GREENHUT, ANNETTE R. REIMERS, and PAUL J. KORNICZKY, Administrative Patent Judges. GREENHUT, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellant and Real Party in Interest, ResMed Ltd., appeal under 35 U.S.C. § 134 from a rejection of claims 1-28. We have jurisdiction under 35 U.S.C. § 6(b). We affirm-in-part. Appeal2018-003586 Application 14/070,677 CLAIMED SUBJECT MATTER The claims are directed to patient interface systems. Claim 1, reproduced below, is illustrative of the claimed subject matter: 1. Headgear for a patient interface configured to deliver a flow of breathable gas to a patient, the headgear comprising: an elastomer in the form of a strap adapted to position the patient interface in sealing engagement with the patient's airways, wherein a first side of said elastomer includes a first region with a surface that is textured to increase surface roughness and reduce surface tension and/or friction between the strap and the patient. REJECTIONS 1 Claims 1--4, 8, 9, 19, and 20 are rejected under 35 U.S.C. § I02(b) as being anticipated by Bullard (US 2,199,690, issued May 7, 1940). Claims 1--4, 8, 12, 19, 202, and 23-27 are rejected under 35 U.S.C. § I02(b) as being anticipated by Holloway (US 3,457,564, issued July 29, 1969). Claims 5 and 11 3 are rejected under 35 U.S.C. § I03(a) as being unpatentable over Bullard. Claim 7 is rejected under 35 U.S.C. § I03(a) as being unpatentable over Bullard and Wondka (US 2009/0183739 Al, issued July 23, 2009). 1 Several rejections based entirely or in part on Pirelli have been withdrawn by the Examiner. Ans. 3--4. 2 Although not included in the rejection statement (Final Act. 7), the Examiner appears to have intended to include claim 20 in the anticipation rejection based on Holloway. See Final Act. 9; Ans. 15-16. 3 Claim 10, which is nowhere discussed in the Final Action, appears to have been inadvertently included in this rejection in the Answer. Ans. 2. 2 Appeal2018-003586 Application 14/070,677 Claims 13-17 are rejected under 35 U.S.C. § I03(a) as being unpatentable over Bullard and Dougherty (US 5,428,844, issued July 4, 1995). Claim 18 is rejected under 35 U.S.C. § I03(a) as being unpatentable over Bullard, Dougherty, and Bart (US 6,220,916 B 1, April 24, 2001 ). Claims 1---6, 8, 9, and 19-28 are rejected under 35 U.S.C. § I03(a) as being unpatentable over Bullard and Sherman (US 2002/0177793 Al, issued November 28, 2002). Claim 7 is rejected under 35 U.S.C. § I03(a) as being unpatentable over Bullard, Sherman, and Wondka. Claims 13-17 are rejected under 35 U.S.C. § I03(a) as being unpatentable over Bullard, Sherman, and Dougherty. Claim 18 is rejected under 35 U.S.C. § I03(a) as being unpatentable over Bullard, Sherman, Dougherty, and Bart. OPINION The anticipation rejections of claims 1-4, 8, 9, and 19 over Bullard and claims 1-4, 8, 19, 26, and 27 over Holloway, are affirmed. The rejections of independent claim 1 as anticipated by either Bullard or Holloway both hinge on the same issue, the meaning of the claim recitation "textured to increase surface roughness and reduce surface tension and/or friction between the strap and the patient." App. Br. 9-12, 13-15; Reply. Br. 2-3, 4--5. Appellant contends that the generally similar surface features of Bullard (grooves 26/protuberances 27) and Holloway (ribs 20/dimples 21) relied upon by the Examiner to demonstrate the recited property of being "textured to increase surface roughness" (Final Act. 5---6, 3 Appeal2018-003586 Application 14/070,677 7-8), "contribute to the macroscopic shape of the straps [and] 'surface roughness' is a property of the surface finish of an object and is measured on a microscopic scale." App. Br. 10, 13. Although we recognize the term "surface roughness" may have a specific meaning in the context of engineering drawings or certain specifications, we disagree with Appellant that the term carries such a meaning in the context of claim 1. First, as the Examiner points out (Final Act. 5-8), paragraph 286 of Appellant's Specification states, "[a] textured surface finish may roughen the surface. The textured surface finish may comprise, for example, frosting, dimples or troughs, waves, etched, cross hatched, knurled." This provides examples of features that increase surface roughness without any mention or qualification that those features exist only