O’LEARY Appeal 2017-000170 Application 12/875,6401 Technology Center 1700 Before ROMULO H. DELMENDO, KAREN M. HASTINGS, and JAMES C. HOUSEL, Administrative Patent Judges. PER CURIAM. DECISION ON APPEAL 1 The Applicant (hereinafter “Appellant”) states that the real party in interest is “OCV Intellectual Capital, LLC.” Appeal Brief filed on October 26, 2015, hereinafter “Appeal Br.,” 3. Appeal 2017-000170 Application 12/875,640 The Appellant appeals under 35 U.S.C. § 134(a) from the Primary Examiner’s final decision to reject claims 44—66.2,3 We have jurisdiction under 35 U.S.C. § 6(b). We affirm. A. BACKGROUND The subject matter on appeal relates to spray foam compositions used to fill cavities, cracks, and crevices to enhance the sealing and insulating properties of buildings. Specification, hereinafter “Spec.,” 12. According to the Appellant, the spray foam compositions (formulated as two-part spray foams) are non-toxic, environmentally friendly, and capable of being applied at low temperatures. Id. ^ 18. Representative claim 44 is reproduced from page 26 of the Appeal Brief (Claims Appendix), as follows (emphases added): 44. A two-part non-aqueous foamable composition for forming a foam comprising: 2 Appeal Br. 13—25; Reply Brief filed on September 28, 2016, hereinafter “Reply Br.,” 2—6; Examiner’s Answer (notice emailed on July 29, 2016), hereinafter “Ans.,” 2—21; Final Office Action (notice emailed on January 26, 2015) hereinafter “Final Act.,” 3—24. 3 The Appellant states there are no related appeals, interferences, or trials at page 4 of the Appeal Brief. However, Appeal 2016-008635 (Application No. 12/688,951) and Appeal 2017-003603 (Application No. 13/113,785) appear to be related to this application. See 37 C.F.R. § 41.37(c)(ii). This application is a continuation-in-part of the application involved in Appeal 2016-008635. In addition, the application involved in Appeal 2016-008635 claims priority to a common provisional application as the application involved in Appeal 2017-003603. The Appeal Brief for Appeal 2016- 008635 was filed on April 23, 2015, and the Appeal Brief for Appeal 2017- 003603 was filed on September 11, 2015. These filings occurred before the Appeal Brief for this appeal was filed. 2 Appeal 2017-000170 Application 12/875,640 a first part including: a lattice phase comprising a dry polymer present in an amount of 40-70% by weight', a liquid blowing agent present in an amount of 25— 50% by weight', a multifunctional acid present in an amount of 2— 10% by weight', and a surfactant; and a second part including: a polyfunctional aziridine present in an amount of 10—25% by weight', a plasticizer having no acidic protons to react with the polyfimctional aziridine; wherein the first part and the second part are separated until formation of the foam; wherein the first part and the second part are substantially free of isocyanate; and wherein the composition forms a foam when the first part and the second part are combined at a temperature below room temperature. B. REJECTIONS ON APPEAL On appeal, the Examiner maintains several rejections, which are as follows (Ans. 2—21; Final Act. 3—24): I. claims 44—66 under pre-AIA 35 U.S.C. § 112, second paragraph, as being indefinite; II. claims 44, 54, 63, 65 under pre-AIA 35 U.S.C. § 112, first paragraph, as failing to comply with the written description requirement; III. claims 44—66 under pre-AIA 35 U.S.C. § 103(a) as being unpatentable over Osipow et al. (Osipow)4 in view of 4 US 4,328,329, issued May 4, 1982. 3 Appeal 2017-000170 Application 12/875,640 Gosiewski et al.5 (Gosiewski), Koshy,6 Yeo,7 and Travis,8 as evidenced by Wikipedia;9 IV. claims 44—66 as being unpatentable under pre-AIA 35 U.S.C. § 103(a) over Osipow in view of Gosiewski, Koshy, Yeo, and Kho et al.10 (Kho), as evidenced by Wikipedia; and V. provisionally, claims 44—66 on the judicially-created doctrine of obviousness-type double patenting as being unpatentable over claims 1, 2, 4, 8, 9, and 21—28 of copending application 12/688,951 in view of Osipow and Gosiewski. C. DISCUSSION Rejection I Claims 44—66 are rejected under 35 U.S.C. § 112, second paragraph, as being indefinite. The Examiner finds independent claims 44 and 54 do not specify a basis for the weight percentages of the dry polymer, the liquid blowing 5 US 5,945,461 A, issued Aug. 31, 1999. 6 US 6,451,876 Bl, issued Sept. 17, 2002. 7 US 6,537,934 Bl, issued Mar. 25, 2003. 8 US 3,874,914, issued Apr. 1, 1975. 9 Wikipedia entry for “Room temperature,” http://www.en.wikipedia.org/wiki/Room_temperature (first publication date unknown). The Appellant does not contest the prior art status of this publication. See, e.g., Appeal Br. 20. 10 WO 2008/088116 Al, published July 24, 2008. 