BROWN, and MICHAEL L. HOELTER, Administrative Patent Judges. BROWN, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellant1 seeks review under 35 U.S.C. § 134(a) of the Examiner’s decision rejecting claims 1, 5, 8, and 10.2 Appellant’s representative presented oral argument on March 15, 2021. We have jurisdiction under 35 U.S.C. § 6(b). We REVERSE. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies Max Co., Ltd., as the real party in interest. Appeal Br. 3. 2 Claims 2–4, 6, 7, and 9 are cancelled. Appeal Br. (Claims App.). Appeal 2020-005919 Application 15/272,778 2 CLAIMS Claim 1 is independent. Claims 5, 8, and 10 depend from claim 1. Claim 1 is illustrative and is reproduced below. 1. A stapler configured to bind a workpiece using a staple made of a non-metal soft material, the staple having a crown portion and a pair of leg portions formed by bending both longitudinal ends of the crown portion toward one direction, the stapler comprising: a placing base on which the workpiece is placed, the placing base including a placing surface; a penetrating part that includes a pair of cutting blades spaced apart from each other according to a length of the crown portion of the staple, causes the cutting blades to penetrate from one surface of the workpiece placed on the placing base to another surface thereof, and forms a hole in the workpiece, wherein the other surface is on an opposite side of the workpiece than the one surface; an opening that is provided on the placing base so that the pair of cutting blades and the pair of leg portions of the staple inserted into the workpiece pass through the opening; and a pressing portion that is provided in the opening of the placing base and suppresses deformation of the workpiece caused by a force applied to the workpiece from the cutting blades when the cutting blades penetrate the workpiece[,] wherein the pressing portion includes a pressing surface facing the other surface of the workpiece placed on the placing base and the pressing surface is on a same plane as the placing surface of the placing base when the cutting blades penetrate the workpiece, and the stapler includes a cutting blade guide that suppresses the pair of cutting blades penetrating the workpiece from moving inwardly, and the pressing portion is provided on the cutting blade guide, wherein the stapler includes a driving member that causes the cutting blade guide to retract from a position between the cutting blades after the cutting blades penetrate the workpiece to a retracted position, Appeal 2020-005919 Application 15/272,778 3 wherein the other surface of the workpiece placed on the placing base is supported, between positions at which the pair of cutting blades penetrate through the workpiece, by the pressing portion, wherein the opening includes a first portion in which the pressing portion is located when the cutting blades penetrate the workpiece, and the opening further includes a second portion at which the pressing portion is located when the cutting blade guide is in the retracted position, the pressing portion is configured to move through the opening between the first portion and the second portion of the opening as the cutting blade guide is moved from the position between the cutting blades and the retracted position, and wherein the pressing surface of the pressing portion has a height on the same plane as the placing surface of the placing base such that the pressing portion abuts against and supports the workpiece at the first portion of the opening and during movement between the first portion and the second portion of the opening. Appeal Br. 45–47 (Claims App.). REJECTION Claims 1, 5, 8, and 10 are rejected under 35 U.S.C. § 103 as unpatentable over Kato (US 2014/0158738 A1, pub. June 12, 2014) and Elonsson (US 2004/0262363 A1, pub. Dec. 30, 2004).3 ANALYSIS The Examiner finds Kato discloses a stapler 1 comprising, inter alia, placing base 80 on which workpiece P is placed and including a placing 3 The Non-Final Action indicates claims 1 and 4–10 are rejected. Non-Final Act. 2. Appellant notes, however, that claims 4 and 9 have been cancelled. Appeal Br. 3 n1. Appeal 2020-005919 Application 15/272,778 4 surface (upper surface of placing base 80); cutting blades 21; an opening provided on placing base 80 (Fig. 20); a pressing portion (cutting blade guide 23) provided in the opening and including a pressing surface (top portion of cutting blade guide 23) which is “on an essentially same plane as the placing surface of