CALVE, and NATHAN A. ENGELS, Administrative Patent Judges. CAL VE, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellants appeal under 35 U.S.C. § 134(a) from the Office Action finally rejecting claims 1-20. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM-IN-PART. 1 Cardiac Pacemakers, Inc. is identified as the real party in interest. Appeal Br. 3. Appeal 2018-004699 Application 14/953,987 CLAIMED SUBJECT MATTER Claims 1, 11, and 19 are independent. Claim 1 is reproduced below. 1. An implantable medical device (IMD) configured for implantation within a patient, the IMD comprising: a hermetically sealed elongated housing having a length dimension and a width dimension with the length dimension being greater than the width dimension; two or more electrodes electrically exposed outside of the housing; an energy storage device disposed within the housing; a circuit disposed within the housing and electrically connected to the energy storage device and the two or more electrodes; wherein the circuit comprises two or more island sections with each island section electrically connected to at least one other island section by a ribbon section, wherein each island section has two opposing major surfaces; and a first one of the two or more island sections and a second one of the two or more island sections are stacked within the housing such that one of the two opposing major surfaces of the first island section faces one of the two opposing major surfaces of the second island section and is transverse to the length dimension. REJECTIONS Claims 1-10 are rejected under 35 U.S.C. § 103 as unpatentable over Greenhut (US 2014/0214104 Al, pub. July 31, 2014) and Wahlstrand (US 2004/0176818 Al, pub. Sept. 9, 2004). 2 Claims 19 and 20 are rejected under 35 U.S.C. § 103 as unpatentable over Wahlstrand. 2 The Examiner relies on Chiao (US 2016/0220814 Al, pub. Aug. 4, 2016) to teach circular circuit boards as recited in claim 4. Final Act. 5; Ans. 3. 2 Appeal 2018-004699 Application 14/953,987 Claims 11-17 are rejected under 35 U.S.C. § 103 as unpatentable over Greenhut, Wahlstrand, and Swanson (US 2011/0230923 Al, pub. Sept. 22, 2011). Claim 18 is rejected under 35 U.S.C. § 103 as unpatentable over Greenhut, Wahlstrand, Swanson, and Maghribi (US 2006/0042830 Al, pub. Mar. 2, 2006). ANALYSIS Claims 1-10 Unpatentable Over Greenhut and Wahlstrand Appellants argue claims 1, 3, and 5-10 as a group. Appeal Br. 6-11. We select claim 1 as representative, with claims 3 and 5-10 standing or falling with claim 1. 37 C.F.R. § 4I.37(c)(l)(iv). The Examiner relies on Greenhut to teach an elongated leadless pacemaker having energy storage (power source 102), electrodes 52, 60, and circuits (processor 90, memory 92, telemetry module 94, shock detector 99, activity sensor 100). Final Act. 2. The Examiner relies on Wahlstrand to teach circuits formed as island sections, connected by a ribbon, and stacked in the housing in Figure 13. Id. The Examiner determines that it would have been obvious to use the stacked configuration of Wahlstrand in Greenhut for the "predictable result of a more compact design, thus saving space inside the housing of the IMD." Id. The Examiner determines that making stacked island sections transverse to a length of an elongated housing is an obvious design choice because "the circuit boards of Figure 13 of Wahlstrand can be made small enough to fit transversely into Greenhut's elongated housing (Fig. 3) as "a simple matter of scaling the size of the circuit boards to make it fit" so less space is used in the housing. Id. The Examiner finds that parts of Wahlstrand's circuit board 160 and flex tape 162 would be transverse to the housing length. Ans. 2. 3 Appeal 2018-004699 Application 14/953,987 Appellants argue that Figure 5 of Greenhut is a functional block diagram that does not show or describe the actual physical layout of circuits, components, or a "circuit board" and therefore provides no discussion of how a non-disclosed circuit board would be disposed within Greenhut's elongated leadless pacemaker. Appeal Br. 7-8. Appellants also argue that a skilled artisan would understand the circuit board in Figure 13 of Wahlstrand as configured to fit within housing 36 of control module 30 in Figure 12 in an orientation that is parallel to the major dimension of the housing rather than transverse to the major dimension (length) as claimed. Id. at 8-9. These arguments are not persuasive for the following reasons. First, claim 1 recites "a circuit" rather than a "circuit board" as Appellants argue. Second, Greenhut teaches that the elements depicted in the functional block diagram of Figure 5 correspond to circuits and electrical components. See Greenhut ,r,r 105 (processor 90 is an application specific integrated circuit (ASIC), multiple components, more ASICs, or other discrete or