§103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 103 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. Claim(s) 1-5, and 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Akino (US 2012/0140972) in view of Wiederholt (US 2014/0153739). Regarding claim 1, Akino teaches A microphone capsule suspension assembly, comprising: a body (Akino figure 1, microphone case 1) comprising: an inner surface and an outer surface, wherein the inner surface defines an internal region that is configured to support a microphone capsule (Akino figure 1, microphone case 1, “The outer circumferential end of a bottom of the yoke 32, which is one of the magnetic circuit components of the microphone unit 3, is fitted in the inner circumferential surface of the upper end of a supporting cylinder 37”); an upper extension extending from the outer surface in a radial direction that extends from a central axis of the body (Akino figure 1, microphone unit case 36 extends from cylinder 37); and a lower extension extending from the outer surface in the radial direction (Akino figure 1, outer cylinder 42 extends from cylinder 37), wherein the upper extension and lower extension are spaced apart in a direction that is parallel to the central axis (Akino figure 1, the outer cylinder and supporting cylinder are spaced apart on the vertical axis which is parallel to the central axis of the device), however does not explicitly teach the upper extension and lower extension each comprise a wall that has a first wall thickness and comprises an array of indentations that have a second wall thickness formed therein, and the first wall thickness is greater than the second wall thickness. Wiederholt teaches the upper extension and lower extension (Wiederholt figures 1-2, top and bottom sound decoupling unit 40) each comprise a wall that has a first wall thickness (Wiederholt figure 3, second ends 42c-47c of each arm) and comprises an array of indentations that have a second wall thickness formed therein (Wiederholt figure 3, ¶0025, the walls around holes of shape-changing portions 42b-47b), and the first wall thickness is greater than the second wall thickness (Wiederholt figure 3, ¶0025, the second ends 42c-47c are thicker than the walls around holes of shape-changing portions 42b-47b). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to use the known technique of Wiederholt to improve the known microphone capsule of Akino to achieve the predictable result of improving sound decoupling (Wiederholt ¶0015). Regarding claim 2, Akino in view of Wiederholt teaches wherein a plurality of upper protrusions extend from an outer surface of the upper extension and are aligned in a circular array coaxial to a center axis of the body (Wiederholt figure 2, and ¶0024, bars 21 protrude the opening of the upper decoupling unit 40). Regarding claim 3, Akino in view of Wiederholt teaches wherein a plurality of lower protrusions extend from an outer surface of the lower extension and are aligned in a circular array coaxial to the center axis of the body (Wiederholt figure 2, and ¶0024, bars 21 protrude the opening of the lower decoupling unit 40). Regarding claim 4, Akino in view of Wiederholt teaches wherein the plurality of upper protrusions are offset from the plurality of upper indentions and the plurality of lower protrusions are offset from the plurality of lower indentions (Wiederholt figures 2-3, and ¶0024, bars 21 are offset from inner hole 42b-46b). Regarding claim 5, Akino in view of Wiederholt teaches wherein the array of indentions are segmented and radially disposed along the inner surface of the upper extension and comprise a thickness less than a thickness of the upper extension (Wiederholt figure 3, holes 42a-47a are less thick than holes 42b-47b). Regarding claim 7, Akino in view of Wiederholt teaches the upper extension and lower extension each further comprising a plurality of spokes having the first wall thickness between the array of indentions and wherein a ratio of a surface area of the indentions in each of the upper and lower extensions to a surface area of the spokes is 2:1 or less (Wiederholt, hole 42a vs second end 42c). Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Akino (US 2012/0140972) in view of Wiederholt (US 2014/0153739) in further view of Eveleigh (US 2020/0337186). Regarding claim 6, Akino in view of Wiederholt does not explicitly teach wherein the body comprises a material with a Shore A hardness of between about 30 and about 40. Eveleigh teaches wherein the body comprises a material with a Shore A hardness of between about 30 and about 40 (Eveleigh ¶0081). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to use the known technique of Eveleigh to improve the known microphone capsule of Akino in view of Wiederholt to achieve the predictable result of adjusting the durability of the device. Claim(s) 8-9 and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Akino (US 2012/0140972) in view of Wiederholt (US 2014/0153739) in further view of Tardo (US 5033093).
