DECISION ON APPEAL Appeal 2013-006356 Reexamination Control No. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 2 This is an appeal under 35 U.S.C. §§ 134(b) and 306 from the final rejection of claims 1, 2, 9-14, 19-34, and 45-63. Claims 3-8 and 15-18 have been cancelled. The Examiner has confirmed the patentability of claims 35- 44. We have jurisdiction under §§ 134(b) and 306. We affirm. STATEMENT OF THE CASE Merged Reexamination Proceedings A request for ex parte reexamination of U.S. Patent No. 6,243,254 (the „254 patent) was filed on January 29, 2010 and assigned Reexamination Control No. 90/010,836. A subsequent request for ex parte reexamination of the „254 patent was filed on February 2, 2011 and assigned Reexamination Control No. 90/011,473. The reexamination proceedings have been merged. The „254 patent, entitled “Dielectric Ceramic Composition and Laminated Ceramic Capacitor Using the Same,” issued June 5, 2001, to Nobuyuki Wada, Masamitsu Shibata, Takashi Hiramatsu, and Yukio Hamaji, based on Application No. 09/369,988, filed August 6, 1999. The „254 patent is said to be assigned to Murata Manufacturing Company, Ltd., said to be the assignee and real party in interest. Appellant’s Invention Appellant‟s invention relates to a laminated ceramic capacitor which satisfies the B-grade and X7R grade characteristics, using Ni for the inner electrodes. The dielectric material contains about 0.2 to 5.0 parts by weight of Li2O–(Si,Ti)O2–MO (MO is Al2O3 and ZrO2) or SiO2–TiO2–XO oxides Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 3 (XO is BaO, CaO, SrO, MgO, ZnO and MnO) relative to 100 parts by weight of a principal component represented by (Ba1-xCaxO)mTiO2 + αRe2O3 +βMgO + γMnO (Re2O3 is Y2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3 or Yb2O3). (Abstract.) Related Litigation The „254 patent has been asserted in a patent infringement suit, Murata Manufacturing Co. v. Samsung Electro Mechanics Co., No. 8:09-cv- 01124-DOC-AN (C.D. Cal. Oct. 1, 2009), and involved in an investigation at the International Trade Commission, Investigation No. 337-TA-692, Certain Ceramic Capacitors and Products Containing Same. Both the litigation and investigation have been terminated. The Claims Independent claim 1 is exemplary, with disputed limitations in italics: 1. A dielectric ceramic comprising[:] (Ba1-xCaxO)mTiO2 + αRe2O3 +βMgO + γMnO in which Re is at least one member selected from the group consisting of Y, Gd, Tb, Dy, Ho, Er and Yb; α, β, γ, m and x are molar ratios; 0.001 ≤ α ≤ 0.10; 0.001 ≤ β ≤ 0.12; 0.001< γ ≤ 0.12; 1.000 < m ≤ 1.035; and 0.005 < x ≤ 0.22, and Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 4 about 0.2 to 5.0 parts by weight of either a first sub-component or a second sub-component or a third sub-component relative to 100 parts by weight of (Ba1-xCaxO)mTiO2, wherein the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides, the first sub-component is a Li2O–(Si,Ti)O2–MO oxide in which M is at least one of Al and Zr, the second sub-component is a SiO2–TiO2–XO oxide in which X is at least one selected from the group consisting of Ba, Ca, Sr, Mg, Zn and Mn, and the third sub-component is SiO2. The Rejections Claims 1 and 45 stand rejected under 35 U.S.C. § 103(a) as being obvious over JP „232 (Japanese Patent Publication No. H8-31232; Feb. 2, 1996) and Sakabe (Y. Sakabe et al., Dielectric Materials for Base-Metal Multilayer Ceramic Capacitors, PROC. ELECTRONICS DIVISION FALL MEETING 103-104 (1986)). Claims 2, 9, 10, 21, 22, 46, 47, 52, and 53 stand rejected under 35 U.S.C. § 103(a) as being obvious over JP „232, Sakabe, and Sano „473 (U.S. Patent No. 5,742,473; Apr. 21, 1998). Claims 11-14, 19, 20, 23, 24, 27, 30-34, 48-51, 54, 55, 58, and 61-63 stand rejected under 35 U.S.C. § 103(a) as being obvious over Sano „473, JP „232 and Sakabe.

Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 5 Appellant relied upon the following 1 in rebuttal to the Examiner‟s rejection: Declaration under 37 C.F.R. § 1.132 of Ian Burn, dated December 2, 2010 (“First Burn Declaration”).

Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 6 ANALYSIS After Final Amendment Appellant argues that “Appellant filed the After-Final Amendment on May 1, 2012 proposing to amend for the first time the paragraphs at 2:11-36 and 3:5-29 [of the „254 patent] to correct errors in these paragraphs” (App. Br. 5) and that the issues raised are relevant to claim construction (App. Br. 4-6, 11-12; see also Reply Br. 4). However, because this After Final Amendment, filed May 1, 2012, was not entered by the Examiner, such arguments are not a part of the record, and accordingly, will not be considered. Claim Construction We are unpersuaded by Appellant‟s arguments (App. Br. 7-10, 13-14; see also Reply Br. 4-9) that the Examiner improperly construed the claimed composition of “(Ba1-xCaxO)mTiO2 + αRe2O3 +βMgO + γMnO.” The Examiner interpreted the claimed composition (Ba1-xCaxO)mTiO2 + αRe2O3 +βMgO + γMnO as “starting materials (i.e., materials before sintering).” (Ans. 6, 21-25.) We agree with the Examiner. In the “Summary of the Invention” section, the Specification of the „254 patent explains that: In one aspect, the present invention provides a laminated ceramic capacitor provided with a plurality of dielectric ceramic layers, inner electrodes formed between the dielectric ceramic layers and external electrodes being in electrical continuity with the inner electrodes, the dielectric ceramic layer being represented by the following formula: (Ba1-xCaxO)mTiO2+αRe2O3+βMgO+γMnO Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 7 . . . . [with] (Ba1-xCaxO)mTiO2 as a starting material to be used for the dielectric ceramic layer . . . (Col. 2, ll. 11-29 (emphasis added).) The Specification of the „254 patent further explains that: It is preferable to use the ceramic having the composition to be described hereinafter in order to improve the plating resistance. The dielectric ceramic layer in the laminated ceramic capacitor is represented by the following formula: (Ba1-xCaxO)mTiO2+αRe2O3+β MgO+γMnO . . . . [with] (Ba1-xCaxO)mTiO2 as a starting material to be used for the dielectric ceramic layers . . . . (Col. 3, ll. 5-23 (emphasis added).) Accordingly, the Specification of the „254 patent expressly states that the subscript “m” refers to the “starting material.” Additionally, the Specification of the „254 patent states: The dielectric ceramic layers 2a and 2b are composed of a dielectric ceramic composition having as principal components barium calcium titanate ((Ba1-x CaxO)mTiO2, . . . . . . . . The composition described above allows a laminated ceramic capacitor with high reliability and excellent insulating strength to be obtained, wherein the ceramic capacitor can be fired without endowing it with semiconductive properties even by firing in a reducing atmosphere . . . . Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 8 (Col. 4, ll. 31-46 (emphases added).) The language “wherein the ceramic capacitor can be fired,” in addition to reference to the “[t]he composition described above [((Ba1-x CaxO)mTiO2],” indicates that such composition with a subscript “m” has not been fired and thus, refers to a “starting material.” First, Appellant argues that “[t]he use of the subscript m is important because the subscript m, in the specification of the „254 patent . . . is used to refer to a sintered material and not to refer to starting materials.” (App. Br. 7.) In particular, Appellants argue that “[t]he „254 specification consistently refers to sintered materials with the subscript m and to starting materials or pre-sintered materials with the subscript n, except for the translation error.” (Id.) Appellants further argue that from paragraph 6 of the Second Burn Declaration, “the subscript m must refer to a sintered material because BaCO3 or TiO2 does not combine with the (Ba1- xCaxO)nTiO2 to form (Ba1-xCaxO)mTiO2 until after sintering.” (App. Br. 7-8; see also Reply Br. 5.) Paragraph 6 of the Second Burn Declaration states that: (Ba1-xCaxO)mTiO2 + αRe2O3 +βMgO + γMnO recited in claims 1 and 45 of the „254 cannot be starting materials. Claims 1 and 45 use the subscript m in (Ba1-xCaxO)mTiO2 instead of the subscript n to refer to a sintered material. The specification of the „254 patent . . . consistently refers to sintered materials with the subscript m and to starting materials or pre-sintered materials with the subscript n, as seen, for example, by comparing claims 1 and 45 and Table 2 of the „254 patent with Table 1 of the „254 patent. BaCO3 or TiO2 is added in the „254 patent to the starting materials to adjust the ratio m of (Ba, Ca)/Ti in the BCT. Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 9 (Burn Decl. ¶ 6.) However, such statements are inaccurate, because as discussed previously, the “Summary of the Invention” section from the Specification of the „254 patent expressly refers to the subscript “m” as “starting materials.” Paragraph 6 of the Second Burn Declaration further states that “[t]he subscript m must refer to a sintered material because BaCO3 or TiO2 only combine with the (Ba1-xCaxO)nTiO2 to form (Ba1- xCaxO)mTiO2 during sintering.” (Burn Decl. ¶ 6.) However, this statement in the Second Burn Declaration relied upon by Appellant lacks persuasive factual support because the Second Burn Declaration does not cite to any persuasive corroborating evidence. See In re Beattie, 974 F.2d 1309, 1313 (Fed. Cir. 1992.) Second, Appellant also argues that “[a]s explained in paragraph 7 of the Second Burn Declaration, the recitation of simple oxides (αRe2O3 +β MgO + γMnO) in claims 1 and 45 is consistent with the industry's convention for claiming sintered material.” (App. Br. 8; see also Reply Br. 7.) Paragraph 7 of the Second Burn Declaration states that: The recitation of simple oxides (αRe2O3 +βMgO + γMnO) in claims 1 and 45 is consistent with the industry‟s convention for claiming sintered material. This is the industry‟s convention for describing dielectric ceramics because the dielectric ceramic cannot be reduced to a single precise chemical formula. A different formula would be used for starting materials because different precursors, i.e., precursors other than Re2O3, MgO, and MnO, can be used that would result in Re2O3, MgO, and MnO being present in the dielectric ceramic. For example, it is Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 10 possible to use MgCO3 and MnCO3 as precursors instead of MgO and MnO. (Burn Decl. ¶ 7.) Again, these statements in the Second Burn Declaration relied upon by Appellant lack persuasive factual support because the Second Burn Declaration does not cite to any persuasive corroborating evidence. See Beattie, 974 F.2d at 1313. Third, Appellant argues that by applying “the doctrine of claim consistency” the “„[d]ielectric ceramic‟ refers to a sintered material that is contained in a fully formed capacitor as seen, for example, in claims 11-14, 19, 20, 23-34, 41-44, 48-51, and 54-63 that are each directed to a „laminated ceramic capacitor‟” and “[a]s explained in paragraph 8 of the Second Burn Declaration, one of ordinary skill in the art would have understood that the term „dielectric ceramic‟ in the phrase „the plurality of dielectric layers containing the dielectric ceramic‟ refers to a sintered material.” (App. Br. 9.) However, claims 11-14, 19, 20, 23-34, 41-44, 48-51, and 54-63 recite a “laminated ceramic capacitor,” which narrows the scope of the “dielectric ceramic” recited in independent claims 1 and 45, which does not require the broader recitation of “dielectric ceramic” to be a sintered material. Furthermore, paragraph 8 of the Second Burn Declaration states that: One of ordinary skill in the art would understand that the phrases “ceramic green sheet” and “ceramic slurry” mean starting materials. One of ordinary skill in the art would not understand the use of the terms “ceramic green sheet” and “ceramic slurry” in the „254 specification to change the definition of “dielectric ceramic” so as to include non-sintered Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 11 materials. One of ordinary skill in the art would have understood that the “dielectric ceramic” in the phrase “the plurality of dielectric layers containing the dielectric ceramic” as recited in claims 11-14, 19, 20, 23-34, 41-44, 48-51, and 54- 63 refers to a sintered material. (Burn Decl. ¶ 8.) Again, these statements in the Second Burn Declaration relied upon by Appellant lack persuasive factual support because the Second Burn Declaration does not cite to any persuasive corroborating evidence. See Beattie, 974 F.2d at 1313. Fourth, Appellant argues that “the Examiner misleadingly alleged that „dielectric ceramic‟ (1) is not generally recognized, understood, or used by lay persons; (2) is not defined in any dictionary to mean „sintered material‟; and (3) is not explicitly defined in the claims.” (App. Br. 10.) In particular, Appellant argues that “[t]he broadest reasonable interpretation of „dielectric