DENNETT, Administrative Patent Judge. DECISION ON APPEAL 1 STATEMENT OF THE CASE Appellants2 appeal under 35 U.S.C. § 134 from rejection of claims 28-30, 34, 36--44, 46, 47, and 49-57. We have jurisdiction under 35 U.S.C. § 6(b ). We affirm. 1 In our opinion below, we refer to the Specification filed April 4, 2008 ("Spec."), the Final Action mailed February 21, 2014 ("Final Act."), the Appeal Brief filed August 21, 2014 ("App. Br."), the Examiner's Answer mailed September 25, 2014 ("Ans."), and the Reply Brief filed November 24, 2014 ("Reply"). 2 QinetiQ Limited is identified as the real party in interest. App. Br. 3. Appeal2015-002097 Application 12/078,755 The claims are directed to a method of identifying an object by use of thermally reflective material having a surface texture taking the form of a microstructure. Claim 28, reproduced below, is illustrative of the claimed subject matter: A method of identifying an object comprising the steps of: (i) providing one or more sheets of thermally reflective material having a surface texture comprising a plurality of reflecting elements, wherein each element has a first facet which is substantially reflective at thermal infrared wavelengths and wherein the respective first facets form an angle 5 ° < 8 < 40° with the plane of the sheet and wherein the first facets are aligned such that, in use, thermal radiation is reflected from a common direction; (ii) orienting said sheet of material on an object to reflect thermal radiation from a desired source; and (iii) monitoring the thermal radiation reflected from the sheet of material, wherein the surface texture takes the form of a micro-structure. App. Br. 25.

Final Act. 3--4, 9. OPINION Appellants argue claims 28-30, 34, 41--43, 46, and 49-57, including both independent claims 28 and 56, as a group. We limit our discussion of this group to one claim, i.e., claim 28; the other claims in the group will stand or fall with it. See 37 C.F.R. § 41.37(c)(l)(iv) (2012). Appellants separately argue patentability of each of claims 36-38 and 40, which we address separately. Rejection of claims 28-30, 34, 41-44, 46, 47, and 49-57 over Haynes in view of Merrill3 Appellants argue the rejection of claims 28-30, 34, 41--44, 46, 47, and 49-57 should be reversed for any of five reasons: (1) neither Haynes nor Merrill mentions the problem addressed by the claimed methods (App. Br. 11-12); (2) Haynes and Merrill would not have been combined (id. at 12- 15); (3) Haynes teaches away by encouraging diffuse multi-directional reflective facets (id. at 15-16); (4) the combination of Haynes and Merrill would not result in the claimed methods with a reasonable expectation of 3 The Examiner rejected claims 44 and 47 over Haynes in view of Merrill and further in view of Tyroler (Final Act. 9), which Appellants acknowledge in their Appeal Brief (App. Br. 10). Because Appellants do not separately address the Tyroler reference or claim 44 or 4 7 (both dependent from claim 28), we include them with this group. 3 Appeal2015-002097 Application 12/078,755 success (id. at 17-18); and (5) Haynes' Figure 2B does not teach or suggest a surface micro-structure (id. at 19-21 ). We affirm the rejection of claims 28-30, 34, 41-44, 46, 47, and 49-57 on the basis of the factual determinations and reasoning presented in the Final Action and the Examiner's Answer. We add the following. 1. Is the rejection improper because the cited prior art does not mention the problem addressed by the claimed methods? First, Appellants urge that the Examiner erred in rejecting the claims because neither Haynes nor Merrill mentions the problem addressed by the claimed methods. App. Br. 11. Appellants point out that independent claim 28 requires that the first facets of the reflecting elements are aligned such that, in use, thermal radiation is reflected from a common direction. Id. (emphasis in original). Appellants suggest that the claims are not obvious over the cited prior art because one of ordinary skill in the art would have had no reason to improve upon a problem not recognized by the prior art. Id. at 12 (citing Leo Pharm. Prods., Ltd. v. Rea, 726 F.3d 1346, 1354 (Fed. Cir. 2013)). Appellants' reliance on Leo Pharmaceutical is misplaced. The Federal Circuit limited Leo Pharrnaceutical to a situation in which one of ordinary skill in the art would not arrive at the claimed subject matter not only due to failure of the prior art to recognize and address the problern found by Appellants, but also due to the divergent teachings and express disclaimer in the prior art that would have precluded one of ordinary skill in the art from arriving at such combination. Leo Phann., 726 F.3d at 1355---- 56. In this case, neither