the placing base when the cutting blades penetrate the workpiece”; and a cutting blade guide (cutting blade guide 23) on which the pressing portion is provided. Non-Final Act. 3–4 (citing Cato, Figs. 1, 19, 20, 22). The Examiner also finds that the surface of the workpiece placed on the placing base is supported, between positions at which the cutting blades penetrate through the workpiece, by the pressing portion. Id. at 3 (citing Kato, Figs. 19, 20). The Examiner states “the supporting of the workpiece does not need to be explicitly taught. The prior art is capable of completing the supporting function.” Id. (boldface omitted). The Examiner also finds the opening on the placing base includes a first portion and a second portion, as claimed. Id. at 3–4 (citing Kato, Figs. 14, 53, 60–63, ¶¶ 310–313). The Examiner concedes Kato does not disclose all limitations of the final “wherein” clause of claim 1, which recites: the pressing surface of the pressing portion has a height on the same plane as the placing surface of the placing base, such that the pressing portion abuts against and supports the workpiece at the first portion of the opening and during movement between the first portion and the second portion of the opening. Non-Final Act. 4 (emphasis added). To address this omission of Kato, the Examiner relies on Elonsson as teaching “a support surface [cutting pad 49] on the same exact plane as a placing surface.” Id. (citing Elonsson, Fig. 9). The Examiner concludes that it would have been obvious to one of ordinary skill in the art to modify Kato’s pressing surface “with the pressing surface location of Elonsson by moving the pressing surface of Kato slightly Appeal 2020-005919 Application 15/272,778 5 higher.” Id.; see also Ans. 9 (“Examiner has only considered the location of Elonsson during penetration of the workpiece in the combination stated above.”). The Examiner’s stated motivation for this modification of Kato is “supporting the workpiece during stapling.” Id. Appellant contends the proposed combination of Kato and Elonsson fails to render obvious the claimed stapler. We agree with Appellant for several reasons. First, as discussed above, the Examiner’s position is that: (a) Kato’s pressing surface is “on an essentially same plane as the placing surface of the placing base when the cutting blades penetrate the workpiece”; and (b) Kato’s cutting blade guide 23 “is capable of completing the supporting function,” that is, supporting the workpiece “between positions at which the pair of cutting blades penetrate through the workpiece.” Non-Final Act. 3–4. In response, Appellant explains “Fig. 34B of the present application illustrates an arrangement similar to that described by Kato, in that the top of guide 23 is positioned below the paper placing base 80.” Appeal Br. 20. Figure 34B shows workpiece P being deformed so as to be in contact with a top surface of lower cutting blade guide 23 during cutting. Id. Accordingly, it appears Appellant agrees with the Examiner’s finding (b). Furthermore, Kato discloses that placing base 80 supports workpiece P between these cutting positions. See, e.g., Kato, Fig. 20. The Examiner does not identify any disclosure in Kato, or provide any other evidence in the prior art, that teaches or suggests that the support provided by Kato’s placing base 80 and lower cutting blade guide 23 is insufficient, leaving a skilled artisan with a need to modify Kato to provide additional support of workpiece P between these cutting positions. As such, the reason proffered by the Examiner for Appeal 2020-005919 Application 15/272,778 6 making the proposed modification of Kato is inadequate. That is, the reason proffered by the Examiner, namely, “supporting the workpiece during stapling,” appears to already be adequately met by the present locations of placing base 80 and lower cutting blade guide 23 in Kato. Just because Kato’s “pressing surface” could be moved slightly higher is not, in itself, an adequate reason to make this modification to Kato. Second, Appellant explains that the claimed stapler provides an improvement over Kato’s stapler. Appeal Br. 12. As shown in Figure 19 of Kato, workpiece P is cut by cutting blades 21, and the upper surface of guide member 23 faces workpiece P and is positioned below the upper surface of paper placing base 80 on which workpiece P is placed. Appellant points out that “the top of the guide 23 is clearly below the paper placing base 80, as is apparent from the fact that there is a gap