DESPEN and JAMES A. MENNELL _______________ Appeal 2019-006991 Application 14/922,829 Technology Center 1700 _______________ Before MICHAEL P. COLAIANNI, GEORGE C. BEST, and DEBRA L. DENNETT, Administrative Patent Judges. DENNETT, Administrative Patent Judge. DECISION ON APPEAL1 Pursuant to 35 U.S.C. § 134(a), Appellant2 appeals from the Examiner’s decision to reject claims 1–8, 13–15, 24, 25, 28–32, 34, and 36– 43 of Application 14/922,829, which constitute all the claims pending in this 1 In our Decision, we refer to the Specification filed Oct. 26, 2015 (“Spec.”) of Application 14/922,829 (“the ’829 Application”); the Non-Final Office Action dated Mar. 8, 2018 (“Non-Final Act.”); the Appeal Brief filed Feb. 6, 2019 (“Appeal Br.”); Corrected Appeal Briefs filed Mar. 19, 2019 and Apr. 23, 2019 (“Corrected Appeal Br.”); the Examiner’s Answer dated July 31, 2019 (“Ans.”); and the Reply Brief filed Sept. 27, 2019 (“Reply Br.”). 2 “Appellant” refers to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies Carbon Technology Holdings, LLC as the real party in interest. Appeal Br. 2. Appeal 2019-006991 Application 14/922,829 2 application. Because at least one of the claims on appeal has been rejected at least twice, we have jurisdiction under 35 U.S.C. § 6(b). For the reasons set forth below, we AFFIRM IN PART. BACKGROUND The ’829 Application relates to halogenated biogenic activated carbon compositions. Spec. ¶ 2. The ’829 Application describes activated carbon as useful for controlling mercury emissions. Id. ¶ 5. The ’829 Application teaches that known processes to produce activated carbon generally require large energy inputs and suffer from low yields. Id. ¶ 3. According to the Specification, the described activated carbon composition is more efficiently activated for controlling mercury and other emissions in an economical way. Id. ¶¶ 5, 39, 102. Claims 1, 28, and 41 are representative of the ’829 Application’s claims and are reproduced below from the Appeal Brief’s Claims Appendix. 1. A halogenated activated carbon composition, said composition comprising, on a dry basis, at least 85 wt% carbon; a halogenated compound; and a copper halide or Dead Sea salt, wherein the halogenated compound and/or the salt are present in a total amount of about 0.1 wt% to about 15 wt%. Appeal Br. 57 (Claims App.). 28. A biogenic activated carbon composition comprising, on a dry basis: 80 wt% or more total carbon; 10 wt% or less hydrogen; and a first salt comprising a halogenated compound selected from the group consisting of copper bromide, copper chloride, and combinations thereof; and a second salt, Appeal 2019-006991 Application 14/922,829 3 wherein said halogenated compound and said second salt are present in a total amount of about 0.2 wt% to about 20 wt%, and wherein the second salt is optionally halogenated. Appeal Br. 59 (Claims App.). 41. An activated carbon product comprising biogenic activated carbon and Dead Sea salt. Appeal Br. 60 (Claims App.).

Claims 13–15, 28–32, 34, and 36–43 under 35 U.S.C. § 112(b) as indefinite.5 Non-Final Act. 2. 2. Claims 1–7, 13–15, 24, 25, 28–32, 34, and 36–43 under 35 U.S.C. § 103 as unpatentable over McNamara, as evidenced by Maor and Toomey.6 Non-Final Act. 2. 3. Claims 1, 5, 7, 8, 28, and 29 under 35 U.S.C. § 102(a)(1) as anticipated by Sinha. Non-Final Act. 3. 4. Claims 1, 4, 5, 7, 8, 28, 29, and 36 under 35 U.S.C. § 103 as unpatentable over Sinha. Non-Final Act. 3. 3 Because this application claims priority to an application filed after the March 16, 2013 effective date of the America Invents Act, we refer to the AIA version of the statutes. 4 The Examiner’s rejection of claim 8 under 35 U.S.C. § 112(a) was withdrawn in the Answer. Ans. 3. 