integrated logic circuitry), 110 (signal generator 96 includes circuitry for measuring a capture threshold), 112 (timing and control module of processor 90 may be a hardware circuit, ASIC, or microprocessor). Third, the Examiner correctly finds that Wahlstrand teaches circuit board 160 having separate islands with electrical components thereon. Final Act. 2 (citing Wahlstrand, Fig. 13). We agree with Appellants that Figure 13 of Wahlstrand does not teach a transverse orientation of circuit board 160 relative to a housing as claimed. However, the Examiner relies on Wahlstrand's teaching of stacked islands and reasons that the orientation of those islands relative to a housing would be an obvious design choice within the level of ordinary skill in the art for predictable results of using less space in the housing. Ans. 2; Final Act. 2. 4 Appeal 2018-004699 Application 14/953,987 Appellants ascribe no criticality to the claimed transverse orientation of the circuit islands. In their Reply Brief, Appellants argue that a stacked, transverse arrangement consumes less space within the housing. Reply Br. 2-3. However, such space savings are dependent on the relative shapes and dimensions of the circuit islands and housing, neither of which is claimed. In the Specification, Appellants disclose a desire to reduce the volume used for electrical circuits to enhance the volume used for an energy storage device (battery). Spec. ,r 3. The Specification discloses ways to achieve this reduction by stacking the circuits, using a common substrate for islands and ribbon sections, flexible circuits, three islands, filling a transverse area of a housing at least 80% or 90% with circuits, and alternatively or additionally, orienting major surfaces of island sections transverse to a length dimension of the housing. Id. ,r,r 4--33. The Specification also discloses that a stacked, transverse orientation of circuit islands may consume 5% to 50% of the total height 514 of an implantable medical device 14. Id. ,r 95, Fig. 7. The height consumed by energy storage device 502 ranges from 50% to 95% of the total height 514 ofIMD 500. Id. Appellants also argue that the Examiner has not established that the circuit boards of Figure 13 of Wahlstrand can be made small enough to fit transversely into the elongated housing in Figure 3 of Greenhut. Appeal Br. 9. Appellants argue that the Examiner provides no basis for asserting that a skilled artisan would have been motivated to configure Wahlstrand's circuit boards to fit transversely into the elongated housing in Figure 3 of Greenhut. Id. Appellants argue that even if Wahlstrand teaches that the substrate and circuit board are made from flex tape, the circuit board would be placed in parallel to the length of the elongate shape, not transverse. Id. at 10. 5 Appeal 2018-004699 Application 14/953,987 Appellants' arguments are not persuasive for the following reasons. First, Wahlstrand teaches to form circuit board 160 in sections (islands) and stack the sections along major opposed surfaces to permit circuit board 160 to be inserted into a smaller, cylindrical housing 3 6. W ahlstrand ,r 91. The Examiner reasons correctly that this teaching provides motivation to form a circuit board in multiple, smaller sections, as desired, to fit efficiently into a volume of an IMD housing. Ans. 2; Final Act. 2. Recognizing that skilled artisans are persons of ordinary creativity, the Examiner reasons that they would be motivated and able to size circuit boards to fit economically within a particular housing to use space therein more efficiently. Ans. 2-3. These findings and reasoning are consistent with W ahlstrand' s teachings that The size and shape of an IMD housing is dependent on the sizes and shapes of the components of the IMD. Large components common to most IMDs include a battery, a telemetry coil, and a circuit board that carries digital circuits, e.g., integrated circuit chips and/or a microprocessor, and analog circuit components. Attempts have been made to reduce the size of the IMD housing by reducing the size of these components, changing the shape of these components, and organizing these components within the IMD housing to avoid empty space within the housing. Despite these efforts to reduce the size of IMD housings, the size, shape and rigidity of IMD housings still greatly limits the locations within the human body where an IMD can be practically implanted. W ahlstrand ,r 19. W ahlstrand thus teaches to reduce the size and change the shape of components and organize these components within an IMD housing to avoid empty space in the housing and thereby reduce the size of the IMD housing. Id. These teachings also support the Examiner's reasoning that the transverse orientation of circuit islands is an obvious design choice where Appellants do not establish its