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. The factual inquiries 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. Claims 3-5 are rejected under 35 U.S.C. 103 as being unpatentable over Shoukyuu et al. (WO 2005/040698 A1, machine translation), hereafter referred to as “Shoukyuu,” in view of Ryu et al. (US 2010/0050681 A1), hereafter referred to as “Ryu.” Regarding Claim 3: Shoukyuu fails to teach wherein the guide groove comprises: a first guide groove; and a second guide groove extending in a different direction from the first guide groove. Ryu teaches a guide groove (447) comprises: a first guide groove (first 447); and a second guide groove (second 447) extending in a different direction from the first guide groove (see Figure 4). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided wherein the guide groove comprises: a first guide groove; and a second guide groove extending in a different direction from the first guide groove to the structure of Shoukyuu as taught by Ryu in order to advantageously provide secured fixing of wiring for the supply of power to the heater (see Ryu, paragraph [0032]). Regarding Claim 4: Shoukyuu fails to teach wherein the first guide groove is configured to guide a power terminal of the heater. Ryu teaches a first guide groove (first 447) is configured to guide a power terminal (423) of electric device (paragraph [0104]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided wherein the first guide groove is configured to guide a power terminal of the heater to the structure of Shoukyuu as taught by Ryu in order to advantageously provide secured fixing of wiring for the supply of power to the heater (see Ryu, paragraph [0032]). Regarding Claim 5: Shoukyuu fails to teach further comprising at least one connector connected to the power terminal of the heater and accommodated in the second guide groove. Ryu teaches at least one connector (37c) connected to a power terminal (423) of an electric device (paragraph [0104]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided at least one connector connected to the power terminal of the heater to the structure of Shoukyuu as taught by Ryu in order to advantageously provide secured fixing of wiring for the supply of power to the heater (see Ryu, paragraph [0032]). Shoukyuu modified supra fails to teach the one connector accommodated in the second guide groove. However, since the general condition of the claim is disclosed by the prior art references, it is not inventive to rearrange the parts of the structure. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided one connector connected to the power terminal of the heater and accommodated in the second guide groove the structure of Shoukyuu in order to advantageously provide secured fixing of wiring for the supply of power to the heater (see Ryu, paragraph [0032]). Furthermore, absent evidence of criticality, rearrangement of parts is merely design choice and would be obvious to a person of ordinary skill in the art would before the effective filing date of the claimed invention. See MPEP 2144.04 VI. A. and C. Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Shoukyuu et al. (WO 2005040698 A1, machine translation), hereafter referred to as “Shoukyuu,” in view of Son et al. (US 2013/0014535 A1), hereafter referred to as “Son.” Regarding Claim 13: Shoukyuu teaches wherein the tray (11) comprises: a second tray (11 is a second tray/bottom tray) configured to define another portion of an ice making chamber (cavities 12), wherein the support (34) is configured to support the second tray (11), and wherein the heater (16) is configured to provide heat to the second tray (11). Shoukyuu fails to teach wherein the tray comprises: a first tray configured to define a portion of the ice making chamber; and the first tray and the second tray together defining the ice making chamber. Son teaches a tray (110 and 120) comprises: a first tray (110) configured to define a portion (115) of an ice making chamber (115 and 122); and the first tray (110) and a second tray (120) together defining the ice making chamber (115 and 122). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have provided wherein the tray comprises: a first tray configured to define a portion of the ice making chamber; and the first tray and the second tray together defining the ice making chamber to the structure of Shoukyuu as taught by Son in order to advantageously provide spherical shaped ice (see Son, paragraphs [0048] and [0052]). Allowable Subject Matter Claims 6-9 are rejected to as being dependent upon a rejected base claim, but would be allowable if rewritten without any patentably significant broadening in independent form including all of the limitations of the base claim and any intervening claims.
