Patent Owner and Appellant ____________ Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 Technology Center 3900 ____________ Before ROMULO H. DELMENDO, JEFFREY B. ROBERTSON, and RAE LYNN P. GUEST, Administrative Patent Judges. ROBERTSON, Administrative Patent Judge. DECISION ON APPEAL Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 2 Patent Owner Natural Alternatives, LLC. (“Patent Owner”) appeals under 35 U.S.C. §§ 134(b) and 315(a) (pre-AIA) the Examiner’s decision to reject claims 1–5, 8–10, 12, 15–19, 22–24, 26–35, 38–55, 58, 62–70, 72–90, 92, 95, 97, 99, 101–119, and 121–125.1 Third-Party Requester Univar USA, Inc. (hereinafter “Requester”) urges that the Examiner’s decision to reject these claims must be affirmed.2 Requester also appeals under 35 U.S.C. §§ 134(c) and 315(b) (pre- AIA) Requester appeals the Examiner’s decision to indicate claims 56, 57, 59–61, 120, and 126–131 as patentable, as well as the Examiner’s decision not to adopt certain rejections of claims 1, 4, 5, 26, 29-32, 34, 35, 38, 39, 43, 45-47, 51, 52, 54-63, 78-84, 99, 102, 117-120, and 126-131.3 Patent Owner urges that the Examiner’s decision not to adopt these rejections and confirm patentability of claims 56, 57, 59–61, 120, and 126–131 must be affirmed.4 We have jurisdiction under 35 U.S.C. § 6. As discussed infra, we AFFIRM-IN-PART the Examiner’s decision to reject the claims. We REVERSE the Examiner’s decision not to adopt the rejection of claims 119 and 120, which by operation of rule, results in the entering of a new ground of rejection of those claims. 1 See Patent Owner’s Appeal Brief 1 (filed January 3, 2017) (hereinafter “PO Appeal Br.”) Examiner’s Answer (mailed March 31, 2017) (hereinafter “Ans.”); Right of Appeal Notice (mailed September 16, 2016) (hereinafter “RAN.”). 2 See Requester’s Respondent Brief (filed March 15, 2017) (hereinafter “Req. Resp’t Br.”). 3 See Requester’s Appeal Brief filed December 29, 2016, hereinafter “JMI Appeal Br.,” 4, 19. 4 See Patent Owner’s Respondent Brief to Requester’s Appeal Brief filed January 30, 2017, hereinafter “PO Resp’t Br.” Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 3 STATEMENT OF THE CASE United States Patent 6,416,684 B1 (hereinafter the “’684 Patent”), which is the subject of the current inter partes reexamination, issued to Todd A. Bloomer on July 9, 2002, with 38 claims. A Request for Inter Partes Reexamination was filed by Requester on January 9, 2009. Patent Owner identifies related U.S. Patent 6,080,330, which was the subject of three merged ex parte reexamination proceedings 90/010,381, 90/011,454, and 90/011,713, and which was appealed to the Board (Appeal No. 2013– 009547). (PO Appeal Br. 1.) The Board affirmed the Examiner’s rejections, but the Board’s decision was reversed on appeal to the Court of Appeals for the Federal Circuit. (Id.; Decision on Appeal in Appeal No. 2013–009547 issued on May 30, 2014; Decision on Request for Rehearing Appeal No. 2013–009547 mailed April 28, 2015; In re Natural Alternatives, LLC, 659 Fed.Appx. 608 (Fed. Cir. 2016).) During the course of the reexamination proceeding Patent Owner has added 93 claims. Claims 1, 12, 15, 26, 46–55, 62, 92, 95, 97, 99, 101–103, 105, 117, 119–121, 123, 126, and 129 are independent. Claims 6, 7, 11, 13, 14, 20, 21, 25, 36, 37, 71, 91, 93, 94, 96, 98, and 100 have been canceled. (PO Appeal Br. 1.) The Examiner indicated that claims 56, 57, 59–61, and 126–131 are patentable. (RAN 83.) The ’684 Patent relates to a composition and method for preventing the accumulation of snow or ice on a surface or object, as well as a method of deicing surfaces or objects on which snow or ice has already accumulated. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 4 (Col. 1, ll. 5–9.) The composition includes desugared molasses and a second deicing component including a glycol or salt. (Col. 4, ll. 40–53.) Claim 1, which is illustrative of the appealed subject matter, reads as follows (with bracketing showing deletions relative to the originally issued claim): 1. A deicing composition comprising at least 20% by weight of desugared molasses and a second deicing component, said second deicing component being selected from the group consisting of ethylene glycol, di-ethylene glycol, [soluble potassium salts,] and the sodium, calcium, magnesium, and potassium salts of acetate, [chloride,] carbonate, and formate. (PO Appeal Br. 31, Claims App’x.) PATENT OWNER’S APPPEAL As identified by Patent Owner, the claims on appeal are subjected to 38 grounds of rejection, which can be found in Patent Owner’s Appeal Brief. (PO Appeal Br. 3; see also RAN 7–64.) Patent Owner contests each ground of rejection. (Id.) Rejection of claims 40–42 under 35 U.S.C. § 314(a) Claim 40, which we designate as a representative claim, depends from method claim 15. (Id. at 32, 34–35.) Claim 15 was amended during reexamination to delete certain members recited in the Markush group for the “second deicing component” in a manner not directly relevant to the issue raised in this rejection. (Id.; RAN 4). Claim 15, as recited in the original ’684 Patent, reads in pertinent part (’684 Patent, Col. 9, ll. 14-18): Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 5 A method for deicing an icy surface, comprising applying to said icy surface a deicing composition in an amount effective to reduce the level of ice on said surface, said composition comprising at least 20% by weight of desugared molasses and a second deicing component.... Claim 40 further recites that the method for deicing an icy surface includes “separately applying said desugared molasses and said second deicing component to said surface.” Claim 41 contains a similar limitation. Claim 42 depends from claim 41. The Examiner rejected claims 40–42 as being broader than the originally patented claims, which, as seen in the text of original claim 15, did not require a method where the desugared molasses and second deicing component are applied separately to a surface. (RAN 7.) Patent Owner contends that the ’684 Patent discloses that the “applying” step may include separate application of the components, such that claims 40–42 are narrower in scope than the limitations at issue in originally issued claim 15. (PO Appeal Br. 4, citing ’684 Patent, Col. 6, ll. 47–54.) Requester contends that the original claims cannot cover both simultaneous and separate application of the composition because there is no evidence that the two components, when separately applied, will come together to form a composition with at least 20% desugared molasses, as recited in claim 15. (Req. Resp’t Br. 4.) Requester argues that because of the presence of other components such as water and ice, it is unclear that a composition having at least 20% desugared molasses will be obtained. (Id.) Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 6 The issue with respect to this rejection is whether the Examiner erred in determining that new claims 40–42 enlarge the scope of the originally issued claims of the ’684 Patent. We look to the ’684 Patent Specification to ascertain what the Inventor meant by “applying.” The ’684 Patent enlightens one skilled in the relevant art that (col. 6, ll. 51–55): The composition may be “applied” by applying the components separately, such as by first applying salt and then applying desugared sugar beet molasses and optionally other components such as the anti- skid agent. The ’684 Patent originally issued with claim 15 reciting a method comprising “applying” a deicing composition including at least 20% by weight of desugared molasses and a second deicing component to an icy surface. As reproduced above, the ’684 Patent expressly discloses that the term “applied” may include separate application of the components of the composition, and, therefore, both simultaneous and separate applications are implicit in the original claim language read in light of the Specification. That is, the ’684 Patent Specification reasonably informs a person skilled in the art that the term “applying” in claim 15, as originally issued, encompassed both simultaneous and separate application of the components of the composition. As to Requester’s contention that it is unclear whether a composition containing 20% by weight desugared molasses would be formed, we do not agree. When reading the claims in context, one of ordinary skill in the art would have understood that the composition amounts are based on the “dry weight” of the composition, as evidenced by dependent claims 18 and 19. Moreover, while the composition in claim 15 Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 7 is open to other components as a result of the “comprising” transitional phrase, there is no indication that one of ordinary skill in the art would have considered materials already existent on the surface upon which the components are to be applied to be part of the “deicing composition” that is applied “to said icy surface,” as recited in claim 15. Accordingly, we reverse the Examiner’s rejection of claims 40–42 under 35 U.S.C. § 314(a). Rejection of claims 40–42, and 130 under 35 U.S.C. § 112, fourth paragraph The Examiner also rejected claims 40–42 under 35 U.S.C. § 112, fourth paragraph for failing to further limit claim 15, because the Examiner had determined that claim 15 did not cover a method including applying desugared molasses and a second deicing component separately. (RAN 9.) For the reasons discussed above with respect to the rejection of claims 40– 42 under 35 U.S.C. § 314(a), we reverse the Examiner’s rejection of claims 40–42. New claim 130 depends from new claim 129. (PO Appeal Br. 45.) Claim 129 recites a method for preventing the formation of ice on an outdoor surface by applying a composition comprising at least 20% by weight desugared molasses, said desugared molasses derived from the Steffen process . . ..” (Id.) Claim 130 recites that the method “further including the step of deriving the desugared molasses from molasses via the Steffen process.” (Id.) Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 8 The Examiner determined that claim 130’s process step does not further limit claim 129 because claim 129 already recites that the desugared molasses is derived from the Steffen process. (RAN 9.) Patent Owner contends that claim 129 does not require the step of deriving the desugared molasses from molasses via the Steffen process, only using a product derived from the Steffen process, such that claim 130 further limits claim 129. (PO Appeal Br. 6.) We agree with Patent Owner. Claim 130 positively recites a step that is not present in claim 129, the actual step of deriving the desugared molasses via the Steffen process. Although claim 129 recites “said desugared molasses derived from the Steffen process,” we interpret that language as a product-by-process limitation defining the “desugared molasses” that could be met by any “desugared molasses” that is chemically and structurally indistinguishable from that derived from the Steffen process—not a positive step actually required by the claim. Accordingly, claim 130 further limits claim 129. Therefore, we reverse the Examiner’s rejection of claim 130 under 35 U.S.C. § 112, fourth paragraph. Rejection of claims 39, 44–47, 58, and 119 under 35 U.S.C. § 112, first paragraph as failing to comply with the written description requirement Claim 39, which was added during reexamination depends from composition claim 1, and recites that the deicing composition includes “between 40 and 70% by weight desugared molasses.” Claims 44–47 are method claims or composition claims reciting the same weight range for desugared molasses. Claim 58 is rejected as dependent from claim 46. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 9 Claim 119 is a method claim reciting a deicing composition having “70% by weight of desugared molasses.” The Examiner found that the Specification of the ’684 Patent does not support a deicing method or composition comprising between 40 and 70% by weight desugared molasses. (RAN 8.) In particular, the Examiner found that Example 1 of the ’684 Patent contains two compositions that are relevant to the claimed range, one having 70% desugared sugar beet molasses and one having 40% desugared sugar beet molasses, where neither composition specifies whether the percentages are by weight. (Id.) In addition, the Examiner found that the claims are broader than the specific Example 1 compositions because they are not limited to magnesium chloride as the second deicing component. (RAN 9.) Patent Owner contends that if the weight percentages in Example 1 of the ’684 Patent are taken as calculated by weight, then the claim language is directly supported by Example 1. (PO Appeal Br. 4.) Patent Owner argues also that if the percentages in Example 1 are taken as by volume, Patent Owner has provided calculations based on density disclosed in the ’684 patent (col. 7, l. 13) to show that the claimed weight percentages are still disclosed. (Id.) Patent Owner contends further that the ’684 Patent discloses that water may be added to any embodiment, which would necessarily decrease the concentration of desugared molasses in the overall composition, and include percentages between 40% and 70% by weight. (PO Appeal. Br. 5.) Patent Owner does not set forth separate arguments for claim 119. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 10 Requester contends that claims 39, 44–47, and 58 require that the second deicing component be a salt, which is a solid, and as such cannot encompass the “solution,” described in Example 1. (Req. Resp’t Br. 4.) Accordingly, the issue with respect to this rejection is whether the Examiner erred in finding that the ’684 Patent does not provide adequate written descriptive support for a composition having between 40% and 70% by weight, or exactly 70% by weight, desugared molasses, as recited in the claims. To satisfy the written description requirement, a patent applicant must “convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention.” Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed. Cir. 1991) (emphasis omitted). Literal support for a claim limitation is not required under the first paragraph of 35 U.S.C. § 112. Id. at 1563; In re Gosteli, 872 F.2d 1008, 1012 (Fed. Cir. 1989). Upon review of the ’684 Patent, we agree with Patent Owner, that the recited ranges of desugared molasses including 40 to 70% by weight are conveyed with reasonable clarity to those skilled in the art. In this regard, originally issued claim 1 of the ’684 Patent recites that the desugared molasses is present in “at least 20% by weight,” which informs the skilled artisan that the percentages of desugared molasses are expressed as weight percentages. (’684 Patent, col. 8, ll. 32–38.) Also, we observe that the ’684 Patent discusses the concentrations of the second deicing component in percentages by weight. (Col. 6, ll. 19–29.) As a result, we are of the view that one skilled in the art would have readily understood that the 70% and Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 11 40% desugared molasses amounts disclosed in Example 1 are expressed in weight percentages. (col. 7, ll. 35–55.) As to the Examiner’s position that the percentages of desugared molasses disclosed in Example 1 are relevant only to combinations of desugared sugar beet molasses with magnesium chloride, we do not agree. Neither the Examiner nor the Requester directs us to concrete evidence or technical reasoning that the use of magnesium chloride is essential for the calculated 40% and 70% by weight data points. The ’684 Patent specifically discloses several other deicing agents that may be used as alternative second deicing components, whether provided as solid salt or solution as well as that the amounts of the second deicing composition may vary widely, depending on the particular composition. (’684 Patent, col. 4, ll. 42–52; col. 6, ll. 19-28 (generally citing maximum amounts for additional deicing agents while contemplating that even “higher concentrations are possible”); col. 8, ll. 32–38, 47–50.) Accordingly, we reverse the Examiner’s rejection of claims 39, 44– 47, 58, and 119 under 35 U.S.C. § 112, first paragraph. Claim 62 under 35 U.S.C. § 102(b) as anticipated by Daly5,6 Claim 62 was added during reexamination and is reproduced below (PO Appeal Br., Claims App’x 38): 5 US Patent 5,639,319, issued June 17, 1997. 6 The Federal Circuit’s holding that Daly is non-analogous art (Natural Alternatives, 659 Fed.Appx. at 614) further discussed infra is not relevant to an anticipation rejection. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 12 62. A deicing composition comprising greater than 25% by weight of desugared molasses and further comprising a second deicing component selected from the group consisting of the sodium, calcium, magnesium, and potassium salts of chloride. The Examiner found that Daly discloses a composition comprising desugared sugar beet molasses having from 35–85% by weight solids and containing up to 50% by weight of calcium or magnesium chloride. (RAN 60.) The Examiner found that a composition comprising calcium or magnesium chloride in such amounts would necessarily contain greater than 25% by weight desugared molasses. (Id.) Patent Owner contends that the Examiner’s logic is flawed because Daly does not expressly disclose that the composition includes only desugared molasses and calcium or magnesium chloride. (PO Appeal Br. 24–25.) The issue with respect to this rejection is whether one of ordinary skill in the art would have appreciated that Daly discloses compositions including desugared molasses within the range recited in claim 62. We agree with the Examiner that claim 62 is anticipated by Daly. Daly discloses a composition that combines desugared molasses with inorganic salts, where the salts are present in an amount “less than about fifty percent (50%) by weight.” (Daly, col. 3, ll. 4–7.) Daly discloses antifoam agents and enhancers to improve smell that may be added to the composition. (Col. 3, ll. 25–37.) Because these components are disclosed as “preferred” but not required (id.), Daly expressly teaches a composition with only desugared molasses and an inorganic salt. Even if Daly’s disclosure cannot be considered to be explicit, “it is proper to take into account not only Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 13 specific teachings of the reference but also the inferences which one skilled in the art would reasonably be expected to draw therefrom” in assessing whether a claim is anticipated. In re Preda, 401 F.2d 825, 826 (CCPA 1968). Thus, Daly discloses that desugared molasses is present in amounts greater than 50% by weight, which is within the claimed range of greater than 25% by weight. Accordingly, Patent Owner’s arguments are not persuasive. As a result, we affirm the Examiner’s rejection of claim 62 as anticipated by Daly. Rejection of Claims 1–5, 8–10, 12, 15–19, 22–24, 39, 44, 46, and 47 under 35 U.S.C. § 103(a) as obvious over Johnston,7 Longworth,8 and Gall I9 The Examiner found that Johnston discloses methods of inhibiting corrosion caused by chloride ions in conventional deicers, such as calcium and magnesium chloride, by adding corrosion inhibitors to the deicer. (RAN 16.) The Examiner found that Johnston does not disclose a deicing composition comprising a desugared molasses. (Id.) The Examiner found that Longworth discloses that ethylene glycol/water systems, which Johnston teaches as another conventional deicer, are also known to be corrosive to metal surfaces, and thus ethylene glycol is one of Johnston’s further described “other corrosive deicers.” (Id.) The Examiner found that Gall I 7 US Patent 5,071,579, issued December 10, 1991. 8 US Patent 4,689,201, issued August 25, 1987. 9 CA 2 287 582 A1, published April 27, 2000. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 14 discloses that desugared molasses is useful as a corrosion inhibitor in chloride-based deicers or other deicing materials sprayed on roads where the desugared molasses has a solid content greater than 45 percent by volume and may comprise 1 to 50 percent by volume of the composition. (RAN 16– 17.) The Examiner concluded that it would have been obvious to have used the desugared molasses in the amounts disclosed in Gall I in a deicing composition as an alternative corrosion inhibitor to that disclosed in Johnston to arrive at the amount of desugared molasses recited in the claims. (RAN 17–18.) Patent Owner contends that Johnston, in addition to lacking a teaching of desugared molasses, does not disclose that the corrosion inhibitor is present in amounts greater than 5 percent by weight. (PO Appeal Br. 12.) Patent Owner argues that the rejection does not account for how the teachings of Gall I would be merged with Johnston in order to arrive at the claimed amount of desugared molasses. (Id. at 12–13.) Requester contends that Johnston provides appropriate amounts when using a different corrosion inhibitor than desugared molasses, and as such Gall I provides the proper amount of desugared molasses when it is to be used as an alternative corrosion inhibitor. (Req. Resp’t Br. 9.) In addition, Requester argues that the desugared molasses does not have to be a substitute for the corrosion inhibitor disclosed in Johnston, but may be added in addition to Johnston’s corrosion inhibitor. (Id.) Accordingly, the issue with respect to this rejection is whether it would have been obvious to have used the desugared molasses in Gall I as a Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 15 corrosion inhibitor with Johnston’s corrosive conventional deicers in the amounts recited in the claims. Johnston discloses a corrosion inhibiting system for inhibiting corrosion caused by corrosive deicers, which deicers include sodium chloride, calcium chloride, and “other corrosive deicers or any other products causing or susceptible of causing similar corrosions.” (Col. 1, ll. 10–18.) Johnston discloses that conventional deicers include glycols, calcium chloride, magnesium chloride, “and in general other deicers that are generally available.” (Col. 3, ll. 3–11.) Johnston discloses that the deicing composition comprising at least 50% by weight, preferably at least 70% by weight of a deicer. (Col. 3, ll. 12–14.) Johnston discloses that the corrosion inhibitor is sodium fluorophosphates, which is present in an amount of at least 0.25% by weight, and preferably 2–5% by weight of the system. (Col. 4, ll. 13–17.) Gall I discloses desugared sugar beet molasses as a corrosion inhibitor in chloride-based deicers or other deicing materials sprayed on the roads. (P. 3, ll. 13–20.) Gall I discloses that the chloride-based deicers include calcium and magnesium chloride. (Id.) Gall I discloses that the desugared molasses may be added in amounts of from 1 to 50 percent by volume to a chloride-based deicer solution having a solid content of 45 to 65 percent by volume. (Pages 3, l. 30 – p. 4, l. 2.) Gall I additionally discloses that desugared molasses improves the solubility of other inhibitors in chloride brine by acting as a carrying agent. (P. 4, ll. 10–15.) As pointed out by the Examiner and Requester, Gall I discloses amounts of desugared molasses that overlap or encompass the amounts Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 16 recited in the claims. Here, we observe that Patent Owner has not argued or presented persuasive evidence that the percent by volume of desugared molasses disclosed in Gall I would not include amounts in percent by weight within the claims. We do not subscribe to Patent Owner’s view that a skilled artisan would only consider adding up to 5% by weight of corrosion inhibitor to the conventional corrosive deicers of Johnston where the skilled artisan would understand similar anti-corrosive effect with from 1 to 50 percent by volume of desugared molasses with the same conventional corrosive deicers. Johnston does not disparage using amounts of alternative corrosion inhibitor above 5%. (See Col. 4, ll. 13–17.) Gall I would have informed one of ordinary skill in the art that when applying desugared molasses as a corrosion inhibitor, amounts including those recited in the instant claims would have been used successfully. In addition, and importantly for all of Patent Owner’s arguments directed to the precise concentration of desugared molasses and a second deicing component recited throughout the claims, “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation.” In re Aller, 220 F.2d 454, 456 (CCPA 1955). If a routine variable change causes an unexpected effect, the claimed subject matter will be unobvious under the law if the claimed range is critical to obtaining unexpected beneficial results. See In re Boesch, 617 F.2d 272, 276 (CCPA 1980); In re Woodruff, 919 F.2d 1575, 1578 (Fed. Cir. 1990). In this regard, we observe that the ’684 Patent does not assign any criticality to the amounts of the composition Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 17 components. (’684 Patent, col. 6, ll. 47–51, “[t]he composition is applied to a surface in any amount effective for its intended purpose, i.e., as a deicing agent or as an anti-icing agent. The exact amounts applied will be determined by persons of skill in the art, depending on the exact composition chosen.”) Alternatively, we observe that Gall I discloses that desugared molasses can be used in conjunction with “chloride-based de-icers” particularly calcium chloride, sodium chloride, potassium chloride or magnesium chloride, “or other de-icing materials sprayed on the roads to reduce the corrosion rate of metallic surfaces of motor vehicles, and structural roadway components such as bridges, signs and guardrails.” (Gall I, p. 3, ll. 13–16, emphasis added.) “[O]ther de-icing materials” would include the conventional deicers such as ethylene glycol systems disclosed in Johnston (col. 2, l. 67– col. 3, l. 8), which Longworth discloses are also corrosive (Col. 3, ll. 12–16.) Thus, one of ordinary skill in the art would have used the desugared molasses of Gall I with the conventional deicers disclosed in Johnston as instructed by the teachings of Gall I. Accordingly, we are not persuaded by Patent Owner’s arguments that applying the amounts of desugared molasses recited in the claims would not have been obvious in view of the prior art of record. Regarding claims 46 and 47, Patent Owner similarly argues that the amounts of the corrosion inhibitor taught in Johnston (up to 5% by weight) teaches away from the amounts of desugared molasses taught by Gall I (from 1 to 50 percent by volume) which the Examiner determined renders obvious the ranges recited in claims 46 and 47 of between 40 and 70% by Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 18 weight. (PO Appeal Br. 13.) We are not persuaded by these arguments for the reasons discussed above. We emphasize again that Johnston’s disclosure of certain amounts for a different corrosion inhibitor does not constitute a teaching away where Johnston does not disparage using a different corrosion inhibitor in amounts above 5%. Regarding claim 12, Patent Owner argues that the Examiner has not provided a prima facie case of obviousness with respect to a step of mixing the desugared molasses with water. (PO Appeal Br. 13.) We disagree. The Examiner specifically references Gall I (page 3, line 30 – page 4, line 2) in the course of rejecting claim 12. (RAN 17.) Gall I discloses that chloride-based deicing solutions are administered in water. (Gall I, p. 3. ll. 21–22.) Indeed, as discussed above, Gall I discloses that desugared molasses is used in conjunction with chloride brine. (P. 4, ll. 10– 15.) In addition, Johnston also discloses water as a solvent or diluent for corrosion inhibitors. (Johnston, col. 4, ll. 32–44.) On the record before us, Patent Owner has directed us to no error in the Examiner’s rejection of claim 12. Secondary Considerations “Objective indicia of nonobviousness play a critical role in the obviousness analysis. They are not just a cumulative or confirmatory part of the obviousness calculus but constitute independent evidence of nonobviousness.” Leo Pharmaceutical Products, Ltd. v. Rea, 726 F.3d 1346, 1358 (Fed. Cir. 2013) (internal quotations and citation omitted). Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 19 “Objective indicia can be the most probative evidence of nonobviousness in the record, and enables the court to avert the trap of hindsight.” Id. Thus, as part of the obviousness analysis, we consider the evidence of patentability presented by Patent Owner, and weigh that evidence against the evidence in favor of obviousness discussed above. Patent Owner relies on the First Bloomer Declaration,10 which according to Patent Owner describes “successful licensing of the ’684 Patent.” (PO Appeal Br. 26.) Patent Owner also relies on the Second Bloomer Declaration,11 which allegedly establishes that products sold under the trademark GEOMELT are anti-icing/deicing fluids “produced under the ’684 Patent” and contains evidence of industry praise, professional approval, and unexpected results. (PO Appeal Br. 26–27.) Patent Owner argues that the First and Second Bloomer Declarations provide evidence of a nexus between the claimed invention and the commercial success. (PO Appeal Br. 27.) Patent Owner also cites to articles that discuss use of GEOMELT on city roads in order to show significant commercial success. (PO Appeal Br. 27; Evidence App’x E-I.) Patent Owner contends that the report “Beet juice beats salt”12 provides evidence of industrial praise, professional approval, and unexpected results. (PO Appeal Br. 27.) 10 Declaration of Todd A. Bloomer executed on October 27, 2009. (PO App. Br., Evidence App’x C.) 11 Declaration of Todd A. Bloomer executed on January 21, 2014. (PO App. Br., Evidence App’x D.) 12 “Beet juice beats salt,” NEWSCHANNEL 3, February 27, 2008. (App. Br. Ev. App’x E.) Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 20 The Federal Circuit discussed similar evidence presented by Patent Owner with respect to secondary considerations in In re Natural Alternatives, noting that the Board found the evidence lacked a nexus where Patent Owner’s commercial success was based on the same advantages of using desugared beet molasses that were taught in the prior art. Natural Alternatives, 659 Fed.Appx. at 615. The Federal Circuit, in view of the decision that Zdzislaw did not disclose the desugared beet molasses recited in the claims, rejected the lack of nexus argument, stating “we conclude that the unrebutted objective indicia in the record confirm that the claimed invention would not have been obvious.” Id. In this case, the Examiner similarly determined, inter alia, that the prior art already taught that desugared molasses was useful as a corrosion inhibitor in deicing materials, citing to Gall I, such that there was no nexus between the evidence and the novel aspects of the claims. (RAN 80.) We are not persuaded that the evidence presented by Patent Owner outweighs the evidence in favor of obviousness. In this regard, as the Examiner points out, Gall I discloses a combination of salt and desugared molasses as discussed above. Moreover, Gall I discloses the use of desugared molasses as a corrosion inhibiting component in deicing materials. (Gall I, p. 3, ll. 13–16.) Gall I further teaches that desugared molasses is “environmentally friendly, agriculturally-derived material” and is “non-toxic.” (Gall I, p. 2, l. 21–27.) Similarly, the evidence submitted by Patent Owner emphasizes that the combinations of desugared molasses and salt is “less corrosive to metal” (“City to Use Environmentally Friendly Road Salt Mixture,” City of Wheaton Illinois, November 6, 2008, PO Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 21 Appeal Br., Evidence App’x F) and “can reduce the amount of corrosion- causing salt used to treat streets” (“Topeka to use beet juice mix to treat roads,” Topeka Capital-Journal, November 11, 2008, p. 2, PO Appeal Br., Evidence App’x H). Thus, the evidence of record is indicative of well- known facts from the art, namely that a salt-desugared molasses mixture works better than salt alone because it has corrosion inhibiting benefits. As such, the evidence is insufficient to establish a nexus between the novel aspects of the claimed subject matter and the evidence presented. See Tokai Corp. v. Easton Enters, Inc., 632 F.3d 1358, 1369 (Fed. Cir. 2011). The same reasoning applies to all of the rejections further discussed below in which the Examiner relies on the teachings of Gall I. Accordingly, the evidence in favor of obviousness outweighs the evidence in favor of nonobviousness. As a result, we affirm the Examiner’s rejection of claims 1–5, 8–10, 12, 15–19, 22–24, 39, 44, 46, and 47 under 35 U.S.C. § 103(a) as obvious over Johnston, Longworth, and Gall I. Claims 8-10 and 22-24 as obvious over Johnston, Longworth, Gall I, and Janke;13 Claims 40-42 as obvious over Johnston, Longworth, Gall I, and Lin14 Patent Owner does not present separate arguments with respect to the rejections of claims 8–10, 22–24, and 40–42. (PO Appeal Br. 13.) Accordingly, we affirm the Examiner’s rejection of claims 8–10, 22–24, and 13 US Patent 5,635,101 issued June 3, 1997. 14 US Patent 4,824,588 issued April 25, 1989. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 22 40–42 for similar reasons as discussed above with respect to the rejection based on Johnston, Longworth, and Gall I. Claims 26–35, 38, and 45 as obvious over Johnston, Longworth, Gall I, and Janke Regarding independent claims 26 and 45, Patent Owner similarly argues that the amount of corrosion inhibitor taught in Johnston (up to 5% by weight) teaches away from the amount of desugared molasses disclosed in Gall I (from 1 to 50 % by volume), which the Examiner determined renders obvious the amounts of desugared molasses recited in claim 26 (at least 20% by weight) and claim 45 (between 40 and 70% by weight). (PO App. Br. 14.) We are not persuaded by Patent Owner’s arguments for the reasons discussed above. Claims 1–5, 12, 15–19, 39, 44, 46–50, 106–115 as obvious over Skankowiak I,15 Gall I, and Daly; claims 40–42 as obvious over Stankowiak I, Gall I, and Lin; claims 43 and 55 as obvious over Stankowiak I, Gall I, and Blake16 The Examiner adopted the rejection proposed by Requester in Requester Comments filed November 25, 2009 and February 19, 2014. (RAN 10.) The Examiner found that Stankowiak I discloses a deicing composition containing 87 to 99.45% by weight of alkali metal acetate and/or alkali metal formate deicer and a light metal corrosion inhibitor 15 US Patent 6,059,989 issued May 9, 2000. 16 US Patent 4,594,076 issued June 10, 1986. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 23 comprising from 0.5 to 10% by weight of an alkali metal silicate and from 0.05 to 3% by weight of an alkali metal phosphate, where the amounts of the three components, with or without further advantageous components, in the aqueous deicing composition can be varied within wide limits. (RAN 11.) The Examiner found that Stankowiak I fails to disclose a deicing composition comprising a desugared molasses. (Id.) The Examiner found that Gall I discloses that typical inhibitors, such as phosphates and silicates (as disclosed in Stankowiak I) have had limited success due to certain disadvantages including solubility and toxicity concerns. (RAN 11.) The Examiner found that Gall I discloses that desugared molasses is useful as a corrosion inhibitor in chloride-based deicers or other deicing materials sprayed on roads where the desugared molasses has a solid content greater than 45 percent by volume and may comprise 1 to 50 percent by volume of the composition. (RAN 11–12.) The Examiner found that Daly discloses a desugared beet molasses containing 35–89% by weight of solids, a density of 8.0 to 11.6 lbs per gallon (0.95 to 1.4 kg/liter), and that contains 18% protein, 15% sugars, 18% carbohydrates, and 16% potassium salts by weight. (RAN 12.) The Examiner concluded that it would have been obvious to have used the desugared molasses in the amounts disclosed in Gall I in a deicing composition as an alternative corrosion inhibitor to that disclosed in Stankowiak I to arrive the amount of desugared molasses recited in the claims. (RAN 12.) The Examiner concluded also that it would have been obvious to use a desugared beet molasses with the properties disclosed in Daly, as Daly discloses a desugared beet molasses prepared using the Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 24 Steffen process, which the ’684 Patent acknowledges is a known method of obtaining suitable desugared molasses. (RAN 12, citing ’684 Patent, col. 5, ll. 45–58.) Patent Owner contends that Daly is non-analogous art, relying on, inter alia, the Federal Circuit’s decision, which was entered before the Examiner’s Answer and Right of Appeal Notice, holding that Daly was not analogous art because the tire ballast that is the subject of Daly is not reasonably pertinent to the problem of deicing or preventing the accumulation of ice on road surfaces. (PO App. Br. 7–8; Natural Alternatives, 659 Fed.Appx. at 614.) Patent Owner contends also that Stankowiak I discloses that the acetate and/or formate deicer is used over a narrow and high range of 87–99.5%, which does not support the Examiner’s finding that the amounts of components in the deicing composition may be varied within wide limits, and is different from the claimed amount of desugared molasses of at least 20% by weight. (PO App. Br. 8–9.) Requester contends that Stankowiak I discloses that the amounts of the components can vary within wide limits (col. 2, ll. 45–49 ) and that Stankowiak I discloses acetate and or formate deicers in amounts of 45 to 60 % by weight. (Req. Resp’t Br. 6.) The issues with respect to this rejection are whether Daly is analogous art, and whether it would have been obvious to arrive at the composition recited in the claims, and in particular the amount of desugared molasses recited in view of Stankowiak I and Gall I. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 25 Analogous Art For the reasons expressed in the Federal Circuit’s Decision, we agree with Patent Owner that Daly is non-analogous art. However, we observe that Daly, in this case, is only cited in order to reach certain limitations of the claims relating to the specific properties of desugared beet molasses recited in claims 3, 17, 28, 48, 50, 106–115. Indeed, the Right of Appeal Notice indicates that the rejection was adopted as proposed by Requester, who relied on Daly in the event that “the weight percent of solids in desugared molasses is not obvious in view of Gall I.” (RAN 10, citing Comments filed November 25, 2009, pp. 15–18; Third Party Requester’s Comments to Patent Owner’s Comments on Action Closing Prosecution filed November 25, 2009, p. 18.) Thus, Patent Owner’s argument regarding Daly is only persuasive to warrant reversal of the Examiner’s rejection as applied to claims 3, 17, 28, 48, 50, and 106–115. Obviousness As discussed above, Daly is only relied upon for disclosing particular characteristics and synthesis procedures for the desugared molasses recited in claims 3, 17, 28, 48, 50, and 106–115. Regarding Patent Owner’s argument that the amounts of components disclosed Stankowiak I do not support the Examiner’s findings, we are not persuaded. As pointed out by the Examiner, Stankowiak I specifically discloses that the amounts of the three components may be varied “within wide limits.” (col. 2, ll. 45–49). Furthermore, in view of the amounts of desugared molasses disclosed in Gall I (p. 3, l. 30 – p. 4, l. 2), one of Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 26 ordinary skill in the art, in considering the prior art as whole, would not have been limited to the amounts of deicer disclosed in Stankowiak I. Moreover, because Gall I addresses the drawbacks pertaining to silicate and phosphate inhibitors taught by Stankowiak I and teaches using desugared molasses instead (Gall I, p. 1, ll. 10–12, 25–28), one of ordinary skill in the art would have had a specific reason to use the desugared molasses of Gall I in the amounts taught therein as an alternative corrosion inhibitor to those taught by Stankowiak I. Accordingly, we are not persuaded that the Examiner erred in rejecting claims 1, 2, 4, 5, 15, 16, 18, 19, 39, 44, 46, 47, and 49 over the combination of Stankowiak I and Gall I. Regarding claims 40–42, 43, and 55, Patent Owner does not set forth separate arguments for claims 40–42, 43, and 55, but rather relies on the same arguments set forth above made for claim 15, from which claims 40– 42, 43, and 55 depend. (PO App. Br. 9, 23.) Accordingly, we affirm the Examiner’s rejection for the same reasons as discussed above. Claims 1, 2, 73, and 86 over Gall I and Stankowiak I In rejecting claims 1, 2, 73, and 86 over the combination of Gall I and Stankowiak I, the Examiner found that Gall I discloses deicers including desugared molasses in combination with conventional chloride based deicers or other deicing materials sprayed on the roads, but does not disclose sodium formate as a known deicer, as recited in claims 73 and 86. (RAN 40.) The Examiner found that Stankowiak I discloses combining conventional deicing agents including sodium formate