criticality as compared to the closest prior art. 6 Appeal 2018-004699 Application 14/953,987 A skilled artisan would be confronted with finite options when placing stacked circuit islands inside an IMD housing. The circuit islands could be oriented parallel or transverse to a length of the housing. The orientation is a design choice because it does not affect the functioning of the IMD or the circuit. See ACCO Brands Corp. v. Fellowes, Inc., 813 F.3d 1361, 1367 (Fed. Cir. 2016) (explaining that where the prior art located two sensors in the shredder's feed, a skilled artisan was left with two design choices: (1) to place the thickness sensor above the presence sensor in the feed or (2) to place the thickness sensor below the presence sensor, and either design choice is an obvious combination of prior art elements) ( citing KSR Int 'l Co. v. Teleflex Inc., 550 U.S. 398,421 (2007) ("When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense."); In re Conte, 36 F. App'x 446,451 (Fed. Cir. 2002) (non-precedential) (holding that the difference between prior art's upward-opening slot and claimed downward-opening slot was insignificant design choice because both types of slots would retain the rubber band on the front of the gun barrel). Any space-saving advantage of a transverse orientation depends on the shape, size, volume, and number of circuit islands compared to the shape and size (including cross-sectional shape and size) and volume of an IMD housing as well as the shapes, sizes, and volumes of other components in the housing. See Wahlstrand ,r 19. None of these variables is recited in claim 1. Any purported advantages are not commensurate with the scope of claim 1. 7 Appeal 2018-004699 Application 14/953,987 Nor do Appellants address the Examiner's determination that the orientation of the stacked islands is an obvious design choice that lacks criticality. Appellants do not argue or show that Greenhut's IMD would operate any differently when the circuits were stacked parallel rather than transverse to the length of the IMD housing. Thus, the Examiner had a sound basis for treating this feature as an obvious design choice. See In re Kuhle, 526 F.2d 553,555 (CCPA 1975) (holding that the placement of an electrical contact was an obvious design choice because it operated in well- known manner with no novel or unexpected result); cf In re Gal, 980 F .2d 717, 719-20 (Fed. Cir. 1992) (holding that a custom chip design was not an obvious design choice as it functioned differently than the prior art design). Even if Wahlstrand is understood to teach a parallel orientation (see Appeal Br. 9-10; Reply Br. 5---6), the Examiner modifies Greenhut's IMD housing, which positions power source 102 and electrical components in the same housing (Figs. 3, 5), not separate housings 36, 38 as in Wahlstrand. Thus, we sustain the rejection of claims 1, 3, and 5-10. Claim 2 Claim 2 depends from claim 1 and recites "wherein the two or more island sections and the ribbon section have a common substrate." Claims App. 2. 3 The Examiner finds that Wahlstrand teaches to make the entire circuit board 160 from flex tape, which forms a common substrate. Final Act. 2. Appellants argue that flex tape may form a common portion, but there is no teaching of electrically connecting island sections with a ribbon section that is part of the circuit board as claimed. Appeal Br. 11. 3 All citations to the claims are taken from the Supplemental Appeal Brief, filed Nov. 14, 2017, as the Response to the Non-Compliant Appeal Brief. 8 Appeal 2018-004699 Application 14/953,987 Appellants' arguments are not persuasive primarily because they are not commensurate with the scope of claim 2, which does not recite a circuit board or island sections connected with a ribbon section that is part of the circuit board as Appellants assert. Claim 2 requires the two or more island sections and ribbon section to have a common substrate. The Examiner correctly finds that Wahlstrand teaches a circuit board comprising sections connected by flex tape regions 162 (Fig. 13) and also teaches that circuit board 160 may be constructed entirely of flex tape. Wahlstrand ,r 91. We find that forming circuit board 160 and flex tape region 162 entirely of flex tape would create a circuit board having a common substrate, i.e., flex tape. See Ans. 3. Appellants' arguments recognize that the flex tape may provide a common portion but do not explain why this common portion is not also a common substrate as claimed. Indeed, the Specification discloses that the circuit and ribbon sections may comprise a flexible circuit that may include a flexible substrate with two or more islands and one or more ribbon sections electrically connected thereto. See Spec. ,r,r 6, 8, 17, 19, 31, and 39. Thus, we sustain the rejection of claim 2. Claim 4 Claim 4 depends from claim 1 and recites "wherein the two or more island sections are circular and comprise printed circuit boards." Claims App. 2. The Examiner finds that printed circuit boards are well known in the art as evidenced by Aghassian (para. 6) and obvious to use. Final Act. 3. The Examiner also finds that the circular shape is an obvious design choice yielding predictable results. Id. The Examiner finds that paragraph 36 of Chiao (US 2016/0220814 Al, pub. Aug. 4, 2016) teaches to make circuit boards in different shapes including circular shapes. Ans. 3. 