5 The Examiner rejected claim 8 under 35 U.S.C. § 112(b) as indefinite “for the [same] reasons” this claim was rejected under 35 U.S.C. § 112(a). Non- Final Act. 2. The Examiner does not explicitly state that the indefiniteness rejection of claim 8 is withdrawn in the Answer. Because the rejection of claim 8 under 35 U.S.C. § 112(a) was withdrawn and claim 8 is not included in the Answer’s statement of the § 112(b) rejection, we agree with Appellant that the rejection of claim 8 under 35 U.S.C. § 112(b) was also withdrawn. Ans. 3, 4; Reply Br. 4. 6 In response to Appellant’s arguments that Maor and Toomey cannot be combined with McNamara, the Examiner clarifies in the Answer that Maor and Toomey are relied upon for evidentiary purposes. Ans. 7 (explaining that Maor and Toomey “are not being combined” with McNamara, but are “cited to show facts.”). Appeal 2019-006991 Application 14/922,829 5 5. Claim 41 under 35 U.S.C. § 103 as 35 U.S.C. § 102(a)(1) as anticipated by Curnutt, as evidenced by Maor.7 Non-Final Act. 4. 6. Claims 1, 4–8, 13–15, 24, 25, 28–31, 34, and 36–43 under 35 U.S.C. § 103 as unpatentable over Curnutt, as evidenced by Maor, Toomey, and Stencel.8 Non-Final Act. 4. DISCUSSION Ground 1: Rejection of claims 13–15, 28–32, 34, and 36–43 as indefinite The Examiner concludes that claims 13–15 are indefinite because these claims depend upon a claim that has been canceled. Non-Final Act. 2. The evidence is sufficient to establish a prima facie case of indefiniteness. See Corrected Appeal Br. 7 (Claims App.) (filed Mar. 19, 2019), Corrected Appeal Br. 6 (Claims App.) (filed Apr. 23, 2019). We sustain the rejection of claims 13–15 as indefinite. The Examiner determines that claims 30–32 are indefinite because it is unclear how a halogenated compound, which is also a salt, can possess a concentration “less than 100% of itself.” Non-Final Act. 2. Appellant does 7 In Ground 5, the Examiner relies on Maor for evidentiary purposes only. Id. at 9, 10. See In re Spada, 911 F.2d 705, 708 (Fed. Cir. 1990) (“Rejection for anticipation or lack of novelty requires, as the first step in the inquiry, that all the elements of the claimed invention be described in a single reference.”). But cf. Telemac Cellular Corp. v. Topp Telecom, Inc., 247 F.3d 1316, 1328 (Fed. Cir. 2001) (“[R]ecourse to extrinsic evidence is proper to determine whether a feature, while not explicitly discussed, is necessarily present in a reference.”). 8 In Ground 6, the Examiner explains in the Answer that Maor, Toomey, and Stencel are relied upon as evidence only. Ans. 9, 10. Appeal 2019-006991 Application 14/922,829 6 not contest the Examiner’s position or clarify the meaning of the recitations found in claims 30–32. See generally Appeal Br. 12–14; Reply Br. 4. We sustain the rejection of claims 30–32 as indefinite. Discerning the proper scope of claims 13–15 and 30–32 would require undue and improper speculation. Without reaching the merits, we summarily reverse the rejections of claims 13–15 and 30–32 under 35 U.S.C. § 103 over McNamara, as evidenced by Maor and Toomey (Ground 2), and of claims 13–15, 30, and 31 over Curnutt, as evidenced by Maor, Toomey, and Stencel (Ground 6). See In re Steele, 305 F.2d 859, 862 (CCPA 1962) (“[W]e do not think a rejection under 35 U.S.C. § 103 should be based on such speculations and assumptions.”). The Examiner determines that claims 28 and 41 are indefinite. The Examiner concludes that is unclear how the claimed “activated carbon” is “biogenic” because any elemental carbon obtained from the earth, such as coal, originated from living “plants and/or dinosaurs.” Non-Final Act. 2. According to the Examiner, “no difference is imparted by the term [‘biogenic’].” Id. at 3. The Examiner improperly rejects a claim as failing to meet the statutory requirements of 35 U.S.C. § 112(b) when Appellant has provided a satisfactory response in “the form of . . . a separate definition of the unclear language, or, in an appropriate case, a persuasive explanation for the record of why the language at issue is not actually unclear.” In re Packard, 751 F.3d 1307, 1311 (Fed. Cir. 