WARREN, PETER F. KRATZ, and CATHERINE Q. TIMM, Administrative Patent Judges. WARREN, Administrative Patent Judge. DECISION ON APPEAL Applicants appeal to the Board from the decision of the Primary Examiner finally rejecting claims 1 through 7, 27 through 34, and Appeal 2006-3072 Application 10/419,763 36 through 43,1 in the Office action mailed June 15, 2005. 35 U.S.C. §§ 6 and 134(a) (2002); 37 C.F.R. § 41.31(a) (2005). We affirm the decision of the Primary Examiner. Claims 1 and 2 illustrate Appellants’ invention of a liquid crystal device, and are representative of the claims on appeal: 1. A liquid crystal device comprising first and second opposed spaced-apart walls enclosing a layer of a liquid crystal material, electrodes on at least one cell wall for applying an electric field across at least some of the liquid crystal material, at least a part of the inner surface of the first cell wall including a first surface layer formed from a polymerised aligned mesogenic material, and at least a part of the inner surface of the second cell wall including a second surface layer formed from a polymerised [sic] aligned mesogenic material, which surface layers are in contact with the liquid crystal material at first and second interfaces respectively; the anchoring energy at the first interface differing from the anchoring energy at the second interface. 2. A device as claimed in claim 1, wherein the difference in anchoring energies results from polymerisation [sic] of the mesogenic material of the surface layers at different temperatures. The Examiner relies on the evidence in these references: Nakamura US 5,686,019 Nov. 11, 1997 Walton US 6,201,588 B1 Mar. 13, 2001 Martinot-Lagarde US 6,452,573 B1 Sep. 17, 2002 Appellants request review of the ground of rejection of claims 1 through 7, 27 through 34, and 36 through 43 under 35 U.S.C. § 103(a) as being unpatentable over Walton in view of Nakamura as evidenced by Martinot-Lagarde (Answer 2-6; Br. 6). 1 The Examiner has withdrawn claims 9 through 26 from consideration under 37 C.F.R. § 1.142(b) and objected to claims 8, 35, and 44 as drawn to allowable subject but dependent on a rejected claim. 2 Appeal 2006-3072 Application 10/419,763 Appellants argue the claims as a group as well as group claims 2 and 37 separately (Br. 7, 9, 11, and 12). Thus, we decide this appeal based on claims 1 and 2 as representative of Appellants’ groupings of claims. 37 C.F.R. § 41.37(c)(1)(vii) (2005). The Examiner contends Walton teaches all of the claim elements, including an aligned polymerized mesogenic material as a surface layer 14 on at least a part of the inner surface of each of the first and second cell walls, except the element “that the anchoring energy or other properties at the first interface is different from the anchoring energy or other properties at the second interface” (Answer 3-4, citing Walton col. 8, ll. 50-56, and Fig. 5A). The Examiner contends Nakamura teaches a device in “which surface layers are in contact with the liquid crystal [material] at first and second interfaces respectively” (id. 4, citing Nakamura col. 14, ll. 27-40). The Examiner contends “Nakamura teaches that in order to suppress the occurrence of alignment defects to a practically negligible level, the surface energies of the first and second surface layers are different through appropriate designing of the alignment control layers of the substrates” (id., citing Nakamura col. 13, ll. 13-18). The Examiner contends Martinot-Lagarde evinces “[c]hanging the surface energy changes the anchoring energy at the interface” (id. 4-5, citing Martinot-Lagarde col. 1, ll. 25-40). The Examiner concludes it would have been obvious to one of ordinary skill in this art “to have designed the first and second surface layers of Walton with different surface energies, and hence different anchoring energies, in order to obtain a liquid crystal device with minimal alignment defects, as taught by Nakamura, and as evidenced by Martinot-Lagarde” 3 Appeal 2006-3072 Application 10/419,763 (id. 5). With respect to claim 2, the Examiner contends the claim is a product-by-process claim and the claimed product is taught by the references (id. 5-6). Appellants contend modifying Walton’s “device so that the anchoring energies at the two interfaces differ” is contrary to Walton’s objective of “a controlled degree of tilted-off homeotropic alignment . . . [achieved] by using identical alignments on both surfaces, each providing the same tilted- off alignment . . . because the anchoring energies on both surfaces are the same” (Br. 7-9, citing Walton col. 2, ll. 29-50, col. 7, ll. 58-60, col. 8, ll. 44-45, col. 10, ll. 9-39 and Figs. 5A-C, 7, and 8; see also Br. 10). In this respect, Appellants point out Walton states “the ‘pre-tilt produces a single favored direction for tilting of the liquid crystal molecules