TURNER, STEVEN M. AMUNDSON, and JASON M. REPKO, Administrative Patent Judges. AMUNDSON, Administrative Patent Judge. DECISION ON APPEAL Appellant1 seeks our review under 35 U.S.C. § 134(a) from a final rejection of claims 1–27, i.e., all pending claims. We have jurisdiction under 35 U.S.C. § 6(b). We affirm in part. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42 (2018). Appellant identifies the real party in interest as nLIGHT, Inc. Appeal Br. 3. Appeal 2019-004019 Application 15/143,314 2 STATEMENT OF THE CASE The Invention According to the Specification, the invention concerns “fiber optic inspection apparatuses and methods.” Spec. 1:10.2 Although the Specification states that “[c]onventional methods of inspecting and documenting an output end of industrial fibers used in fiber laser products are inconvenient or inadequate,” the Specification fails to explain how the invention addresses any deficiencies in conventional methods. See id. at 1:13–2:10. Exemplary Claims Independent claims 1 and 15 exemplify the claims at issue and read as follows (with formatting added for clarity): 1. An apparatus, comprising: a camera; a dark field illumination source; and a fiber inspection housing including a fiber connector input situated to receive an optical fiber connector so that an optical fiber output end of the optical fiber connector is removably insertable into an interior region of the fiber inspection housing and securable at a predetermined location in the interior region, 2 This decision uses the following abbreviations: “Spec.” for the Specification, filed April 29, 2016; “Final Act.” for the Final Office Action, mailed July 10, 2018; “Advisory Act.” for the Advisory Action, mailed September 28, 2018; “Appeal Br.” for the Appeal Brief, filed December 10, 2018; “Ans.” for the Examiner’s Answer, mailed March 1, 2019; and “Reply Br.” for the Reply Brief, filed April 28, 2019. Appeal 2019-004019 Application 15/143,314 3 a camera input situated to receive and secure the camera so that the camera is in optical communication with the interior region and the optical fiber output end, and a dark field illumination source input situated to receive the dark field illumination source so that light emitted from the dark field illumination source is received by the optical fiber output end at a dark field illumination angle and is scattered by contamination or defects associated with the optical fiber output end so as to be detectable by the camera. 15. An optical fiber inspection method, comprising: removably receiving in an optical fiber connector input of a fiber inspection housing an optical fiber connector having an optical fiber axis so that an output fiber end of the optical fiber connector is situated at a predetermined location in an interior region of the fiber inspection housing; bright field illuminating through the interior region of the fiber inspection housing at least one surface of the output fiber end and obtaining a first image of the at least one surface with a camera optically coupled to the output fiber end through the interior region; and dark field illuminating through the interior region the at least one surface of the output fiber end and obtaining a second image of the at least one surface with the camera. Appeal Br. 18, 20 (Claims App.). The Prior Art Supporting the Rejections on Appeal As evidence of unpatentability under 35 U.S.C. § 103, the Examiner relies on the following prior art: Name Reference Date Vodyanoy et al.

ANALYSIS We have reviewed the § 103 rejections in light of Appellant’s arguments that the Examiner erred. For the reasons explained below, we agree with the Examiner’s obviousness determinations for claims 1–4, 7–9, Name Reference Date Kiani et al. (“Kiani”) US 2004/0125366 A1 July 1, 2004 Suzuki et al. (“Suzuki”) US 2006/0153503 A1 July 13, 2006 Castonguay et al. (“Castonguay”) US 2012/0180298 A1 July 19, 2012 Wilson et al. (“Wilson”) US 2013/0229650 A1 Sept. 5, 2013 Hallett et al. (“Hallett”) US 2015/0063756 A1 Mar. 5, 2015 Tong et al. (“Tong”) US 2016/0178858 A1 June 23, 2016 (filed July 17, 2014) Appeal 2019-004019 Application 15/143,314 5 11–16, and 18–27 