teachings away nor express disclaimers exist In addition, Leo Pharmaceutical deals with unpredictable chemical 4 Appeal2015-002097 Application 12/078,755 technologies, unlike the claimed invention. J\1oreover, ""one of ordinary skill in the art need not see the identical problem addressed in a prior art reference to be motivated to apply its teachings." Cross Med. Prods., Inc. v. Medtronic Sofamor Danek, Inc., 424 F.3d 1293, 1323 (Fed. Cir. 2005). Appellants contend they made a "non-intuitive leap in the field of identification marking," permitting configuration of a vertical surface to undergo cold sky reflection. App. Br. 12. However, Haynes discloses thermally reflective material oriented vertically or near vertically. Final Act. 5 (citing Haynes Fig. 2). Furthermore, independent claim 28 does not require configuration of a vertical surface.4 App. Br. 25. In addition, the Examiner notes that Haynes discloses a reflective head constructed of fabric or plastic film covered with a cold black reflection material in which the cold black reflecting surface has a saw tooth configuration that provides a plurality of facets at an optimum angle relative to the cold black sky. Ans. 2 (citing Haynes col. 4, Fig. 2B). Figure 2B of Haynes is reproduced below: 4 Dependent Claim 30 requires thermally reflective material to be oriented vertically or near-vertically, but Appellants have not separately argued for patentability of claim 30, thus it stands or falls with claim 28. 5 Appeal2015-002097 Application 12/078,755 Figure 2B depicts a side view of a rotating heat emitting beacon ( 10) with a double-sided passive cold black reflecting surface (30) having a saw tooth configuration (31) providing a plurality of facets (32). The Examiner finds that "an optimum angle relative to the cold black sky" disclosed by Haynes is inconsistent with Appellants' contention that Haynes teaches only a plurality of random facet angles. Id. at 4. We agree, and draw the reader's attention to Haynes' disclosure that the cold black reflection material can be "stretched over a frame to provide a flat or curved reflective surface." Haynes col. 4, lines 3-5. "Stretching" the cold black reflective material is also inconsistent with Appellants' position that Haynes' teachings are limited to reflective material that is "creased and crumpled." In use, according to the Examiner, Haynes' saw tooth configuration, as shown in Fig. 2B, reflects thermal radiation from a common direction. Ans. 8. For example, Haynes discloses that: a plurality of surface elements can be arranged, very much like a Venetian blind, each of which is coated with a passive cold black surface. This surface can be seen at a distance by a thermal imaging camera as a combined black image, which can be made to flash, as each element is rotated through an angle. This arrangement has also the advantage of being unidirectional. Haynes col. 2, lines 55-62 (emphasis added). "Unidirectional" suggests that the surface is reflecting thermal radiation from a common direction. vVe agree with the Examiner for the reasons stated. On these facts, we find Appellants' argument that the rejection is improper because neither Haynes nor Merrill mentions the problem addressed by the claimed methods to be unpersuasive. 6 Appeal2015-002097 Application 12/078,755 2. Would one of ordinary skill in the art combine Haynes and Merrill? Second, Appellants argue that Haynes and Merrill would not have been combined. App. Br. 12. Essentially, Appellants argue that Merrill is non-analogous art to the claimed invention and would not be combined with Haynes. To rely upon a reference as a basis for an obviousness rejection of Appellants' claims, the reference must either (1) be in the field of the inventor's endeavor or (2) be reasonably pertinent to the particular problem with which the inventor was concerned. In re Kahn, 441F.3d977, 987 (Fed. Cir. 2006). A reference is reasonable pertinent to the problem based on the judgment of a person of ordinary skill in the art. In re Oetiker, 977 F.2d 1443, 1447 (Fed. Cir. 1992). Appellants urge that Merrill "teaches multi-layered optical films ... having strain induced birefringent properties," and "does not teach that such birefringent films should be thermally reflective." App. Br. 13 (emphasis in original). Appellants further urge that Merrill focuses on visible, as indicated by the wavelength of light at which the indices of refraction are determined. Id. (citing Merrill ,-i,-i 58-60). The Examiner points out that Merrill states that various of its embodiments can be used to operate at different wavelengths of electromagnetic radiation, and uses the term "light" to refer to electromagnetic radiation including the infrared spectrum. Ans. 3 (citing Merrill ,-i 4 7). The Examiner finds, and we agree, that Merrill thus teaches thermally reflective films, which is reasonably pertinent to the claimed subject matter. 