BENNETT, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellants appeal under 35 U.S.C. § 134 from the Examiner’s final rejection of claims 1—17 and 20-23, which are all pending claims. We have jurisdiction under 35 U.S.C. § 6(b). We reverse. 1 Appellants’ Brief (“App. Br.”) identifies Rexnord Industries, LLC as the real party in interest. App. Br. 1. Appeal 2016-001335 Application 13/994,263 CLAIMED SUBJECT MATTER The claims are directed to a gripper attachment. Claim 17 is the only independent claim, and is reproduced below: 17. A gripper chain assembly, comprising: a first chain capable of traveling in a path direction; a first gripper attachment having a first base mounted to the first chain; a first plurality of resilient fingers defining at least one row of individual fingers extending from the first base and substantially aligned transversely to the path direction; and a second chain adjacent the first chain capable of traveling in the path direction; a second gripper attachment having a second base mounted to the second chain; a second plurality of resilient fingers defining at least one row of individual fingers extending from the second base toward the first plurality of resilient fingers, wherein when an article is between the first plurality of resilient fingers and the second plurality of resilient fingers, each of the fingers of the first and second plurality of resilient fingers substantially independently deflect and flex from a natural unengaged position to engage and generally conform to the article. App. Br. A-4 (Appendix A). The prior art relied upon by the Examiner in rejecting the claims on REFERENCES appeal is: Bavelloni Hodlewsky Egger US 4,537,301 Aug. 27, 1985 US 5,219,065 June 15, 1993 US 7,032,737 B2 Apr. 25, 2006 2 Appeal 2016-001335 Application 13/994,263 REJECTIONS Claims 17, 1—16, 20, 21, and 23 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Egger and Bavelloni. Final Act. 2. Claim 22 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Egger, Bavelloni, and Hodlewsky. Final Act. 7. ISSUE Has the Examiner erred in finding a person of ordinary skill in the art would have been motivated to combine Egger and Bavelloni? ANALYSIS The Examiner rejects independent claim 17 as being obvious over the combination of Egger and Bavelloni. Egger relates to “a conveying apparatus for transporting open containers.” Egger, Abstract. The conveying apparatus includes “gripping elements [ ] adapted to grasp and guide the containers, such that additional guiding elements can be avoided.” Id. In setting forth the rejection, the Examiner relies primarily on Egger, finding it teaches most of the limitations of claim 17; however, the Examiner finds that Egger is deficient because although it teaches “a plurality of resilient fingers extending from the first base and substantially aligned transversely to the path direction,” Final Act. 2—3, it does not teach the plurality of fingers “defm[e] at least one row of individual fingers.” To cure this deficiency, the Examiner relies on Bavelloni, which relates to a “pressure shoe structure” used in a “plate glass conveyor belt whereon [ ] plate glass is transported edgewise” for beveling or chamfering. Bavelloni 3 Appeal 2016-001335 Application 13/994,263 col. 1,11. 6—10. Applying Bavelloni to Egger, the Examiner finds the combination “teaches a plurality of resilient fingers (4) defining at least one row of individual fingers.” Final Act. 4. The Examiner then finds it would have been obvious to incorporate the row of individual fingers from Bavelloni into the device taught by Egger “for the purpose of providing individual control and engagement of the article along its length, thus preventing rotation or displacement of the article during conveyance.” Final Act. 7; Ans. 15. Appellants contend the Examiner has improperly combined Egger and Bavelloni for several reasons. App. Br. 4—6. First, Appellants argue the Examiner “has impermissibly defined a problem of rotation of displacement of an article being conveyed” based on the disclosure expressing a need for secure engagement of an article. App. Br. 5 (citing Spec. 1 5). Appellants further argue the rationale suggested by the Examiner is flawed because “control and engagement of an article along its length to prevent rotation or displacement” is not necessary or even a concern in Bavelloni. App. Br. 5. More specifically, Appellants contend because Bavelloni is directed to a plate glass cutting machine which carries a single uniformly-shaped sheet of plate glass, there is no concern rotation or displacement or a need to provide individual control, as a single large piece of glass is the only item fed through the conveyor in Bavelloni. App. Br. 5—6. Finally, Appellants argue the Examiner’s rationale “ignores substantial