but disagree with the Examiner’s obviousness determinations for claims 5, 6, 10, and 17. We adopt the Examiner’s findings and reasoning in the Final Office Action, Advisory Action, and Answer for claims 1–4, 7–9, 11–16, and 18–27. See Final Act. 2–15; Advisory Act. 1–2; Ans. 3–17. We add the following to address and emphasize specific findings and arguments. The § 103 Rejection of Claims 1–6, 8, 10, 13–16, and 19–26 INDEPENDENT CLAIMS 1 AND 15 As noted above, the § 103 rejection of claims 1 and 15 rests on Kiani, Hallett, and Wilson. See Final Act. 5–7, 10–11. Appellant argues that the Examiner erred in rejecting claims 1 and 15 because an ordinarily skilled artisan would not have been motivated “to modify Kiani to ‘provide the optical coupling that makes sure that the fiber optic connectors’ are suitably spliced as disclosed by Hallett.” Appeal Br. 8 (quoting Final Act. 7); see Reply Br. 2. According to Appellant, “providing such an optical coupling” would (1) “prevent the ‘camera [being] in optical communication with the interior region and the optical fiber output end’” and (2) “prevent any related inspection of the corresponding optical fiber output end.” Appeal Br. 8–9 (quoting claim 1); see Reply Br. 2. In addition, Appellant contends that the proposed combination would “render the prior art unsatisfactory for its intended purpose.” Appeal Br. 9. Appellant’s arguments do not persuade us of Examiner error because they rest on a misunderstanding of the proposed combination. The Examiner does not propose applying Hallett’s teachings about splicing to Kiani’s inspection apparatus to “make[] sure that the fiber optic connectors’ are suitably spliced.” See Final Act. 2–3, 6–7; Ans. 3–4, 11. Appeal 2019-004019 Application 15/143,314 6 Rather, the Examiner correctly finds that Kiani discloses an apparatus for inspecting an optical fiber connector. Final Act. 4, 10–11 (citing Kiani ¶¶ 2, 63, 71, Figs. 1, 8); Ans. 7–8; see Kiani ¶¶ 2–3, 63, 71, 93, Figs. 1–2, 8–9. Further, the Examiner correctly finds that Hallett discloses a mechanism for (1) removably inserting an optical fiber connector into a tool and (2) securely holding the optical fiber connector at a predetermined location when inserted into the tool. Final Act. 2, 6 (citing Hallett ¶¶ 11, 38, 40, Figs. 1–6); Ans. 3–4, 11 (citing Hallett ¶¶ 1–6, 11, 38, 40, Figs. 1–6); see Hallett ¶¶ 1–6, 11, 38, 40, Figs. 1–6. The Examiner proposes applying Hallett’s teachings about a mechanism for removably inserting an optical fiber connector into a tool to Kiani’s inspection apparatus. See Final Act. 2–3, 6–7; Ans. 3–4, 11. Specifically, Kiani explains that “contamination (e.g., oil, dirt, etc.) and/or surface imperfections (e.g., scratches, protrusions, dents, etc.) at one or more of the optical interfaces could result in malformed fiber optic connections that provide improper light signal transfer (e.g., degradation or loss of a light signal).” Kiani ¶ 2. Kiani also explains that optical equipment manufacturers and users “strive to keep the optical interfaces of their optical connectors clean and free of damage to maximize light energy transfer and to minimize signal degradation of the light signals exchanged between the optical interfaces.” Id. Similarly, Hallett discloses that a challenge for optical interfaces “is making sure that the fiber optic connectors do not significantly attenuate, reflect, or otherwise alter the optical signals being transmitted.” Hallett ¶ 5. The Examiner properly reasons that Hallett’s disclosure about ensuring that “fiber optic connectors do not significantly attenuate, reflect, Appeal 2019-004019 Application 15/143,314 7 or otherwise alter the optical signals being transmitted” would have motivated an ordinarily skilled artisan to modify Kiani’s inspection apparatus according to Hallett’s teachings about a mechanism for removably inserting an optical fiber connector into a tool. See Final Act. 2–3, 6–7; Ans. 3–4, 11. Also, “the law does not require that the references be combined for the reasons contemplated by the inventor.” See In re Beattie, 974 F.2d 1309, 1312 (Fed. Cir. 1992); see also Outdry Techs. Corp. v. Geox