7 Appeal2015-002097 Application 12/078,755 With respect to Haynes, Appellants contend that the reference "relates to an entirely different field of active thermal identification devices, and is concerned that with a macroscopic beacon device in which contrast can be improved by using a passive cold reflection surface." App. Br. 13. (emphasis in original). Appellants argue that Haynes is not concerned with passive thermal identification devices themselves, or methods of improving them, and does not teach either forming a microstructure or careful control of reflective facets. Id., at 13-14. Haynes teaches that there are two approaches to thermal beacons, active and passive, with the passive approach using material that is thermally reflective. Haynes col. 1, lines 49-50, 59-60. The Examiner points out that Haynes discloses a signal beacon that "utilizes detachable strips of a passive reflective material" ... "which can only been seen through a thermal imaging camera .... The reflecting cold black surfaces, i.e., coated with a passive cold emission material, need not necessarily rotate." Ans. 4 (citing Haynes col. 2-3). On this basis, the Examiner correctly finds that Haynes discloses passive thermal identification devices. Id. Appellants contend that Haynes does not teach forming a microstructure. App. Br. 13-14. We note that the Examiner does not rely on Haynes for teaching the microstructure of the claims; rather, the Examiner relies on Merrill for disclosure of a microstructure. Final Act. 4. Appellants cannot show non-obviousness by attacking references individually where the rejection is based on the teaching of a combination of references. In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). In response to Appellants' argument that Haynes does not teach careful control of reflective facets (App. Br. 14), the Examiner again 8 Appeal2015-002097 Application 12/078,755 contends that Haynes' disclosure of a "cold black reflecting surface [with] a saw tooth configuration that provides an optimum angle relative to the cold black sky" is inconsistent with Haynes teaches only a plurality of random facet angles. Ans. 4. In contending that Haynes and Merrill cannot be combined, Appellants argue that one of ordinary skill in the art seeking to improve upon Haynes would not consult prior art concerned with structured optical films (such as Merrill). App. Br. 14. The Specification states that "[t]he present invention relates to a reflective material and, in particular, to a material which is reflective in the thermal infrared and/or near infrared wavebands." Spec. 1, lines 5-6. The Examiner correctly finds that Merrill is reasonably pertinent to the particular problem with which Appellants are concerned: "reflective material ... which is reflective in the thermal infrared and/or near infrared wavebands"). It would have been obvious for one of ordinary skill in the art at the time of the claimed invention to consult prior art concerning structured optical reflectors (Merrill) to select known conventional heights for the unspecified height of the plurality of facets in Haynes in order to form structured surface reflectors at an optimum angle relative to the cold black sky. Final Act. 15. Thus, we do not find improper hindsight reasoning in the Examiner's combination of references. 3. Does Haynes teach away from the claimed invention? Appellants' third argument for patentability over the obviousness rejection is that Haynes teaches away from the claimed invention by encouraging diffuse multi-directional reflective facets. App. Br. 15. Appellants cite Haynes' disclosure that "the efficiency of the passive 9 Appeal2015-002097 Application 12/078,755 reflective material will be enhanced if it is creased and crumpled to form a multitude of reflective facets." Id. at 15 (quoting Haynes col. 2, lines 37- 40). Appellants contend that one of ordinary skill in the art would view a "creased and crumpled" reflective material as having a plurality of differently oriented facets that result in diffuse reflection, referring for support to documents filed in an Information Disclosure Statement on February 6, 2014. Id. According to the Examiner, "creased and crumpled" as used in Haynes expressly teaches a saw tooth configuration providing a plurality of facets which are not random facets that result in diffuse reflection. Ans. 7 (emphasis in original). The Examiner explains that the "optimum angle relative to the cold black sky," as taught in Haynes, is