2014). We are persuaded by Appellant’s arguments that the Specification’s definition of “biogenic” reasonably apprises the skilled artisan of the scope of the invention. Appeal Br. 12. Appellant’s relied-upon passage Appeal 2019-006991 Application 14/922,829 7 adequately describes to one of skill in the art that the limitations directed to biogenic activated carbon do not encompass all elemental carbon that originates from the earth. See Spec. ¶ 49. Rather, claims 28 and 41 are limited to elemental carbon, which “is renewable on time scales of months, years, or decades.” Id.; see also id. ¶ 93. Contrary to the Examiner’s position, the claimed “biogenic activated carbon” does not encompass coal because coal is not renewable within these time scales. See Non-Final Act. 2; see also Spec. ¶ 49 (describing that “[n]on-biogenic materials may be . . . renewable on time scales of centuries, thousands of years, millions of years, or even longer geologic time scales.”). Appellant, therefore, shows that the Examiner reversibly errs in concluding that claims 28 and 41 are unclear as to the meaning of the term “biogenic.” We do not sustain the rejection of claims 28, 29, 34, and 36–43 as indefinite. See 37 C.F.R. § 41.37(c)(1)(iv). Ground 2: Rejection of claims 1–7, 13–15, 24, 25, 28–32, 34, and 36– 43 as obvious over McNamara, as evidenced by Maor and Toomey The Examiner rejects claims 1–7, 13–15, 24, 25, 28–32, 34, and 36– 43 over McNamara, with evidence from Maor and Toomey. See Non-Final Act. 3–4. Because we consider the evidence insufficient to establish a prima facie case of obviousness with regard to recitations found in each of independent claims 1, 28, and 41, we need only address claims 1, 28, and 41. Claims 1 and 28 With respect to claims 1 and 28, the Examiner finds, inter alia, McNamara teaches an activated carbon having less than 10% metal halide dopants. Id. at 3. The Examiner reasons that the remaining composition Appeal 2019-006991 Application 14/922,829 8 consists of at least 90% carbon. Id. at 3; see also id. at 4 (concluding that “[w]hen pure carbon is added to 10% of a salt, it is self-evident that the resultant composition is 90% carbon.”) (Emphasis added). Appellant argues that McNamara fails to teach or suggest each and every element of independent claims 1 and 28, including a composition comprising at least 85 and 80 weight percent carbon, respectively, on a dry basis. Appeal Br. 20, 28. Appellant contends that the disputed carbon concentrations are not inherently disclosed in McNamara’s coal based compositions. Id. at 20, 26, 28; Reply Br. 5. In addition, McNamara does not specify any weight percent of carbon present in any of the disclosed compositions, according to Appellant. Appeal Br. 21. Appellant argues that McNamara’s coal based compositions include ash impurities, which are not removed and “will necessarily . . . decrease the weight percent of carbon.” Id. at 22 (citing McNamara 4:32–41; 12:24–30; 12:61–63; Tables I–III, VIII). Appellant argues that “[i]mpurities, such as ash [and sulfur] . . . are necessarily present in carbon obtained from coal . . . , unless otherwise removed.” Appeal Br. 48 (citing Stencel 1:20–29, 2:56–60, 6:21–25, 7:34– 38). The Examiner does not demonstrate prima facie obviousness by a preponderance of the evidence. See In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992) (“[P]atentability is determined on the totality of the record, by a preponderance of evidence with due consideration to persuasiveness of argument”). The Examiner errs in at least one important factual finding— McNamara does not teach a composition comprising pure carbon with metal halide dopants (compare Non-Final Act. 4; Ans. 7–8 with McNamara 4:32– 41; Tables I–III, VIII (disclosing use of coal based activated carbon in which Appeal 2019-006991 Application 14/922,829 9 ash constituents are present)). Such a factual error demonstrates a lack of “rational underpinning” to support obviousness. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”). We find no support in McNamara for any teaching of the claimed carbon weight percentage amounts. Rather, our review of McNamara (along with Stencel) shows that the coal feedstock used in the known activated carbon composition is not a source of pure carbon. McNamara 12:26–30, 12:60–63, Table VIII; Stencel 6:20–26, 7:34–38. McNamara’s use of coal based activated carbon suggests nothing in terms of carbon purity. According to the Examiner, “there would be no reason to believe that other extraneous materials would be present.” Ans. 7–8. The Examiner contends that Appellant “has not established that there is so much” extraneous impurities in the coal based activated carbon “that it would reduce the carbon below the claimed levels.” Id. at 8. However, the Examiner’s arguments improperly shift the burden of factually supporting the obviousness rejection to Appellant. The Examiner bears the initial burden of presenting a prima facie case of unpatentability. Oetiker, 977 F.2d at 1445. A prima facie case is established when the party with the burden of proof points to evidence that is sufficient, if uncontroverted, to entitle it to prevail as a matter of law. See Saab Cars USA, Inc. v. United States, 434 F.3d 1359, 1369 (Fed. Cir. 2006). Here, the Examiner has not met the initial burden of presenting a prima facie case of obviousness of claims 1 and 28, and, therefore, has not Appeal 2019-006991 Application 14/922,829 10 properly shifted the burden of coming forward with rebuttal or argument onto Appellant. In re Rijckaert, 9 F.3d 1531, 1532 (Fed. Cir. 1993). Furthermore, claim 28 recites a “biogenic activated carbon.” Appeal Br. 59 (Claims App.). As discussed in Ground 1, the claimed “biogenic activated carbon” does not encompass McNamara’s coal based compositions. See Spec. ¶ 49. We do not sustain the rejection of claims 1 and 28 under § 103 over McNamara, as evidenced by Maor and Toomey. We also do not sustain the rejection of claims 2–7, 24, 25, 29, 34, and 36–40 which depend from claims 1 and 28. See 37 C.F.R. § 41.37(c)(1)(iv). Claim 41 Claim 41 recites “[a]n activated carbon product comprising . . . Dead Sea salt.” Appeal Br. 60 (Claims App.). The Examiner relies upon Maor as evidence that the potassium chloride disclosed in McNamara describes the claimed Dead Sea salt. Non- Final Act. 3 (citing Maor Table 1); see also Ans. 7. Appellant argues that Maor’s explicit teaching that Dead Sea salt is a “salt mixture comprising the ingredients as described in table 1 and table 2” establishes that Dead Sea salt comprises potassium chloride, but not that McNamara’s disclosure of potassium chloride is a disclosure of Dead Sea salt. Appeal Br. 25; see also Maor 3:47–48 (describing Table 1 in which potassium chloride is listed among 7 compounds and insoluble matter as “[m]ajor constituents of the Dead Sea salt.”). Appellant argues that McNamara fails to teach Dead Sea salt. Appeal Br. 25. During prosecution, an application’s claims are given their broadest reasonable scope consistent with the specification. In re Am. Acad. of Sci. Appeal 2019-006991 Application 14/922,829 11 Tech. Ctr., 367 F.3d 1359, 1364 (Fed. Cir. 2004). “[A] patentee may choose to be his own lexicographer and use terms in a manner other than their ordinary meaning, as long as the special definition of the term is clearly stated in the patent specification or file history.” Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996). The Specification provides that Dead Sea salt is “salt that is obtained from the Dead Sea in the Jordan Rift Valley” and that “[t]he exact composition of the Dead Sea water varies . . . , but predominantly includes magnesium chloride, potassium chloride, and high amounts of bromide salts.” Spec. ¶ 63. Applying this definition, we agree with Appellant that Maor provides insufficient evidence that McNamara’s potassium chloride teaches or suggests the claimed Dead Sea salt. Appeal Br. 25. Furthermore, claim 41 recites “[a]n activated carbon product comprising biogenic activated carbon.” Id. at 60 (Claims App.). As set forth supra in Ground 1, the claimed “biogenic activated carbon” does not encompass McNamara’s coal based compositions. See Spec. ¶ 49. We do not sustain the rejection of claim 41 under § 103 over McNamara, as evidenced by Maor and Toomey. We also do not sustain the rejection of claims 42 and 43 which depend from claim 41. See 37 C.F.R. § 41.37(c)(1)(iv). Ground 3: Rejection of claims 1, 5, 7, 8, 28, and 29 as anticipated by Sinha The Examiner rejects claims 1, 5, 7, 8, 28, and 29 as anticipated by Sinha. See Non-Final Act. 3. Appeal 2019-006991 Application 14/922,829 12 Because we consider the evidence insufficient to establish a prima facie case of anticipation with regard to recitations found in each of independent claims 1 and 28, we need only address claims 1 and 28. The Examiner finds “Sinha teaches, especially in col. 6–7, copper halide and PdCl[2], with 89.2% carbon (based upon the amounts reported).” Id. at 3. The Examiner reasons that because Sinha discloses numerous compositions “having 0.8% of a metal, 10% CuCl[2]” with “no other components recited, the carbon support must be the remainder.” Ans. 8 (citing Sinha Table 1) (emphasis added). Appellant argues that Sinha fails to teach each and every element of independent claims 1 and 28, including a composition comprising at least 85 and 80 weight percent carbon, respectively, on a dry basis. Appeal Br. 33, 37. Appellant contends that the disputed carbon concentrations are not inherently disclosed in Sinha’s coal. Id. at 33, 37. In addition, Sinha’s activated carbon is obtained from coal, which includes ash impurities, according to Appellant. Id. at 34. In the absence of any evidence that Sinha’s ash impurities are removed, Appellant contends that the presence of ash shows error in the Examiner’s assumption that the activated carbon’s coal based portion is purely carbon. Id. (citing McNamara 12:24–30; 12:61– 63; Table VIII). The Examiner fails to establish inherency, which requires more than an assumption that pure carbon can be calculated from a coal-based activated carbon having 0.8% metal and 10% CuCl2. Ans. 8. Inherency requires that the claimed carbon weight percent amount must necessarily be present in Sinha. In re Robertson, 169 F.3d 743, 745 (Fed. Cir. 1999). To establish inherency, “the examiner must provide a basis in fact and/or Appeal 2019-006991 Application 14/922,829 13 technical reasoning to reasonably support the determination that the allegedly inherent characteristic necessarily flows from the teachings of the applied prior art.” Ex parte Levy, 17 USPQ2d 1461, 1464 (BPAI 1990). Here, the Examiner’s argument that “the carbon support must be the remainder” because no other support components are disclosed is speculative and unsupported by evidence. Ans. 8 (emphasis added). The fact that Sinha describes “no other components” does not indicate that the activated carbon’s coal-based portion is purely carbon. Id. at 8; see also Appeal Br. 34. Furthermore, claim 28 recites a “biogenic activated carbon.” Appeal Br. 59 (Claims App.). As set forth supra in Ground 1, the claimed “biogenic activated carbon” does not encompass Sinha’s coal based compositions. See Spec. ¶ 49. We do not sustain the Examiner’s rejection of claims 1 and 28 as anticipated by Sinha. Claims 5, 7, 8, and 29 fall with claims 1 and 28. See 37 C.F.R. § 41.37(c)(1)(iv). Ground 4: Rejection of claims 1, 4, 5, 7, 8, 28, 29, and 36 as obvious over Sinha The Examiner rejects claims 1, 4, 5, 7, 8, 28, 29, and 36 as obvious over Sinha. See Non-Final Act. 3. Because we consider the evidence insufficient to establish a prima facie case of obviousness with regard to recitations found in each of independent