at a microscopic scale. Appellant's argument that surface roughness would be the same for all parts of the Bullard and Holloway straps, including over their respective surface deviations (App. Br. 10, 13), relies on the assumption that "surface roughness" must be a quantity measured over a small enough sampling length so as to render those deviations inconsequential to the measurement. Appellant is correct in that surface roughness could be measured this way, such as by measuring Ra over a small enough sample length. However, we are not apprised of any language in claim 1 that requires surface roughness to be measured over such a minute sampling length so as to preclude the respective surfaces of Bullard and Holloway from being considered "textured in increase surface roughness" as recited in claim 1. Appellant's Specification states, at paragraph 294 (with emphasis added), "[p ]referably, surface texture or surface roughness is measured by Ra. Ra is an average measurement of the peaks and valleys over an area of the material. In this description, the Ra 4 Appeal2018-003586 Application 14/070,677 values are quoted as micro meters (µm)." Although the claims are interpreted in light of the specification, limitations from the specification, particularly those described only as "preferable," are not read into the claims. In re Van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993). Appellant's argument is also inconsistent with dependent claim 4, which suggests claim 1 does not preclude surface roughness, when measured in terms of Ra specifically, from being zero-something that could theoretically happen if the surface features exist on a scale sufficiently larger than the Ra sampling length as Appellant alleges they do in Bullard and Holloway. Accordingly, in light of the Specification, we disagree with Appellant that the recited phrase "textured to increase surface roughness" serves to exclude the relied- upon texturing of Bullard or Holloway. The next part of Appellant's argument focuses on the functional recitation associated with the texturing: "reduce surface tension and/or friction between the strap and the patient." There does not appear to be any disagreement between Appellant and the Examiner that the cited surface features of Bullard (26, 27) and Holloway (20, 21) serve different purposes: reducing slippage with their respective buckles (Bullard 23 (p. 2, col. 2, 11. 14--18); Holloway 22 (col. 2, 11. 47-58)), and that neither Bullard nor Holloway discusses what the effects of the features would be interfacing with a patient. The Examiner takes a reasonable and sound position that, as the structures are the same or similar to those described in the Specification, the same results would be expected. Ans. 7-8, 14--15 ( citing Spec. paras. 286,287, 294, 297). Appellant, citing the same paragraphs cited by the Examiner, asserts without further technical explanation on this point, that "Appellants' specification discloses that the types of 'dimples', 5 Appeal2018-003586 Application 14/070,677 'depressions', 'troughs' and 'knurled portions' that form the 'textured surface' are the types that reduce surface tension and/or friction between a headgear strap and a patient." Reply Br. 3, 5. However, we find nothing in the cited paragraphs distinguishing, for example, a dimple that does "reduce surface tension and/or friction between a headgear strap and a patient" from a dimple that does not. In other words, neither Appellant's arguments nor Appellant's Specification provides any evidence or technical reasons to conclude, for example, that the dimples of Holloway would function any differently from the dimples of Appellant. The court in Swinehart states that: [W]here the Patent Office has reason to believe that a functional limitation asserted to be critical for establishing novelty in the claimed subject matter may, in fact, be an inherent characteristic of the prior art, it possesses the authority to require the applicant to prove that the subject matter shown to be in the prior art does not possess the characteristic relied on. In re Swinehart, 439 F.2d 210,213 (CCPA 1971); see also MPEP § 2112(V) (citing In re Schreiber, 128 F.3d 1473, 1478 (Fed. Cir. 1997)). Appellant has not done so. Claims differing from the prior art by no more than the recitation of a result or latent characteristic do not distinguish those claims over the prior art. See In re Wiseman, 596 F.2d 1019, 1023 (CCPA 1979) ("[Appellants] are, in effect, arguing that a structure suggested by the prior art, and, hence, potentially in the possession of the public, is patentable to them because it also possesses an inherent, but hitherto unknown, function which they claim to have discovered. This is not the law.") (discussed, along with similar cases, at MPEP § 2145(II)); Bristol-Myers Squibb Co. v. Ben Venue Labs., Inc., 246 F.3d 1368, 1376-77 (Fed. Cir. 2001). 