when a voltage is applied across the liquid crystal layer 16’” (Br. 9, citing Walton col. 10, ll. 9-11). Appellants contend Walton would not have been combined with Nakamura because neither reference discloses how to modify Walton so that polymeric liquid crystal alignment layers 14 of Fig. 5A-C have different anchoring energies, that is, there is no enabling disclosure in the references “how different interfaces between a liquid crystal layer and a polymerized mesogenic material can have different anchoring energies” (id. 10-11). In this respect, Appellants contend Walton’s opposed layers 14 “are made in the same way” and there is “no disclosure of how to make the layers 14 on opposite sides of the cell different from each other” or to make the anchoring energies of the two opposed layers differ (id. 10). Appellants contend “Nakamura is not concerned with polymerized aligned mesogenic materials” 4 Appeal 2006-3072 Application 10/419,763 because “alignment film 13a is made of a polyimide or aromatic polyamide subjected to a uniaxial aligning treatment, such as rubbing” and “alignment film 13b is made of a saline coupling agent, polyimide, polysiloxane, etc., not subjected to a uniaxial alignment treatment” (id., citing Nakamura col. 14, ll. 30-36). Appellants contend the references do not show that Nakamura’s arrangement to reduce alignment defects with alignment films used in layers 13a,13b would be applicable to Walton’s polymerized mesogenic material of surface layers 14 (id. 11-12, citing Nakamura col. 14, ll. 30-36). With respect to claim 2, Appellants contend the references do not disclose how to arrive at different mesogenic material having different anchoring energies, including polymerization at different temperatures (id. 12). The Examiner responds Walton “teaches that a true homeotropic alignment, which is a vertical alignment, as shown by Figs. 7A and 7B, may give rise to regions of different tilt directions, whereby all the different tilt directions cause optical scattering effects,” and “that it is better to provide a slightly off-homeotropic alignment, with a built-in pre-tile which produces a single favored direction for tilting,” thus reducing "the number of defects or distortions in the liquid crystal alignment” (Answer 6-7, citing Walton col. 10, ll. 1-11). The Examiner contends “Walton’s ultimate objective is to minimize the number of defects in the liquid crystal alignment, not to achieve identical alignments and therefore identical anchoring energies of the opposing mesogen alignment layers” (id. 7). The Examiner contends “Nakamura changes the anchoring energy at the interface” thus, teaching “that the alignment defects are minimized to a practically negligible 5 Appeal 2006-3072 Application 10/419,763 level . . . providing the motivation to use it to modify Walton” whose “ultimate objective is to minimize the number of defects in the liquid crystal alignment,” thus addressing “the common problem of providing a defect- free alignment of liquid crystal” (id. 7-8, citing Nakamura col. 13, ll. 13-18). The Examiner contends “Walton teaches that the mesogenic alignment layer is formed from a mixture of first and second polymerizable liquid crystal monomers,” and Nakamura teaches the “concept of suppressing the occurrence of alignment defects . . . through appropriate design of the alignment control layers of the substrates” including its anchoring energy, thus enabling one of ordinary skill in this art to arrive at the claimed invention (id. 8-9 and 9-10, citing Walton col. 5, ll. 1-6, and Nakamura col. 13, ll. 13-18, and col. 5, ll. 38-45). With respect to claim 2, the Examiner contends different polymerizable liquid crystals have different polymerization temperatures (id. 11). In the Reply Brief, Appellants contend one of ordinary skill in this art would not have modified Walton in light of the teachings of Nakamura because Walton and Nakamura differ in the type of liquid crystal devices with respect to liquid crystal materials, alignment layers, mechanisms and defects, and on this basis, respond to specific findings of the Examiner in the Answer (Reply Br. 2-6). Appellants point out Walton discloses “near- homeotropic alignment of liquid crystal devices” generally containing nematic liquid crystal materials while Nakamura discloses “homogeneous alignment” 2 devices containing chiral smectic liquid crystal materials which 2 Appellants disclose the principal alignments “homeotropic,” where the molecules are “substantially perpendicular to the plane of the cell walls,” 6 Appeal 2006-3072 Application 10/419,763 form a “bookshelf” structure (Reply Br. 2). Appellants contend the defects in orientation of the liquid crystal materials in Walton’s devices occur when a field is applied while the defects in Nakamura’s devices occur “primarily during formation of the cell, not during