Regarding claim 33, Garde discloses operating an induction cooktop apparatus [Spec cited: “…hob device, namely an induction hob device …”]. PNG media_image1.png 552 808 media_image1.png Greyscale Claim Rejections - 35 USC § 103 The following is a quotation of AIA 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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. 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. Claim 28 is rejected under 35 U.S.C. 103 as being unpatentable over Garde (EP 3028540 A1). Regarding claim 28, Garde discloses a third heating frequency unit (heating frequency unit 36a, fig.2), a set of fourth heating units (heating elements 20a, 22a, fig.2), said switching arrangement (circuit arrangement 40a, fig.2) configured to electrically allocate the set of fourth heating units (heating elements 20a, 22a) to the third heating frequency unit (heating elements 12a, 14a, 28a, fig.2). However, Garde does not disclose a set of fifth heating units. It would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify a cooktop apparatus, by including a set of fifth heating units, as it well known in the art of manufacturing design of duplication in part, in order to electrically allocate the set of fifth heating units to at least one of the second heating frequency unit and the third heating frequency unit.
