’s thumbs (Ehrl: ¶ 7-8, 40).
