NAGUMO, Administrative Patent Judge. DECISION ON APPEAL Appeal 2011-002550 Application 10/613,409 2 A. Introduction1 David J. Good, Justin A. Mehaffy, Dale L. Haner, Jagruti B. Patel, Brian D. Morrison, and Fidelin N. Willybiro (“Good”) timely appeal under 35 U.S.C. § 134(a) from the final rejection2 of claims 1-8, 10, 12, 13, 22, and 25-29, which are all of the pending claims. We have jurisdiction. 35 U.S.C. § 6. We AFFIRM. The subject matter on appeal relates to a hot melt adhesive that has an application temperature of less than 250°F (121° C), rather than the conventional application temperature of about 350°F (177° C). (Spec. 1, 3d para.) According to the 409 Specification, the term “application temperature means the temperature to nearest 25°F increment, that the adhesive viscosity falls between about 800cps and 1500cps.” (Id. at 8, 2d full para.) The practical significance of these values is explained by the disclosure that “[t]ypical viscosities for case and carton sealing is desirable [sic] less than 2,000 centipoise (cps) and the majority of commercially employed hot melt application equipment favors a viscosity of below about 1,500 cps.” (Id.) The relatively low application temperature is said to reduce the danger of burns and the exposure to volatile fumes, and to lower the costs of manufacture and use. (Id. at 1, 3d para.) The lower application 1 Application 10/613,409, Hot Melt Adhesive, filed 3 July 2003. The specification is referred to as the “409 Specification,” and is cited as “Spec.” The real party in interest is listed as Henkel Corporation, successor in interest to National Starch and Chemical Investment Holding Corporation. (Appeal Brief, filed 4 June 2010 (“Br.”), 1 [pages not numbered in original.]) 2 Office action mailed 5 January 2010 (“Final Rejection”). Appeal 2011-002550 Application 10/613,409 3 temperatures are also said to enable efficient and expeditious inline mixing methods not previously feasible. (Id. at 3, 2d para.) Moreover, the inventive hot melt adhesives have a bonded adhesive heat stress value3 that is within 100°F of the application temperature. As a result, the disclosed compositions are said to provide superior strength compared to prior art low temperature hot melt adhesives. (Id. at 4, 4th para. through 5, l. 2.) Representative claim 1 reads: 1. A low application temperature hot melt adhesive having a viscosity between about 800 cps and 1500 cps at an adhesive application temperature below 250°F, and wherein the bonded adhesive heat stress value and the adhesive application temperature are separated by 100°F or less. (Br., Claims App. 1 (unnumbered; indentation and paragraphing added.) The Examiner maintains the following grounds of rejection:4 A. Claims 1-5, 8, 10, 12, 13, 22, and 25-29 stand rejected under 35 U.S.C. § 103(a) in view of the teachings of Mehaffy.5 3 The heat stress value is “the temperature at which a stressed bond fails.” (Id. at 5, last para., through 6, 2d full para.) It may be measured by determining whether the adhesive remains intact under a specified load for a specified time at successively higher temperatures. 4 Examiner’s Answer, mailed 18 August 2010 (“Ans.”). 5 Justin A. Mehaffy and Ingrid Cole, Low Application Temperature Hot Melt Adhesive, EP 0 934 990 A1 (1999) (assigned to National Starch and Chemical Investment Holding Corporation, the predecessor to the present real party in interest). Appeal 2011-002550 Application 10/613,409 4 B. Claims 6 and 7 stand rejected under 35 U.S.C. § 103(a) in view of the combined teachings of Mehaffy and Baetzold.6 B. Discussion Findings of fact throughout this Opinion are supported by a preponderance of the evidence of record. Initially, we find that Good has not expressly argued the separate patentability of any claim. Accordingly, all claims stand or fall with claim 1. 