application of a field” (id. 3-4). Appellants contend Walton “solves the field induced defect problem . . . with identical [alignment layer] surfaces” while “Nakamura indicates that when the difference between the surface energies is small, the static defect problem is not solved” (id. 4-5 (original emphasis omitted), citing Nakamura col. 5, ll. 38-45, and Examples 1, 4, and 6). The issue in this appeal is whether the Examiner has carried the burden of establishing a prima facie case of obviousness over the combined teachings of Walton, Nakamura, and Martinot-Lagarde. The plain language of independent claim 1 specifies a liquid crystal device comprising at least, inter alia, any part of the inner surface of each of the first and second cell walls, however small, including at least a surface layer, however small, formed from any manner and amount of polymerized aligned mesogenic material, that can be different on each wall, which is in contact with, that is, interfaces with, to any extent a layer of any manner of liquid crystal material, wherein the anchoring energies of the two interfaces differ to any extent, however small. In claim 2, the differences in anchoring energies is specified to result from polymerization of the mesogenic materials, which can be different, at different temperatures. The open-ended terms “comprising” and “including” open claim 1 to include any manner of and “planar,” where the molecules are “inclined substantially parallel to the plane of the cell walls” (Specification 1:29-2:1). 7 Appeal 2006-3072 Application 10/419,763 additional materials and layers. See, e.g., Exxon Chem. Pats., Inc. v. Lubrizol Corp., 64 F.3d 1553, 1555, 35 USPQ2d 1801, 1802 (Fed. Cir. 1995) (“The claimed composition is defined as comprising - meaning containing at least - five specific ingredients.”); In re Baxter, 656 F.2d 679, 686-87, 210 USPQ 795, 802-03 (CCPA 1981) (“As long as one of the monomers in the reaction is propylene, any other monomer may be present, because the term ‘comprises’ permits the inclusion of other steps, elements, or materials.”); In re Bertsch, 132 F.2d 1014, 1019, 56 USPQ 379, 384 (CCPA 1942) (“it is true that the word ‘comprising’ is usually in patent law held to be synonymous with the word ‘including’”); cf. Ex parte Davis, 80 USPQ 448, 449 (Bd. App. 1948) (“the word ‘comprising’ alone being synonymous with ‘including’”). There is no requirement in claim 1 that the difference in anchoring energies is due to the polymerized aligned mesogenic material (see Br. 7) as there is in dependent claim 2, wherein the differences in anchoring energies is specified to result from polymerization of the mesogenic materials at different temperatures. Thus, claim 2 is framed in product-by-process format. See, e.g., In re Thorpe, 777 F.2d 695, 697, 227 USPQ 964, 966 (Fed. Cir. 1985). There is also no requirement in these claims with respect to the affect of the anchoring energies of the surfaces of the cell walls on the alignment of the liquid crystal material. We note here that independent claim 27 encompasses the same subject matter in this respect as claim 1 while in independent claims 36 and 38, the polymerized mesogenic material causes the difference in anchoring energies, and claim 38 further specifies the polymerized mesogenic material has 8 Appeal 2006-3072 Application 10/419,763 different properties (see Br. 7). These claims also do not require the anchoring energies of the surfaces of the cell walls to affect the alignment of the liquid crystal material to any particular extent. We find that Walton would have disclosed to one of ordinary skill in this art a liquid crystal device in which the degree of tilted-off homeotropic alignment of the liquid crystal material is controlled by at least one polymerized mesogenic material alignment layer in contact with the liquid crystal material (Walton, e.g., col. 2, ll. 49-67; col. 3, l. 66, to col. 4, l. 3; col. 4, ll. 14-17 and 29-65; col. 5, ll. 25-34; col. 11, ll. 36-67; and col. 11, l. 21, to col. 12, l. 12). By way of background, Walton acknowledges “[i]t is very well known to provide a rubbed alignment layer to control the alignment and pretilt angle of adjacent liquid crystal molecules,” which “requires the use of specific combinations of the liquid crystal layer and alignment layer,” as well as methods “which do not require rubbing of the alignment layer” (id. col. 1, l. 19, to col. 2, l. 46). The “titled-off” homeotropic alignment generally has “a slight tilt (typically 1-10°) away from the homeotropic (90°) alignment” (id. col. 2, ll. 29-31; see also col. 11, ll. 21-35). Walton teaches the use of at least one tilted-off homeotropic alignment layer formed from a mixture of first and second mesogenic materials that have at least one polymerizable function group, wherein (1) the number of polymerizable functional groups of the