9 Appeal 2018-004699 Application 14/953,987 Appellants argue that it is not appropriate to assert that the circular shape is a mere design choice because a skilled artisan would have no reason to make a printed circuit board circular and making a printed circuit board circular would serve no purpose in the devices of Wahlstrand or Greenhut. Appeal Br. 11. Appellants argue that there is no suggestion to place circuit boards transverse to a longitudinal axis of the housing so there would be no purpose in shaping the printed circuit boards as claimed. Id. Appellants' arguments are not persuasive for the following reasons. First, Appellants' arguments do not address the Examiner's determination that a circular shape for a circuit board is an obvious design choice and thus do not apprise us of Examiner error in this regard. Second, Appellants do not argue any criticality or different functionality for the circular shape. The Specification discloses that island sections 202, 204 may be circular in shape in some examples, "but this is not required." Spec. ,r 75. The Specification discloses that, in other examples, islands 202, 204 may be triangular, square, ovular, or any other suitable shape. Id. The Specification discloses other examples in which the shape of island sections 202, 204 may match a cross section shape of an implantable medical device. Id. Thus, the Examiner had a sound basis to conclude that the circular shape of the printed circuit board is an obvious design choice. Furthermore, the Examiner relied on Chiao to teach that circuit boards can have a variety of different shapes to include circular shapes and using/substituting circular circuit boards for the circuit boards of the IMD of the modified Greenhut would yield predictable results over other circuit board shapes. Ans. 3. As discussed above, Wahlstrand teaches to vary the shapes of IMD components. Wahlstrand ,r 19. Thus, we sustain the rejection of claim 4. 10 Appeal 2018-004699 Application 14/953,987 Claims 19 and 20 Unpatentable Over Wahlstrand. Independent claim 19 recites a flexible circuit with a flexible substrate comprising two or more circular island sections electrically connected by a ribbon section on a common substrate with the island sections. Claims App. 5. An application specific integrated circuit (ASIC) is mounted on one island section, and each ribbon section can bend to position the island sections in a parallel, stacked relationship transverse to a length dimension of an elongated device housing. Id. The Examiner relies on Wahlstrand to teach these features. Final Act. 3. The Examiner determines that it would have been an obvious design choice yielding predictable results to make the island sections of Wahlstrand a circular shape. Id. The Examiner also determines it would have been an obvious design choice to position the stacked island sections transverse to a length of an elongated housing because the circuit boards can be made small enough to fit transversely into the elongated housing shown in Figure 12. Id. The Examiner further determines that it would have been obvious to size the circuit boards to fit and additionally finds that, by making the circuit boards fit transversely, less space would be taken up in the housing of the IMD. Id. Appellants argue the Examiner cites no support for the finding that the circuit boards of Figure 13 can be made small enough to fit transversely into the elongated housing of Figure 12. Appeal Br. 12. Appellants also argue that Wahlstrand does not describe a flexible circuit with island sections that are planar with a circular shape, nor does Wahlstrand describe the stacked island sections as being positioned transverse to a length dimension of an elongated cylindrical device housing. Id. 11 Appeal 2018-004699 Application 14/953,987 Appellants' arguments are not persuasive for the following reasons. First, the Examiner's findings that Wahlstrand's circuit boards can be sized small enough to fit transversely in a housing are supported by the teachings of W ahlstrand. As discussed above, Wahlstrand teaches to size circuit board 160 into two smaller islands. Wahlstrand ,r 91, Fig. 13. Wahlstrand teaches generally that IMD components are sized smaller, shaped, and organized to fit within IMD housings to avoid empty