4 Appeal 2017-000170 Application 12/875,640 agent, the multifunctional acid, or the polyfunctional aziridine. Ans. 3. In particular, the Examiner observes that “the weight percentages may be interpreted as being based on either o[f] the first and second parts, or based on the total composition” and that the weight percentages for these components may vary depending on the basis selected. Id. at 3^4. As a result, the Examiner concludes the scope of the claims is indefinite. Id. at 4. The Appellant contends the weight percentages recited in claims 44 and 54 are definite in view of Appellant’s Specification, which discloses a weight percentage basis for each of the dry polymer, the liquid blowing agent, the multifunctional acid, and the polyfunctional aziridine. Appeal Br. 15-17; Reply Br. 5-6. The Appellant’s arguments are not persuasive. We agree with the Examiner’s finding that claims 44 and 54 do not specify a basis for the weight percentages of the dry polymer, the liquid blowing agent, the multifunctional acid, or the polyfimctional aziridine. Claims 44 and 54 merely recite “by weight” for each of these components without reciting whether the weight percentage is based upon the weight of the first part, the second part, or the total weight of the composition or the resulting foam. Appeal Br. 26. As argued by the Appellant, the Specification discloses different bases for the weight percentages of the dry polymer, the liquid blowing agent, the multifunctional acid, and the polyfunctional aziridine. Specifically, the weight percentage basis for the dry polymer is the weight of the first part, the weight percentage basis for the blowing agent is the weight of the first part, the weight percentage basis for the multifunctional acid is the weight of the dry foam composition, and the weight percentage basis for the 5 Appeal 2017-000170 Application 12/875,640 polyfunctional acid is the weight of the dry foam composition. Spec, 37— 39, 42. But these disclosures, which describe non-limiting embodiments, do not inform one skilled in the relevant art that the bases selected for the components should remain constant throughout the Specification (e.g., by using definitive language such as “By ‘% by weight,” we mean . . . .”). In re ICON Health & Fitness, Inc., 496 F.3d 1374, 1379 (Fed. Cir. 2007) (“[W]e look to the specification to see if it provides a definition for claim terms, but otherwise apply a broad interpretation.”). Therefore, we decline to interpret claims 44 and 54 as including the varying weight percentage bases disclosed in the Specification. Such an interpretation would not be under the broadest reasonable interpretation of the claims read in light of the Specification but instead would impermissibly import features from the Specification into the claims. Although claims are to be interpreted in light of the specification, limitations from the specification are not to be read into the claims. See In re Van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993). For these reasons and those discussed in the Examiner’s Answer, we uphold the Examiner’s rejection of claims 44—66 as being indefinite. The Examiner further finds independent claims 44 and 54 are indefinite because the language “below room temperature” is not clearly defined in Appellant’s Specification. Ans. 5. The Appellant does not submit any arguments in response to this rejection. Appeal Br. 14—25. Therefore, we summarily affirm the Examiner’s rejection of claims 44—66 on the basis that the language “below room temperature” is indefinite. 6 Appeal 2017-000170 Application 12/875,640 Rejection II Claims 44, 54, 63, 65 are rejected under 35 U.S.C. § 112, first paragraph, as failing to comply with the written description requirement. The Examiner finds independent claims 44 and 54 do not specify the basis for the recited weight percentage ranges. Ans. 5. Therefore, the weight percentages encompass various weight percentages bases (e.g., based upon the weight of the first part or the second part or based upon the total weight of the composition or resultant foam). The Examiner finds the Appellant’s Specification provides support for a specific weight percentage basis for each of the dry polymer, blowing agent, multifunctional acid, and the polyfunctional aziridine, but this provides a more narrow range of percentages than what is encompassed by the claims. Id. at 5—6. The Examiner further finds dependent claims 63 and 65 have a similar issue because claims 63 and 65 recite “by weight” but no basis for the weight percentage. Id. at 6. The Appellant asserts the Specification discloses only one basis for each of the weight percentages recited in claims 44 and 54, and, in view of this, the Appellant had possession of the claimed invention under § 112 at the time the application was filed. Appeal Br. 17—18; Reply Br. 5—6. The Appellant’s argument is unpersuasive. Claims 44 and 54 were submitted as new claims on September 17, 2013 (i.e., after the application was filed). As discussed above, we do not interpret claims 44 and 54 as requiring the weight percentage bases disclosed in non-limiting embodiments described in the Specification. As a