second mesogenic material is less that that of the first mesogenic material, and (2) the ratio of the first and second materials in the mixture is selected to provide a pre- determined pretilt angle to liquid crystal molecules in the liquid crystal layer (Walton, e.g., col. 2, ll. 55-67; col. 3, ll. 1-9; col. 3, l. 56, to col. 4, l. 3; and 9 Appeal 2006-3072 Application 10/419,763 col. 4, l. 66, to col. 5, l. 19). We find this disclosure would have suggested to one of ordinary skill in this art that the layer on the opposite side of the liquid crystal layer can be an alignment layer formed from the same or different mesogenic materials as the first alignment layer, from any other alignment material, and from combinations thereof (id., e.g., col. 4, ll. 37-65; col. 6, ll. 37-42; col. 8, ll. 49-56; Example 1; and Figs. 1 and 5).3 The polymerized mesogenic material in the first alignment layer and the material in the opposed or second alignment layer can be formed on “a pre- formed alignment layer such as a rubbed polyimide layer,” illustrated by the liquid crystal cell in Figs. 1 and 5 wherein polymeric liquid crystal alignment layers 14 overlay polyimide alignment layers 12 (id., e.g., col. 5, ll. 20-24; col. 6, ll. 37-42; col. 8, ll. 49-56; col. 10, l. 45, to col. 11, l. 5; and Example 3). Walton’s Examples 1-4 illustrate liquid crystal cells in which the polymeric liquid crystal alignment layers 14 are formed from the same mixture of polymeric mesogenic material and interface with a nematic liquid crystal mixture, wherein each of the four mixtures tested provide different pretilt angle measured in degrees (Walton, cols 6-8 and table at col. 7, ll. 24-30). Walton’s Example 5 illustrates the defect occurring where “the liquid crystal molecules tilt in different directions” upon application of an 3 It is well settled that a reference stands for all of the specific teachings thereof as well as the inferences one of ordinary skill in this art would have reasonably been expected to draw therefrom, see In re Fritch, 972 F.2d 1260, 1264-65, 23 USPQ2d 1780, 1782-83 (Fed. Cir. 1992); In re Preda, 401 F.2d 825, 826, 159 USPQ 342, 344 (CCPA 1968), presuming skill on the part of this person. In re Sovish, 769 F.2d 738, 743, 226 USPQ 771, 774 (Fed. Cir. 1985). 10 Appeal 2006-3072 Application 10/419,763 applied field that is overcome “by an alignment layer of the present invention which produces a small surface pre-tilt away from 90°” resulting in “a single favoured [sic] direction for tilting . . . when a voltage is applied” (id. col. 9, l. 51, to col. 10, l. 11, and Figs. 7A-B). We find Nakamura would have acknowledged chiral smectic liquid crystal devices have problems arising from the liquid crystal molecules forming two types of chevron-shaped layer structures between the liquid crystal cell walls which have been addressed by providing a pretilt angle to uniformly direct the chevron layer structure in one direction, and by converting “a bent chevron structure into a bookshelf layer structure wherein smectic layers are aligned with little inclination from those perpendicular to the” cell walls (Nakamura col. 1, l. 53, to col. 2, l. 49). Nakamura further acknowledges with respect to liquid crystal materials providing a bookshelf structure or a structure close thereto, that “[g]enerally, . . . these liquid crystal materials including a mesomorphic compound having a perfluoroether terminal chain do not assume cholesteric phase and it is difficult to finally produce a sufficiently good alignment state” (id. col. 2, ll. 59-63). Nakamura would have disclosed to one of ordinary skill in this art that this problem can be addressed in a liquid crystal device in which the liquid crystal layer is a mesomorphic compound with perfluoroether terminal chains that lacks a cholesteric phase and stably assumes “a bookshelf structure or structure close thereto,” when the liquid crystal layer is contacted on opposite sides by substrates having different surface energies (Nakamura, e.g., col. 2, l. 66, to col. 3, l. 30, col. 3, ll. 36-65, col. 4, l. 33, to 11 Appeal 2006-3072 Application 10/419,763 col. 5, l. 34, and col. 6, l. 16, to col. 9, l. 37). The surface of the first substrate can comprise, inter alia, a polyimide or aromatic polyamide film selectively subjected to a uniaxial aligning treatment as an alignment control layer, and the second substrate can comprise, inter alia, a polyimide not subjected to uniaxial alignment, a silane coupling agent, or a fluorine- containing resin as alignment control layer, wherein the surface energy of the first alignment control layer is greater than the surface energy of the second alignment control layer (id., e.g., col. 3, ll. 19-22; col. 5, ll. 35-43; col. 9, l. 38, to col. 13, l. 36; col. 14, ll. 27-54; col. 14, l. 66, to col. 15, l. 10; Fig. 1; and Example 1). We find Nakamura