S.p.A., 859 F.3d 1364, 1371 (Fed. Cir. 2017). “[T]he desire to enhance commercial opportunities by improving a product or process is universal . . . .” DyStar Textilfarben GmbH v. C.H. Patrick Co., 464 F.3d 1356, 1368 (Fed. Cir. 2006); see In re Peterson, 315 F.3d 1325, 1330 (Fed. Cir. 2003). An “implicit motivation to combine” may result from a desire to make a product or process “stronger, cheaper, cleaner, faster, lighter, smaller, more durable, or more efficient.” DyStar, 464 F.3d at 1368. Here, the Examiner determines that combining Hallett’s and Wilson’s teachings with Kiani’s teachings would improve Kiani’s inspection apparatus, e.g., by reducing signal reflection and attenuation. See Final Act. 2–3, 6–7; Advisory Act. 1; Ans. 3–4, 11. Appellant contends that the Kiani-Hallett-Wilson combination “appears to be based on impermissible hindsight.” Appeal Br. 9. We disagree. The Examiner explains that the analysis “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made.” Final Act. 2–3 (quoting In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971)); Ans. 12. In addition, an explicit analysis “whether there was an apparent reason to combine” references Appeal 2019-004019 Application 15/143,314 8 reduces “the risk of . . . patent examiners falling prey to hindsight bias.” See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418, 421 (2007). Here, the Examiner’s explicit analysis of the reasons to combine Kiani, Hallett, and Wilson demonstrates that the Examiner did not fall prey to hindsight bias. See Final Act. 3–4, 7 (citing Hallett ¶¶ 4–5; Wilson ¶ 4); Ans. 4, 11–12 (citing Hallett ¶¶ 1–6; Wilson ¶ 4). Appellant asserts that the Examiner fails to “provide facts or rational underpinnings to support the conclusory statements regarding obviousness.” Appeal Br. 9. We disagree. As discussed above, the Examiner correctly finds that Kiani discloses an apparatus for inspecting an optical fiber connector. Final Act. 4, 10–11 (citing Kiani ¶¶ 2, 63, 71, Figs. 1, 8); Ans. 7–8; see Kiani ¶¶ 2–3, 63, 71, 93, Figs. 1–2, 8–9. As also discussed above, the Examiner correctly finds that Hallett discloses a mechanism for (1) removably inserting an optical fiber connector into a tool and (2) securely holding the optical fiber connector at a predetermined location when inserted into the tool. Final Act. 2, 6 (citing Hallett ¶¶ 11, 38, 40, Figs. 1–6); Ans. 3–4, 11, 13 (citing Hallett ¶¶ 1–6, 11, 38, 40, Figs. 1–6); see Hallett ¶¶ 1–6, 11, 38, 40, Figs. 1–6. According to the Examiner, combining the teachings of the references would improve Kiani’s inspection apparatus, e.g., by reducing signal reflection and attenuation. See Final Act. 2–3, 6–7; Advisory Act. 1; Ans. 3–4, 11. Thus, the Examiner provides a “rational underpinning to support the legal conclusion of obviousness.” See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006); Ans. 13. For the reasons discussed above, Appellant’s arguments have not persuaded us that the Examiner erred in rejecting claims 1 and 15 for obviousness based on Kiani, Hallett, and Wilson. In our view, the claimed Appeal 2019-004019 Application 15/143,314 9 subject matter exemplifies the principle that “[t]he combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” See KSR, 550 U.S. at 416. Thus, we sustain the § 103 rejection of claims 1 and 15. DEPENDENT CLAIMS 2–4, 16, AND 19–26 Claims 2–4 depend directly from claim 1, and claims 16 and 19–26 depend directly or indirectly from claim 15. Appellant does not argue patentability separately for these dependent claims. See Appeal Br. 6–16; Reply Br. 1–5. Thus, we sustain the § 103 rejection of these dependent claims for the same reasons as claims 1 and 15. See 37 C.F.R. § 41.37(c)(1)(iv). DEPENDENT CLAIM 5 Claim 5 depends indirectly from claim 1 and specifies that a “bright field illumination source is spaced apart from the camera on the opposite side of an optical axis of the fiber connector input and situated to direct a bright field illumination along an optical axis that is at an oblique angle with respect to an optical axis of the camera.” Appeal Br. 18–19 (Claims App.). Appellant notes that the Examiner cites Kiani’s