DETAILED ACTION 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 . This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Information Disclosure Statement The information disclosure statement (IDS) submitted on 2/5/2026, 3/16/2026, and 5/27/2026 was in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Terminal Disclaimer The terminal disclaimer filed on 5/27/2026 disclaiming the terminal portion of any patent granted on this application which would extend beyond the expiration date of PN 12176159 has been reviewed and is accepted. The terminal disclaimer has been recorded. Double Patenting The nonstatutory double patenting rejection is being withdrawn based on the approved Terminal Disclaimer mailed on 5/27/2026. Claim Rejections - 35 USC § 102 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 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 23, 24, 27, 28, 30-32, 34, 35, and 42 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Takada (US 20180115304 A1). With regards to claim 23. Takada disclose(s): (New) A load control apparatus comprising: one or more buttons (figs 1-7b), each of the one or more buttons including: an elongated portion (20; fig 4), the elongated portion having a first end (top portion of 20 in fig 4) and a second end (bottom portion of 20 in fig 4); a carrier (see multiple elements of housing 10 being around of 20 in fig 2) having a first surface (top surface of any of housing elements 10 being around 20 in fig 2) and a transversely opposed second surface (bottom surface of any of housing elements 10 being around 20 in fig 2), the carrier including an aperture that permits displaceable passage of the elongated portion therethrough (see 20 being through elements in 10; fig 2); and a diffuser portion (21; fig 4; [0046]) disposed about a perimeter of the first end of the elongated portion (top portion of 20 in fig 4), the diffuser portion having a light entrance surface (see bottom surface of 2a; fig 7a) and a light exit surface (see top surface of 2a; fig 7a), the light exit surface including at least one exit surface feature configured to permit at least a portion of light incident on the light entrance surface to exit from the diffuser portion in a radially outward pattern with respect to a longitudinal axis of the elongated portion (see 2b being “light-transmitting portion”; [0046]; fig 4; see 2b having a partial circular shape in fig 4; the examiner takes the position that light exiting from a partial circular shape has a radially outward pattern).

PNG media_image1.png 454 421 media_image1.png Greyscale With regards to claim 35. Takada disclose(s): (New) The load control apparatus of claim 30, further comprising, for each button of the one or more buttons, at least one light source (6; fig 7b; [0028]) disposed on the printed circuit board (7; [0028]) proximate the electric switching apparatus (5), the at least one light source configured to illuminate the first surface of the carrier of the respective button [0028-0029; 0045]. With regards to claim 42. Takada disclose(s): (New) The load control apparatus of claim 23, further comprising: a button cap (21; fig 4) affixed to the first end of the elongated portion (top portion of 20 in fig 4), wherein the diffuser portion (2b) is affixed to the button cap (see top of 21 in fig 4) and is displaceable along the longitudinal axis of the elongated portion (see button in fig 4 being pushed along axis of 20). 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 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 of this title, 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) 29, and 36-38 is/are rejected under 35 U.S.C. 103 as being unpatentable over Takada (US 20180115304 A1) in view of Krita (US 20150179366 A1). With regards to claim 29. Takada disclose(s): (New) The load control apparatus of claim 28, Takada does not disclose(s): wherein the at least one electrically open contact comprises: a first electrical contact disposed on the printed circuit board; a second electrical contact disposed on the printed circuit board and spaced apart from the first electrical contact; and a displaceable conductive dome disposed over the first electrical contact and the second electrical contact, wherein displacement of the elongated portion causes an elastic deformation of the conductive dome such that the conductive dome electrically conductively couples the first electrical contact and the second electrical contact. Krita teaches: wherein the at least one electrically open contact (14, 13; fig 4; [0050]) comprises: a first electrical contact disposed on the printed circuit board (see 13; fig 14; [0050]); a second electrical contact (see 13; fig 14; [0050]) disposed on the printed circuit board (7) and spaced apart from the first electrical contact (see 13; fig 14; [0050]); and a displaceable conductive dome disposed over the first electrical contact and the second electrical contact [0050], wherein displacement of the elongated portion causes an elastic deformation of the conductive dome (14; fig 4; [0050]) such that the conductive dome electrically conductively couples the first electrical contact and the second electrical contact [0050]. Before the effective filing date of the claimed invention, it would have been obvious for one of ordinary skill in the art to have modified the device/method/system of Takada by implementing the at least one electrically open contact comprises: a first electrical contact disposed on the printed circuit board; a second