37 C.F.R. § 41.37(c)(vii) (2007). Good argues that the Examiner erred in making the “assertion that if the adhesives reported in Table I [of Mehaffy] were applied at 200°F, the resultant difference between the application temperature and the heat stress would be less than 100°F.” (Br. 3, § 7.1, 3d para.) Good proceeds to demonstrate7 that application of the Arrhenius equation describing the temperature dependence of the viscosity of most polymers results in an expected ≈40% increase in viscosity with a decrease of 25°F. Applying that equation to the data presented in Mehaffy Table I results in estimated viscosities at 225°F (25°F less than the reported 250°F application temperature), that are above the maximum 1500 cps permitted by claim 1. (Br. 4.) Good concludes that “one skilled in the art would not look to 6 John P. Baetzold et al., Hot Melt Adhesive Comprising an Encapsulated Ingredient, U.S. Patent 5,827,913 (1998). 7 Supported by an excerpt from the Plastics Technology Handbook, 4th ed., of record and presented in the Evidence Appendix to the Brief. Appeal 2011-002550 Application 10/613,409 5 Mehaffy to develop an adhesive that can be applied at temperature [sic] below 250°F.” (Id. at 5, 3d full para.) We do not understand the Examiner to have found that the particular adhesives reported by Mehaffy in Table I can be applied at 200°F. Rather, the Examiner (Ans. 4, 1st full para.) expressly relied on Mehaffy’s description of the invention at paragraph [0030], which states that the adhesives are: characterized by a viscosity less than about 3000 cps at 135° C [275°F]. They may be applied at temperatures of 200 to 300°F to provide superior adhesive bonds even when exposed to a wide variety of temperature conditions. . . . In addition, a bond formed by two pieces of corrugated case substrate held together by a ½” by 2” compressed bead can maintain a cantilever stress load of 2 to 2.5 psi for 24 hours at a temperatures at or above 115°F. (Mehaffy 5 [0030]; emphasis added.) Moreover, the Examiner found—and Good has not disputed—that Mehaffy discloses hot melt adhesive compositions within the scope of appealed claim 1. (Office Action mailed 9 June 2009 at 3, 2d para.; Ans. 4, 1st full para., citing Mehaffy paras. [0009]-[0018] and [0029], and 5, citing various Mehaffy paras.) While Good’s arguments might be persuasive of harmful error in a rejection for anticipation by Mehaffy, the rejection before us is based on obviousness. In such a situation, as our reviewing court has instructed, “[a] reference must be evaluated for all it teaches and is not limited to its specific embodiments.” In re Bode, 550 F.2d 656, 661 (CCPA 1977). Indeed, Mehaffy states expressly that the examples are provided “for illustrative purposes only.” (Mehaffy 5 [0035].) Mehaffy also repeatedly Appeal 2011-002550 Application 10/613,409 6 states that “[t]he adhesive compositions of the present invention can be applied at lower temperatures of 200 to 300°F yet still provide exceptional heat resistance.” (Mehaffy [0005]; [0008].) Moreover, Good has not disputed the Examiner’s findings that the compositions suggested by Mehafffy overlap those covered by the appealed claims. Under these circumstances, the burden was fairly shifted to Good to explain how the evidence of record shows that ordinary exploration of the ranges of compositions taught by Mehaffy would not have yielded, without undue experimentation, hot melt adhesives in which the heat stress value is within 100°F of an application temperature less than 250°F. Cf. In re Peterson, 315 F.3d 1325, 1329 (Fed. Cir. 2003) (“A prima facie case of obviousness typically exists when the ranges of a claimed composition overlap the ranges disclosed in the prior art.”) Particularly in light of the common inventor, Mehaffy, it is difficult to see that that burden is unreasonable. Good’s remaining arguments do not relate to limitations recited in claim 1. We are not persuaded that harmful error has been demonstrated in the Examiner’s rejections. C. Order We AFFIRM the rejection of claims 1-5, 8, 10, 12, 13, 22, and 25-29 under 35 U.S.C. § 103(a) in view of the teachings of Mehaffy. We AFFIRM the rejection of claims 6 and 7 under 35 U.S.C. § 103(a) in view of the combined teachings of Mehaffy and Baetzold. Appeal 2011-002550 Application 10/613,409 7 No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
