GROUPING OF CLAIMS Based on Appellant's arguments, we decide the appeal of the §103 rejection R1 of claims 14, 17, 18 and 22 on the basis of representative claim 22. See 37 C.F.R. § 41.37(c)(1)(vii)(2004). 2 Based on Appellant's arguments, we decide the appeal of the §103 rejection R4 of claims 1 and 4 on the basis of representative claim 1. (Id.). We address the §103 rejections R2, R3, and R5-R10 of the remaining claims separately, infra. ANALYSIS R1. Regarding the claim 22 limitation "[c2] an electronic model of a fitting configured to couple to a clinical gas delivery system;" Appellant contends: 2 Appellant filed a Notice of Appeal on June 2, 2010. The date of filing the Notice of Appeal determines which set of rules applies to an Ex Parte appeal. If a notice of appeal is filed prior to January 23, 2012, then the 2004 version of the Board Rules last published in the 2011 edition of Title 37 of the Code of Federal Regulations (37 C.F.R. § 41.1 et seq.) applies to the appeal. See also MPEP Rev. 8, July 2010. Appeal 2011-012378 Application 11/768,457 5 [T]he Examiner appears to maintain that the electronic model of the fitting is somehow disclosed by a physical “pipe like member (1202) [that] may be attached to the body member (1201) . . . .” Examiner's First Answer at 27. (citing Geng at 88). A physical pipe-like member that is physically attached to another component, however, is not “an electronic model of a fitting configured to couple to a clinical gas delivery system,” as recited in Claim 22. (Second Reply Br. 4). We are not persuaded by Appellant's contentions because Appellant does not consider all the teachings and suggestions of Geng pointed to by the Examiner. (Ans. 26). The Examiner finds, and we agree, that Geng's description of forming electronic mask models of different masks (¶[0086]; Figs. 10, 11C, and 11D) and Geng's description of forming a custom designed nostril mask, based on the acquired 3D measurement data, with a gas fitting (¶[0088]; Fig. 12), would have taught or suggested the claimed [c2] “an electronic model of a fitting configured to couple to a clinical gas delivery system.” (Ans. 19, 24). We find Geng's laying ([c] "merging") [c1] the computer model of a human face (¶[0086]; Figs. 11C, 11D and 12; Ans. 24-25; face model) with [c2] a electronic model of a mask having a gas fittings (see above analysis; Ans. 24) would have taught or suggested the contested limitation. (Ans. 24- 25; ¶[0086];¶[0088]; Figs. 10, 11C, and 11D).3 Moreover, we find a skilled 3 The Supreme Court has determined that the conclusion of obviousness can be based on the interrelated teachings of multiple patents, the effects of demands known to the design community or present in the marketplace, and the background knowledge possessed by a person having ordinary skill in the art, and an obviousness “analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court Appeal 2011-012378 Application 11/768,457 6 electronic gas mask modeler would have added a gas mask feature, such as a gas fitting/opening, to a 3D custom face fit electronic mask model because it would have been common sense to add standard features to such models. For these reasons, on this record we are not persuaded the Examiner erred. Accordingly, we sustain the rejection of claim 22 and of claims 14, 17 and 18, which fall therewith. R2. Appellant contends claims 15 and 19 are patentable for the reasons previously argued for claim 22. (App. Br. 12, 14). However, we are not persuaded the Examiner erred regarding the rejection of claims 15 and 19 for the same reasons given above regarding claim 22. R3. Appellant contends claim 21 is patentable for the reasons previously argued for claim 22. (App. Br. 14). However, we are not persuaded the Examiner erred regarding the rejection of claim 21 for the same reasons given above regarding claim 22. R4. Claim 1 Regarding the claim 1 limitation “the fitting and the body form one integral piece of the polymerized photopolymer material,” Appellant contends: [T]he Examiner fails to indicate any portion of Smalldone allegedly disclosing photopolymer, much less a fitting and the can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398, 418 (2007). See also DyStar Textilfarben GmbH & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1368 (Fed. Cir. 2006). Appeal 2011-012378 Application 11/768,457 7 body that form one integral piece of the polymerized photopolymer material. (Second Reply Br. 6). Appellant's contentions are not persuasive because Appellant attacks the references individually and does not fully consider Hull's teachings as relied on by the Examiner. (Second Reply Br. 6; Second Ans. 5-7). We agree with the Examiner that Hull teaches or suggests use of a “polymerized photopolymer material” because Hull teaches the creation of a mask using a UV curable chemical exposed to a UV beam. (Second Ans. 7). We further agree with the Examiner that Smalldone teaches or suggests forming a mask as "one integral piece" of material, such that the combination of references would have taught or suggested the contested limitation to one of ordinary skill in the art. (Second Ans. 7-8). Appellant further contends: Tellingly, the Examiner's Second Answer does not even address, much less rebut the reasoning asserted in Appellant's First Reply Brief as to why Smalldone teaches away from the proposed combination. Because the Examiner appears to no longer even dispute that Smalldone teaches away from the proposed combination, Smalldone cannot properly be combined with Rogers and Hull, or any other reference for that matter, to teach a number of limitations of Claim 1. (Second Reply Br. 7). We are not persuaded by the Appellant's