Figures 8 and 41 for teaching claim 5’s subject matter. Appeal Br. 10; Reply Br. 2; see Final Act. 3, 7–8; Ans. 5, 13. Figures 8 and 41 are reproduced below: Appeal 2019-004019 Application 15/143,314 10 Figure 8 is a top view of the various components of an inspection assembly rotating through an angle around the point A to obtain an image of an optical interface, i.e., optical interface 116. Kiani ¶¶ 21, 23, 93, Fig. 8. Figure 41 is a side view of an interferometer configuration “suitable for use by the inspection assembly.” Id. ¶¶ 56, 124, Fig. 41. Appellant argues that the Examiner erred in rejecting claim 5 because monochromatic light source 452 in Figure 41 “emits light along an optical axis that is perpendicular to an optical axis of a beam received by an aligned sensor 458” corresponding to claim 5’s “camera.” Appeal Br. 10. According to Appellant, the Figure 41 arrangement “directs the light to a ferrule endface surface 116 (with beam splitter 454) along an optical axis that is coaxial with the optical axis of the beam received by the sensor 458.” Id. Appellant contends that “[n]either ‘perpendicular’ nor ‘coaxial’ is ‘oblique’” as required by claim 5. Id. Further, Appellant asserts that “the mere panning of the dark field illuminator” in Figure 8 “is not the same as a bright field illumination” and that the Examiner “fails to establish that there would be any motivation to make Kiani’s dark field illuminator into a bright field illuminator.” Reply Br. 2. Appeal 2019-004019 Application 15/143,314 11 In response, the Examiner explains that “Kiani discloses rotate the lens 206 and the dark field illuminator 204 that also could be a bright field illuminator, hereinafter collectively referred to as the lens assembly 212, about the Y-axis.” Ans. 13. Based on the record before us, we agree with Appellant that the Examiner has not adequately explained how the cited portions of Kiani teach or suggest a bright field illumination source “situated to direct a bright field illumination along an optical axis that is at an oblique angle with respect to an optical axis of the camera” as required by claim 5. Figure 41 does not depict the required “oblique angle.” Kiani ¶ 124, Fig. 41. In addition, Figure 8 depicts a dark field illumination source (dark field illuminator 204), not a bright field illumination source, rotating through an angle around the point A. Id. ¶ 93, Fig. 8. As Appellant asserts, the Examiner “fails to establish that there would be any motivation to make Kiani’s dark field illuminator into a bright field illuminator.” See Ans. 13; Reply Br. 2. Hence, we do not sustain the § 103 rejection of claim 5. DEPENDENT CLAIM 6 Claim 6 depends indirectly from claim 1 and specifies that a “bright field illumination source is adjacent to or adjoining the camera and situated to direct a bright field illumination along an optical axis as emitted from the bright field illumination source that is spaced apart and parallel to an optical axis of the camera.” Appeal Br. 19 (Claims App.). Appellant notes that the Examiner cites Kiani’s Figure 13 for teaching claim 6’s subject matter. Appeal Br. 11–12; see Final Act. 8; Ans. 5, 13–14. Figure 13 is reproduced below: Appeal 2019-004019 Application 15/143,314 12 Figure 13 is a top view of the various components of an inspection assembly that “employs prisms to aim a sensor subassembly along the X-axis.” Kiani ¶¶ 28, 97, Fig. 13. Appellant argues that the Examiner erred in rejecting claim 6 because the illumination from light source 202 in Figure 13 is (1) “directed perpendicular from an optical axis of the imaging sensor 200” corresponding to claim 6’s “camera” and (2) not “spaced apart and parallel to an optical axis of the camera” as required by claim 6. Appeal Br. 11–12. Appellant also argues that the “deformation of the light paths by the prism members 230 does not remedy the failure to disclose” claim 6’s subject matter. Id. at 12. In response, the Examiner explains that “it can be seen in Fig.13, on the left side of prism member 230-B, the deformed light path is parallel but apart away from the optical axis of image senor 200.” Ans. 14. Based on the record