inconsistent with random facet angles. Id. at 7-8. In addition, Haynes makes several statements that indicate the reflective angles are not random. For example, Haynes teaches "[i]t is known that passive cold emission can be 'reflected' by means of a reflective surface which is suitably coated to prevent or minimize any reflected light" (Haynes col. 2, lines 16-19 (emphasis added)); random facet angles would not prevent or minimize reflected light. Haynes teaches the "Venetian blind" arrangement, which has the stated advantage of being unidirectional (id. col. 2, lines 55-62); "unidirectional" is not consistent with random facet angles. Haynes teaches that the reflective head is constructed of plastic or film covered with cold black reflection material stretched over a frame to provide a flat or curved reflective surface (id. col. 4, lines 1-5); "stretching" the material is inconsistent with creating only random facets angles. Although Haynes claims a "creased and crumpled" passive cold black reflection surface, its teachings are broader. 10 Appeal2015-002097 Application 12/078,755 "Teaching away" requires more than the mere expression of a general preference. Galderma Labs., L.P., v. Tolmar, Inc., 737 F.3d 731, 738 (Fed. Cir. 2013). Where, as here, the prior art reference does not "criticize, discredit or otherwise discourage investigation into the invention claimed," the disclosure does not amount to a teaching away. Id. 4. Does the combination of Haynes and Merrill result in the claimed methods with a reasonable expectation of success? Appellants' fourth argument for patentability over Haynes and Merrill is that the combination would not result in the claimed methods with a reasonable chance of success. App. Br. 17. A reasonable expectation, not absolute predictability, of success is required for a prima facie case of obviousness. In re Kubin, 561F.3d1351, 1360 (Fed. Cir. 2009). Whether one of ordinary skill in the art would have had a reasonable expectation that a particular combination of references would work is a pure question of fact. Alza Corp. v. Mylan Lahs., Inc., 464 F.3d 1286, 1289 (Fed. Cir. 2006). Here, Appellants argue that Haynes "encourages" a surface which is creased and crumbled, and combining such with Merrill would lead to a method in which one or more sheets have random reflecting facets in a microstructure, hence more diffuse reflection properties. App. Br. 17. The issue of Haynes' teaching regarding "creased and crumbled" reflective surfaces is dealt with above, where we find that Haynes' disclosure is not limited to creased and crumpled cold, black reflection materials with diffuse, random facet angles. Likewise, we previously addressed Appellants' contention that Merrill is incompatible with Haynes and found to the contrary. 11 Appeal2015-002097 Application 12/078,755 Appellants' suppositions ("it is believed that the multilayer film of Merrill would require a large number of polymer layers so as to provide the required refractive index changes" and "any non-uniform deformation of film imparted by embossing methods is likely to cause stray optical effects" (App. Br. 17-18)) are attorney argument which cannot take the place of evidence lacking in the record. Estee Lauder Inc. v. L 'Orea!, S.A., 129 F.3d 588, 595 (Fed. Cir. 1997). Appellants' argument that the combination of Haynes and Merrill would not result in the claimed methods with a reasonable expectation of success is not persuasive. 5. Haynes' Figure 2B does not teach or suggest a surface micro- structure? Appellants contend that Haynes' Figure 2B does not teach or suggest a surface microstructure. App. Br. 13. As stated above, the Examiner does not rely on Haynes for the teaching of a surface microstructure. Instead, the Examiner relies on Merrill for this disclosure. Final Act. 4. Non- obviousness cannot be shown by attacking references individually where the rejection is based on the teaching of a combination of references. In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). On this record, Appellants have not convinced us of reversible error in the Examiner's rejection of claims 28-30, 34, 41--44, 46, 47, and 49-57. Thus, we affirm rejection of these claims. Rejection of claim 36 over Haynes in view of Merrill Claim 36 depends on claim 28, and further requires that the first facets form substantially the same angle 8. App. Br. 26 (Claims App'x). 