with corrosion inhibitors. (RAN 41.) The Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 27 Examiner concluded that it would have been obvious to form a deicer composition having improved corrosion resistance comprising a sodium formate deicer of Stankowiak I and the desugared molasses of Gall I, and that one of ordinary skill in the art would have been able to select the optimum or workable concentration range of each component by routine experimentation. (RAN 41.) For claims 1 and 2, Patent Owner relies on similar arguments directed to the amounts of corrosion inhibitor taught by Stankowiak I and Gall I as discussed above with respect to the rejection of claim 1 over Stankowiak I in view of Gall I. (PO Appeal Br. 19.) We are not persuaded for the reasons discussed above. Regarding claims 73 and 86, Patent Owner contends that the Examiner does not allege that Gall I or Stankowiak I disclose the specifically recited weight percentage of sodium formate recited in the claims (55% by weight). (PO Appeal Br. 19.) In this regard, Patent Owner contends that Stankowiak I discloses only the alkali metal formate deicer, and discloses the deicer in amounts that are different from the amounts recited in the claims. (Id.) Requester contends that Patent Owner does not consider the combination of references and that the test for obviousness is not whether the features of the secondary reference may be bodily incorporated in the structure of the primary reference. (Req. Resp’t Br. 14.) We agree with the Examiner that one of ordinary skill in the art, when formulating a composition including sodium formate and desugared molasses from the teachings of Stankowiak I and Gall I, respectively, would Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 28 have determined optimal or workable amounts of sodium formate by routine experimentation, including the amounts recited in the claims. Aller, 220 F.2d at 456. Patent Owner has not directed our attention to persuasive evidence that the amounts of sodium formate recited in the claims are in any way critical to achieving a specific result. Accordingly, we affirm the Examiner’s rejection of claims 1, 2, 73, and 86. Claims 50, 117, 118, 123–125 as obvious over Daly; Claim 104 as obvious over Daly and Hicks;17 Claims 62, 63, and 105 as obvious over Daly and Hull18 Because, as discussed above, the Federal Circuit has held that Daly is nonanalogous art (Natural Alternatives, 659 Fed.Appx. at 614) and because, inconsistent with the court’s ruling, the Examiner relies on the teachings of Daly as key evidence in rejecting each of these claims as obvious, we reverse the Examiner’s rejections. Claims 8–10, 22, 24, 26–35, 38, and 45 as obvious over Stankowiak I, Gall I, and Janke Regarding claims 8–10 and 22–24, Patent Owner contends that because these claims depend from claims 1 and 15, which are only rejected in combination with Daly, this rejection should be reversed because Daly is non-analogous art. (PO App. Br. 9.) 17 US Patent 2,884,039 issued April 28, 1959. 18 US Patent 5,364,463 issued November 15, 1994. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 29 As pointed out above with respect to claims 1 and 15 and further by the Examiner, claims 1, 8–10, 15, and 22–24 do not define the properties of the desugared molasses for which Daly was relied upon, and thus Daly is not necessary to the rejection of claims 1, 8–10, 15, and 22–24. (RAN 69.) Accordingly, Patent Owner’s arguments are not persuasive. Regarding claims 26 and 45, Patent Owner contends that Stankowiak I in combination with Gall I does not render obvious the amount of desugared molasses in the claims (at least 20% by weight and between 40 and 70 % by weight, respectively) for similar reasons that we found unpersuasive above with respect to claims 1–5, 12, 15–19, 39, 44, 46–50, 106–115, in particular, arguing that the amount of deicing component disclosed by Stankowiak I cannot be varied within wide limits, but is limited to a narrow and high range that would preclude the amount of desugared molasses recited in the claims. (PO App. Br. 9.) As discussed above, this argument is not persuasive because it does not address the teaching in Gall I of an amount of desugared molasses (1–50%) that renders the recited range obvious. Accordingly, we affirm the Examiner’s rejection of claims 8–10, 22– 24, 26–35, 38, and 45 as obvious over Stankowiak I, Gall I, and Janke. Claims 26–35, 38, and 45 as obvious over Gall I and Janke Similar to the discussion in detail above, the Examiner found that Gall I discloses desugared molasses in amounts of 1–50% by volume of the composition. (RAN 19.) The Examiner found that Janke discloses sand, river gravel, cinders, sawdust, or other skid-reducing grit are used with Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 30 deicing compositions and applied to surfaces to keep free of snow and ice. (RAN 20.) The Examiner concluded that it would have been obvious to pretreat an outdoor surface taught by Janke with a deicing composition as taught by Gall I in order to prevent the adherence of snow and ice to the surfaces. (RAN 20.) Even though the Examiner does not so state in the rejection, Patent Owner contends that, because Gall I discloses the desugared molasses is present in 1–50% by volume, the Examiner must be relying on calculations based on the density disclosed in Daly to arrive at the amounts recited in rejected claims of at least 20% by weight desugared molasses. (PO Appeal Br. 13.) According to Patent Owner this would be error because Daly is non-analogous art. (Id.) For claims 29 and 30, Patent Owner argues that the dry weight percentages of 5–80% and 10–60%, respectively, are not addressed in the rejection, and thus, a prima facie case of obviousness is lacking. We are not persuaded by Patent Owner’s arguments for the same reasons as discussed above with respect to the rejection of claims 1–5, 8–10, 12, 15–19, 22–24, 39, 44, 46, and 47 including Gall I. That is, Patent Owner has not directed our attention to sufficient evidence rebutting the Examiner’s reasonable finding that the weight percentages recited in the claims overlap or encompass the volume percentages recited in the prior art. Moreover, as discussed above, it is not inventive to determine optimal or workable amounts by routine experimentation, and Patent Owner has not shown that the particular amounts recited in the claims are critical to obtaining unexpectedly beneficial results. Aller, 220 F.2d at 456. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 31 As to the alleged reliance on Daly for converting the amounts from volumetric to weight percentages, there is no indication that the Examiner relied on Daly for such a conversion. As discussed above, Patent Owner had not argued or provided persuasive evidence identifying reversible error in the Examiner’s finding that the volume percentage range disclosed in Gall I would, when converted to weight percentages, overlap or encompass the weight percentages recited in the claims. Claims 1–5, 12, 15–19, 39, 44, 46–55, and 116 over Public Works,19 Gall I, Stankowiak I, Daly Patent Owner contends, inter alia, that Daly is nonanalogous art, and that Public Works describes only a concentrated fermentation byproduct, which is not the desugared molasses of the claimed invention. (PO Appeal Br. 14–15.) We agree with Patent Owner, because, as discussed above, the Federal Circuit determined that Daly is nonanalogous art. Natural Alternatives, 659 Fed.Appx. at 614. Moreover, the Federal Circuit determined that Public Works does not disclose the desugared molasses products in the ’330 Patent, which the ’684 Patent claims to be a divisional, and thus contains the same disclosure. Natural Alternatives, 659 Fed.Appx. at 615. The Examiner’s failure to take account of the court’s rulings constitutes reversible error. Accordingly, we reverse the rejection of claims 1–5, 12, 15–19, 39, 44, 46–55, and 116 over Public Works, Gall I, Stankowiak I, and Daly. 19 Winter is Hell, Public Works, July 1997, pgs. 53-54. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 32 Claim 50 as obvious over Gall I; Claims 51–53 as obvious over Gall I and Neal;20 claim 54 as obvious over Gall I and Janke Regarding claim 50, the Examiner found that Gall I discloses a deicing composition comprising desugared molasses and a chloride-based deicer or other deicing materials. (RAN 15.) The Examiner found that Gall I does not specifically disclose a composition comprising at least 20% by weight of desugared molasses and 5% to 80% by dry weight calcium chloride or magnesium chloride, but that it would have been obvious to follow the teachings of Gall I to arrive at the claimed composition. (Id.) Patent Owner argues that the obviousness rejection is conclusory and not sufficiently supported. (PO Appeal Br. 10.) Even though the Examiner does not so state in the rejection, Patent Owner also contends that the Examiner improperly relies on the density of desugared beet molasses disclosed in Daly in order to convert the volumetric compositional disclosures in Gall I to the compositions based on weight recited in the claims, because Daly is non-analogous art. (PO Appeal Br. 10–11.) Accordingly, the issue with respect to this rejection is whether the Examiner erred in concluding that the disclosure in Gall I renders claim 50 obvious. We are not persuaded by Patent Owner’s argument that the Examiner did not set forth a sufficient rationale in rejecting claim 50. The Examiner set forth explicit findings as to where in Gall I, the general conditions with respect to the amount and solid content of desugared molasses, as well as the identity and concentrations of the second deicing component are disclosed. 20 US Patent 4,668,416 issued May 26, 1987. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 33 (RAN 15, Gall I, page 3, ll. 7–8, 13–16, 18–19, 21–22, and page 3, l. 30 – page 4, l. 2.) Patent Owner does not dispute that the amounts disclosed in Gall I do not overlap or encompass the amounts recited in claim 50. Patent Owner also does not direct our attention to persuasive evidence that the amounts set forth in claim 50 are critical to the composition. Therefore, we are not persuaded by Patent Owner’s arguments for similar reasons as discussed above with respect to claims 26–35, 38, and 45. Thus, we agree with the Examiner that claim 50 would have been obvious to one of ordinary skill in the art. Patent Owner relies on the same arguments for the rejections of claims 51–54. (PO Appeal Br. 14.) Accordingly, we affirm the Examiner’s rejections of claims 51–54 for the same reasons as claim 50. Claims 64 and 66 as obvious over Gall I, Koefod,21 and Stankowiak I; Claims 65 and 68 as obvious over Gall I, Koefod, Stankowiak I, and Stankowiak II22 Claim 64 recites that the desugared molasses comprises desugared citrus molasses. The Examiner found that Gall I did not specifically disclose a desugared citrus molasses, but found that Koefod discloses deicers having improved corrosion properties including those with molasses solids, where the molasses includes citrus molasses. (RAN 35.) The Examiner acknowledged that Koefod teaches molasses and not desugared molasses, 21 US Patent 6,398,979 B2 issued June 4, 2002. 22 US Patent 5,238,592 issued August 24, 1993. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 34 but determined that it would have been obvious to use desugared citrus molasses because one of ordinary skill in the art would have understood that desugared molasses also contains molasses solids and would have been expected to improve the corrosion resistance of a deicer composition as also taught by Gall I, especially in view of the teaching in Gall I that the desugared molasses is not limited to that from any single source. (RAN 35– 36.) In addition to the arguments addressed above with respect to Gall I, Patent Owner argues that Koefod does not disclose that the molasses solids are present in the deicing composition as a corrosion inhibitor, but rather that the total deicing compound has improved corrosion resistance through the addition of a corrosion inhibitor. (PO Appeal. Br. 16–17.) Furthermore, Patent Owner argues that Koefed does not disclose desugared molasses such that the Examiner’s rationale for combining Koefod with Gall I and Stankowiak I lacks rational underpinnings. (PO Appeal. Br. 17.) Regarding claim 66, similar to Patent Owner’s argument addressed above with respect to claims 73 and 86, Patent Owner contends that the Examiner does not make any reference to the required percentage of sodium formate recited in the claims. (PO Appeal Br. 17–18.) Regarding the rejection of claims 65 and 68, which depend from claim 64, Patent Owner relies on the arguments made for claim 64. (PO App. Br. 18.) We do not agree with Patent Owner that Koefod does not attribute any of the corrosion resistance to the presence of the molasses. Indeed Koefod states expressly that “[e]ven a relatively small dose of molasses can have a Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 35 dramatic improvement in corrosion resistance.” (Col. 4, ll. 1–4; RAN 74.) In addition, the Examiner readily acknowledges the difference between the molasses disclosed in Koefod and desugared molasses in Gall I. We have not been directed to sufficient evidence that the difference between desugared molasses and molasses would have dissuaded one of ordinary skill in the art from looking to the citrus molasses as the source of the desugared molasses as disclosed in Gall I because Gall I expressly is “not limited to de-sugared sugar molasses from any single source.” (Gall I, p. 4, ll. 16–19.) Accordingly, Patent Owner’s arguments are not persuasive. Claim 67 as obvious over Gall I, Koefod, Stankowiak I, and Zaid23 Claim 67 depends from claim 64, and recites that the second deicing component comprises 50% by weight calcium magnesium acetate. The Examiner found that the combination of Gall I, Koefod, and Stankowiak I discloses the deicing composition of claim 67 with the exception of calcium magnesium acetate. (RAN 38.) The Examiner found that Zaid discloses mixed salt deicers including sodium chloride and calcium magnesium acetate, where the use of calcium magnesium acetate is thought to reduce corrosive effects. (RAN 38.) The Examiner concluded that it would have been obvious to have formulated a deicing composition according to Gall I, Koefod, and Stankowiak I having improved corrosion resistance by including the calcium magnesium acetate deicer as taught by Zaid, and that it would have been obvious to have selected the optimum or workable 23 US Patent 5,595,679 issued January 21, 1997. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 36 concentration range of each component including the claimed concentration by routine experimentation. (RAN 38–39.) In addition to the arguments set forth above for claim 64, Patent Owner contends that Zaid fails to disclose the percent by weight of calcium magnesium acetate recited in claim 67. (PO App. Br. 18.) Patent Owner also argues that it would not have been obvious to have combined citrus molasses and calcium magnesium acetate to improve corrosion resistance in the absence of some element that causes corrosion. (Id.) Requester contends that Koefod discloses a 50/50 mixture of molasses/liquid bittern and Gall I discloses that desugared molasses is used with chloride deicing solutions either by itself or mixed with other corrosion inhibitors, such that the combination of Gall I, Koefod, and Zaid discloses the deicing composition recited in claim 67. (Req. Resp’t Br. 13–14.) Patent Owner’s contentions are not persuasive. Stankowiak I, Gall I, and Zaid evince that it was known in the art to add corrosion inhibitors to conventional deicing components that are corrosive but have good deicing properties. Thus, the desugared molasses component and the calcium magnesium acetate component are added as corrosion inhibitors to a conventional deicing component that may have a corrosive effect. Claims 69 and 70 as obvious over Gall I, Koefod, Stankowiak I, Smith,24 and Longworth Claims 69 and 70 depend from claim 64, and further recite that the second deicing component comprises 70% by weight ethylene glycol and 24 US 5,064,551 issued November 12, 1991. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 37 70% by weight diethylene glycol, respectively. Patent Owner contends that the Examiner does not address the proportional percent by weight requirement of the second component recited in claims 69 and 70. (PO Appeal. Br. 18–19.) However, the Examiner found that it would have been obvious to have selected the optimum workable concentration range of each component by routine experimentation. (RAN 39–40.) Patent Owner has not explained why such ranges would not include the percentages by weight recited in the claims, nor has Patent Owner explained how such weight percentages are critical to the invention. Accordingly, we are not persuaded by Patent Owner’s argument. Claims 72, 75, 85, and 88 as obvious over Gall I, Stankowiak I, and Stankowiak II; Claims 74 and 87 as obvious over Gall I, Stankowiak I, and Zaid; Claims 76, 77, 89, and 90 as obvious over Gall I, Stankowiak I, Smith, and Longworth For the claims subject to these rejections, Patent Owner relies on similar arguments already addressed above with respect to the rejection over Gall I and Stankowiak I, and with respect to the claims reciting particular percentages, similar argument as addressed above with respect to claims 73 and 86. (PO Appeal Br. 19–20.) We find Patent Owner’s arguments to be unpersuasive for similar reasons discussed above. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 38 Claim 92 as obvious over Gall I, Murray,25 and Koefod Claim 92 recites a deicing composition comprising at least 20% by weight desugared citrus molasses and a second deicing component comprising 45% by weight calcium chloride. Patent Owner contends that the rejection does not account for the percentage by weight desugared molasses for similar reasons as addressed above with respect to Gall I. (PO Appeal. Br. 20–21.) In addition, Patent Owner relies on similar arguments as addressed above with respect to Koefod. (PO Appeal. Br. 21.) We are not persuaded by Patent Owner’s arguments for similar reasons as expressed above. Claims 78 and 80 as obvious over Gall I, Koefod, and Stankowiak I; Claims 79 and 82 as obvious over Gall I, Stankowiak I, Koefod, and Stankowiak II; Claims 97, 101, and 102 as obvious over Gall I, Neal, and Koefod; Claim 81 as obvious over Gall I, Stankowiak I, Koefod, and Zaid For claims 97 and 101, which recite deicing compositions comprising at least 20% by weight of desugared citrus molasses and a second deicing component comprising 40% by weight magnesium chloride or 42% by weight potassium chloride, respectively, Patent Owner relies on similar arguments above regarding the disclosure of Gall I and Koefod. We are not persuaded for the reasons expressed above with respect to the rejection of claim 50 over Gall I, and the rejection of claims 64 and 66 over Gall I, Koefod, and Stankowiak I. 25 US Patent 5,296,167 issued March 22, 1994. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 39 Regarding claim 80, which recites the presence of 55% by weight sodium formate, we are not persuaded by Patent Owner’s arguments (PO Appeal Br. 23) for the same reasons as discussed above with respect to claims 73 and 86. Regarding claims 78 and 102, which are directed to “desugared sorghum molasses,” Patent Owner contends that Koefod discloses grain molasses but does not disclose desugared grain molasses and that at best Koefod discloses a genus of grain molasses, of which there are at least 20 different types of grains including sorghum. (PO Appeal Br. 21, 23.) Requester contends that the there is evidence of record that shows grain molasses is understood by one of ordinary skill in the art to mean grain sorghum, the sorghum molasses of the claims. (Req. Resp’t Br. 16–17; citing “MOLASSES-GENERAL CONSIDERATIONS,” by Dr. Leo V. Curtin, RAN 6.) We agree with Requester, that in view of the description in the RAN (RAN 6) and the prior art cited therein, one of ordinary skill in the art would have immediately understood sorghum molasses as a grain molasses referred to in Koefod. Further, we have not been directed to sufficient evidence that the difference between desugared molasses and molasses would have dissuaded one of ordinary skill in the art from looking to the sorghum molasses as the source of the desugared molasses as disclosed in Gall I because Gall I expressly is “not limited to de-sugared sugar molasses from any single source.” (Gall I, p. 4, ll. 16–19.) Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 40 For claims 79, 81, and 82, Patent Owner relies on the dependency of these claims from claim 78. (PO Appeal Br. 23–24.) Accordingly, we are not persuaded by Patent Owner’s arguments as discussed above. Claims 83 and 84 as obvious over Gall I, Stankowiak I, Koefod, Smith, and Longworth Claims 83 and 84 depend from claim 78. Patent Owner relies on the arguments made for claim 78, or in the alternative on similar arguments as made for claims 69 and 70. (PO Appeal Br. 24.) We are not persuaded for the reasons addressed above. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 41 Claims 95 and 99 as obvious over Koefod and Gall I Patent Owner relies on similar arguments for these claims as relied upon for claims 64 and 102 addressed above. (PO Appeal Br. 25.) We are not persuaded for the reasons set forth above. Claim 103 as obvious over Gall I, Public Works and Greenwald26 Claim 103 recites a “composition for deicing or inhibiting the formation of ice and snow on surfaces comprising a mixture of desugared sugar cane molasses and rock salt and including 8 gallons of desugared sugar cane molasses per ton of rock salt.” The Examiner found that Gall I discloses desugared cane molasses as a corrosion inhibitor in deicing materials with sodium chloride deicers. (RAN 52.) The Examiner found that Gall I does not disclose that desugared cane molasses is used in an amount of 8 gallons per ton of rock salt. The Examiner found that Greenwald discloses examples of ice melting agents including rock salt (sodium chloride). (RAN 53.) The Examiner found that Public Works discloses use of ICE BAN, a product that can be described as molasses or other base stock with much of the sugar removed, which is used in combination with a salt deicer to reduce the corrosive effect of the salt. (RAN 52.) The Examiner found that Public Works discloses a range for the use of desugared molasses with rock salt from 100/0% (i.e., all desugared molasses and no rock salt) to 32 gallons of desugared molasses per ton of rock salt, and that it would have been obvious to have selected optimal or workable ranges of the desugared cane molasses and rock salt, including the 26 US Patent 4,597,884 issued July 1, 1986. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 42 amount of 8 gallons desugared molasses per ton of rock salt, by routine experimentation. (RAN 53.) Patent Owner contends that the Examiner’s reliance on Public Works is misplaced, because it discloses a fermentation product, which is distinct from the desugared molasses as claimed. (PO Appeal. Br. 22.) Patent Owner contends also that the range of amounts of ICE BAN used in combination with rock salt disclosed by Public Works (32 gal/ton) is greater than the claimed 8 gallons per ton of rock salt, and in particular that the rejection does not accurately assess the teachings of Public Works. (PO Appeal Br. 22.) In particular, Patent Owner argues that Public Works discloses ICE BAN without salt is irrelevant to the combination of ICE BAN with salt, and that the single value of road salt with ICE BAN, which is 400% greater than the claimed value, cannot be relied upon to disclose the required percentage of rock salt. (PO Appeal. Br. 22.) Accordingly, the issue with respect to this rejection is whether the amount of desugared sugar cane molasses per ton of rock salt would have been obvious in view of the prior art of record. We agree with the Examiner that the amount of desugared sugar cane molasses would have been obvious to one of ordinary skill in the art. Initially, we observe that the Examiner does not rely on Public Works for the particular type of desugared molasses disclosed therein. Thus, despite the reference in Public Works to fermentation products disparaged in the ’684 Patent, Public Works provides general information as to the amounts of molasses-based corrosion inhibitors added to deicing materials. Public Works discloses using eight gallons of Ice Ban (DSBM) per ton of a salt Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 43 mix. (Public Works 54.) We acknowledge that the salt mix is 25% salt in that example, however, Public Works also discloses several other examples of using eight gallons of Ice Ban per ton of mix. (Public Works 53-54.) Thus, Public Works does discloses that 8 gallons per ton is a general rule for achieving corrosion inhibiting properties using a desugared molasses. As such, one of ordinary skill in the art would have been directed to similar amounts when formulating similar deicing compositions with molasses based corrosion inhibitors to achieve a corrosion inhibiting effect. In addition, we agree with the Examiner that it is not inventive to determined optimal or workable amounts by routine experimentation, and Patent Owner does not direct our attention to evidence indicating that the particular amount as claimed is critical to achieving a specific result. Aller, 220 F.2d at 456. Accordingly, we affirm the Examiner’s rejection of claim 103. Claims 121 and 122 as obvious over Gall I, Stankowiak II, and Crofoot27 The Examiner found that Gall I discloses the desugared molasses as claimed, which is useful as a corrosion inhibitor in chloride-based deicers or other deicing materials. (RAN 63.) The Examiner found that Gall I fails to disclose the particular salts recited in the claims or that desugared molasses is derived from the Steffen process. (Id.) The Examiner relied on Stankowiak II for the particular salts and Crofoot for teaching a process of 27 US Patent 1,581,179 issued April 20, 1926. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 44 making desugared molasses that is derived from the Steffen process and may be used as the desugared molasses disclosed in Gall I. (RAN 64.) Regarding claim 121, Patent Owner relies on the arguments with respect to the percentages disclosed in Gall I, which we have found unpersuasive as discussed above. (PO Appeal Br. 25.) In addition, Patent Owner argues that the Examiner’s combination lacks the appropriate rational underpinning to support an obviousness rejection because Crofoot discloses using desugared beet molasses as an antifreeze agent, but Gall I discloses desugared beet molasses as a corrosion inhibitor, such that in combination, there would be no second component as claimed. (PO Appeal Br. 25.) We agree with the Examiner with respect to claim 121, because Crofoot is not necessary to reject claim 121. Crofoot is relied upon for production process of desugared molasses, which is not recited in claim 121. However, with respect to claim 122, we agree with Patent Owner that the Examiner’s combination lacks rational underpinnings with respect to Crofoot. That is, as Patent Owner points out, Crofoot discloses desugared molasses as an antifreeze agent for “automobile radiators and for similar purposes.” (Crofoot, ll. 9–11.) Thus, similar to the disclosure in Daly, which discloses using the molasses as a tire ballast because it does not freeze at low temperatures and which the Federal Circuit held was non-analogous art, we have not been directed to sufficient explanation as to how such a disclosure is either in the same field of endeavor as Patent Owner or how an antifreeze composition for use in engines would have been reasonably pertinent to the Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 45 problem with which the inventors of the ’684 Patent were concerned of treating roads with a deicing composition. Accordingly, we affirm the Examiner’s rejection of claim 121. However, we reverse the Examiner’s rejection of claim 122. Summary of Claims Subject to Patent Owner’s Appeal As a result of the above discussion, the claims rejected by the Examiner and affirmed are: claims 1–5, 8–10, 12, 15–19, 22–24, 26–35, 38–47, 49–55, 62, 64–70, 72–90, 92, 95, 97, 99, 101–103, and 121. The Examiner’s decision to reject claims 48, 58, 106–119, 122–125 is reversed. Below we address Requester’s challenges to the non-adoption of certain rejections involving claims 58 and 117–119, which stood rejected on appeal but which now have been reversed. In addition, we address Requester’s challenges to the non-adoption of certain rejections involving claims 56, 57, 59–63, 120, and 126–131, which were not the subject of Patent Owner’s appeal. REQUESTER’S APPEAL A listing of the specific rejections argued by Requester may be found in Requester’s Appeal Brief. (Req. Appeal Br. 19.) As discussed above, we limit our discussion of Requester’s Appeal to rejections of those claims that are not subject to rejections that have been affirmed as discussed above with Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 46 respect to Patent Owner’s Appeal. See Tempo Lighting, Inc. v. Tivoli, LLC, 742 F.3d 973, 979 (Fed. Cir. 2014.) Claims 56–58, 60, and 61 as anticipated by Zdzislaw28 Claims 56–58, 60, and 61 depend from claims 1, 15, 46, 26, and 54, which independent claims recite a deicing composition comprising desugared molasses and a second deicing component. Requester does not argue any particular limitations of claims 56–58, 60, and 61, which recite particular second deicing components, but rather contends that the Examiner erred by not adopting the rejection of claims 1, 15, 46, 26, and 54, because the Examiner erred in determining that Zdzislaw fails to disclose a desugared molasses. (Req. Appeal Br. 22–23; RAN 27.) The Examiner’s reasoning for not adopting the rejection is consistent with the reasoning of the Federal Circuit, which held that the molasses disclosed in Zdzislaw, which “contains approximately 50% of sugar” is not the desugared beet molasses disclosed in the ’330 Patent. Natural Alternatives, 659 Fed.Appx. at 612–13. Accordingly, we affirm the Examiner’s decision not to adopt the proposed rejection. Requester argues that “the molasses of Zdzislaw comes from the same process and performs the same function as the desugared molasses of the ’684 patent; therefore, it would be obvious to use in place of the desugared molasses of the '684 patent.” (Req. Appeal Br. 23–24.) In view of the above discussion of the molasses disclosed in Zdzislaw, Requester’s position is not persuasive. 28 PL 164018 B1, published Nov. 7, 1990. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 47 Claim 59 as obvious over Zdzislaw and Gall I Claim 59 depends from claim 50, and further recites specific second deicing components. Requester points out that claim 50 stands rejected over Gall I alone, and argues that it would have been obvious “to substitute the desugared molasses of Zdzislaw for the desugared molasses of Gall I patent since both are a waste or byproduct of sugar beet production, and both are use in anti-icing/de-icing compositions.” (Req. Appeal Br. 24.) Requester refers to Comments submitted on September 16, 2011 (THIRD-PARTY REQUESTER’S COMMENTS ON ACTION CLOSING PROSECUTION AND PATENT OWNER’S COMMENTS filed September 16, 2011, “September 2011 Comments”) for the proposed rejection. (Id.) In the September 2011 Comments, Requester contends that Zdzislaw discloses a combination of desugared molasses and ethylene glycol, but Zdzislaw does not disclose the solids range recited in the claims. (September 2011 Comments 34–35.) Requester contends that it would have been obvious to use the desugared molasses of Gall I for the desugared molasses of Zdzislaw combined with ethylene glycol, because Zdzislaw and Gall I both disclose a desugared molasses from sugar beets, and as such it would just be a simple substitution of one element for another. (September 2011 Comments 35.) The Examiner did not adopt the rejection because the Examiner found that Zdzislaw does not disclose desugared molasses and Gall I does not provide a reason to substitute desugared molasses in a composition as taught by Zdzislaw. (RAN 27–28.) We agree with the Examiner. As discussed above, the Federal Circuit held that Zdzislaw does not disclose “desugared molasses.” As a result, Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 48 Requester’s rationale, which is based on the premise that Zdzislaw discloses desugared molasses does not rest on sufficient rational underpinnings. Claims 62 and 63 as obvious over Public Works Claim 62 recites a deicing composition comprising greater than 25% by weight desugared molasses and a second deicing component selected from the group consisting of the sodium, calcium, magnesium, and potassium salts of chloride. Claim 63 recites that the second deicing component is sodium chloride. The Examiner did not adopt the rejection because “the teachings of Public Works do not encompass the subject matter (i.e., desugared molasses concentration) of claims 62 and 63.” (RAN 28–29.) Requester contends that the Examiner erred in not adopting the rejection of claims 62 and 63 over Public Works because Public Works discloses the general conditions of the claims, a combination of desugared molasses and road salt, such that the determination of the exact amounts required in the claim would have been obvious to one of ordinary skill in the art. (Req. Appeal Br. 25–26.) The Federal Circuit held that Public Works discloses “fermentation and distillation” desugared molasses product, which is a different product then the desugared molasses disclosed in the ’684 Patent. Natural Alternatives, 659 Fed.Appx. at 615. Thus, Public Works does not disclose a desugared molasses as recited in the claims. Accordingly, we affirm the Examiner’s decision not to adopt the proposed rejection. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 49 Claims 119 and 120 as obvious over Gall I, Stankowiak II, and Crofoot Requester argues that Gall I discloses a corrosion inhibited deicing compound including desugared molasses and chloride salt, but does not recite a specific concentration of 70% by weight for desugared molasses and 30% for the second deicing component. (Req. Appeal Br. 33.) Requester contends that the differences in concentrations between Gall I (1–50% desugared molasses) and claim 119 would have been obvious, because it is not inventive to discover the optimum or workable ranges by routine experimentation as further evidenced by statements in the ’684 Patent (col. 6, ll. 47–51) suggesting that the exact amounts are not critical. (Req. Appeal Br. 33–34.) Requester relies on Stankowiak II for the disclosure of magnesium chloride recited in claim 120. (Req. Appeal Br. 34–35.) Here, we observe that Requester does not appear to rely on Crofoot for the rejection of claims 119 and 120. Indeed, as originally proposed it appears that Crofoot was included by Requester for the limitations of claim 122, which we addressed above. (See “THIRD PART[Y] REQUESTER’S RESPONSE TO PATENT OWNER’S AMENDMENT AND RESPONSE” filed November 13, 2014.) The Examiner stated: “Because the cited prior art does not teach a method of deicing an icy surface with a deicing composition comprising 70% by weight of desugared molasses having 60% to 65% suspended solids, the proposed rejection of claims 119 and 120 is not adopted.” (RAN 62.) Patent Owner contends that the ’684 Patent discloses particular results created by amounts of the deicing composition as claimed. (PO Resp’t Br. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 50 12, Patent Owner cite incomplete.) Patent Owner argues that contrary to Requester’s position that it is cost effective to ship aqueous compositions in a concentrated form, it would be more expensive to ship concentrated desugared molasses, because it would require the user to procure more desugared molasses. (Id.) We agree with Requester. The Examiner’s reasoning for not adopting the rejection does not adequately explain why varying the amounts of Gall I would not have been obvious. Contrary to Patent Owner’s position, the ’684 Patent’s general reference to “very good results” obtained with the amount of desugared beet molasses does not attribute the results obtained to the particular amounts of desugared molasses chosen. (’684 Patent, col. 7, ll. 34–54.) In this regard, the ’684 Patent discloses that the compositions may be applied in any amount effective for its intended purpose and may be determined by one of ordinary skill in the art. (’684 Patent col. 6, ll. 47–55.) In other words, as discussed above, it is not inventive to determined optimal or workable amounts by routine experimentation, and Patent Owner has not shown that the particular amounts recited in claim 119 are critical to obtaining unexpectedly beneficial results. Aller, 220 F.2d at 456. Accordingly, we reverse the Examiner’s decision not to reject claims 119 and 120 over the combination of Gall I and Stankowiak II. Therefore, pursuant to 37 C.F.R. § 41.77(b), we enter a new ground of rejection of claims 119 and 120 only as obvious over the combination of Gall I and Stankowiak II. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 51 Claims 126–128 as obvious over Zdzislaw, Stankowiak II, Crofoot, and Blake; Claims 129–131 as obvious over Zdzislaw, Stankowiak II, Crofoot, and Blake For both of these rejections, Requester contends, inter alia, that “it would be obvious to substitute the desugared molasses of Zdzislaw with the desugared molasses from Crofoot, since Crofoot discloses that a Steffen process is used to manufacture desugared sugar beet molasses.” (Req. Appeal Br. 36, 38.) The Examiner did not adopt these rejections because Zdzislaw does not disclose a desugared molasses. (RAN 64.) Patent Owner agrees because Requester’s reasoning lacks a rational underpinning as it is based on Zdzislaw disclosing desugared molasses, where Zdzislaw discloses molasses. (PO Resp’t Brief 13.) We agree with the Examiner. That is, the rationale proposed by Requester relies on the proposition that Zdzislaw discloses desugared molasses. However, as held by the Federal Circuit, Zdzislaw does not disclose desugared molasses, but rather discloses “making molasses in the traditional sugared form.” Natural Alternatives, 659 Fed.Appx. at 613. Accordingly, we affirm the Examiner’s decision not to adopt the proposed rejections. DECISION The Examiner’s decision to reject claims 1–5, 8–10, 12, 15–19, 22– 24, 26–35, 38–47, 49–55, 62, 64–70, 72–90, 92, 95, 97, 99, 101–103, and 121 is affirmed. Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 52 The Examiner’s decision to reject claims 40–42 under 35 U.S.C. § 314; claims 40–42 under 35 U.S.C. § 112, fourth paragraph; and claims 39, 44–47, 58, and 119, first paragraph are reversed. In addition, the Examiner’s decision to reject claims 48, 106–118, 122–125 over the prior art is reversed. The Examiner’s decision not to reject claims 56–63 and 126–131 is affirmed. However the Examiner’s decision not to reject claims 119 and 120 is reversed and a new ground of rejection is entered only for claims 119 and 120. TIME PERIOD FOR RESPONSE This decision contains new grounds of rejection pursuant to 37 C.F.R. § 41.77(b) which provides that “[a]ny decision which includes a new ground of rejection pursuant to this paragraph shall not be considered final for judicial review.” Correspondingly, no portion of the decision is final for purposes of judicial review. A requester may also request rehearing under 37 C.F.R. § 41.79, if appropriate, however, the Board may elect to defer issuing any decision on such request for rehearing until such time that a final decision on appeal has been issued by the Board. For further guidance on new grounds of rejection, see 37 C.F.R. § 41.77(b)–(g). The decision may become final after it has returned to the Board. 37 C.F.R. § 41.77(f). Section 41.77(b) of Title 37 of the Code of Federal Regulations also provides that the Owner, WITHIN ONE MONTH FROM THE DATE OF THE DECISION, must exercise one of the following two options with Appeal 2017–011228 Reexamination Control 95/001,136 Patent 6,416,684 B1 53 respect to the new grounds of rejection to avoid termination of the appeal as to the rejected claims: (1) Reopen prosecution. The owner may file a response requesting reopening of prosecution before the examiner. Such a response must be either an amendment of the claims so rejected or new evidence relating to the claims so rejected, or both. (2) Request rehearing. The owner may request that the proceeding be reheard under § 41.79 by the Board upon the same record . . . . Any request to reopen prosecution before the examiner under 37 C.F.R. § 41.77(b)(1) shall be limited in scope to the “claims so rejected.” Accordingly, a request to reopen prosecution is limited to issues raised by the new ground(s) of rejection entered by the Board. A request to reopen prosecution that includes issues other than those raised by the new ground(s) is unlikely to be granted.
