DECISION ON APPEAL Appeal 2011-006311 Application 11/503,596 2 Appellants appeal under 35 U.S.C. § 134 from the Examiner’s decision finally rejecting claims 1 and 4-14 under 35 U.S.C. § 103(a). We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. Appellants claim an intermediate transfer member for use in electrostatography, in particular for the receipt and transfer of electrostatic images. The transfer member is a multi-layered structure comprising, in order from outer to inner layers: a release layer, a compliant layer, an outer conductive layer, an insulating support layer, and a second conductive layer. At least one conductive connection is provided between the inner side of the insulating support layer and the outer conductive layer, thereby providing a conductive connection between the outer conductive layer and the second conductive layer (Claim 1). Representative claim 1 reads as follows: 1. An intermediate transfer member for use in an electrostatographic machine, comprising: an insulating support layer having an inner side and outer side; a conductive outer layer disposed on the outer side of said insulating layer; at least one conductive connection between the inner side of the insulating support layer and the conductive outer layer; a second conductive layer disposed on the inner side of said insulating support layer; a compliant layer disposed on the conductive outer layer; and Appeal 2011-006311 Application 11/503,596 3 a release layer disposed on said compliant layer. The prior art listed below is relied upon by the Examiner as evidence of obviousness: Schlueter 6,245,402 B1 Jun. 12, 2001 Appellants’ admitted prior art, Specification, “BACKGROUND OF THE INVENTION” section, particularly pages 3-5 (hereafter “APA”). Under 35 U.S.C. § 103(a), the Examiner rejects claims 1 and 4-14 as unpatentable over APA in view of Schlueter. We will sustain this rejection for the reasons expressed in the Answer with the comments below added for emphasis. Appellants do not separately argue any of the claims on appeal (Br. 2- 7). For purposes of this appeal, we select claim 1 to decide the issues raised by this rejection. See 37 C.F.R. § 41.37(c)(1)(vii) (“When multiple claims subject to the same ground of rejection are argued as a group by appellant, the Board may select a single claim from the group of claims that are argued together to decide the appeal with respect to the group of claims as to the ground of rejection on the basis of the selected claim alone.”). The Examiner found that the APA teaches an intermediate transfer member comprising a multi-layered structure as recited in claim 1, lacking only a conductive connection between the inner side of the insulating support layer and the conductive outer layer (Ans. 3). Appellants acknowledge, but do not contest, this finding (App. Br. 2; Rep. Br. 2). We note that the APA teaches that the intermediate transfer member may be a seamed belt whose ends may be joined by adhesive bonding (see APA, pg. Appeal 2011-006311 Application 11/503,596 4 3, ll. 13-16). The Examiner states that Schlueter teaches an intermediate transfer belt for electrophotographic machines, with a mechanically and electrically invisible seam formed by joining two ends of the belt at the seam utilizing an electrically conductive adhesive (Ans. 3). The adhesive joining the belt ends provides a conductive connection from the inner side of the support layer to the conductive outer layer (Ans. 4). The Examiner concluded that it would have been obvious to one having ordinary skill in the art at the time of the invention to connect the ends of the APA’s intermediate transfer member with a conductive adhesive to provide a mechanically and electrically invisible seam as taught by Schlueter, wherein the conductive adhesive in the invisible seam electrically connects one side of the support layer to the other in the APA intermediate transfer structure , given the predictable results and reasonable expectation of success (id.). Appellants argue that the APA requires an external electrical contact be made from a high voltage source directly to the outer conductive layer in order to establish the electrostatic transfer field (App. Br. 3). As such, Appellants state that the APA fails to teach “providing any electrical current flow through or transfer field across the insulating support layer” (App. Br. 3, emphasis omitted). Appellants then argue that Schlueter in contrast provides an electrical field across the entire transfer member, by substantially matching the electrical properties of the transfer member substrate to those of the adhesive in the seam (id.). Appellants conclude that this difference is significant as, in their view, Schlueter teaches away from the Examiner’s proposed combination since the APA has an insulating support layer which is not