Office Action

§102
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 . Election/Restrictions Applicant’s election without traverse of claims 1-19 in the reply filed on 05/04/2026 is acknowledged. 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 (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 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. Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Crew Nenkusho (JP2011507326 A)(hereinafter Nenkusho). Regarding claim 1, Nenukusho anticipates a magnetic heating apparatus comprising: a first rotor (21) supporting a plurality of first permanent magnets (212, 213) in an alternating directions about a periphery thereof such that each pair of magnets, located directly on either side of any one of the first permanent magnets, have the same polarity which is opposite to a polarity of the magnet located therebetween (Fig. 2 -notice depiction below); PNG media_image1.png 295 256 media_image1.png Greyscale the plurality of first permanent magnets being spaced from a panel passageway (22); and a first rotor drive for rotating the first rotor, supporting the plurality of first permanent magnets to generate a changing magnetic field (Fig. 1, RC 25, G). Note: The limitations directed toward a panel passageway which facilitates passage of an assembled insulation panel, having a metallic core…for directly heating the metallic core of the assembled insulation panel as the assembled insulation panels passes therethrough are directed toward materials being worked upon by the magnetic heating apparatus. These limitations do not further reduce the structure of heating apparatus. Allowable Subject Matter Claims 2-19 are allowed.
