Regarding claim 17, (See Modified Figure 2 above) wherein a first inner surface of the first folding plate (7) and a second inner surface of the second folding plate (8) are used for shielding oil dropped on the first inner surface and the second inner surface. Examiner note: the first inner surface of the first folding plate (7) and the second inner surface of the second folding plate (8) are depicted as being uniform sheets that are not foraminous and heat-resistant, thus they would be capable of shielding oil dropped on their respective surfaces. Regarding claim 20, (See Modified Figure 3 above) wherein in the close mode (Modified Figure 3), the first folding plate (7) and the second folding plate (8) are stacked one another. Konishi does not teach: Regarding claim 1, and a first heater placed in the first middle part to emit heat toward the grill bracket. Regarding claim 2, further comprising a second heater placed in the second middle part to emit heat toward the grill bracket. Regarding claim 3, wherein a first mesh is placed upon the first heater and a second mesh is placed upon the second heater for heat of the first heater and the second heater to emit heat passing through the first mesh and the second mesh toward the grill bracket. Scherer’s Figures 1 and 11 teaches: Regarding claim 1, (See Modified Figure 7 and Scherer’s Figures 1 and 11 above) a first heater (25) placed in the first middle part (Modified Figure 7) to emit heat toward the grill bracket (30 in Figure 11). Regarding claim 2, (See Modified Figure 7 and Scherer’s Figures 1 and 11 above) further comprising a second heater (25) placed in the second middle part (Modified Figure 7) to emit heat toward the grill bracket (30 in Figure 11). Regarding claim 3, (See Modified Figure 7 and Scherer’s Figures 1 and 11 above) wherein a first mesh (33 and Figure 7) is placed upon the first heater (25) and a second mesh (33) is placed upon the second heater (25) for heat of the first heater (25) and the second heater (25) to emit heat passing through the first mesh (33 and Figure 7) and the second mesh (33) toward the grill bracket (30 in Figure 11). Regarding claim 1, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Konishi to incorporate the teachings of Scherer’s Figures 1 and 11 to have a first heater placed in the first middle part to emit heat toward the grill bracket. Doing so limits the user’s ability to come into contact with the first heater, which prevents severe burns from occurring. The location of the first heater is perpendicular and in the first folding plate, which is away from the main points of user interface, such as the grill bracket and grill lever, where the food is placed. Regarding claim 2, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Konishi to incorporate the teachings of Scherer’s Figures 1 and 11 to have a second heater placed in the second middle part to emit heat towards the grill bracket. Doing so allows for symmetry of the heaters. The symmetry of the heaters is desirable because it allows for even heating of the food being cooked by the apparatus. Even heating of food is desirable to ensure the user does not become ill from consuming raw food. Regarding claim 3, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Konishi to incorporate the teachings of Scherer’s Figures 1 and 11 to have a first mesh and second placed on the first heater and second heater, respectively, to allow heat to pass through towards the grill bracket. Doing so helps to prevent users getting severe burns by preventing direct contact with the heaters, while still allowing for the flow of the heat from the heater to pass through towards the food. PNG media_image10.png 530 431 media_image10.png Greyscale Figure 15 (Scherer) Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Konishi in view of Scherer’s Figures 1 and 11 as applied to claims 1-3, 6, 7, 9, 10, 12, 13, 15-17, and 20 above, and further in view of Scherer’s Figure 15 (U.S. Patent Document No. 3358585). Konishi in view of Scherer’s Figures 1 and 11 teaches: Regarding claim 4, (See Modified Figure 7 and Figures 1 and 11 above) wherein the first heater (25) and the second heater (25) burn a combustible material or substance. “The construction of the heating units 25 is such that each functions to provide an individual heating chamber in which to confine and burn a combustible material or substance, such as charcoal, wood chips or other like combustible material, suitable for providing a source of heat for cooking purposes” (Pg. 6, Col. 5, Lines 16-21, Scherer). Konishi in view of Scherer’s Figures 1 and 11 does not teach: Regarding claim 4, wherein the first heater and the second heater receives electrical power to generate heat. Scherer’s Figure 15 teaches: Regarding claim 4, (See Figure 15 above) wherein the first heater (50) and the second heater (50) receives electrical power to generate heat. “In the foregoing embodiment, the heating units 25 are particularly designed to accommodate charcoal, wood chips and