KENNEDY, and MERRELL C. CASHION, JR., Administrative Patent Judges. HANLON, Administrative Patent Judge. DECISION ON APPEAL A. STATEMENT OF THE CASE The Appellant1 filed an appeal under 35 U.S.C. § 134(a) from an Examiner’s decision rejecting claims 13–18.2 We have jurisdiction under 35 U.S.C. § 6(b). A hearing was held on December 17, 2019. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies the real party in interest as Tetra Laval Holdings & Finance S.A. Appeal Brief dated March 9, 2018 (“App. Br.”), at 1. 2 Claims 1–6 and 19–24 are also pending. Claims 1–6 are withdrawn from consideration, and claims 19–24 are allowed. Appeal 2018-008862 Application 13/378,008 2 We REVERSE. The claims on appeal are directed to a device for maintaining a gas flow barrier between two interconnected volumes of a package filling machine. Spec. 1, ll. 5–10. According to the Appellant’s invention, the first volume has a first degree of sterilization and the second volume has a different, second degree of sterilization. Spec. 3, ll. 21–23. The Appellant discloses that the open end of the package may occupy the first volume and the opposite end of the package may occupy the second volume. Spec. 4, ll. 16–18. The package may be filled with a food product. Spec. 1, ll. 8–10. The Appellant discloses that “it is not necessary for the entire outer surface of the package to be kept sterile[; i]t suffices that the inside of the package and an area adjacent to the boundary between the inside and the outside is kept aseptic or sterile.” Spec. 4, ll. 19–21. Appellant’s Figure 2, reproduced below, illustrates an embodiment of the invention. Appellant’s Figure 2 is a schematic sectional view, orthogonal to a transportation direction, of a filling machine according to an embodiment of the Appellant’s invention. According to the Appellant, nozzles 116 are arranged in the top of the filling zone of the filling machine and inject sterile air downwards. Spec. 7, ll. 30–32. Appeal 2018-008862 Application 13/378,008 3 The injected air from each nozzle 116 is said to form a diverging flow, as indicated by the dotted lines extending from the nozzle opening. Spec. 7, l. 32–8, l. 1. In the Appellant’s device, a first nozzle is closer to a first side wall than a second nozzle, and the second nozzle is closer to a second side wall than the first nozzle. See Appellant’s Fig. 2. The first and second nozzles are arranged and configured such that the divergent jet injected from the first nozzle intersects the first side wall, and the divergent jet injected from the second nozzle intersects the second side wall. The divergent jets of gas meet in an interface area between the first volume and the second volume. The horizontal dash-dotted line in Appellant’s Figure 2 is said to indicate the approximate position of the interface area, wherein the first volume is above the line and the second volume is below the line. Spec. 8, ll. 5–7. The Appellant discloses that “[i]n the interface area, there will always be a unidirectional flow, efficiently forming a gas flow barrier preventing mass transport from the second volume (II) to the first [volume] (I).” Spec. 8, ll. 8–10. The sterile first volume is thus said to remain sterile independently of the atmosphere in the second volume. Spec. 8, ll. 11–12. Independent claim 13 is reproduced below from the Claims Appendix to the Appeal Brief. The limitation at issue is italicized. 13. A device for maintenance of a gas flow barrier between two volumes of a channel in a filling machine, the channel being configured for transportation of packages in a length direction of the channel, the device comprising: a first volume with a first degree of sterilization; a second volume with a second degree of sterilization that is lower than the first degree of sterilization; nozzles in an upper portion of the first volume; a gas evacuation opening in the second volume; Appeal 2018-008862 Application 13/378,008 4 the first volume and the second volume meeting in an interface area extending in a length direction of the channel; the channel including first and second side walls on opposite sides of the channel in a width direction of the channel, the width direction being orthogonal to the length direction of the channel; the nozzles configured to inject turbulent, divergent, jets of gas directed toward the interface area, such that the divergent jets of gas meet in the interface area to generate a unidirectional flow in a first direction from the first volume toward the second volume in the interface area, the unidirectional flow forming the gas flow barrier preventing a flow in a second direction from the second volume toward the first volume; and the nozzles including first and second nozzles spaced apart from one another in the width direction of the channel, the first nozzle being closer to the first side wall than the second nozzle, and the second nozzle being closer to the second side wall than the first nozzle, the first and second nozzles being arranged and configured such that the divergent jet injected from the first nozzle intersects the first side wall, and the divergent jet injected from the second nozzle intersects the second side wall. App. Br., Claims Appendix 1–2 (emphasis added). The Examiner maintains the following rejections on appeal: (1) claims 13 and 15–17 under 35 U.S.C. § 103(a) as unpatentable over Martensson et al.3 in view of Iwaki4; (2) claim 14 under 35 U.S.C. § 103(a) as unpatentable over Martensson in view of Iwaki and further in view of Py et al.5; and 3 US 2006/0067856 A1, published March 30, 2006 (“Martensson”). 4 JP 11-178515 A, published July 6, 1999 (“Iwaki”). In this Decision on Appeal, we refer to the English translation dated October 6, 2017, which is of record in the instant Application. 5 US 2006/0231519 A1, published October 19, 2006 (“Py”). Appeal 2018-008862 Application 13/378,008 5 (3) claim 18 under 35 U.S.C. § 103(a) as unpatentable over Martensson in view of Iwaki and further in view of Quetel et al.6 or Iwashita et al.7 B. DISCUSSION The Examiner finds Martensson discloses a device that is configured for transporting packages in the length direction of a channel comprising, inter alia, (1) first volume 18 with a first degree of sterilization, (2) second volume 19 with a second, lower degree of sterilization, and (3) an interface area (i.e., any location between first volume 18 and second volume 19). Non-Final Act. 3–4.8 Martensson’s Figure 1 is reproduced below. Martensson’s Figure 1 illustrates a sterilizing device. 