6 Appeal2018-003586 Application 14/070,677 For the foregoing reasons, we sustain the Examiner's rejections of claim 1 as being anticipated by Bullard and also by Holloway. Appellant does not present separate arguments for the anticipation rejection of claims 2--4, 8, 9, and 19 based on Bullard or for the anticipation rejection of claims 2--4, 8, 19, 26, and 27 based on Holloway. Accordingly, we sustain the respective anticipation rejections against these claims as well. See 37 C.F.R. § 4I.37(c)(l)(iv). The anticipation rejections of claim 20 over Bullard and claims 20 and 23- 25 over Holloway are reversed. The Examiner's position with regard to claim 20 is that the term "coating" is a product-by-process limitation, which therefore does not distinguish the claim over Bullard or Holloway. Ans. 9-10; 16-16. First, although "coating" may be used as a verb to describe a process by which something is formed, it may also, as is the case here, be used as a noun connoting a structural meaning. See MPEP § 2113 (!)(giving examples of terms, such as welded, that may have a structural meaning typically resulting from a process bearing a name having the same root word). Second, even if the word coating was used in a manner that only referred to the process by which a textured surface is placed on the strap, it would be incumbent upon the Examiner to show identity with the final prior-art structure being relied on. For example, one would expect a coating process to result in a structural configuration that is, at least, layered. See MPEP § 2113 (II) ( emphasis added) ("Once the examiner provides a rationale tending to show that the claimed product appears to be the same or similar to that of the prior art, although produced by a different process, the burden shifts to 7 Appeal2018-003586 Application 14/070,677 applicant ... "). The Examiner has provided no such reasoning along these lines. For the foregoing reasons, we do not sustain the Examiner's anticipation rejection of claim 20 over Bullard and that of claims 20 and 23- 25 over Holloway. The obviousness rejections of claims 1-9 and 13-28 based on Bullard and Sherman, with or without the cited additional references, are reversed. In the rejection of independent claim 1 predicated on the combination of Bullard and Sherman, the Examiner indicates that "Bullard does not expressly disclose the manner by which the textured surface can reduce friction." Final Act. 16. Above, we discussed the reasons why Bullard need not make such an express disclosure to support a finding of anticipation, namely, because the same structure would be expected to exhibit the same behavior when worn by a patient. However, to the extent the Examiner relies on Sherman to fill in this information, the Examiner's reliance is misplaced. Appellant correctly points out (App. Br. 17) that the friction-reducing mechanism of Sherman's Teflon® or similar material does not operate by reducing surface tension like the various forms of texturing described in Appellant's Specification (see para. 287). Thus, the Examiner's conclusion that it would have been obvious "to include an elastic low friction material to reduce surface tension" (Final Act. 17) lacks rational underpinnings in the record before us. Further, because neither Sherman nor the Examiner provides any evidence pertaining to the texture of Teflon® or similar materials, making a modification to Bullard to include one of those materials does not supply the subject matter for which the Examiner turns to a secondary reference: 8 Appeal2018-003586 Application 14/070,677 "Bullard does not expressly disclose the manner by which the textured surface can reduce friction." As the Examiner has not supported the rejection of claim 1 predicated on Bullard and Sherman with a