similar combustible materials for the generation of the heat used in the cooking and heating of various food items on the grill assembly. By contrast, a modified form of the heating units is shown and represented by the electric heating unit 50” (Pg. 7, Col. 7, Lines 23-29). Regarding claim 4, it would have been obvious to one of ordinary skill in the art before the effective filing date to substitute the Konishi in view of Scherer’s Figures 1 and 11’s combustible heater (see Scherer’s Figure 1 and 11 and Modified Figure 7 (25)) with the Scherer’s Figure 15 electric powered heater (50) because the substitution of one known heater for another would have yielded predictable results of being able to heat the barbeque grill apparatus and the food that is desired to be cooked. PNG media_image11.png 353 402 media_image11.png Greyscale Modified Figure 8 (Cai) PNG media_image12.png 246 450 media_image12.png Greyscale Modified Figure 9 (Cai) Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Konishi in view of Scherer’s Figures 1 and 11 as applied to claims 1-3, 6, 7, 9, 10, 12, 13, 15-17, and 20 above, and further in view of Cai (C.N. Patent Document No. 207821698). Konishi in view of Scherer’s Figures 1 and 11 teaches: Regarding claim 5, (See Modified Figure 7 and Scherer’s Figure 1 and 11 above) wherein reflecting material is applied on inner side of the first folding plate (Modified Figure 7) and the second folding plate (Modified Figure 7). “The interior side wall side 35 of the back section 32 possesses or is otherwise provided with a reflective heat-resistant surface finish or coating” (Pg. 6, Col. 6, Lines 20-22, Scherer). Konishi in view of Scherer’s Figures 1 and 11 does not teach: Regarding claim 5, wherein far-infrared reflecting material is applied on inner side of the first folding plate and the second folding plate. Cai teaches: Regarding claim 5, (See Modified Figures 8 and 9 above) wherein far-infrared reflecting material is applied on inner side of the plates (1, 2, and 3) “The heat reflector is made of silver aluminum alloy. The heat reflector reflects the received heat away. The heat is refracted to the grill by far-infrared rays 1 to 3 times” (Pg. 2, Paragraph 11, lines 1-2). Regarding claim 5, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Konishi in view of Scherer’s Figures 1 and 11 to incorporate the teachings of Cai to have far-infrared reflecting material applied on the inner sides of the first and second folding plates. Doing so allows for any far-infrared heat being emitted to reflect to the food being cooked without a large amount of far-infrared getting lost. PNG media_image13.png 403 539 media_image13.png Greyscale Modified Figure 10 (Gim) PNG media_image14.png 377 701 media_image14.png Greyscale Modified Figure 11 (Gim) PNG media_image15.png 539 545 media_image15.png Greyscale Modified Figure 12 (Gim) PNG media_image16.png 280 294 media_image16.png Greyscale Modified Figure 13 (Gim) Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Konishi in view of Scherer’s Figures 1 and 11 as applied to claims 1-3, 6, 7, 9, 10, 12, 13, 15-17, and 20 above, and further in view of Gim (K.R. Patent Document No. 101832620). Konishi in view of Scherer’s Figures 1 and 11 teaches: Regarding claim 11, (See Modified Figure 5 above) wherein the base part (16 and 17) of the bottom plate (Modified Figure 5) is a net-like frame. Konishi in view of Scherer’s Figures 1 and 11 does not teach: Regarding claim 11, wherein the base part of the bottom plate is a water tray for holding water. Gim teaches: Regarding claim 11, (See Modified Figures 10, 11, 12, and 13 above) wherein the base part (60) of the bottom plate (Modified Figure 10) is a water tray for holding water. Examiner note: the base part (60) has containing plates (Modified Figure 10) around the perimeter of the base part (60) and the base part (60) is depicted as being a uniform sheet that is not foraminous, thus the base part (60) is capable of holding water and being a water tray. Regarding claim 11, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Konishi in view of Scherer’s Figures 1 and 11 to incorporate the teachings of Gim to have a base part that is water tray capable of holding water. Doing so allows for any meats being grilled to stay moist and soft while being cooked. Having moisture in a grilled meat is considered more palatable than dry and tough meat. PNG media_image17.png 680 547 media_image17.png Greyscale Modified Figure 14 (Ming-Tang) Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over Konishi in view of Scherer’s Figures 1 and 11 as applied to claims 1-3, 6, 7, 9, 10, 12, 13, 15-17, and 20 above, and further in view of Chen, Ming-Tang (U.S. Patent Document No. 5007403), hereinafter Ming-Tang. Konishi in view of Scherer’s Figures 1 and 11 teaches: Regarding claim 14, (See Konishi’s Modified Figures 1, 2, and 4) there are two wind shielding plates (6a, 7a, 8a and 6b, 7a, 8a). Konishi in view of Scherer’s Figures 1 and 11 does not teach: Regarding claim 