12 Appeal2015-002097 Application 12/078,755 Appellants dispute the Examiner's finding that Haynes discloses this limitation, arguing that when a reference does not disclose that the drawings are to scale and is silent as to dimensions, arguments based on measurement of the drawing features are of little value. Id. at 22 (quoting MPEP § 2125). Appellants' argument is unpersuasive, as the Examiner has not based the rejection of claim 36 on measuring the drawings in Haynes. Instead, the Examiner relies on Haynes' disclosure that the passive cold black reflecting surface has a saw tooth configuration providing a plurality of facets "at an optimum angle relative to the cold black sky," finding that facets "at an optimum angle" form "substantially the same angle 8." Ans. 12. Appellants have not shown reversible error in the Examiner's rejection of claim 36. Rejection of claim 37 over Haynes in view of Merrill Dependent claim 37 requires the limitations of claim 28 with the additionai iimitation that the first facets iie in substantiaHy the same piane. App. B. 26 (Claims App'x). Appellants argue that Haynes' facets 32 are large, louvre-sized components, not a microstructure surface. Id. at 22. The Examiner responds that Appellants fail to cite any portion in Haynes that describes the dimensions in Figures 2B and 4B of Haynes, thus Appellants' argument is unpersuasive. Ans. 12. Figure 2B of Haynes shows a saw tooth configuration and Figure 4B shows louver configuration. Haynes Fig. 2B and 4B. In reply, Appellants urge that Haynes describes a macro- lamp- sized structure, and not a microstructure recited in the claims. Reply 3. Appellants also point out that it is the Patent Office's burden to establish obviousness, and urge that the Examiner has reversed that burden. Id. 13 Appeal2015-002097 Application 12/078,755 We agree with Appellants that the Examiner improperly placed the burden of showing the non-obviousness of claim 37 on Appellants. See Ans. 12. However, we consider the Examiner's error harmless, based on our opinions above. Changes that do not alter function are ordinarily obvious variations. See In re Rice, 341F.2d309 (CCPA 1965) (Examiner properly found that claimed dimensional relationship between collection chamber and walls of main air chamber "does not produce any different effect or result"); Gardner v. TEC Sys., Inc., 725 F.2d 1338 (Fed. Cir. 1984) (Where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device); In re Rose, 220 F .2d 459, 463 (CCPA 1955) ("the size of the article under consideration ... is not ordinarily a matter of invention"); In re Rinehart, 531 F .2d 1048, 1053 (CCPA 1976) (mere scaling up of a prior art process capable of being scaled up, if such were the case, would not establish patentability in a claim to an old process so scaled). Here Haynes teaches the structure, save for the microstmcture size, and Merrill teaches the microstmcture. As these references are combinable, as discussed above, together they render claim 37 obvious. Rejection of claim 38 over Haynes in view of Merrill Claim 38 claims the method of clam 28 wherein the surface texture takes the form of a uniform microstmcture having a repeating pattern of reflecting elements. App. Br. 26 (Claims App'x). 14 Appeal2015-002097 Application 12/078,755 Appellants contend that the saw tooth configuration in Figure 2B of Haynes more naturally corresponds to the recited sheet of the claim, which sheet acts as a substrate for the surface texture. Id. at 23. The Examiner references arguments that the term "facet" in Haynes is not used to describe the louver configuration illustrated in Figures 4A--4B, but is instead used to describe the saw tooth configuration illustrated in Figures 2A-2C of the reference. Ans. 10-11, 13. We find that the weight of the evidence better supports the Examiner's findings. Haynes discloses in text and drawings a saw tooth structure that one of ordinary skill in the art at the time of the invention would view as having a repeating pattern of reflecting elements. See Haynes Fig. 2B; col. 4, lines 10-14. As discussed above, Merrill teaches the microstructure size. Appellants have not shown the Examiner's rejection of claim 3 8 to be m error. Rejection of claim 40 over Haynes in view of Merrill Dependent claim 40 requires the method of claim 28 wherein the surface texture comprises a saw tooth texture. App. Br. 26 (Claims App'x). As with claim 38, Appellants contend that the saw tooth configuration in Figure 2B of Haynes more naturally corresponds to the recited sheet of the claim, which sheet acts as a substrate for the surface texture. Id. at 23. For the same reasons discussed with regard to claim 40 above, we find Appellants' argument unpersuasive. 15 Appeal2015-002097 Application 12/078,755 DECISION For the above reasons, the Examiner's rejection of claims 28-30, 34, 36-38, 40--43, 46, and 49-57 is AFFIRMED. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § l .136(a)(l )(iv). AFFIRMED 16 Copy with citationCopy as parenthetical citation
