Office Action

§102 §112
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 Status Claims 2-21 are pending. Claim 1 was canceled. Claims 2-21 are new. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 2-21 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 2 recites the limitation "the other portion" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 11 recites the limitation "the other portion" in line 3. There is insufficient antecedent basis for this limitation in the claim. Claim 18 recites the limitation "the other portion" in line 4. There is insufficient antecedent basis for this limitation in the claim. By virtue of dependency, claims 3-10, 12-17, and 19-21 are also rejected. 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.

Regarding Claim 8: Son teaches wherein the support (124) further comprises a circumferential wall (121 of 120) provided on an edge of the plate (124, see Figure 3), and wherein the circumferential wall (121 of 120) contacts at least a portion of a side surface of the extension part (126). Regarding Claim 9: Son teaches wherein the circumferential wall (wall 112 of 110) protrudes from the first surface of the plate (124, see Figure 3). Regarding Claim 10: Son teaches wherein the support (124) comprises a plate (124 is a plate, paragraph [0055]) contacting the first tray (110), and wherein the opening (holes for 123) is defined in the plate (see Figure 3).