14, wherein there are two cavities respectively on top side of the two wind shielding plates for disposing a grill lever. Ming-Tang teaches: Regarding claim 14, (See Modified Figure 14 above) wherein there are two cavities (Modified Figure 14) respectively on top side of the two wind shielding plates (11 and 12) for disposing a grill lever (Modified Figure 14). Regarding claim 14, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Konishi in view of Scherer’s Figures 1 and 11 to incorporate the teachings of Ming-Tang to have two cavities respectively on top side of the two wind shielding plates for disposing a grill lever. Doing so allows the user of the apparatus to make a wider variety of foods popular in grilling, such as kabobs or a rotisserie chicken. PNG media_image18.png 427 430 media_image18.png Greyscale Modified Figure 15 (Xu) PNG media_image19.png 302 469 media_image19.png Greyscale Modified Figure 16 (Xu) Claims 18 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Konishi in view of Scherer’s Figures 1 and 11 as applied to claims 1-3, 6, 7, 9, 10, 12, 13, 15-17, and 20 above, and further in view of Xu et al. (C.N. Patent Document No. 113116175), hereinafter Xu. Konishi in view of Scherer’s Figures 1 and 11 teaches: Regarding claim 18, the first folding plate (Modified Figure 1). Regarding claim 19, the first heater (Modified Figure 7). Konishi in view of Scherer’s Figures 1 and 11 does not teach: Regarding claim 18, wherein a temperature sensor is disposed on the first folding plate to detect a grill temperature. Regarding claim 19, wherein when a detected temperature of the temperature sensor is larger than a first threshold, the first heater is stopped to be heated. Xu teaches: Regarding claim 18, (See Modified Figures 15 and 16 above) wherein a temperature sensor (128) is disposed on the first folding plate (120) to detect a grill temperature. Regarding claim 19, (See Modified Figures 15 and 16 above) wherein when a detected temperature of the temperature sensor (128) is larger than a first threshold, the first heater (132) is stopped to be heated. “In one possible technical solution, when the second temperature detection value reaches the second preset temperature value, the coil assembly stops heating to avoid potential hazards caused by excessive temperature and improve the safety of the heating device” (Pg. 9, Paragraph 51, lines 1-3). Regarding claim 18, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Konishi in view of Scherer’s Figures 1 and 11 to incorporate the teachings of Xu to have a temperature sensor disposed on the first folding plate. Doing so ensures the system operates within a desired range; this prevents potential damage to the grilling apparatus when it’s being used. Regarding claim 19, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Konishi in view of Scherer’s Figures 1 and 11 to incorporate the teachings of Xu to have the first heater stopped being heated when a detected temperature is larger than a first threshold. Doing so prevents further increases in the temperature reducing the risk that the food being cooked becomes burnt or over-cooked. Additionally, this feature helps to reduce the risk of a fire starting.

Patent Document No. 112806868) in view of Scherer’s Figures 1 and 11 (U.S. Patent Document No. 3358585). Zhang teaches: Regarding claim 1, (See Modified Figures 17 and 18 above) A barbecue grill apparatus (Modified Figure 17), comprising: a first folding plate (Modified Figure 17) with a first top part (Modified Figure 17), a first middle part (Modified Figure 17) and a first bottom part (Modified Figure 17); a second folding plate (Modified Figure 17) with a second top part (Modified Figure 17), a second middle part (Modified Figure 17) and a second bottom part (Modified Figure 17); a rotating connector (Modified Figure 17) for connecting the first bottom part (Modified Figure 17) and the second bottom part (Modified Figure 17) for the first folding plate (Modified Figure 17) and the second folding plate (Modified Figure 17) to rotate along the rotating connector (Modified Figure 17) to spread with a first angle (Modified Figure 18) to be an open mode (Modified Figure 18) and to rotate along the rotating connector (Modified Figure 17) to collapse with a second angle to a close mode “When the first box and the second box need to be locked, the push block is pushed towards the second box to drive the slider and the rotating rod to rotate in the same direction. The auxiliary spring deforms, rotating the first box and the second box so that they abut against each other” (Pg. 4, Paragraph 3, lines 1-4), wherein in the open mode (Modified Figure 18), a grill bracket (5) is placed between the first folding plate (Modified Figure 17) and the second folding plate (Modified Figure 17); Regarding claim 6, (See Modified Figures 17 and 18 above) further comprising a first bottom support (Modified Figure 18) and a second bottom support (Modified Figure 18) respectively disposed on outer side of