§102
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 . This is the First Office action on the Merits from the examiner in charge of this application. Claim Objections Claim 4 is objected to because of the following informalities: line 2, “wherein the first one of the insulating layer” should be “wherein the first one of the insulating layers”. Appropriate correction is required. 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.

The refrigerator of claim 1, wherein the plurality of transparent panels includes: a first panel 61 that forms a front surface of the door; a second panel 64 spaced apart from the first panel 61 in the first direction; and a third panel 69,65 spaced apart from the second panel 64 in the first direction such that the second panel 64 is between the first panel 61 and the third panel 69,65, and the third panel covering the liner opening of the door liner 561; (Claim 8). The refrigerator of claim 7, wherein the panel assembly further includes: a first spacer 63 disposed between the first panel 61 and the second panel 64; and a second spacer 66 disposed between the second panel 64 and the third panel 69, and wherein the first spacer 63 is disposed further away from a center of the panel assembly than the second spacer 66 (such as shown in Fig. 12); (Claim 9). The refrigerator of claim 7, wherein an end of the second panel 64 is closer to an end of the door than an end of the third panel 69, and the end of the third panel 69 is closer to a center of the panel assembly than the end of the second panel 64 (Fig. 27); (Claim 12).