contentions. Regarding Appellant's “teaching away” argument, we note that teaching an alternative or equivalent method does not teach away from the use of a claimed method. See In re Dunn, 349 F.2d 433, 438 (CCPA 1965). Thus, “[t]he prior art's mere disclosure of more than one alternative does not constitute a teaching Appeal 2011-012378 Application 11/768,457 8 away from any of these alternatives because such disclosure does not criticize, discredit, or otherwise discourage the solution claimed. . . .” In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Here, the Examiner finds, and we agree, that Smalldone teaches an alternative method of mask construction, but does not criticize, discredit or otherwise discourage the claimed mask construction method using photopolymers. (Ans. 27). For this reason, on this record we are not persuaded the Examiner erred. Accordingly, we sustain the rejection of claim 1 and of claim 4, which falls therewith. CLAIM 5 Regarding the claim 5 limitation “wherein the stereolithography model further comprises an electronic model selected from the group consisting of . . . . an oral appliance,” Appellant contends: The Examiner does not dispute the fact that the Examiner relies solely on a physical feature of a wearable mask disclosed in Smalldone as allegedly curing the acknowledged deficiencies of Rogers and Hull regarding “an electronic model” that is either “a fitting model,” “an oral chamber model,” or “a receptacle model,” as recited in Claim 5. For at least the reasons discussed in Appellant's previous submittals to the Board, the Examiner's reliance on a physical mask feature of Smalldone as allegedly disclosing the claimed “electronic model,” as recited in Claim 5, is an incorrect and unreasonable interpretation of the claim. (Second Reply Br. 7-8). We agree with Appellant that the Examiner erred with respect to claim 5. Claim 5 requires “wherein the stereolithography model further comprises an electronic model selected from the group consisting of: a Appeal 2011-012378 Application 11/768,457 9 fitting model…an oral chamber model… and receptacle model . . . “ (emphasis added). We agree with Appellant the Examiner erred by relying on the physical mask of Smalldone as teaching or suggesting the claimed electronic model. (First Reply Br. 10; Ans. 27-29). Unlike the Geng reference applied to other claims, the Examiner has not shown Smalldone would have taught or suggested an electronic model “selected from the group consisting of: a fitting model . . . ; an oral chamber model . . . and a receptacle model . . . to an oral appliance,” as recited in the Markush group of claim 5 (Emphasis added).4 We therefore reverse the rejection of claim 5 and the rejections of claims 6-9, which depend from claim 5. R5. Appellant contends claim 2 is patentable for the reasons argued for claim 1. (App. Br. 16). However, we are not persuaded the Examiner erred regarding the rejection of claim 2 for the same reasons given above regarding parent claim 1. R8. Regarding independent claim 10, Appellant contends: The Examiner has now acknowledged multiple times that Rogers does not disclose a three-dimensional electronic model comprising an electronic model of a fitting configured to couple to a clinical gas delivery system, as recited in Claim 10. See, e.g., Final Office Action at 22, 24-25, and 27-28. The Examiner's Second Answer does not even address this missing limitation but rather merely offers the conclusory statement that “Appellant's arguments, on pages 9-12 with respect to claims 5- 4 In the event of further prosecution, we leave it to the Examiner to consider whether Geng teaches or suggests the claimed electronic model in claim 5. Appeal 2011-012378 Application 11/768,457 10 9 and 10-12, are not persuasive.” Examiner's Second Answer at 6. The Examiner's conclusory statement does not dispute the fact that the Examiner relies on a physical feature of a wearable mask as allegedly disclosing the claimed “electronic model of a fitting configured to couple to a clinical gas delivery system,” as recited in Claim 10. See Final Office Action at 18; see also Examiner's First Answer at 33. The Examiner's interpretation of an “electronic model" to mean a physical feature of a wearable mask is an incorrect and unreasonable interpretation of Claim 10. (Second Reply Br. 8). We have reviewed the Examiner's rejection of claim 10 and are persuaded that the Examiner erred with respect to claim 10. We agree with Appellant that the Examiner erred by relying on the physical mask of Bishop as teaching or suggesting the claimed electronic model. (First Reply Br. 11; Ans. 29-32). Unlike the Geng reference applied to other claims in this case, the Examiner has not shown that Rogers, Manners, or Bishop would have taught or suggested an electronic model of a fitting, as recited in claim 10.5 Therefore, we reverse the rejection R8 of claim 10. R9 and R10. Because the Examiner has not shown the additional cited references cure the deficiencies of the base combination of Rogers and Bishop relied on in claim10, we also reverse the Examiners the rejections R9 and R10 of claims 11 and 12 respectively, which each depend from claim 10. 5 In the event of further prosecution, we leave it to the Examiner to consider whether Geng teaches or suggests the “electronic model” recited in claim 10. Appeal 2011-012378 Application 11/768,457 11 DECISION We affirm the Examiner's rejections of claims 1, 2, 4, 14, 15, 17-19, 21 and 22 under § 103. We reverse the Examiner's rejections of claims 5-12 under § 103. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(1)(iv). See 37 C.F.R. § 41.50(f). AFFIRMED-IN-PART Klh Copy with citationCopy as parenthetical citation