claims 1 and 28, we need only address claims 1 and 28. Appellant contends that claims 1 and 28 are nonobvious because the Examiner “points to discrete elements of the present claims as allegedly being present in” Sinha, “but no motivation to combine those elements is Appeal 2019-006991 Application 14/922,829 14 provided, no evidence is provided that such modification would be routine, and no assertion of a reasonable expectation of success of arriving at the presently claimed invention [is] made.” Appeal Br. 39. The Examiner responds that “Sinha teaches . . . that the amount of metals can be adjusted as desired.” Ans. 9 (citing Sinha 3:12–17). According to the Examiner, “optimizing the amount of carbon” can be accomplished “by adjusting the amount of non-carbon dopants.” Ans. 9. However, the Examiner merely proposes modifications that could be made—but not that one of ordinary skill in the art would have made such modifications to arrive at the claimed invention. See Personal Web Techs., LLC, v. Apple, Inc., 848 F.3d 987, 993 (Fed. Cir. 2017). “[O]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015). We do not sustain the rejection of claims 1 and 28 under 35 U.S.C. § 103 over Sinha. We also do not sustain the rejection of claims 4, 5, 7, 8, 29, and 36, which depend from either claim 1 or claim 28. See 37 C.F.R. § 41.37(c)(1)(iv). Ground 5: Rejection of claim 41 as anticipated by Curnutt, as evidenced by Maor Claim 41 recites “[a]n activated carbon product comprising . . . Dead Sea salt.” Appeal Br. 60 (Claims App.). The Examiner relies upon Curnutt as evidence that the potassium chloride disclosed in Curnutt describes the claimed Dead Sea salt. Non- Final Act. 4 (citing Maor Table 1); see also Ans. 7. Appeal 2019-006991 Application 14/922,829 15 For the reasons set forth above supra in Ground 2 regarding claim 41, Appellant persuasively argues that Maor provides insufficient evidence that Curnutt’s potassium chloride teaches or suggests the claimed Dead Sea salt. See Appeal Br. 25. Furthermore, claim 41 recites “[a]n activated carbon product comprising biogenic activated carbon.” Id. at 60 (Claims App.). As set forth supra in Ground 1, the claimed “biogenic activated carbon” does not encompass Curnutt’s lignite based compositions. See Spec. ¶ 49; Curnutt 6:64–65. We do not sustain the rejection of claim 41 under § 103 over Curnutt, as evidenced by Maor. Ground 6: Rejection of claims 1, 4–8, 13–15, 24, 25, 28–31, 34, and 36–43 as obvious over Curnutt, as evidenced by Maor, Toomey, and Stencel The Examiner rejects claims 1, 4–8, 13–15, 24, 25, 28–31, 34, and 36–43 over Curnutt, as evidenced by Maor, Toomey, and Stencel. See Non- Final Act. 3–4. Because we consider the evidence insufficient to establish a prima facie case of obviousness with regard to recitations found in each of independent claims 1, 28, and 41, we need only address claims 1, 28, and 41. Claims 1 and 28 The Examiner finds Curnutt discloses each component of the claimed composition, but “teaches too much salt.” Id. at 4. The Examiner finds Curnutt teaches that “using less salt (and thus raising the carbon level to the claimed amount) is an obvious expedient to avid [sic, avoid] the problems of halogens discussed in col. 1–2” of Curnutt. Id.; see also Ans. 10 (finding Appeal 2019-006991 Application 14/922,829 16 that Curnutt “teaches in col. 1 line 57 et seq. that halogens are to be avoided.”). We have reviewed Curnutt’s cited disclosures. In our view, Appellant persuasively argues that the relied-upon passages “fail to disclose any ‘problems of halogens.’” Appeal Br. 50. We find that the rejection lacks the necessary “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” Kahn, 441 F.3d at 988. The Examiner’s conclusion that it would have been obvious to raise Curnutt’s carbon level to the claimed amount to avoid the problems of halogens lacks sufficient explanation and support in the record.