result, claims 44 and 54 are broader and encompass weight percentage bases other than those disclosed in the Specification. Because claims 63 and 65 respectively 7 Appeal 2017-000170 Application 12/875,640 depend from claims 44 and 54, claims 63 and 65 suffer from the same deficiency, which is not remedied by the additional recitations of claims 63 and 65. Therefore, for these reasons and those discussed in the Examiner’s Answer, we uphold the Examiner’s rejection under § 112, first paragraph, for lack of written description support for the claimed weight percentages. Additionally, the Examiner finds the Specification does not provide support for the first and second parts forming a foam when they are combined “at a temperature below room temperature,” as recited in claims 44 and 54. Ans. 6. In particular, the Examiner finds the Specification discloses a foam that is suitable for use at low temperatures, such as temperatures below freezing, but does not disclose combining the first and second parts to form a foam at a temperature “below room temperature.” Id. at 6—7 (citing Spec. H 33, 48). The Examiner also finds the Specification discloses heating a spray gun above the boiling point of a blowing agent, which supplies heat to the mixture of the first and second parts, and the Specification discloses the use of blowing agents having boiling points above room temperature (i.e., above 25 °C). Id. at 7, 25 (citing Spec. Tflf 38, 49). The Appellant argues the Specification’s disclosure of using a heated gun to heat foam composition components to a temperature above the boiling point of a blowing agent does not necessarily mean the mixture of foam composition components is heated above room temperature and one of ordinary skill in the art would understand “that many blowing agents have boiling points that are below room temperature.” Appeal Br. 18—19. The Appellant also cites the Specification’s disclosure that the two-part spray foams are suitable for use below freezing. Id. at 19. 8 Appeal 2017-000170 Application 12/875,640 These arguments do not identify a reversible error in the Examiner’s rejection. The Specification contemplates forming a foam at a temperature above room temperature by disclosing the use of a spray gun that “is heated to a temperature above the boiling point of the blowing agent”11 and the Examiner finds it discloses the use of blowing agents having boiling points above room temperature (i.e., above 25 °C).12 The Appellant does not refute the Examiner’s finding for the latter. But the Specification does not provide explicit support for combining the first and second parts to form a foam “at a temperature below room temperature.” Nor does the Specification provide implicit support. The Specification discloses a spray foam sealant “that may be applied in cold temperatures, particularly at temperatures approaching about 20 °F” and a “foam that is suitable for use at low temperatures (e.g., temperatures below freezing)” but the range recited in the claim encompass other temperatures above and beyond those described. Spec. 5, 19, 33. In re Wertheim, 541 F.2d 257, 263—264 (CCPA 1976) (“By pointing to the fact that claim 1 reads on embodiments outside the scope of the description, the PTO has satisfied its burden [of establishing lack of written description]”). Therefore, the Specification does not reasonably convey to those skilled in the art that the Appellant had possession of a foam composition that forms a foam at a temperature in the range of “below room 11 Spec. 149. 12 The Specification discloses use of a cross linking agent that crosslinks at room temperature and that a resultant foam “should be fluid enough to be sprayed either at room temperature or by heating.” Spec. H 21, 36. These disclosures do not provide support for combining first and second parts of a composition to form a foam at a temperature below room temperature, as recited in claims 44 and 54. 9 Appeal 2017-000170 Application 12/875,640 temperature,” as recited in claims 44 and 54. For these reasons and those discussed in the Examiner’s Answer, we uphold the Examiner’s rejection under § 112, first paragraph, for lack of written description support for the language “at a temperature below room temperature.” Rejection III Claims 44—66 are rejected as being unpatentable under 35 U.S.C. § 103(a) over Osipow in view of Gosiewski, Koshy, Yeo, and Travis, as evidenced by Wikipedia. Because the claims are argued together, we select claim 44 as representative of the issues discussed below. The Examiner finds Osipow discloses a composition including a synthetic polymer (e.g., polyvinyl acetate, carboxylated vinyl acetates, acrylates, and vinyl toluene-butadiene copolymers), a liquid propellant, a surfactant, a plasticizer, and a curing agent (i.e., a cross linking agent), wherein the composition, when withdrawn from a container, forms a foam when the propellant rapidly volatilizes. Ans. 7—8. The Examiner finds