conductive (App. Br. 4; Rep. Br. 2). Thus, while the combination of Schlueter with the APA would produce the claimed Appeal 2011-006311 Application 11/503,596 5 invention, Appellants assert that one would not have employed Schlueter’s seam adhesive in the APA’s intermediate transfer member given Schlueter’s teaching that the electrical properties of the seam and substrate should match (Rep. Br. 2). Assertions of “teaching away” are evaluated by determining whether the prior art directly warns against the claimed invention or teaches that the claimed invention would not work, e.g. Ricoh Co., Ltd. v. Quanta Computer Inc., 550 F.3d 1325, 1332 (Fed. Cir. 2008) (“A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.”) (internal quotation omitted); Baxter Int’l, Inc. v. McGaw, Inc., 149 F.3d 1321, 1328 (Fed. Cir. 1998) (finding no teaching away where nothing in the prior art device suggested that the claimed invention was unlikely to work); In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994) (“A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.”). We have evaluated this argument and find it unpersuasive. Neither the APA nor Schlueter would have led an inventor down an errant path or discourage using the combination. Initially, as noted by the Examiner, Schlueter does indeed account for the possibility that the seam adhesive’s electrical properties poorly match those of the substrate (Ans. 6; Schlueter, col. 11, ll. 31-33, 50-53; col. 21, ll. 57-60; col. 23, ll. 24-61). We note that Schlueter refers to the use of a conductive overcoat over the insulating Appeal 2011-006311 Application 11/503,596 6 substrate to thereby electrically match the conductive adhesive seam. As the APA already has a conductive outer layer, common sense would indicate that there is no need to add such an overcoat. In other words, based on Schlueter’s teaching, one of ordinary skill in the art would have recognized that the APA’s intermediate transfer belt would merely require use of Schlueter’s conductive adhesive in the seam ensuring that the electrical properties in the seam match that of the belt laterally spaced from the seam. Thus, far from teaching away, Schlueter directs the solution of how to connect the ends of the APA belt together in a manner that produces a seam that is mechanically and electrically invisible. Appellants further argue that Schlueter, column 23, “does not teach use of a conductive overcoat specifically with an insulating support” (App. Br. 4,). Indeed, Schlueter does teach, under certain circumstances, that the resistivity of the overcoat may be near 1012 ohm-cm (Schlueter, col. 23, ll. 54-55). However, contrary to Appellants’ argument, Schlueter does teach an embodiment with “a relatively insulating substrate and a relatively conducting adhesive” (id., ll. 24-25). It is for this embodiment that Schlueter suggests the use of an overcoat to “’hide’ the effects of the highly mismatched adhesive and substrate electrical properties (id., ll. 41-43). Schlueter also teaches in this same paragraph that factors such as a low resistivity overcoat can reduce the required overcoat thickness (id., ll. 55- 57). As set forth above, we find that one of ordinary skill in the art would have recognized that the conductive outer layer of the APA’s intermediate transfer member would closely match the conductive seam adhesive thereby achieving Schlueter’s purpose of creating an electrically invisible seam. Appeal 2011-006311 Application 11/503,596 7 Appellants further argue that the present invention solves a different problem for a different system than that taught by Schlueter (App. Br. 5). Appellants state that “[s]uch failure to solve the problem actually addressed by [Appellants] by actually following the preferred teachings of the applied references is strong evidence of the non-obviousness of the present claimed invention” (App. Br. 6, emphasis omitted). In this case, the problem Appellants’ invention solves is “the need to have an external electrical contact to the conductive outer layer as required in the ‘admitted prior art’ . . . facilitating and simplifying the belt construction and HV [(high voltage)] connection design” (App. Br. 5). Appellants’ solution to this problem is “having both an inner and outer conductive layer, and methods for electrically connecting these two conductive layers employing a conductive, low electrical resistance path . . . utilizing a conductive material” (id.). We do not find this argument persuasive. The Supreme Court in KSR Int’l. Co. v. Teleflex Inc., 550 U.S. 398, 419-420 (2007) stated that: In determining whether the subject matter of a patent claim is obvious, neither the particular motivation nor the avowed purpose of the patentee controls. . . . The first error of the Court of Appeals in this case was . . . by holding that courts and