difference[s] between handling containers, such as disclosed in Egger, and plate glass, as disclosed in Bavelloni”. Reply Br. 4. According to Appellants, the fingers in Bavelloni are necessarily stiff because they are designed to tightly hold plate glass, which would discourage an ordinarily skilled artisan from using them in a 4 Appeal 2016-001335 Application 13/994,263 way that they independently deflect and flex to hold drink bottles such as those shown in Egger. Reply Br. 4—5. We are persuaded that the Examiner has erred. As noted above, the Examiner finds a person of ordinary skill in the art would have sought to modify the single finger of Egger with the multiple finger configuration of Bavelloni because doing so would “provide individual control and engagement of the article along its length, thus preventing rotation or displacement of the article during conveyance.” Final Act. 7; Ans. 15. We agree with Appellants that a skilled artisan would not look to Bavelloni to provide this benefit. Bavelloni is primarily concerned with providing a solution to the problem that certain small pieces of glass are too small to be effectively fed through glass edge processing equipment. Bavelloni col. 1, 11. 16—26. The solution proposed by Bavelloni to the problem of small glass pieces is the use of a non-interfering small plate that can be extended into the space between the fingers and the surface supporting the glass place to secure a small glass plate that does not extend from the supporting surface into the fingers. Bavelloni col. 1,11. 3 5—48. In contrast, Egger relates to a conveyor of open containers such as empty bottles through a cleaning station. We do not agree with the Examiner that a person of ordinary skill in the art seeking to improve the bottle conveyor of Egger would look to Bavelloni to “provide individual control and engagement of the article along its length” to prevent rotation or displacement during conveyance. We note Egger’s device appears to already provide individual control and engagement of bottles. For example, Egger states: 5 Appeal 2016-001335 Application 13/994,263 FIG. 3 clearly illustrates that no further guiding means are provided for guiding the containers B, e.g. bottles, but that the guiding and conveying of the containers B is performed exclusively by means of the gripping elements 12, 13. The lips 15a, 15b of the gripping elements are made of an elastic material, adjusted to the materials of the containers B to be conveyed such that a high frictional force is developed between the particular gripping elements 12, 13 and the container B to be conveyed. Thus, no relative movement between the lips of the gripping elements 12, 13 and the related container B occurs during the transport of the containers. Egger col. 6,11. 20-31. We further note that, contrary to the Examiner’s rationale of preventing rotation of items as they move along the belt, Egger actually rotates them by purpose and design as shown in Figure 4, reproduced below. i I U V V 1 ; / — F?S'> „ —«ci : i : I !^%V \ ' . £ " .,0s , *, .« \ ~T tu Figure 4 of Egger shows a conveyor belt with gripping elements securing individual items and rotating them up to 180 degrees as they move along the conveyor belt Egger describes this rotational movement, stating “[t]his illustration clearly exhibits that the containers B are rotated along the input area by 180° around the central longitudinal access of the conveying apparatus 1.” Egger col. 6, 11. 56—59. This rotational movement is a central aspect of Egger’s design. 6 Appeal 2016-001335 Application 13/994,263 Without it, the containers in the conveyor would not reliably be able to be processed through a cleaning station or a draining station in which “any fluid possibly present in the containers can flow out under the influence of gravity.” Egger col. 7,11. 2—3. As such, the Examiner’s rationale of incorporating Bavelloni to prevent rotation does not support the proposed combination. In sum, we find the Examiner’s rationale for modifying Egger to incorporate Bavelloni’s longitudinal row configuration of blocks does not articulate reasoning with rational underpinnings, as it is inconsistent with the purpose and operation of Egger. Moreover, we are not persuaded a person of ordinary skill in the art seeking to improve upon a bottle conveyor such as Egger would have looked to a very different type of conveying device such as Bavelloni without a clear suggestion for doing so. The Examiner’s reasoning does not provide any such suggestion. Accordingly, we do not sustain the rejection of independent claim 17, nor do we sustain the rejection of claims 1—16 and 20—23 which depend therefrom. DECISION The Examiner’s rejection of claims 1—17 and 20—23 is reversed. REVERSED 7 Copy with citationCopy as parenthetical citation