cogent explanation demonstrating the reasons for unpatentability, we do not sustain the Examiner's rejection of independent claim 1, or its dependent claims 2-6, 8, 9, 19, 21, 22, and 26-28 based on Bullard and Sherman. As the additional references cited by the Examiner do not remedy this shortcoming we also do not sustain the rejections against claims 7 and 13-18 based on Bullard, Sherman and one or more of W ondka, Dougherty, and Bart. With regard to claim 20, the Examiner makes a statement that is somewhat difficult to parse grammatically but appears to relate to the same unsupported and seemingly inaccurate statements discussed above concerning claim 1: "Consequently, the relationship where a low fiction material is being used, produces a surface texture that smoother, which results in a surface roughness where there are a higher number peaks and valleys, in tum a higher Ra value, over the material to facilitate a 'strap to slide or slip' (Paragraph 00297)." Final Act. 18. The Examiner's product-by- process reasoning (Final Act. 18) is flawed for reasons already discussed above. As the Examiner has not supported the rejection of claim 20 predicated on Bullard and Sherman with a cogent explanation demonstrating the reasons for unpatentability, we do not sustain the Examiner's rejection of independent claim 20, or its dependent claims 23-25, based on Bullard and Sherman. 9 Appeal2018-003586 Application 14/070,677 The anticipation rejections of claim 12 over Holloway is reversed. Appellant correctly argues, "[ t ]he Examiner fails to provide any evidence or explain how Holloway discloses the 'parting line' feature of claim 12." App. Br. 22. The Examiner includes claim 12 in the rejection statement but never articulates a specific basis for rejection. Final Act. 7-9. Examination "shall be complete with respect ... to the patentability of the invention as claimed." 37 C.F.R. § 1.104(a)(l). "The reasons for any adverse action ... will be stated in an Office action and such information or references will be given as may be useful in aiding the applicant ... to judge the propriety of continuing the prosecution" 3 7 C.F .R. § 1.104( a )(2 ). "The pertinence of each reference, if not apparent, must be clearly explained and each rejected claim specified." 37 C.F.R. § 1.104(c)(2). Because it is unclear from the record how the teachings and disclosures of Holloway are being applied by the Examiner to reject claim 12, we do not sustain the rejection of claim 12 as being anticipated by Holloway. The obviousness rejection of claims 5 and 11 over Bullard is reversed. In rejecting claim 5, the Examiner reasoned: In light of the relationship between Ra value and surface roughness, it would have been obvious [] to modify the Ra value of the strap with respect to the desired surface finish, texture, and reduced frictional engagement, since it has been held that where the general conditions of a claim are disclosed in the prior art discovering the optimal or workable ranges involves only routine skill in the art. Moreover, Applicant has not asserted the specific Ra value range provides a particular advantage, solves a stated problem, or serves a purpose different from that of reducing friction by providing a smooth finish for engagement of the strap about the patient: thus, the use of the specific Ra value range lacks criticality in its design. 10 Appeal2018-003586 Application 14/070,677 Final Act. 11-12. In rejecting claim 11, the Examiner reasoned: In light of the relationship between radius of curvature and the ability of the edges of the strap to not be sharp, it would have been obvious [] to modify the radius of curvature of the strap with respect to the desired surface finish, texture, and reduced frictional engagement, since it has been held that where the general conditions of a claim are disclosed in the prior art discovering the optimal or workable ranges involves only routine skill in the art. Moreover, Applicant has not asserted the specific radius of curvature provides a particular advantage, solves a stated problem, or serves a purpose different from that of reducing friction by providing a smooth finish for engagement of the strap about the patient; thus, the use of the specific radius of curvature lacks criticality in its design. Final Act. 12. Both rejections mention "reducing