teaches that in this arrangement of elements, the alignment defects encountered with the perfluoroether terminal chain containing liquid crystal material can be suppressed to a negligible level and a uniform, homogeneous alignment if, in addition to difference in the surface energies of the first and second alignment control layers on the respective opposed cell walls, the surface energy of an ordinary perfluoroether terminal chain containing liquid crystal material is less than the surface energy of an alignment control film (id., e.g., col. 5, l. 35, to col. 6, l. 4; col. 13, ll. 12-33; and Example 1). Nakamura further teaches that if the surface energy of an ordinary perfluoroether terminal chain containing liquid crystal material is greater than the surface energy of an alignment control film a homeotropic alignment develops, and that the surface energy of perfluoroether terminal chain containing liquid crystal material is less than that of a fluorine-free liquid crystal material (id., e.g., col. 13, ll. 26-29). We find Martinot-Lagarde would have acknowledged “[i]t is well known to the person skilled in the art that molecules of nematic phases 12 Appeal 2006-3072 Application 10/419,763 (‘nematics’) and liquid crystals in general, on coming into contact with a boundary surface, orient themselves in one or more directions because of their interaction with the substrate” (Martinot-Lagarde col. 1, ll. 7-11). The reference further acknowledges the additional surface energy resulting from applying an external field to the surface of the substrate reorients the liquid crystal molecules and is termed the anchoring energy (id. col. 1, ll. 11-38; see Br. 11). We determine the combined teachings of Walton, Nakamura, and Martinot-Lagarde, the scope of which we determined above, provide convincing evidence supporting the Examiner’s case that the claimed invention encompassed by claims 1 and 2, as we interpreted these claims above, would have been prima facie obvious to one of ordinary skill in the liquid crystal device arts familiar with the interaction at the interface between alignment layers on cell wall surfaces and the liquid crystal layer therebetween in liquid crystal cells of liquid crystal devices. Indeed, on this record and in light of the advanced contentions, the acknowledgements and teachings of the combined references establish that one of ordinary skill in the art had knowledge of the affect of the interaction at the interface between the alignment layers and the liquid crystal layer on the orientation of the liquid crystal molecules relative to the liquid crystal cell walls, with and without an applied field. This interaction is described by Nakamura and Martinot-Lagarde in terms of surface energies of the alignment layers and the liquid crystal layer, with Martinot-Lagarde referring to the additional surface energy provided by an applied field as anchoring energy. 13 Appeal 2006-3072 Application 10/419,763 Thus, we determine, as does the Examiner, that this person would have adjusted the surface energies and thus, the anchoring energies of the interfacing alignment layers on the liquid crystal cell walls relative to the liquid crystal layer to obtain and maintain the desired alignment of the liquid crystal layer relative to the cell walls, with and without an applied field. Indeed, Nakamura teaches that interfacing alignment layers with different surface energies are used for this purpose with particular liquid crystal material. Walton also discloses that interfacing alignment layers are used for this purpose for any manner of liquid crystal material. In this respect, Walton teaches at least one interfacing alignment layer on one cell wall is formed by polymerizing a mixture of two different polymerizable mesogenic materials in a ratio selected to provide a predetermined alignment of the liquid crystal molecules in the liquid crystal layer, and an interfacing alignment layer on the other cell wall can be formed from the same polymerizable mixture or from any other material which is taught therein or known to form an interfacing alignment layer. Indeed, contrary to Appellants’ contentions, the fact that Walton’s Examples 1-4 illustrate liquid crystal cells wherein the interface alignment layers on the cell walls are the same does not limit the teachings in the reference thereto in disregard of the clear teachings therein that interfacing alignment layers can be different as long as one is formed from the specified polymerizable mixture. See, e.g., In re Lamberti, 545 F.2d 747, 750, 192 USPQ 278, 280 (CCPA 1976) (“[T]he fact that a specific [embodiment] is taught to be preferred is not controlling, 14 Appeal 2006-3072 Application 10/419,763 since all disclosures of the prior art, including unpreferred embodiments, must be considered.”). Thus, we determine that one of ordinary skill