Patentability shall not be negated by the manner in which the invention was made. 07-103 AIA The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. 07-23-aia AIA The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 07-21-aia AIA Claim (s) 10 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Saito in view of Bambang et. al. (US 20200015746 A1) herein referred to as “Bambang” . Regarding claim 10, Saito discloses: The stretchable device according to claim 1. Saito further discloses: wherein the main body portion extends in a first direction and has a first end portion and a second end portion on both sides in the first direction ([Figure 1]; Saito discloses the main body portion containing a first and second end portion) , Saito does not explicitly disclose: the stretchable device further comprising: a connection terminal connected to the first end portion and connectable to the second end portion. However, Bambang discloses; the stretchable device further comprising: a connection terminal connected to the first end portion and connectable to the second end portion. ([Figure 6a]; Bambang discloses terminals 28 and 29 that are able to be connected) It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the stretchable device as disclosed by Saito with the terminal as disclosed by Bambang. The motivation being to secure the device and allow adjustability ([0037]). Regarding claim 16, Saito discloses: The stretchable device according to claim 14. Saito further discloses: wherein the main body portion extends in a first direction and has a first end portion and a second end portion on both sides thereof in the first direction ([Figure 1]; Saito discloses a main body portion with a first and second end in a first direction) , Saito does not explicitly disclose: the stretchable device further comprising: a connection terminal connected to the first end portion and connectable to the second end portion. However, Bambang discloses; the stretchable device further comprising: a connection terminal connected to the first end portion and connectable to the second end portion. ([Figure 6a]; Bambang discloses terminals 28 and 29 that are able to be connected) It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the stretchable device as disclosed by Saito with the terminal as disclosed by Bambang. The motivation being to secure the device and allow adjustability ([0037]) . 07-21-aia AIA Claim (s) 11 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Saito . Regarding claim 11, Saito discloses: The stretchable device according to claim 1. Saito further discloses: wherein the stretchable device includes: a plurality of the stretchable wirings; ([Figure 2]; Saito discloses flexible wiring 23, which is seen as stretchable wiring, [Figure 1]; Saito discloses the wiring in both the projection and the main body which is seen as a plurality) a plurality of the projecting piece portions ([Figure 14]; Saito discloses a plurality of projecting piece portions) ; and a plurality of the bioelectrodes ([Figure 14]; Saito discloses the projection piece portions having electrode units (10)) , the main body portion extends in a first direction and has a first end portion and a second end portion on both sides thereof in the first direction ([Figure 1]; Saito discloses a main body with a first end portion and a second end portion) , each of the plurality of the stretchable wirings extends along the first direction from one end portion of the first end portion and the second end portion ([Figure 1]; Saito discloses wiring extending down the length of the main body which is seen as extending from one first end portion to a second first end portion) , each of the plurality of the bioelectrodes is electrically connected to the plurality of the stretchable wirings ([0007]; Saito discloses the electrode 10 being connected to the wires). Saito does not explicitly discloses: and in the plurality of the stretchable wirings, as a distance in the first direction from the one end portion to a portion connected to the bioelectrode increases, a width of the stretchable wiring increases. However, the relationship between distance and width of wire is well known as shown through the well-known equation R = ρ L A (Pouillets law) wherein R = total resistance ρ = intrinsic resistance L = distance of wire and A = cross sectional area. Any increase in length would proportionally increase the resistance and conversely any increase in width would decrease resistance. Therefore, it would be obvious to increase the width of wire to offset an increase in resistance caused by an increase in length of a wire. It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the stretchable device as disclosed by Saito with the increasing wire thickness. The motivation being applying the known technique of increasing wire thickness as the wire length increase to provide the predictable result of keeping the resistance stable. Regarding claim 17, Saito discloses: The stretchable device according to claim 14. Saito further discloses: wherein the stretchable device includes: a plurality of the stretchable wirings; ([Figure 2]; Saito discloses flexible wiring 23, which is seen as stretchable wiring, [Figure 1]; Saito discloses the wiring in both the projection and the main body which is seen as a plurality) a plurality of the projecting piece portions ([Figure 14]; Saito discloses a plurality of projecting piece portions) ; and a plurality of the bioelectrodes ([Figure 14]; Saito discloses the projection piece portions having electrode units (10)) , the main body portion extends in a first direction and has a first end portion and a second end portion on both sides thereof in the first direction ([Figure 1]; Saito discloses a main body with a first end portion and a second end portion) , each of the plurality of the stretchable wirings extends along the first direction from one end portion of the first end portion and the second end portion ([Figure 1]; Saito discloses wiring extending down the length of the main body which is seen as extending from one first end portion to a second first end portion) , each of the plurality of the bioelectrodes is electrically connected to the plurality of the stretchable wirings ([0007]; Saito discloses the electrode 10 being connected to the wires). Saito does not explicitly discloses: and in the plurality of the stretchable wirings, as a distance in the first direction from the one end portion to a portion connected to the bioelectrode increases, a width of the stretchable wiring increases. However, the relationship between distance and width of wire is well known as shown through the well-known equation R = ρ L A (Pouillets law) wherein R = total resistance ρ = intrinsic resistance L = distance of wire and A = cross sectional area. Any increase in length would proportionally increase the resistance and conversely any increase in width would decrease resistance. Therefore, it would be obvious to increase the width of wire to offset an increase in resistance caused by an increase in length of a wire. It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the stretchable device as disclosed by Saito with the increasing wire thickness. The motivation being applying the known technique of increasing wire thickness as the wire length increase to provide the predictable result of keeping the resistance stable.