friction by providing a smooth finish for engagement of the strap about the patient." Both the basis and the relevance of this statement are unclear. As discussed above, Appellant's Specification discusses providing texture, the opposite of a smooth surface, to reduce friction between strap and patient. Bullard discusses providing similar features to decrease slip between the strap and buckle. The point the Examiner is attempting to make regarding reducing friction with a smooth surface is unclear. The Examiner's comments regarding frictional engagement also do not appear to be relevant to the radius aspect of claim 11. Although certain dimensional characteristics of the claimed subject matter may be the product of "routine optimization" or "design choices," the Examiner must always support a rejection with a fact-specific analysis to explain why the claimed subject matter would have been obvious despite 11 Appeal2018-003586 Application 14/070,677 these differences between the subject matter claimed and the prior art. In re Kahn, 441 F .3d 977, 988 (Fed. Cir. 2006) ( citation omitted) ("[R ]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.") ( Cited with approval in KSR Int'! v. Teleflex Inc., 550 U.S. 398,418 (2007)). In the case of routine experimentation, it is incumbent upon the Examiner to explain, or provide evidence to demonstrate, the parameter optimized was recognized as a result-effective variable. App. Br. 24--25 (citing MPEP § 2144.05(II)(B) and In re Antonie, 559 F.2d 618 (CCPA 1977)). In the case of design choices, the Examiner should provide a cogent explanation why, despite differences in the claimed structure, the function it performs would not differ from that of the prior art. In re Chu, 66 F.3d 292, 299 (Fed. Cir. 1995) (citing In re Gal, 980 F.2d 717 (Fed. Cir. 1992)). The Examiner's rejections of claims 5 and 11 are not supported by these types of particularized, fact- specific analyses. Substituting per se rules for the particularized inquiry required by section 103, as appears to have been done here, necessarily produces erroneous results. In re Ochiai, 71 F.3d 1565, 1571 (Fed. Cir. 1995). The general purposes of the Ra value and radius are explained in paragraphs 297 and 303, respectively. Although, pertaining to specific dimensional recitations, criticality and/or unexpected results may, if present, lend support to a conclusion of non-obviousness (MPEP §§ 2144.05, 2145), "the absence of objective evidence is a neutral factor" in the obviousness inquiry (Medtronic, Inc. v. Intermedics, Inc., 799 F.2d 734, 739 n.13 (Fed. Cir. 1986) ( citations omitted)) and "does not dictate a conclusion of obviousness" (Kansas Jack, Inc. v. Kuhn, 719 F.2d 1144, 1150 (Fed. Cir. 12 Appeal2018-003586 Application 14/070,677 1983) ). Even absent evidence of criticality, the Examiner does not provide sufficient evidence or explanation to support the Examiner's conclusion of obviousness with regard to the subject matter of claims 5 and 11. See, e.g., In re Stepan Co., 868 F.3d 1342, 1348 (Fed. Cir. 2017). The obviousness rejections of claims 7 and 13-18 that do not rely on Sherman are affirmed. These rejections are affirmed because they are not separately argued. DECISION The anticipation rejections of claims 1--4, 8, 9, and 19 over Bullard and claims 1--4, 8, 19, 26, and 27 over Holloway, are affirmed. The anticipation rejections of claim 20 over Bullard and claims 20 and 23-25 over Holloway are reversed. The obviousness rejections of claims 1-9, and 13-28 based on Bullard and Sherman, with or without the cited additional references, 4 are reversed. The anticipation rejection of claim 12 over Holloway is reversed. The obviousness rejection of claims 5 and 11 over Bullard is reversed. The obviousness rejections of claims 7 and 13-18 that do not rely on Sherman 5 are affirmed. 4 Claim 7 as being unpatentable over Bullard, Sherman, and Wondka; claims 13-17 as being unpatentable over Bullard, Sherman, and Dougherty; and claim 18 as being unpatentable over Bullard, Sherman, Dougherty, and Bart. 5 Claim 7 as being unpatentable over Bullard and W ondka; claims 13-17 as being unpatentable over Bullard and Dougherty; and claim 18 as being unpatentable over Bullard, Dougherty and Bart. 13 Appeal2018-003586 Application 14/070,677 No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