spaces. Id. ,r 19. Second, the Examiner determines that a circular shape and transverse orientation of circuit islands are obvious design choices. We agree with this determination for the reasons discussed for claims 1 and 4. Appellants have not demonstrated any criticality or different functionality for these features to preclude their treatment as design choices. Instead, as discussed above, the Specifications discloses these features among many different ways to configure the circuits depending on the IMD housing and other components to achieve the same functions. Thus, we sustain the rejection of claim 19. Claim 20 Claim 20 depends from claim 19 and recites that the flexible circuit further comprises "one or more electrical components mounted on another one of the island sections that does not have the ASIC." Claims App. 5. The Examiner finds that a skilled artisan would understand that such placement of the circuit components is a design choice yielding predictable results. Ans. 4. The Examiner also finds that the Specification provides no disclosure that the claimed placement yields unexpected or important advantages unknown in the art. Id. The Examiner further finds that Figure 13 of Wahlstrand shows island sections connected by a ribbon section where any type of circuitry could be placed on the island sections. Id. 12 Appeal 2018-004699 Application 14/953,987 Appellants argue that Wahlstrand may mention an ASIC but does not teach a flexible circuit with other electrical components mounted on another island section. Appeal Br. 13. Appellants argue that the cited art does not teach a flexible circuit with "one or more electrical components mounted on another of the island sections that does not have the ASIC." Id. The Examiner has the better position in view of Wahlstrand's teaching of circuit board 160 comprising separate islands with different components mounted thereon. Wahlstrand ,r 91, Fig. 13; Ans. 4. Wahlstrand teaches that control module 30 in housing 36 includes processor 60, which may be an ASIC, microprocessor, digital signal processor, or other logic circuitry. Wahlstrand ,r 74. Wahlstrand teaches that control module 30 comprises other components and circuits. Id. ,r,r 75-78. The Examiner reasonably finds that the components are spread among the two islands illustrated in Figure 13 such that an ASIC is positioned on one of the two islands and other electrical components are positioned on the other of the two island sections as claimed. Ans. 4. Thus, we sustain the rejection of claim 20. Claims 11-17 Unpatentable Over Greenhut, Wahlstrand, and Swanson Independent claim 11 recites an implantable medical device (IMD) comprising an elongated housing having a major and minor dimension, two or more electrodes, an energy storage device with a feedthrough extending away from the energy storage device along the major dimension of the elongated housing, and a flexible circuit and substrate in two or more island sections with opposing major surfaces that extend transverse to the major dimension of the elongated housing when the island sections are stacked in the housing. Claims App. 3. 13 Appeal 2018-004699 Application 14/953,987 The Examiner relies on Greenhut and W ahlstrand to teach features of claim 11 that are the same as or similar to those recited in claims 1 and 19 and Swanson to teach a feedthrough 408 that connects a battery 402 and circuit elements 404 in Figure la. Final Act. 4; Ans. 4. The Examiner finds that Swanson's feedthrough 408 extends along a major axis of the housing in Figure la, and it would extend along the major axis of the elongated housing of Greenhut. Final Act. 4. The Examiner determines that it would have been obvious to use Swanson's feedthrough to connect circuits of Greenhut to the battery along a major axis of the housing "since it would yield predictable results, and result in a more compact design." Id. Appellants argue that Swanson does not remedy the shortcomings of Greenhut and Wahlstrand regarding the orientation of a stack circuit board. Appeal Br. 14. Appellants also argue that there is no teaching in Wahlstrand to orient the circuit boards transversely. Id. This latter argument is not persuasive because the orientation of the circuit island sections is an obvious design choice for the reasons discussed above for the rejection of claim 1. Thus, there are no deficiencies in Greenhut and Wahlstrand for Swanson to cure in this regard. Accordingly, we sustain the rejection of claim 11. Claim 12 Claim 12 depends from claim 11 and recites 'wherein each ribbon section is more flexible than the island sections." Claims App. 4. The Examiner finds that Wahlstrand illustrates this feature as flex tape or ribbons 162 in the embodiments of paragraph 91. Ans. 4--5. Appellants argue that the Examiner fails to point to any teaching of the references of this claimed feature and instead relies on design choice. Appeal Br. 14--15. 