in this art routinely following the teachings of Walton would have formed the interface alignment layer on the second cell wall from the same or different polymerizable mixture of polymerizable mesogenic material than that used for the interface alignment layer on the first cell wall. In doing so, this person would have arrived at an interface alignment layer of polymerized aligned mesogenic material on the second cell wall that is different from that of the first wall with respect to properties thereof, including surface energy and thus anchoring energy, which affect the pretilt angle of the liquid crystal layer of the liquid crystal cell. Indeed, we determine that even where each of the interface alignment layers of the cell walls is formed by polymerizing separate batches of the same mixture of polymerizable mesogenic materials, one of ordinary skill in this art would have reasonably expected the resulting polymeric aligned mesogenic materials to be different to some extent, and thus the properties thereof to differ to that extent. Accordingly, one of ordinary skill in this art routinely following the combined teachings of Walton, Nakamura, and Martinot-Lagarde would have reasonably arrived at the claimed liquid crystal device encompassed by claims 1 and 2, including all of the limitations thereof arranged as required therein, without recourse to Appellants’ Specification. We are not persuaded otherwise by Appellants’ contentions. One of ordinary skill in this art would have considered the combined acknowledgments and teachings of the applied references in light of the knowledge in the liquid 15 Appeal 2006-3072 Application 10/419,763 crystal device art and thus, would have recognized that the different interface alignment layers on each of the cell walls taught by Walton would result in layers with different surface energies and anchoring energies, even though as Appellants point out, the materials, structure and mechanisms of the liquid crystal devices of Walton and Nakamura are different. See In re Keller, 642 F.2d 413, 425, 208 USPQ 871, 881 (CCPA 1981) (“The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.”). Indeed, one of ordinary skill in this art routinely following Walton would have reasonably arrived at different polymerized aligned mesogenic materials as interface alignment layers on the liquid crystal cell walls even if this person would not have recognized that different surface energies and thus, anchoring energies, would result. In this respect, it is well settled that Appellants’ discovery of a new property of a product or elucidation of the mechanism by which that product functions does not render the old product again patentable simply because those practicing the product may not have appreciated the property or the mechanism. See, e.g., In re Spada, 911 F.2d 705, 707, 15 USPQ2d 1655, 1657 (Fed. Cir. 1990); In re Woodruff, 919 F.2d 1575, 1578, 16 USPQ2d 1934, 1936 (Fed. Cir. 1990); Titanium Metals Corp. v. Banner, 778 F.2d 775, 782-83, 227 USPQ 773, 779 (Fed. Cir. 1985); W.L. Gore & Assocs. v. Garlock, Inc., 721 F.2d 1540, 1548, 220 USPQ 303, 309 (Fed. Cir. 1983) (“[I]t is . . . irrelevant that those using the invention may not have appreciated the results[,] . . . [otherwise] it would 16 Appeal 2006-3072 Application 10/419,763 be possible to obtain a patent for an old and unchanged process. [Citations omitted.]”); In re Skoner, 517 F.2d 947, 950-51, 186 USPQ 80, 82-83 (CCPA 1975) (“Appellants have chosen to describe their invention in terms of certain physical characteristics . . . . Merely choosing to describe their invention in this manner does not render patentable their method which is clearly obvious in view of [the reference].” (citation omitted)). Accordingly, based on our consideration of the totality of the record before us, we have weighed the evidence of obviousness found in the combined teachings of Walton, Nakamura, and Martinot-Lagarde with Appellants’ countervailing evidence of and argument for nonobviousness, and conclude that the claimed invention encompassed by appealed claims 1 through 7, 27 through 34, and 36 through 43 would have been obvious as a matter of law under 35 U.S.C. § 103(a). The Primary Examiner’s decision is affirmed. OTHER ISSUES In view of our affirmance of the decision of the Primary Examiner, we decline to exercise our authority under 37 C.F.R. § 41.50(b) (2006) and enter a new ground of rejection of pending claims 8, 35, and 44 (see above note 1) over the combined teachings of Walton, Nakamura, and Martinot-Lagarde, as we considered this combination of references above, leaving it to the Examiner to consider this matter upon any further examination of the pending claims in this Application upon disposition of this appeal. 17 Appeal 2006-3072 Application 10/419,763 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) (2006).