ceramic‟ consistent with the „254 patent as understood by one of ordinary skill in the art is that „dielectric ceramic‟ refers to a sintered material.” (Id.) However, Appellant has not provided any persuasive evidence with respect to how one of ordinary skill in the art would interpret “dielectric ceramic.” Arguments of counsel cannot take the place of factually supported objective evidence. See, e.g., In re Huang, 100 F.3d 135, 139-140 (Fed. Cir. 1996). Last, Appellant argues that “the use of the term particle in claim 2 of the „254 patent is consistent with how the term particle is used in the „254 patent.” (App. Br. 13.) In particular, Appellant argues that “Sample Nos. 17 and 18 in this portion of the „254 patent refer to the laminated ceramic capacitors shown in Table 2 . . . and Table 3 . . . .” (Id.) Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 12 However, the Specification of the „254 patent, immediately following Table 3, explains that: The cross section of the laminated ceramic capacitor obtained was polished and subjected to chemical etching. It was found from scanning electron microscopic observation of the grain size in the dielectric ceramics that the grain size was almost equal to the particle size of the barium calcium titanate starting material in the samples having the compositions within the range of the present invention. (Col. 9, ll. 34-40 (emphasis added).) Thus, according to the Specification of the „254 patent, the “grain size” refers to the dielectric ceramic after sintering and “particle size” refers to the barium calcium titanate starting material. Therefore, reading the claimed composition (Ba1-xCaxO)mTiO2 in the context of the entire patent, in particular the subscript “m,” we agree with the Examiner that the composition (Ba1-xCaxO)mTiO2 refers to a starting material. § 103 Rejections We are unpersuaded by Appellant‟s arguments (App. Br. 14-15, 16- 22; see also Reply Br. 10-14) that the combination of JP „232 and Sakabe would not have rendered obvious independent claim 1, which includes the limitation “the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides.” The Examiner acknowledged that JP „232 does not disclose the limitation “the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides” (Ans. 8) and thus, relied upon Table I of Sakabe, which Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 13 lists impurities ranging from 0.09 to 0.002 weight %, as detected by inductively coupled mass spectroscopy, for teaching a (Ba0.85Ca0.15O)1.01TiO2 ceramic with a Na2O impurity content of 0.002 weight % (Ans. 9, 33; Sakabe, p. 104). The Examiner further found that “[i]f these impurities [Li2O and K2O] were detected and less than 0.005% by weight, the requirement that the alkali metal oxides is 0.02% by weight would still be met.” (Ans. 33.) The Examiner concluded that “it would have been obvious to use the starting materials of Sakabe as sample 36 of JP „232” because “Sakabe suggests to use such starting materials along with other additives containing elements recited in the „254 patent (and sample 36 of the JP „232) including additives containing Mn and Mg.” (Ans. 8.) We agree with the Examiner. JP „232 2 relates to “a non-reducing dielectric porcelain composition used in porcelain capacitors, particularly laminated porcelain capacitors having internal electrodes which have base metals such as nickel and copper as the main ingredients.” (¶ [0001].) The compositional formula by mole ratio of such porcelain capacitors is 100(Ba1-xCax)1+kTiO3 + aRE2O3 + bMnO + cMgO + dLi2O + eSiO2, such that RE is Y, Gd, Dy, Ho, Er or Vb. (Claim 3.) For “Sample 36” of JP „232, x = 0.10, k = 0.015, RE = Y, a = 1.0, b = 0.1, c = 2.0, d = 2.0, and e = 1.5. (¶¶ [0051]-[0052].) Sakabe relates to Ni-electrode multilayer ceramic capacitors (MLCs). (P. 103.) Sakabe explains that “[c]alcium, Mg, and Mn ions 2 Reference is made to the English-language translation provided by Appellant, submitted December 22, 2009. Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 14 were effective in inhibiting the reduction of BaTiO3 ceramics.” (Abstract.) Sakabe further explains that powders from the highest electrical grade BaCO3, CaCO3, SrCO3, MgCO3, TiO2, Nb2O5, and MnO2 were prepared to form a (Ba0.85Ca0.15O)1.01TiO2 ceramic, with an impurity content of 0.002 weight % Na2O. (P. 104; Table I.) A person of ordinary skill in the art would have recognized that incorporating the powders of Sakabe, which include Mg and Mn ions, for producing a Ni-electrode MLC, with the method of forming a non-reducing dielectric porcelain composition of JP „232, would improve JP „232 by providing the advantage of inhibiting the reduction of BaTiO3 ceramics during firing. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). Similarly, combining JP „232 and Sakabe is no more than the simple substitution of the known powders of Sakabe for the known powders of JP „232, with no unexpected results. Id. Thus, we agree with the Examiner (Ans. 8) that modifying JP „232 to incorporate the powders of Sakabe would have been obvious. First, Appellant argues that “[o]ne of ordinary skill in the art would have expected a large amount of Li to enter the BCT grains of JP „232 during sintering because the amount of Li significantly affects the electrical properties of the ceramic composition” and thus, “sample 36 of JP „232 does not include the feature of „the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides.‟” (App. Br. 15; see also Reply Br. 10.) As evidence, Appellant points to the Oosawa Declaration, the Fujikawa Declaration, the Ojima Declaration, the Nakanshi Declaration, the Oda Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 15 Declaration, the Maeda Declaration, and the First Burn Declaration. (App. Br. 15.) However, Appellant‟s arguments are not commensurate in scope with claims 1 and 45. Claims 1 and 45 recite that “the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides,” which does not exclude the later addition of Li2O. In other words, claims 1 and 45 only require that the (Ba1-xCaxO)mTiO2 contains less than about 0.02% by weight of alkali metal oxides, rather than requiring the dielectric ceramic to contain less than about 0.02% by weight of alkali metal oxides. Moreover, claim 1 further recites “about 0.2 to 5.0 parts by weight of either a first sub- component . . . wherein . . . the first sub-component is a Li2O–(Si,Ti)O2–MO oxide.” Thus, claim 1 does not exclude the presence of Li2O, only that “the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides.” Second, Appellant argues that “Sakabe et al. does not disclose Na2O as the one and only alkali metal oxide” and accordingly, “Sakabe et al. fails to teach or suggest that other alkali metal oxides (i.e., Li2O and K2O) are not permitted or that the permissible upper limit of inclusion of alkali metal oxides is 0.02% by weight.” (App. Br. 16.) However, claim 1 recites “the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides” (emphasis added), which is broad enough to encompass zero % by weight alkali metal oxides. Third, Appellant argues that “JP „232 and Sakabe et al. cannot be combined as suggested by the Examiner” because “neither JP „232 nor Sakabe et al. teaches or suggests that it is desirable to use starting materials Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 16 with fewer impurities” (App. Br. 16-17.) Similarly, Appellant argues that “contrary to the Examiner‟s allegations, one of ordinary skill in the art would not look to Sakabe‟s discussion of Gd and Sm as providing a reason or motivation to modify JP „232.” (Reply Br. 11.) However, the Examiner‟s articulated reasoning for combining JP „232 and Sakabe is based on the addition of Mg and Mn to dielectric materials, rather than using starting materials with fewer impurities or adding Gd and Sm, as argued by Appellant. (Ans. 8.) Fourth, Appellant argues that “JP „232 and Sakabe et al. are directed to different objects with respect to the temperature characteristics of the ceramic materials” and that “[b]oth paragraph 12 of the Second Burn Declaration and paragraph 10 of the Sakabe Declaration explain how the different objects with respect to the temperature characteristics of the ceramic materials are incompatible.” (App. Br. 17; see also Reply Br. 13.) Paragraph 12 of the Second Burn Declaration and paragraph 10 of the Sakabe Declaration state that: JP „232 and Sakabe are directed to different objects with respect to the temperature characteristics of the ceramic materials. The temperature characteristic requirements of JP „232 and Sakabe are incompatible. The object of JP „232 is to achieve more stringent X7R temperature characteristics in which the dielectric constant of the ceramic dielectric has a temperature dependence of ±15% at -55°C to +125 °C, while the object of Sakabe is to achieve less stringent E characteristic of the JIS characteristics in which the dielectric constant of the ceramic dielectric has a temperature dependence of -55% to +20% at - 25°C to +85 °C or F characteristic of the JIS characteristics in which the dielectric constant of the ceramic dielectric has a temperature dependence of -80 to +30% at -25 to +85°C.