the composition is free of isocyanates and is a non-aqueous composition but is not a two-part composition in which the polymer, liquid propellant, and surfactant are included in a first part and the plasticizer and curing agent are in a second part, with the first part further including a multifunctional acid and the curing agent is polyfunctional aziridine, as recited in claim 44. Id. at 8-9. The Examiner finds Gosiewski discloses a two-part composition comprising a first part including a polymer composition, a foaming agent, and an acid (e.g., lactic acid), and a second part including a plasticizer. Id. at 10 Appeal 2017-000170 Application 12/875,640 9. The Examiner finds Gosiewski discloses the use of a curing agent as an additional component. Id. The Examiner further finds Gosiewski discloses mixing the two-part composition at 72°F, which the Examiner finds to be below room temperature. Id. at 9—10 (citing the Wikipedia entry for “Room temperature”). Alternatively, the Examiner finds the temperature disclosed by Gosiewski is close to below room temperature such that one of ordinary skill in the art would have expected the resultant foam of Gosiewski and one formed below room temperature to have the same properties. Id. at 10. The Examiner cites Koshy as an additional disclosure of a two-part foam composition in which a first part includes a resin, a rubber, a filler, and a blowing agent and a second part includes a curative system, with mixture of the two parts resulting in curing and foaming of the composition in a remarkably controlled fashion. Id. Based on this disclosure and Gosiewski’s, the Examiner concludes it would have been obvious to modify the composition of Osipow so it is separated into two parts, with the first part including the polymer, the acid, the blowing agent, and surfactant and the second part including the curing agent, plasticizer, and filler so premature reaction of the components is prevented. Id. at 10—11. The Appellant contends the Examiner has failed to establish a reason to modify Osipow in view of Gosiewski and has engaged in impermissible hindsight. Appeal Br. 20—22; Reply Br. 2-A. Specifically, the Appellant argues there would have been no reason to modify Osipow’s composition to become a two-part composition because this “would likely increase both complexity and cost to change from a one-part to a two-part composition.” Appeal Br. 22. 11 Appeal 2017-000170 Application 12/875,640 The Appellant’s argument based on increased complexity and cost is unpersuasive because the Appellant provides no evidence or technical reasoning to support it. Moreover, the Examiner provides a rationale for modifying the composition of Osipow that is supported by the disclosures of Gosiewski and Koshy. Gosiewski discloses that a foam composition can be prepared by providing a first part and a second part so the two parts may be mixed together to cause polymerization and foaming just prior to use. Gosiewski 10:33—41. Similarly, Koshy discloses a foam composition in which a first part includes a polymer, a blowing agent, and other constituents and a second part includes a curative system and other components. Koshy 2:43—62. Koshy discloses that combining the two separate parts causes curing and expansion (i.e., foaming) to proceed in a remarkably controlled fashion. Id. at 2:62 to 3:1. The Appellant further argues13 the Examiner has not provided support for the finding that the composition of Osipow is free of isocyanates. Appeal Br. 23—24. The Appellant contends the composition of Osipow would include isocyanates because Osipow discloses “urethane prepolymers” as being suitable for use in its composition. Id. at 24. This argument is also unpersuasive. Osipow discloses various polymers can be used in its composition, such as polyvinyl acetate or carboxylated vinyl acetate, besides urethane prepolymers. Osipow 8:42— 13 At page 4 of the Reply Brief, the Appellant argues against the Examiner’s additional rationale of optimization via routine experimentation as basis for providing a composition having the various component amounts recited in claims 44 and 54. Because this argument is new and the Appellant does not provide a showing of good cause for the delay in presenting the argument, we need not consider it. 37 C.F.R. § 41.41(b)(2). 