the first bottom part (Modified Figure 17) of the first folding plate (Modified Figure 17) and the second bottom part (Modified Figure 17) of the second folding plate (Modified Figure 17), wherein the first bottom support (Modified Figure 18) and the second bottom support (Modified Figure 18) are extended to stand on a bottom surface (Modified Figure 18) to keep a folding space defined by the first folding plate (Modified Figure 17) and the second folding plate (Modified Figure 17) in the open mode (Modified Figure 18) with an opening facing upwardly (Modified Figure 18). Regarding claim 7, (See Modified Figures 17 and 18 above) wherein the first bottom support (Modified Figure 18) and the second bottom support (Modified Figure 18) are rotated with respect to the first folding plate (Modified Figure 17) and the second folding plate (Modified Figure 17) to spread for standing on the bottom surface (Modified Figure 18). Zhang does not teach: Regarding claim 1, a first heater placed in the first middle part to emit heat toward the grill bracket. Scherer’s Figures 1 and 11 teaches: Regarding claim 1, (See Modified Figure 7 and Scherer’s Figures 1 and 11 above) a first heater (25) placed in the first middle part (Modified Figure 7) to emit heat toward the grill bracket (30 in Figure 11). Regarding claim 1, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Zhang to incorporate the teachings of Scherer’s Figures 1 and 11 to have a first heater placed in the first middle part to emit heat toward the grill bracket. Doing so limits the user’s ability to come into contact with the first heater, which prevents severe burns from occurring. The location of the first heater is perpendicular and in the first folding plate, which is away from the main points of user interface, such as the grill bracket and grill lever, where the food is placed. PNG media_image22.png 355 510 media_image22.png Greyscale Modified Figure 19 (Shi) Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Zhang (C.N. Patent Document No. 112806868) in view of Scherer’s Figures 1 and 11 as applied to claims 1, 6, and 7 above, and further in view of Shi (T.W. Patent Document No. M350327). Zhang in view of Scherer’s Figures 1 and 11 teaches: Regarding claim 8, (See Zhang’s Modified Figures 17 and 18 above) wherein the first bottom support (Modified Figure 18) is rotatable and is located at the first bottom part (Modified Figure 17) of the first folding plate (Modified Figure 17) in the close mode, wherein the second bottom support (Modified Figure 18) is routable and is located at the second bottom part (Modified Figure 17) of the second folding plate (Modified Figure 17) in the close mode. Zhang in view of Scherer’s Figures 1 and 11 does not teach: Regarding claim 8, wherein the first bottom support is rotatable to be collected in a first exterior container of the first bottom part of the first folding plate in the close mode, wherein the second bottom support is routable to be collected in a second exterior container of the second bottom part of the second folding plate in the close mode. Shi teaches: Regarding claim 8, (See Modified Figure 19) wherein the first bottom support (12) is rotatable to be collected in a first exterior container (Modified Figure 19) of the first bottom part of the first folding plate in the close mode, wherein the second bottom support (12) is routable to be collected in a second exterior container (Modified Figure 19) of the second bottom part of the second folding plate in the close mode. Examiner note: In Zhang (See Modified Figures 17 and 18 above) the first bottom support (Modified Figure 18) is located at the first bottom part (Modified Figure 17) of the first folding plate (Modified Figure 17) and the second bottom support (Modified Figure 18) is located at the second bottom part (Modified Figure 17) of the second folding plate (Modified Figure 17), thus the first exterior container (Shi’s Modified Figure 19) and second exterior container (Shi’s Modified Figure 19) would also be located at the first bottom part (Modified Figure 17) of the first folding plate (Modified Figure 17) and at the second bottom part (Modified Figure 17) of the second folding plate (Modified Figure 17) respectively. Regarding claim 8, it would have been prima facia obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Zhang to incorporate the teachings of Shi to have to have the first bottom support extend outwardly from the exterior surface of the first folding plate and have the second bottom support extend outwardly from the exterior surface of the second folding plate, and have one first exterior container of the first bottom part of the first folding plate to collect one first bottom support and have one second exterior container of the second bottom part of the second folding plate to collect one second bottom support. Doing so allows for a more compact structure that is easily collapsible, thus making transport of the barbecue apparatus less costly and more convenient.