6 US 2005/0118057 A1, published June 2, 2005 (“Quetel”). 7 US 2007/0253863 A1, published November 1, 2007 (“Iwashita”). 8 Non-Final Action dated October 13, 2017. Appeal 2018-008862 Application 13/378,008 6 The Examiner finds that nozzles in first volume 18 are capable of injecting turbulent, divergent jets of gas directed toward the interface area. Non-Final Act. 4. The Examiner, however, finds Martensson does not teach that first and second nozzles [are] spaced apart from one another in the width direction of the channel, the first nozzle being closer to the first side wall than the second nozzle, the second nozzle being closer to the second side wall than the first nozzle, the first and second nozzles being arranged and configured such that the divergent jet injected from the first nozzle intersects the first side wall, and the divergent jet injected from the second nozzle intersects the second wall [as claimed]. Non-Final Act. 4. The Examiner finds that it was well known in the art to provide nozzles at any location, such as along the top wall of a sterilization channel, and finds that Iwaki exemplifies such a device. Non-Final Act. 4–5. Iwaki’s Figure 2 is reproduced below. Iwaki’s Figure 2 is a cross sectional view of Iwaki’s disclosed device. Appeal 2018-008862 Application 13/378,008 7 The Examiner finds Iwaki’s device comprises, inter alia, first nozzles (i.e., left most nozzle 12) and second nozzles (i.e., right most nozzle 12) spaced apart from one another in the width direction of channel 2. Non-Final Act. 5. The Examiner finds left most nozzle 12 is closer to a first side wall (i.e., left side wall of channel 2) than right most nozzle 12, and right most nozzle 12 is closer to a second side wall (i.e., right side wall of channel 2) than left most nozzle 12. Non- Final Act. 5. The Examiner further finds that divergent jets injected from left most nozzle 12 and right most nozzle 12 are capable of intersecting the left side wall and the right side wall, respectively. Non-Final Act. 5–6. The Examiner concludes that it would have been obvious to one of ordinary skill in the art to modify Martensson’s device with the nozzle configuration disclosed in Iwaki. Non-Final Act. 6. The Appellant argues that “Iwaki does not describe that nozzles spaced apart along the width direction of the channel inject jets intersecting both side walls of the channel as claimed.” App. Br. 10. According to the Appellant, [o]ne reason first and second nozzles in the [Appellant’s] device . . . are spaced from one another along the width direction of the channel and so that the jets intersect the side walls is to create an interface area between the first and second volumes. As claimed, this interface area is the area at which the first volume having a higher degree of sterilization meets the second volume having the lower degree of sterilization. . . . Martensson and Iwaki do not seek to create an interface area as claimed, and do not in fact create such an interface area.[9] App. Br. 11 (emphasis added). 9 The Examiner finds that the interface area in Martensson is an arbitrary location between first volume 18 and second volume 19. See Non-Final Act. 4 (finding that the interface area in Martensson is any location between first volume 18 and second volume 19). Appeal 2018-008862 Application 13/378,008 8 In response, the Examiner states that Appellant “admits” that Iwaki is capable of left most and right most nozzles 12 intersecting respective left and right side walls of Iwaki’s channel 2. Ans. 11 (citing App. Br. 10, ll. 9–10).10 The Appellant, on the other hand, argues that “[t]he Appellant has made no such admission.” Reply Br. 1. The Appellant’s argument is supported by the record. See Reply Br. 1–2.11 The Examiner also finds Iwaki discloses that “‘the whole processing space’ is utilized for processing (i.e. addition of ozone into a space).” Ans. 11–12 (citing Iwaki ¶ 6. Therefore, the Examiner concludes that it would have been obvious to one of ordinary skill in the art to position the nozzles so that the nozzles inject jets of fluid that intersects [sic, intersect] the side walls as claimed in order that the entire process volume/space is supplied with sterilizing fluid as this would optimize the sterilization of objects. Ans. 12 (emphasis added). In response, the Appellant contends that Iwaki “does not talk in terms of the jets from the nozzles intersecting side walls as claimed.” Reply Br. 3. Indeed, Iwaki merely refers to the “whole processing space,” nothing more. Iwaki ¶ 6. We find that this disclosure in Iwaki encompasses a myriad of unidentified nozzle configurations that, absent the Appellant’s disclosure, does not direct one of ordinary skill in the art to the claimed nozzle configuration. Therefore, the Examiner has failed to establish, by a preponderance of the evidence, that Iwaki either describes or renders obvious first and second nozzles arranged and configured as recited in claim 13. See In re Oetiker, 977 F.2d 1443, 1445 (Fed. 10 Examiner’s Answer dated July 16, 2018. 11 Reply Brief dated September 13, 2018. Appeal 2018-008862 Application 13/378,008 9 Cir. 1992) (examiner bears the initial burden of presenting a prima facie case of unpatentability). Claim 13 also recites that the first and second nozzles are configured to inject divergent jets of gas that intersect the first side wall and the second side wall, respectively, and meet in an interface area to generate a unidirectional flow from a first volume having a first degree of sterilization toward a second volume having a second, different degree of sterilization. Having failed to show that the claimed nozzle configuration is described or rendered obvious by Iwaki, the Examiner has likewise failed to show that the claimed interface area is rendered obvious by the combined teachings of Martensson and Iwaki. For the reasons set forth above, the obviousness rejection of claim 13 and dependent claims 15–17 is not sustained. The Examiner does not rely on the remaining prior art of record to cure the deficiency in the obviousness rejection of claim 13 identified above. Therefore, the obviousness rejections of claims 14 and 18 also are not sustained. C. CONCLUSION The Examiner’s decision is reversed.