12 Appeal 2017-000170 Application 12/875,640 9:11. Thus, the disclosure of Osipow supports the Examiner’s findings and is not limited to a urethane prepolymer. With regard to the particular curing agent recited in claim 44, the Examiner finds Osipow, as modified by Gosiewski and Koshy, does not disclose the use of a polyfimctional aziridine. Ans. 11. The Examiner finds Yeo discloses the use of polyfimctional aziridine as a cross linking agent for acrylic and vinyl acetate-based adhesive compositions. Id. The Examiner also finds Travis discloses an adhesive composition in which polyfimctional aziridine is used to improve the adhesion to a substrate. Id. at 11—12. The Examiner concludes it would have been obvious to modify Osipow, as modified by Gosiewski and Koshy, to use polyfimctional aziridine as a cross linking agent to provide excellent adhesive properties and because it would have involved the substitution of one equivalent for another. Id. at 12—13. The Appellant argues the Examiner’s rationale for substituting aziridine for the curing agent of Osipow, as modified by Gosiewski and Koshy, is insufficient because the Examiner has failed to establish that the art has recognized aziridine and the curing agent of Osipow as equivalents. Appeal Br. 22; Reply Br. 6. To support this argument, the Appellant asserts Gosiewski discloses a particular curing agent that is responsible for the properties desired in its foam and this curing agent is a catalyst, which one of ordinary skill in the art would have recognized to be different from aziridine in bonding, structure, and expected mode of reactivity. Appeal Br. 22-23. These arguments do not identify a reversible error in the Examiner’s rejection. As noted above, Osipow discloses various polymers can be used in its composition, such as polyvinyl acetate and carboxylated vinyl acetate. 13 Appeal 2017-000170 Application 12/875,640 Osipow 8:42—9:6. Osipow further discloses its composition can include a curing agent (i.e., cross linking agent) for its polymer. Id. at 10:21—27. Yeo discloses polyfimctional aziridine is a crosslinker that “is reactive with carboxy and hydroxyl groups.” Yeo 2:10-15. Therefore, the polyfimctional aziridine of Yeo would have been reasonably expected to be suitable for use as a cross linking agent with at least the carboxylated vinyl acetate of Osipow, which includes carboxy groups, and is functionally equivalent to the curing agent (i.e., cross linking agent) disclosed by Osipow for use with its polymers. Moreover, Travis discloses polyfimctional aziridine is useful for promoting adhesion to a substrate. Travis 4:67—5:3. Therefore, the disclosures of the applied references support the Examiner’s findings and provide reasons to modify Osipow, as modified by Gosiewski and Koshy, to use polyfimctional aziridine as the curing agent for Osipow’s polymer. Moreover, the Appellant’s arguments regarding the catalyst of Gosiewski do not direct us to a reversible error because the Examiner relies on Osipow as disclosing a curing agent. Ans. 8. In addition, the catalyst of Gosiewski functions as a polymerization catalyst that triggers polymerization of its monomers so the composition will polymerize when it foams. Gosiewski 2:43^48; 5:19-23. The disclosure of Gosiewski demonstrates the difference between the catalyst and a cross linking agent by disclosing a curing agent (i.e., cross linking agent) may be used in addition to the other components of its foam composition, including the polymerization catalyst. Id. at 9:61—64. The Appellant does not argue claims 45—66 separately from claim 44. Appeal Br. 20-24. For these reasons and those discussed in the Examiner’s Answer, we 14 Appeal 2017-000170 Application 12/875,640 uphold the Examiner’s § 103(a) rejection of claims 44—66. Rejection IV Claims 44—66 are rejected as being unpatentable under 35 U.S.C. § 103(a) over Osipow in view of Gosiewski, Koshy, Yeo, and Kho, as evidenced by Wikipedia. In the rejection of claims 44—66, the Examiner makes findings and conclusions similar to those set forth in the rejection over Osipow in view of Gosiewski, Koshy, Yeo, and Travis, as evidenced by Wikipedia, except the Examiner relies upon Kho instead of Travis for an additional disclosure aziridine as a cross linking agent. Ans. 15—21. The Appellant cites the arguments set forth above for Rejection IV and further argues the Examiner has failed to provide a reason for modifying Osipow in view of Gosiewski, Koshy, or Yeo. These arguments are unpersuasive for the same reasons set forth above for Rejection IV. Therefore, we uphold the Examiner’s § 103(a) rejection of claims 44—66 for these reasons and those discussed in the Examiner’s Answer. Rejection V Claims 44—66 are provisionally rejected on the ground of non- statutory obviousness-type double patenting as being unpatentable over claims 1, 2, 4, 8, 9, and 21—28 of copending application 12/688,951 in view of Osipow and Gosiewski. Appellant requests that the rejection be held in abeyance. Appeal Br. 24. Appellant further states a terminal disclaimer has been submitted. Id. at 24—25. We agree with the Examiner’s finding that no terminal disclaimer 15 Appeal 2017-000170 Application 12/875,640 has been filed. Ans. 34. We therefore summarily affirm the Examiner’s provisional non-statutory obviousness-type double patenting rejection of claims 44—66. D. SUMMARY Rejections I—V are affirmed. Therefore, the Examiner’s final decision to reject claims 44—66 is affirmed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l)(iv). AFFIRMED 16 Copy with citationCopy as parenthetical citation
