Office Action

§112
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 Objections Claim 1-3, 13-15 objected to because of the following informalities: Regarding claim 1, in lines 5-6 the phrase “with respect to the other disk” should be changed to “with respect to other disk of the pair of disks”. Regarding claim 2, the phrase “a disk thickness direction” should be changed to “a disk thickness direction”. Regarding claim 3, the phrase “a side of the counter surface” should be changed to “the side of the counter surface”. Regarding claim 13, the phrase “a circumference of each disk” should be changed to “a circumference of each of the pair of disks”. Regarding claim 14, the phrase “and the pulverizing part of the other disk are a lap type formed in a concavoconvex shape so that these pulverizing parts overlap with each other” should be changed to “and the pulverizing part of the other disk of the pair of disks are a lap type formed in a concavo-convex shape so that the pulverizing parts overlap with each other”. Regarding claim 15, in line 5 the phrase “with respect to the other disk” should be changed to “with respect to other disk of the pair of disks”. Appropriate correction is required. 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 1-15 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 1 recites the limitation "the side" in line 21. There is insufficient antecedent basis for this limitation in the claim. Claims 2-14 are rejected because they depend from claim 1. Claim 15 recites the limitation "the side" in line 18. There is insufficient antecedent basis for this limitation in the claim. Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: Regarding claims 1 and 15, the closet prior arts is Jackson (US4688732A), however in the opinion of the Examiner that the arts of record neither anticipates nor render obvious the limitation of “ in a case where a line passing a center, in a disk thickness direction, of a thinnest part of an outer peripheral part of the central disk part and being orthogonal to a disk rotation center line is a reference line, each of a plurality of virtual segment pieces obtained by dividing a ring-shaped part on an outside in a radial direction relative to the thinnest part of the disk in units of a predetermined length in a disk circumferential direction is sectioned into a first piece on the side of the counter surface and a second piece on the side opposite to the counter surface by the reference line, and a virtual rotation moment about the first piece using, as a center, an intersection between the reference line and a line connecting a center of gravity of the first piece and a center of gravity of the second piece is a first moment and a virtual rotation moment about the second piece using the intersection as a center is a second moment, a ratio of a differential value between a value of the first moment and a value of the second moment to the value of the second moment is set to be 15% or less” in combination with the other limitations of the claim. Claims 2-14 are depended from claim 1. Claims 1 and 15 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