between the guide 23 and the workpiece P.” Id. at 13. As noted by Appellant, Kato discloses, “[a]s illustrated in FIG. 1 and so forth, the cutting blade guide 23 is provided under the paper placing base 80 . . . .” Id. at 12–13 (citing Kato ¶ 179) (boldface omitted). As noted above, the Examiner has equated the upper surface of Kato’s paper placing base 80 to the claimed “placing surface,” and the upper surface of Kato’s guide member 23 to the claimed “pressing surface.” Non-Final Act. 2, 3. Appellant explains it has recognized that, where the pressing portion is recessed below the placing surface of the placing base, as in Kato, deformation of the workpiece can cause the penetration time and forces associated with penetration of the blades through the workpiece to increase, thereby making the operation more difficult and causing poor performance. Appeal Br. 11 (citing Spec. ¶¶ 93–95). Appellant contends Kato does not recognize problems with an arrangement Appeal 2020-005919 Application 15/272,778 7 in which cutting blade guide 23 is provided under paper placing base 80. Id. at 14. Instead, Appellant contends, Kato teaches that cutting blades 21 are tapered to suppress increases in resistance as they penetrate workpiece P, and satisfactory force/load performance is achieved simply by the taper of the cutting blades. Id. at 13–14 (citing Kato ¶¶ 199–200). Appellant explains that, in contrast, in the claimed stapler the pressing portion (23b) is provided as a top surface of the cutting blade guide (23), and the pressing surface (23b) of the pressing portion is on a same plane as the placing surface of the placing base when the cutting blades penetrate the workpiece. Appeal Br. 11–12. Appellant further explains that, also in the claimed arrangement, the height of the pressing portion is on the same plane as the placing surface, so that the pressing portion abuts against and supports the workpiece at the first portion of the opening (when the workpiece is being penetrated by the cutting blades) and also during movement between the first portion and the second portion of the opening. Id. at 12. In contrast, the top of Kato’s cutting blade guide 23 would be under the paper placing base “both when the guide is under or between the cutting blades during a cutting operation, and also when the guide 23 is moved between the projected and retracted positions.” Id. at 15–16. Appellant further explains that Appellant’s Figure 35 illustrates a comparison of an arrangement where the pressing portion is on the same plane as the paper placing base to an arrangement where the pressing portion is not on a same plane as the paper placing base. Appeal Br. 20. Appellant indicates that the latter arrangement is illustrated in Figure 34B and corresponds to Kato’s location of the top of cutting blade guide 23. Id. Appellant points out Figure 35 shows that where the pressing surface of Appeal 2020-005919 Application 15/272,778 8 cutting blade guide 23 is not on the same plane as the paper placing base, a significant spike occurs during penetration of the cutting blades (broken line), whereas when the pressing portion is on the same plane as the paper placing base, the load required during penetration of the cutting blades (solid line) is significantly reduced. Appeal Br. 21 (citing Spec. ¶¶ 108–112). Appellant further submits that, in addition to the increased loads of Kato, the contact length or duration over which such loads are encountered also increases where the pressing surface is not on the same plane as the paper placing surface. Id. (citing Spec. ¶¶ 110–111). Appellant contends Kato fails to both identify the problem Appellant recognized, and recognize that the claimed combination provides a solution to the problem. Appeal Br. 22. Appellant notes “the failure of the prior art to recognize the problem solved by an invention reflects nonobviousness— even if the solution is obvious once the problem is recognized-unless the prior art provides a separate reason to modify the prior art.” Id. at 24 (citing Eibel Process Co. v. Minnesota & Ontario Paper, 261 U.S. 45 (1923); In re Conrad, 759 Fed. Appx. 982, 985 (Fed. Cir. 2019); In re Sponnoble, 405 F.2d 578 (CCPA 1969)). As discussed above, the Examiner has not provided a separate, adequate reason based on rational underpinnings to modify Kato in view of Elonsson to result in the claimed stapler. Thus, we do not sustain the rejection of claim 1, and claims 5, 8, and 10 depending therefrom, as unpatentable over Kato and Elonsson.