before us, we agree with Appellant that the Examiner has not adequately explained how the cited portions of Kiani teach or suggest a bright field illumination source “situated to direct a bright field illumination along an optical axis as emitted from the bright field illumination source that is spaced apart and parallel to an optical axis of the Appeal 2019-004019 Application 15/143,314 13 camera” as required by claim 6. Kiani’s Figures 14 and 15 are side views of the inspection assembly depicted in Figure 13. Kiani ¶¶ 28–30, 97, Figs. 13–15. Figures 14 and 15 show that the illumination from light source 202 strikes coaxial illumination beam splitter 208 and then becomes coincident with, not parallel to, the optical axis of imaging sensor 200. Id. ¶¶ 92, 97–98, Figs. 14–15. After the coincident light paths for imaging sensor 200 and light source 202 pass through lens assembly 212, prism members 230-A and 230-B deform the coincident light paths in the same way. Id. ¶ 97, Figs. 13–15. Because prism members 230-A and 230-B deform the coincident light paths in the same way, prism members 230-A and 230-B do not cause the coincident light paths to diverge, e.g., to become parallel. Id. ¶¶ 97–98, Figs. 13–15. Hence, we do not sustain the § 103 rejection of claim 6. DEPENDENT CLAIM 8 Claim 8 depends directly from claim 1 and specifies that “the fiber inspection housing includes a cleaning access port situated to allow cleaning of the optical fiber output end situated at the predetermined location in the interior region.” Appeal Br. 19 (Claims App.). Appellant argues that the Examiner erred in rejecting claim 8 because (1) the Examiner maps the claimed “fiber inspection housing” to Kiani’s card cage 72 and (2) card cage 72 “is separate from” the inspection system. Appeal Br. 12. Appellant also argues that the narrow slot in card cage 72 for cleaning an optical connector 78 “is the result of removing a circuit card to provide access for the inspection system, and therefore only exists in the absence of” the inspection system. Reply Br. 3. Appeal 2019-004019 Application 15/143,314 14 Appellant’s arguments do not persuade us of Examiner error because the Examiner correctly finds that Kiani discloses a cleaning system for the optical connectors in card cage 72. Advisory Act. 2 (citing Kiani ¶ 65); Ans. 14 (citing Kiani ¶¶ 2, 63–67, Fig. 1); see Kiani ¶¶ 2–3, 63–67, 71–72, Figs. 1–2. In particular, Kiani explains that inspection system 50 preferably “resides on a portable cart with a cleaning system so that the user can clean the optical connectors 78 before and/or after inspection.” Kiani ¶ 65. In addition, Kiani discloses shutters 112 that open to provide an access port allowing cleaning and inspection. Id. ¶¶ 67, 71–72, Figs. 1–2; see id. ¶ 64. Hence, we sustain the § 103 rejection of claim 8. DEPENDENT CLAIM 10 Claim 10 depends directly from claim 1 and further requires “a diffuser situated to diffuse light from the bright field illumination source so as to improve a camera image detail.” Appeal Br. 19 (Claims App.). Appellant argues that the Examiner erred in rejecting claim 10 because “Wilson’s beam splitter is not a ‘diffuser’ and does not ‘diffuse light from the bright field illumination source so as to improve a camera image detail’” as required by claim 10. Appeal Br. 13; see Reply Br. 4. Appellant also argues that even if Wilson’s beam splitter were a “diffuser,” the Examiner “has not articulated any reasoning with rational underpinnings to explain how a person of ordinary skill would combine Wilson’s alleged ‘diffuser’ in the manner claimed.” Appeal Br. 13. In response, the Examiner explains that “the beam splitter of Wilson would have been understood by a person of ordinary skill in the art as a beam diffuser.” Ans. 14; see Advisory Act. 2. Appeal 2019-004019 Application 15/143,314 15 Based on the record before us, we agree with Appellant that the Examiner has not adequately explained how the cited portions of Wilson teach or suggest a “diffuser” according to claim 10. Wilson discloses a “beam splitter” for diverting a portion of incoming radiation. Wilson ¶ 17. A “beam splitter” divides “a beam