electrical contact disposed on the printed circuit board and spaced apart from the first electrical contact; and a displaceable conductive dome disposed over the first electrical contact and the second electrical contact, wherein displacement of the elongated portion causes an elastic deformation of the conductive dome such that the conductive dome electrically conductively couples the first electrical contact and the second electrical contact as disclosed by Krita in order to control the operation of a circuit as taught/suggested by Krita ([0050]). With regards to claim 36. Takada disclose(s): (New) The load control apparatus of claim 35, Takada does not disclose(s): wherein the at least one light source comprises a plurality of light sources disposed on the printed circuit board proximate the electric switching apparatus. Krita teaches: wherein the at least one light source comprises a plurality of light sources disposed on the printed circuit board proximate the electric switching apparatus (11, 12; fig 4; [0059]). Before the effective filing date of the claimed invention, it would have been obvious for one of ordinary skill in the art to have modified the device/method/system of Takada by implementing the at least one light source comprises a plurality of light sources disposed on the printed circuit board proximate the electric switching apparatus as disclosed by Krita in order to independently illuminate multiple indicia within a button as taught/suggested by Krita ([0058-0059]). With regards to claim 37. Takada as modified disclose(s): (New) The electric load control apparatus of claim 36, Krita further discloses: wherein each light source of the plurality of light sources comprises a first light source (11; fig 4) and a second light source (12) disposed on the printed circuit board proximate the electric switching apparatus (13) and spaced 180° apart from one another (see 11 and 12 being perpendicular to 13). With regards to claim 38. Takada disclose(s): (New) The load control apparatus of claim 36, Krita further discloses: wherein each light source of the plurality of light sources comprises a plurality of light-emitting diode (LED) light sources [0049, 0059]. Allowable Subject Matter Claim(s) 25, 26, 33, and 39-41 is/are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and overcome the Double Patenting rejections. Response to Arguments Applicant's arguments filed 5/27/2026 have been fully considered but they are not persuasive. Applicant asserts that the prior art, Takada, fails to disclose “a carrier having a first surface and a transversely opposed second surface, the carrier including an aperture that permits displaceable passage of the elongated portion therethrough” as recited in claim 1. To support this position, Applicant relies on paragraphs [0025] of Takada which discloses details of “support member 4” which has an “opening 4a” where part of the button is inserted. The applicant asserts that “it is unclear what specific portion of the housing 10 allegedly defines an aperture let alone one that permits displaceable passage of the elongated portion therethrough. At best, Takada's support member 4 includes an opening 4a that allows the support member 4 to support the operation button 2. But Takada's support member 4 is not one of the "multiple elements of housing 10" nor is it the claimed carrier. This is further evidenced by the body 20 (i.e., the alleged elongated portion) being disposed in the support member's 4 opening 4a, not some hole defined by the housing 10.” The examiner respectfully disagrees, First, the plain language of the limitation “a carrier having a first surface and a transversely opposed second surface, the carrier including an aperture that permits displaceable passage of the elongated portion therethrough” does not involve details of how the carried element fits in the carrier nor how the “surface”(s) are located in relation to the elongated portion. At most, the limitation requires two surfaces being “transversely opposed” and an “aperture” that permits the passage of the elongated portion. As pointed in the office action, there are multiple elements within the “light-transmitting operation button” 2 with a “housing” 10 among other elements (figs 1-7b in Takada) that meet such requirement. More specifically, Although Takada refers to each element besides “operation button” using other names such “housing”, “operation dial”, “support member”, etc., A person having ordinary skill in the art would understand that the multiple individual elements form a “button” device with multiple components. Therefore, support member 4 is part of the button device having multiple components of Takada, where support member 4 has at least two transversely opposed surfaces as shown in the annotated figure below. PNG media_image2.png 197 334 media_image2.png Greyscale Additionally, the examiner pointed in the office action mailed on 1/28/2026 that “multiple elements of housing 10 being around of 20 in fig 2” as the carrier. This position was taken based on the broadest reasonable interpretation of the claimed “carrier”. The examiner highlights that other physical components within the housing 10 also meet the requirements of permitting displaceable passage of the elongated portion therethrough either while operation or assembly of the unit. Such other physical components are annotated below. PNG media_image3.png 415 384 media_image3.png Greyscale For at least reasons above, the examiner maintains the rejection of records.