(Burn Decl. ¶ 12; Sakabe Decl. ¶ 10.) However, such statements do point out with particularity or explain why JP „232 and Sakabe are directed towards different objectives. Instead, the declarations merely cite language from the two references that are worded differently with a conclusory statement that such references are incompatible. Furthermore, the statements in the Second Burn Declaration and the Sakabe Declaration relied upon by Appellant lack persuasive factual support because the declarations does not cite to any persuasive corroborating evidence that “[o]ne of ordinary skill in the art would not have relied on any portion of Sakabe to modify JP „232 to avoid destroying the stringent X7R temperature characteristics.” See Beattie, 974 F.2d at 1313. Fifth, Appellant argues that “[p]aragraph [0020] of JP „232 teaches away from limiting the alkali metal oxides to less than 0.002% by weight.” (App. Br. 20.) In particular, Appellant argues that “because Li2O is an alkali metal oxide, JP „232 teaches away from limiting the alkali metal oxides to less than 0.002% by weight because JP „232 requires at least 0.19% by weight of the alkali metal oxide Li2O.” (App. Br. 21; see also Reply Br. 14.) However, as found by the Examiner, this argument is not commensurate in scope with claims 1 and 45. (Ans. 35-36.) As discussed previously, claims 1 and 45 recite that “the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides,” which does not exclude the Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 18 later addition of Li2O. Claim 1 further recites “about 0.2 to 5.0 parts by weight of either a first sub-component . . . wherein . . . the first sub- component is a Li2O–(Si,Ti)O2–MO oxide.” Thus, claim 1 does not exclude the presence of Li2O, only that “the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides.” Paragraph [0020] of JP „232 is expressly silent regarding the content of alkali metal oxides in the BaCaO3 and accordingly, does not “teach away” from the claim limitation “the (Ba1- xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides.” Last, Appellant argues that “Sakabe et al.‟s use of iron (Fe) teaches away from combining JP „232 and Sakabe et al.” (App. Br. 21.) In particular, Appellants argues that “JP 3-80151, which was filed with the Supplemental After-Final Amendment of May 15, 2012, teaches that the addition of Fe decreases the dielectric constant of a dielectric material.” (Id.) Because this After Final Amendment, filed May 15, 2012, was not entered by the Examiner, JP 3-80151 is not evidence of record. Thus, we agree with the Examiner that the combination of JP „232 and Sakabe would have rendered obvious independent claim 1, which includes the limitation “the (Ba1-xCaxO)mTiO2 contains about 0.02% by weight or less of alkali metal oxides.” Accordingly, we sustain the rejection of independent claim 1 under 35 U.S.C. § 103(a). Independent claim 45 recites limitations similar to those discussed with respect to independent claim 1, and Appellant has not presented any additional substantive arguments with respect to this claim. We sustain the rejection of claim 45 for the same reasons discussed with respect to claim 1. Appeal 2013-006356 Reexamination Control Nos. 90/010,836 and 90/011,473 (merged) U.S. Patent No. 6,243,254 19 Although Appellant nominally argues the rejection of dependent claims 2, 9-14, 19-34, and 46-63 separately (App. Br. 22), the arguments presented do not point out with particularity or explain why the limitations of the dependent claims are separately patentable. Instead, Appellant summarily alleges that “Sano „473 and Tokuda „596, applied alone or in combination, fail to cure the deficiencies of JP „232 and Sakabe et al.” (Id.) We are not persuaded by these arguments for the reasons discussed with respect to claims 1 and 45, from which claims 2, 9-14, 19-34, and 46-63 depend. Accordingly, we sustain these rejections. DECISION The Examiner‟s decision rejecting claims 1, 2, 9-14, 19-34, and 45-63 is affirmed. Requests for extensions of time in this ex parte reexamination proceeding are governed by 37 C.F.R. § 1.550(c). See 37 C.F.R. § 41.50(f).
