Office Action

§102 §103 §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 . Specification The disclosure is objected to because of the following informalities: Not every paragraph of the specification is numbered. Appropriate correction is required. Claim Objections Claims 8-10 are objected to because of the following informalities: Change “the reference direction” to “the predetermined reference direction” for clear antecedent basis. 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. Claim 13 is 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 13 recites the limitation "the second wiring unit and the third wiring unit". There is insufficient antecedent basis for this limitation in the claim. The parent claim does not disclose a second wiring unit and a third wiring unit, however claim 11 discloses disclose a second wiring unit and a third wiring unit.

Furthermore, Mashiko teaches a network circuit configured by connecting the plurality of arithmetic circuit units (Mashiko: Fig. 8 elements A1-A4; col 11 lines 41-51). 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 8-10 are rejected under 35 U.S.C. 103 as being unpatentable over Mashiko in view of Robinett (US 20120098566 A1), hereinafter “Robinett”. As per claim 8, Mashiko further teaches The arithmetic apparatus according to claim 4, Mashiko does not teach wherein the first reference plane and the second reference plane are arranged side by side to be orthogonal to a predetermined reference direction, and the wiring reference plane is set to be parallel to the reference direction. Robinett teaches wherein the first reference plane and the second reference plane are arranged side by side to be orthogonal to a predetermined reference direction, and the wiring reference plane is set to be parallel to the reference direction (Robinett: Fig. 5A-5B; [0048]; crossbars 507-X are on planes that are orthogonal to the plane of via 504). Therefore, it would have been obvious before the effective filing date of the claimed invention to one of ordinary skill in the art to modify, with a reasonable expectation of success, the resistive matrix of Mashiko with the teachings of Robinett. One would have been motivated to combine these references because both references disclose semiconductor arrays, “crossbar layers increase the bit density and decrease the planar area” (Robinett: [0026]). As per claim 9, Mashiko/Robinett further teaches The arithmetic apparatus according to claim 8, wherein the wiring reference plane is set to be parallel to the reference direction and the extending direction of the plurality of output lines of the first arithmetic circuit unit (Mashiko: Fig. 8 elements B11-B14). As per claim 10, Mashiko/Robinett further teaches The arithmetic apparatus according to claim 8, wherein the common wiring unit includes a plurality of reference wires that is arranged in parallel and extends in an identical direction on the wiring reference plane, and the extending direction of the plurality of reference wires is set to be parallel to be the reference direction (Robinett: Fig. 5A-5B element 504). It would have been obvious before the effective filing date of the claimed invention to one of ordinary skill in the art to modify, with a reasonable expectation of success, the resistive matrix of Mashiko with the teachings of Robinett for at least the same reasons as discussed above in claim 8.