14 Appeal 2018-004699 Application 14/953,987 The Examiner has the better position in view of Wahlstrand's teaching of circuit board 160 comprising two island sections connected by flex tape 162. Wahlstrand ,r 91, Fig. 13. The Examiner correctly finds that flex tape 162 is more flexible than the two island sections in embodiments where the two island sections are not also formed of flex tape. Ans. 4--5. As shown in Figure 13, flex tape section 162 is flexible enough to be bent into a C-shape to connect the circuit board sections, which are shown as planar, rigid island sections. Thus we sustain the rejection of claim 12. Claim 13 Claim 13 depends from claim 11 and recites "wherein the flexible circuit comprises three island sections." Claims App. 4. The Examiner finds that having a third island section connected to other island sections by a ribbon section would merely be duplicative of what is already taught in Wahlstrand, Figure 13 for two island sections. Ans. 5. The Examiner also finds that a third section would not yield unpredictable results but would be a reasonable thing to do if all of the circuitry did not fit on just two island sections. Id. Appellants argue that the Examiner fails to identify any disclosure in the prior art and instead appears to rely on obvious design choice whenever a claimed feature is not found in the prior art. Appeal Br. 15-16. Appellants argue that a specific structure is claimed that allows a more compact design as disclosed in the Specification. Id. at 16. The Examiner's reasoning is supported by a rational underpinning in that circuitry that does not fit within a housing when placed on two islands would be able to fit within a housing when formed into three smaller island sections that fit more easily within a housing section. Ans. 5. 15 Appeal 2018-004699 Application 14/953,987 As discussed above, Wahlstrand provides a rational underpinning for this reasoning because it teaches to form circuit 160 as multiple islands and it teaches to reduce the size and shape or circuits and other components and group them to fit inside IMD housings with less wasted space. Wahlstrand ,r,r 19, 91, Fig. 13. The Examiner reasonably concludes that a skilled artisan would have been motivated to form a circuit board into three smaller island sections if two island sections did not fit within an IMD housing. Ans. 5. Thus, we sustain the rejection of claim 13. Claims 14 and 15 Claims 14 and 15 depend from claim 13 and require respectively that the first island section is positioned between the second and third island sections, or that the second island section is positioned between the first and third island sections. Claims App. 4. The Examiner finds that neither feature provides a more compact design as Appellants argue to be the case but instead yield the same compact design with three islands. Ans. 5. Appellants argue that the Examiner has not cited any disclosure in the prior art as teaching this feature and instead relies on obvious design choice. Appeal Br. 1 7. Appellant argues that these claimed arrangements are more than just shifting parts around and instead allow a more compact design as disclosed in the Specification. Id. The Examiner has the better position in view of the lack of criticality or different functionality argued or ascribed to these features. There is no indication in the Specification nor any argument by Appellants that island sections function differently when stacked in different orders as claimed. Thus, we sustain the rejection of claims 14 and 15. 16 Appeal 2018-004699 Application 14/953,987 Claim 18 Unpatentable Over Greenhut, Wahlstrand, Swanson, and Maghribi Claim 18 depends from claim 11 and recites "wherein each ribbon section comprises a metal portion bonded between two polymer portions, and each of the island sections comprises a first metal portion bonded between two polymer portions, and second metal portions bonded to the two polymer portions." Claims App. 4. The Examiner relies on Maghribi to teach a ribbon with metal traces bonded between two polymer portions and Wahlstrand to teach a flex tape. Final Act. 4--5; Ans. 5---6. The Examiner reasons that each flex tape island of W ahlstrand could be made as taught in Maghribi with metal traces bonded between polymers. Ans. 5---6. Appellants argue that the Examiner has not explained where the prior art also teaches "second metal portions bonded to the two polymer portions" as claimed. Appeal Br. 19. We agree. Accordingly, we do not sustain the rejection of claim 18. DECISION We affirm the rejections of claims 1-17, 19, and 20 and we reverse the rejection of claim 18. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l )(iv). AFFIRMED-IN-PART 17 Copy with citationCopy as parenthetical citation