of radiation into two or more parts.”3 In contrast, a “diffuser” distributes “the light of a lamp evenly,” e.g., to soften lighting.4 Hence, we do not sustain the § 103 rejection of claim 10. DEPENDENT CLAIM 13 Claim 13 depends directly from claim 1 and specifies that “the camera is part of a mobile device, and the camera input is situated to receive the mobile device so that the mobile device camera is removably insertable into the camera input so as to detect defects on the optical fiber output end.” Appeal Br. 20 (Claims App.). Appellant argues that the Examiner erred in rejecting claim 13 because Wilson discloses “mobile devices” but “is completely silent about a ‘camera input [that] is situated to receive [a] mobile device’” as required by claim 13. Appeal Br. 13. Appellant also argues that “nowhere does Wilson teach its camera is ‘also a mobile device.’” Reply Br. 4. Appellant’s arguments do not persuade us of Examiner error because the Examiner correctly finds that Wilson discloses (1) an apparatus for cleaning and inspecting fiber optic end faces that includes a camera and (2) implementing features of the apparatus with a mobile device. Final Act. 3–4, 8; Advisory Act. 2; Ans. 5, 15; see Wilson ¶¶ 4, 56–57, 60, 119, code (57), Fig. 1. Specifically, Wilson explains that its disclosures “may be 3 See https://www.merriam-webster.com/dictionary/beam%20splitter. 4 See https://www.merriam-webster.com/dictionary/diffuser. Appeal 2019-004019 Application 15/143,314 16 implemented on or through mobile devices,” such as cell phones and mobile phones. Wilson ¶ 119. A person of ordinary skill “must be presumed to know something” about the art “apart from what the references disclose.” In re Jacoby, 309 F.2d 513, 516 (CCPA 1962). “A person of ordinary skill is also a person of ordinary creativity, not an automaton.” KSR, 550 U.S. at 421. Here, those skilled in the art would have known that cell phones and mobile phones as disclosed in Wilson typically include cameras. Hence, we sustain the § 103 rejection of claim 13. DEPENDENT CLAIM 14 Claim 14 depends directly from claim 1 and specifies that “the fiber inspection housing is portable so that an image of the optical fiber output end with the camera is obtainable without requiring the mounting of the fiber inspection housing to a surface.” Appeal Br. 20 (Claims App.). Appellant argues that the Examiner erred in rejecting claim 14 because (1) the Examiner maps the claimed “fiber inspection housing” to Kiani’s card cage 72 and (2) card cage 72 “is not ‘portable’ as recited in claim 14.” Appeal Br. 14; see Reply Br. 4. Appellant’s argument does not persuade us of Examiner error because the Examiner correctly finds that Kiani discloses a portable inspection apparatus and that Hallett discloses a portable housing. Final Act. 3, 8 (citing Kiani ¶ 65, Fig. 2; Hallett Fig. 2); Advisory Act. 2; Ans. 5–6, 15 (citing Kiani ¶¶ 62, 65, Figs. 1–2; Hallett Fig. 2); see Kiani ¶¶ 62–66, Figs. 1–2; Hallett ¶¶ 10–11, Figs. 2–4. “Combining the teachings of references does not involve an ability to combine their specific structures.” In re Nievelt, 482 F.2d 965, 968 (CCPA 1973) (emphasis by the court). Appeal 2019-004019 Application 15/143,314 17 Here, the combined disclosures in the references teach or suggest claim 14’s subject matter. See Final Act. 3, 8; Advisory Act. 2; Ans. 5–6, 15. Hence, we sustain the § 103 rejection of claim 14. The § 103 Rejection of Claim 7 Claim 7 depends directly from claim 1 and specifies that “the fiber connector input is situated to receive and secure the optical fiber output end at the predetermined location so that the optical fiber output end is rotatable about an optical fiber axis.” Appeal Br. 19 (Claims App.). As noted above, the § 103 rejection of claim 7 rests on Kiani, Hallett, Wilson, and Suzuki. See Final Act. 9. Appellant argues that the Examiner erred in rejecting claim 7 because Suzuki’s paragraph 12 “states that ‘[i]deally, the goal is to provide for a floating connection of the ferrules within the sleeve, with minimal if any ferrule rotation about the optical axis of each connector,’ ‘[i]f the ferrules are allowed to rotate, or