patent examiners should look only to the problem the patentee was trying to solve. The Supreme Court explained that “[u]nder the correct analysis, any need or problem known in the field of endeavor at the time of [the] invention and addressed by the patent can provide a reason for combining the elements in the manner claimed.” KSR Int'l. Co., 550 U.S. at 420. In other words, a prior art reference solution may be considered by one of ordinary skill in the art to establish obviousness under 35 U.S.C. § 103(a) if it is reasonably Appeal 2011-006311 Application 11/503,596 8 pertinent to any problem with which one of ordinary skill in the art is concerned. This broadened test suggested by KSR is consistent with the language of 35 U.S.C. § 103 which requires us to focus on one of ordinary skill in the art, rather than the subjective reason given by inventors in the Specification, in evaluating the content of the prior art to determine the propriety of obviousness. While any advantages or problem solving intended by inventors as described in the Specification may be considered as relevant secondary evidence, they are not controlling in terms of evaluating the contents of the prior art references for the purpose of determining appropriateness of their combinability. Graham v. John Deere Co., 383 U.S. 1, 17-18 (1966). Here, the APA already contains part of the solution proposed by Appellants, that being the inner and outer conductive layers of the intermediate transfer member. Schlueter is addressing the problem of how to join the ends of an intermediate transfer member with an electrically invisible seam. One of ordinary skill in the art would have recognized that this problem would be in common with the APA’s intermediate transfer member when joining its ends. Schlueter’s solution, using a conductive adhesive to join the ends, would solve this problem. As indicated by Appellants, the combination of the APA with Schlueter produces the invention (Rep. Br. 2). As Schlueter identifies both a problem in common with the APA and a solution to that problem, we agree with the Examiner that the ordinarily skilled artisan would have found the use of the solution of joining the ends of the APA with conductive adhesive to have been obvious. Finally, we have considered Appellants’ argument that the Examiner has employed “impermissible hindsight reconstruction of the claimed Appeal 2011-006311 Application 11/503,596 9 invention based on [Appellants’] own teachings and selected portions of the cited art for which there is no teaching or suggestion to combine (and rather, teachings away based on the actual teachings of such references as explained above)” (App. Br. 6, emphasis omitted). This argument is not persuasive for the reasons set forth above and our comments below. An Examiner avoids the application of impermissible hindsight by supplying the requisite factual basis and convincing line of reasoning to support the obviousness conclusion. See KSR Int’l. Co., 550 U.S. at 421 (noting that the fact finder must be aware “of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning.”); In re Warner, 379 F.2d 1011, 1017 (CCPA 1967). To support a conclusion that a claim is directed to obvious subject matter, an Examiner must present a “convincing line of reasoning” as to why one of ordinary skill in the art would have found the claimed invention to have been obvious. Ex parte Clapp, 227 USPQ 972, 973 (BPAI 1985); see also, In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[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.”), quoted with approval in KSR, 550 U.S. at 418. In the record before us, it is clear that the Examiner has complied with both requirements for supporting the obviousness conclusion. The Examiner supplied the requisite factual basis for this conclusion by citing to the APA which taught every element of claim 1 except for a conductive connection between the inner side of the insulating support layer and the outer conductive layer, and Schlueter which taught the use of a conductive Appeal 2011-006311 Application 11/503,596 10 adhesive to join the ends of an intermediate transfer member together to ensure that the seam is electrically invisible (Ans. 3). Further, the Examiner articulated the rationale underpinning the conclusion, indicating that one of ordinary skill in the art would have joined the ends of the APA’s intermediate transfer member together with a conductive adhesive as taught by Schlueter to provide a mechanically and electrically invisible seam (Ans. 4). We find no error in either aspect of this rejection. Accordingly, we sustain the Examiner’s rejection as to appealed claims 1 and 4-14. Conclusion The decision of the Examiner is affirmed. 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). AFFIRMED ssl Copy with citationCopy as parenthetical citation
