Office Action

§102 §103
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 . Claim Rejections - 35 USC § 102 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. Claims 1-6 and 16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Nelson (US 5,505,046). As to claim 1, Nelson discloses a refrigerator comprising: a main body including at least one storage chamber (Fig. 2); doors (col. 4, lines 61-62) provided to open or close the at least one storage chamber (col. 4, lines 15-29); a thermoelectric module 90 configured to cool down the at least one storage chamber; and at least one processor configured to control the thermoelectric module 90 (col. 10, lines 31-40); wherein the thermoelectric module includes internal elements 94 classified into a plurality of groups 94a and 94b; wherein the internal elements 94 in each of the plurality of groups are connected to each other in series (Fig. 4b); and wherein the plurality of groups 94a-b are connected in parallel with each other to a power line 160/162 connected to the thermoelectric module 90 (Fig. 4b). As to claim 2, Nelson discloses a start point of an arrangement of the internal elements 94 in each of the plurality of groups 94a-b connected to a positive power line 160 and an end point of the arrangement in each group connected to a negative power line 162 (Fig. 4b). As to claim 3, Nelson discloses the groups 94a-b being commonly connected to the positive and negative lines 160-162 (Fig. 4b). As to claim 4, Nelson discloses the internal elements 94 in different groups 94a-b being electrically disconnected from each other except for an input node and an output node (Fig. 4b). As to claim 5, Nelson discloses the elements 94 in the first group 94a and the elements 94 in the second group 94b being distributed entirely throughout the thermoelectric module 90 (Figs. 3 and 4b). As to claim 6, Nelson discloses arranged the thermoelectric module 90 on an upper end of the main body such that a heating portion faces an outside of the refrigerator and a cooling portion faces an inside of the refrigerator (Fig. 8; col. 12, lines 25-30). As to claim 16, Nelson discloses at least one processor configured to selectively operate a thermoelectric device including the thermoelectric module 90 based on an operating environment of the refrigerator (col. 10, lines 31-40). Claim Rejections - 35 USC § 103 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 7-8 and 12-15 are rejected under 35 U.S.C. 103 as being unpatentable over Nelson as applied in the rejections above, and further in view of Nakajima (US 2015/0121899). As to claims 7-8, Nelson does not explicitly teach a voltage sensing circuit, current sensing circuit, or the processor being configured to identify a loss of function as claimed. However, Nakajima teaches that it is known to utilize voltage and current sensing circuits to identify a loss of function of a thermoelectric module based on a variation in an operating current (paragraph 31). In light of this teaching it would have been obvious to a person having ordinary skill in the art, before the effective filing date, to modify Nelson to utilize voltage and current sensing to identify a loss of function in at least one of the groups 94a-b as claimed and taught by Nakajima in order to alert a user to system malfunction. As to claims 12-15, Nelson, as modified does not explicitly teach providing notifications as claimed. However, Official Notice is taken that provision of a service notification to a user via display, speaker, terminal device, server, etc. is a common and typical feature in the refrigeration art that would have been obvious to use in conjunction with the modified system of Nelson for the purpose of alerting a user of a potential malfunction of the thermoelectric module 90. Allowable Subject Matter Claims 9-11 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 any intervening claims. Claims 17-20 are allowed because the prior art of record does not teach or suggest the claimed method of controlling a thermoelectric refrigerator that includes determining whether power consumption of a group of thermoelectric devices exceeds a maximum for the group when identifying a loss of function of the group.
