Office Action

§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 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 1-11 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 1, line 7, insert –of—after “consists”. Claim 1, lines 7-8, the limitation, “a first internal electrode disposed directly on a second internal electrode” is confusing. Are the first internal electrode and the second internal electrode the same (material) as the first and second internal electrodes already claimed in claim 1, line 2? Allowable Subject Matter Claims 12-17, 19-20 are allowed. Claim 1 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. Claims 2-11 would be allowable if rewritten 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 and to include all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: In combination with the other claim limitations, the prior art does not teach or suggest a multilayered capacitor: wherein the bottommost pair of internal electrodes consists of one of the first internal electrodes disposed directly on one of the second internal electrodes , wherein the aluminum nitride-based compound includes AIN, or a doped AIN compound in which AIN is doped with Ni, Co, Mn, Cr, V, Zn, Re, Ta, Nb, Ti, Zr, Mg, Sc, Er, Y, La, or a combination thereof, the dielectric layer includes dielectric grains, and a crystal orientation of the dielectric grains is c-axis crystal orientation (claim 1); and an internal electrode stack between the base layer and the dielectric layer; and an external electrode disposed on the base layer and disposed outside the capacitor body, wherein the dielectric layers include an aluminum nitride (AIN)-based compound including AIN, or a doped AIN compound in which the AIN is doped with Ni, Co, Mn, Cr, V, Zn, Re, Ta, Nb, Ti, Zr, Mg, Sc, Er, Y, La, or a combination thereof, the dielectric layers include a plurality of dielectric grains, and a crystal orientation of the dielectric grain is c-axis crystal orientation, the internal electrodes include a first internal electrode and a second internal electrode, the first internal electrode and second internal electrode include a conductive metal including Mo, W, Ru, Ti, Pt, Al, or a combination thereof, and conductive metals included in the first internal electrode and the second internal electrode are different, wherein the internal electrode stack consists of at least one layer of each of the conductive metals included in the first and second internal electrodes disposed on each other (claim 12). Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