if excessive inclination of the ferrules is permitted, then the optimum connection between the connectors being joined will likely not be achieved,’ and ‘[t]he prevention of ferrule rotation around the optical axis is also important for optimal tunability of the ferrules.’” Appeal Br. 14 (quoting Suzuki ¶ 12). Appellant’s argument does not persuade us of Examiner error because the Examiner correctly finds that Suzuki discloses a ferrule for an “optical fiber output end [that] is rotatable about an optical fiber axis” according to claim 7. Advisory Act. 2; Ans. 15–16 (citing Suzuki ¶ 54, code (57), Fig. 1); see Suzuki ¶¶ 51–54, code (57), Fig. 1. Specifically, Suzuki explains that if the ferrule “is pushed far enough axially backward so as to be disengaged from the limiters,” the ferrule “can be rotated,” e.g., “in 90° Appeal 2019-004019 Application 15/143,314 18 increments to a total of four different positions.” Suzuki ¶ 54. Consequently, the combined disclosures in the references teach or suggest claim 7’s subject matter. See Advisory Act. 2; Ans. 15–16. Hence, we sustain the § 103 rejection of claim 7. The § 103 Rejection of Claims 9, 18, and 27 Claim 9 depends directly from claim 1 and further requires “a baffle situated to block at least a portion of the light emitted by the dark field illumination source that propagates at greater than the dark field illumination angle or that propagates to surfaces other than the optical fiber output end.” Appeal Br. 19 (Claims App.). Claim 18 depends directly from claim 15 and specifies a range for the angle of incidence of the dark field illumination light. Id. at 21. Claim 27 depends directly from claim 15 and further requires “varying the wavelength of the dark field illumination light or bright field illumination light.” Id. at 22. As noted above, the § 103 rejection of claims 9, 18, and 27 rests on Kiani, Hallett, Wilson, and Vodyanoy. Final Act. 9–10, 13. Appellant argues that the Examiner erred in rejecting claims 9, 18, and 27 because “Vodyanoy is non-analogous art.” Appeal Br. 16; see Reply Br. 5. In particular, Appellant contends that Vodyanoy relates to “optical microscopes that use ‘high-energy light from a phenomenon known as non-resonant Raman scattering to illuminate a living biological specimen.’” Appeal Br. 16 (quoting Vodyanoy ¶ 2). Appellant also contends that Vodyanoy “would not logically commend itself to an inventor’s attention in fiber endface inspection for various reasons, including at least because Vodyanoy’s microscopes direct light through a specimen 200 with a Appeal 2019-004019 Application 15/143,314 19 darkfield condenser 60, rather than at the biological specimen 200.” Id. (emphasis by Appellant). In response, the Examiner explains that Vodyanoy addresses the same problem as claim 9’s “baffle,” in particular, blocking a portion of the dark field light directed toward the item under inspection. Advisory Act. 1; Ans. 16 (citing Spec. 9:5–6). Hence, the Examiner determines that Vodyanoy is analogous art. Ans. 16–17; see Advisory Act. 1. Appellant’s arguments do not persuade us of Examiner error because we agree with the Examiner that Vodyanoy is analogous art. See Ans. 16–17. The scope of analogous art includes references “from the same field of endeavor” as the claimed invention and references “reasonably pertinent” to a problem facing the inventor. In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004); see In re Wood, 599 F.2d 1032, 1036 (CCPA 1979). A “reasonably pertinent” reference “logically would have commended itself to an inventor’s attention in considering” a problem facing the inventor. See In re Clay, 966 F.2d 656, 659 (Fed. Cir. 1992). The Specification describes a baffle situated to “block[] a portion of the dark field light so as to limit the incidence of light” directed toward the item under inspection, and thus improve image quality. Spec. 9:5–8. Consistent with the Specification, claim 9 recites “a baffle situated to block at least a portion of the light emitted by the dark field illumination source.” Appeal Br. 19. Like the Specification and claim 9, Vodyanoy describes a baffle situated to block a portion