Office Action

§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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 26 April 2024 had been considered by the Examiner. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they include the following reference character(s) not mentioned in the description: 228 (which is used to denote two parts) as well as 206 (as seen in at least fig. 3). Corrected drawing sheets in compliance with 37 CFR 1.121(d), or amendment to the specification to add the reference character(s) in the description in compliance with 37 CFR 1.121(b) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. 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 (i.e., changing from AIA to pre-AIA ) 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, 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 1-18 are rejected under 35 U.S.C. 103 as being unpatentable over Allard et al. (US 2013/0026855; hereinafter ‘Allard’), in view of Rohrbach (US 7,311,526; hereinafter ‘Rohrbach’). Regarding claim 1, Allard discloses a domestic appliance (10, at least figs. 1 and 7-12) comprising: a frame comprising a front face (at at least 24; fig. 1) and a rear face (12; as seen in at least fig. 1); a door (22; at least fig. 1) moveably attached to the frame between an open position and a closed position (as disclosed in at least paragraph [0035]), the door (22); and an electrical connector assembly (at least 98, 140; as seen in at least figs. 7-12; as disclosed in at least paragraphs [0038-0043]) for supplying an electrical load (as disclosed in at least paragraph [0038]), the electrical connector assembly transitionable between an engaged position and a disengaged position (as seen in at least figs. 7-9; as disclosed in at least paragraphs [0038-0043]), the electrical connector assembly comprising: a first electrical connector (at least 110: as seen in at least figs. 7-9) disposed at the frame (as seen in the figs.7-9), the first electrical connector comprising a contact pad (at least 110) and teaches a first magnetic element (not shown, but as suggested in at least paragraph [0047]), the contact pad (110) disposed at the front face apart from the door, the first magnetic element coupled to the contact pad (as suggested by paragraph [0047]), the first magnetic element disposed at the rear face, the first magnetic element defining a magnetic field; and a second electrical connector (also 110disposed at the pin housing, the second electrical connector comprising a second magnetic element floating within the aperture, the second magnetic element in selective engagement with the contact pad (components not shown, but as disclosed with respect to the reed switch [as seen in at least figs. 7-9; as disclosed in at least paragraph [0043]), wherein the first magnetic element applies a pull force to the second magnetic element to maintain engagement between the second magnetic element and the contact pad in the engaged position as suggested by paragraph [0043]). Allard discloses the claimed invention as indicated above. Allard further teaches the possibility of a variety of engagement means (as taught in at least paragraph [0047]). Rohrbach teaches a connector including a pin housing, the pin housing comprising a channel defining an aperture therethrough and a second electrical connector disposed at the pin housing, wherein the second electrical connector comprising a second magnetic element floating within the aperture, the second magnetic element in selective engagement with the contact pad (as seen in at least fig. 3). It would have been obvious to one having ordinary skill in the art before the effective filing date to include Rohrbach’s pin housing, the pin housing comprising a channel defining an aperture therethrough and a second electrical connector disposed at the pin housing, wherein the second electrical connector comprising a second magnetic element floating within the aperture, the second magnetic element in selective engagement with Allard’s contact pad.