of the dark field light so as to limit the incidence of light directed toward the item under inspection, and thus improve image quality. Vodyanoy ¶¶ 80–81, Fig. 3; see Final Act. 9; Advisory Act. 1; Appeal 2019-004019 Application 15/143,314 20 Ans. 6, 16. Specifically, Vodyanoy discloses dark field condenser 60 with disk-shaped and centrally located annular stop 62. Vodyanoy ¶¶ 80–81, Fig. 3. With annular stop 62, dark field condenser 60 blocks a portion of the dark field light 300 so that “a hollow cylinder of light passes around the edges of the annular stop 62 and strikes the condenser lens 64, which bends the light toward the specimen 200.” Id. ¶ 81, Fig. 3; see id. ¶¶ 72, 80. Accordingly, the dark field light 300 “exiting the condenser lens 64 is shaped like a hollow cone” and “can be positioned and focused such that its vertex strikes the specimen 200.” Id. ¶ 81, Fig. 3. As those skilled in the art would have understood, suitably positioning and focusing the dark field light 300 exiting the condenser lens 64 would improve image quality. Also, like claim 9’s “baffle,” dark field condenser 60 blocks a portion of the dark field light 300 that would propagate to surfaces other than the specimen 200. Id. ¶ 81, Fig. 3; see Final Act. 9; Advisory Act. 1; Ans. 6. Because Vodyanoy addresses the same problem as claim 9’s “baffle,” Vodyanoy “logically would have commended itself to an inventor’s attention in considering” a problem facing the inventor. See Clay, 966 F.2d at 659. Thus, Vodyanoy is analogous art. See Advisory Act. 1; Ans. 16–17. Hence, we sustain the § 103 rejection of claims 9, 18, and 27. The § 103 Rejection of Claims 11 and 12 Claims 11 and 12 depend directly from claim 1. Appellant does not argue patentability separately for these dependent claims. See Appeal Br. 6–16; Reply Br. 1–5. Thus, we sustain the § 103 rejection of these dependent claims for the same reasons as claim 1. See 37 C.F.R. § 41.37(c)(1)(iv). Appeal 2019-004019 Application 15/143,314 21 The § 103 Rejection of Claim 17 Claim 17 depends directly from claim 15 and further requires “securing the optical fiber connector in the fiber inspection housing against axial and lateral translation with respect to the optical fiber axis; and rotating the optical fiber connector.” Appeal Br. 20–21 (Claims App.). As noted above, the § 103 rejection of claim 17 rests on Kiani, Hallett, Wilson, and Castonguay. See Final Act. 13. Appellant argues that the Examiner erred in rejecting claim 17 because Castonguay’s activation mechanism “does not rotate an optical fiber connector but instead uses a cam” to bias splice parts together to secure optical fibers “in relation to each other for splicing.” Appeal Br. 15. According to Appellant, “Castonguay is silent about ‘securing the optical fiber connector in the fiber inspection housing against axial and lateral translation with respect to the optical fiber axis; and rotating the optical fiber connector,’ as recited in claim 17.” Id. In response, the Examiner explains that Castonguay discloses that “a fiber optical connector is received and secured axially during being terminated by a fiber optical cable, and preventing lateral translation during lateral connector removal.” Ans. 16 (citing Castonguay ¶¶ 7, 11, 84, Fig. 28). Based on the record before us, we agree with Appellant that the Examiner has not adequately explained how the cited portions of Castonguay teach or suggest securing an optical fiber connector “against axial and lateral translation” and “rotating the optical fiber connector” as required by claim 17. Although the Examiner cites portions of Castonguay that teach or suggest securing an optical fiber connector “against axial and Appeal 2019-004019 Application 15/143,314 22 lateral translation,” the cited portions do not teach or suggest “rotating the optical fiber connector.” See Ans. 16 (citing Castonguay ¶¶ 7, 11, 84, Fig. 28); Castonguay ¶¶ 7, 11, 84, Fig. 28. Hence, we do not sustain the § 103 rejection of claim 17. CONCLUSION We affirm the Examiner’s decision to reject claims 1–4, 7–9, 11–16, and 18–27. We reverse the Examiner’s decision to reject claims 5, 6, 10, and 17.
