“II. ANALYSIS A. LEVEL OF ORDINARY SKILL Petitioner defines the person of ordinary skill in the art as follows: As of February 2006, a person of ordinary skill in the art (“POSITA”) would have been a person with a degree in 1 The Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), amended 35 U.S.C. § 103. Because the challenged claims of the ’414 patent have an effective filing date before the effective date of the applicable AIA amendments, we refer to the pre-AIA version of 35 U.S.C. § 103 throughout this Decision. 2 Mauer et al., U.S. Patent No. 7,395,085 B1, issued July 1, 2008 (Ex. 1005, “Mauer”). 3 Waylett et al., U.S. Patent No. 8,184,603 B2, issued May 22, 2012 (Ex. 1006, “Waylett”). computer science, electrical or computer engineering, physics, or a similar discipline . . . [and] would also have at least two years of relevant experience including, for example, work related to telecommunications networks. Pet. 3 (citing Ex. 1003 ¶ 54). The institution decision adopted Petitioner’s definition of a person having ordinary skill in the art. Dec. on Inst. 11–12. Patent Owner applied this definition for its response. Resp. 19. Petitioner’s undisputed definition of a person of ordinary skill in the art is reasonable and consistent with the prior art and ’414 patent specification. Based on the record before us, we adopt Petitioner’s undisputed proposal. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“Petitioner does not submit constructions for any claim terms. According to Petitioner, “[t]he Board construes claims under the same standard used in civil actions in federal district court.

But we do not need to construe “distributed mobile architecture (DMA)” to resolve this inter partes review. We thus do not construe this claim term. We also do not discern a need to construe explicitly any other claim language because doing so would have no effect on our analyses below of Petitioner’s asserted grounds and will not assist in resolving the present controversy between the parties.

“a) Combination of Mauer and Waylett In support of both Ground 1 and Ground 2, Petitioner argues that a person of ordinary skill in the art would have been motivated to combine Mauer’s and Waylett’s disclosures, “using Waylett’s Network-in-a-box 224 in each of Mauer’s WWAN 14 and WLAN 12, resulting in at least two DMA systems.” Pet. 11–13. Asserting that “Mauer teaches providing sufficient network coverage by use of different kinds of networks, network interfaces, and protocols,” Petitioner contends that a person of ordinary skill in the art would have recognized that “Waylett discloses an inexpensive way to implement the same networks used in Mauer’s WWAN 14 and WLAN 12.” Id. Citing similarities in Mauer’s and Waylett’s systems, Petitioner argues that “a POSITA would have been able to modify Mauer’s WWAN 14 and WLAN 12 networks so that each network uses Waylett’s NIB 224.” Id. at 14. According to Petitioner, the combination would have included a number of beneficial features from Mauer. Id. at 14–15. Petitioner further advances three reasons that a person of ordinary skill would have had to combine the references’ teaching. Id. at 15–16. First, asserting that Waylett discloses cost benefits and Mauer discloses “an improved method and system for notifying mobile stations,” Petitioner contends the “references each provide reasoning” to combine their disclosures. Id. at 15. Second, Petitioner argues that a person of ordinary skill in the art would have been motivated to “improve Mauer’s distributed wireless network system by consolidating it into a single box, making it compact in design allowing for faster deployment.” Id. at 16. “Third, Waylett’s NIB would help mitigate the shared concern of Mauer—that is, reaching a mobile station as it roams or moves outside of the service or coverage area.” Id.” slip op. at 24

“Petitioner does not establish that Mauer sends calls to voicemail based on the two determinations claim 1 recites. Resp. 55–56. In particular, as we explain above, claim 1 requires making use of the DPR after first determining the second mobile subscriber is not located within a first wireless coverage area based on HLR and VLR information and also determining that the second mobile subscriber is not located within a second wireless coverage area based on certain CLR information. The Petition, at best, attempts to establish that Mauer directs to voicemail when a “communication session cannot be established over the first or second wireless network.” Pet. 37. But a general determination that a “communication session cannot be established” does not teach or suggest claim 1’s specific requirements that first, the DPR is utilized in the specific circumstance that the second mobile subscriber is not located within the first wireless coverage area (with this determination being made based on HLR and VLR information), and second, that the DPR is also not located within the second wireless coverage area (with this determination being made based on CLR information). See PO Sur-Reply 8–9; Ex. 2001 ¶¶ 111–113. For the reasons above, Petitioner does not establish by a preponderance of the evidence that the combined art teaches or suggests the final “when” recitation of claim 1.” slip op. at 29

“First, neither the Petition nor Dr. Kazanzides explains how Doo’s curved plane teaches the claimed “volume.” See Pet. 36–37; Ex. 1012 ¶¶ 74–75 (essentially repeating the Petition). The Petition merely asserts that Doo’s image in Figure 7 “is confined within the volume of the virtual 3D shape illustrated in Figure 9,” without explaining how the shape of Figure 9 has a “volume.” Pet. 37. The Reply does no better, asserting that “Doo’s shape 532 in Figure 9 and shape 432 in Figure 7 are virtual 3D shapes.” Reply 18. This statement is conclusory and does not explain how Doo’s “false 3D” shapes have volume. Petitioner further attempts to establish that Doo’s disclosure of Figure 9’s shape 532 as “mimic[ing] the surface curvature of the patient’s body” is evidence that Doo discloses a 3D shape. Id. (citing Ex. 1008 ¶ 76). This argument, however, is unpersuasive because it takes Doo’s statement out of context. Doo explains that Figure 9’s warped “two-dimensional image 532 . . . mimic[s] the surface curvature of the patient’s body,” not that it has volume. See Ex. 1008 ¶ 76 (emphasis added). In other words, even though Doo’s shape 532 of Figure 9, when projected on a patient’s body (as in Figure 7) may appear to a surgeon like a 9 Our Institution Decision did not rely on Petitioner’s theory based on Doo Figures 7–9. We discuss our Institution Decision’s reasoning below under Petitioner’s second theory based on Doo Figures 6 and 11. half-cylinder shape having a volume, Doo’s technique avoids rendering a 3D shape like a half-cylinder (hence calling these “false 3D shapes”) because it instead simulates the body’s curvature with a mere curved two-dimensional plane. Second, we find that Doo’s curved plane does not, in fact, have a volume.10 Instead, Doo’s curved plane is a 2D plane merely “wrapped around an axis.” See Ex. 1008 ¶¶ 75–76. As Patent Owner persuasively argued at the hearing, Doo’s curved plane is not “half of a cylinder. It’s just a wrapped piece of paper.” Tr. 33:14–15. Just as curving a piece of paper would not give the curved paper a half cylinder’s volume, neither does curving Doo’s flat 2D plane create a half cylinder with volume. Viewed another way, curving a 2D plane does not impart volume to the plane any more than curving a 1D line into a parabola would impart area to the 1D line.” slip op. at 12

“The U.S. Supreme Court has emphasized that “rejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” KSR, 550 U.S. at 418 (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Petitioner’s argument fails this standard. Petitioner asserts a generic rationale that one of ordinary skill in the art would have applied Amira to Doo “to take advantage of the visualization technology disclosed in Amira (or any similar visualization software).” Pet. 41. But Petitioner’s assertion contains no explanation why one of ordinary skill would have taken advantage of Amira’s technology in the context of Doo. Petitioner’s rationale is so vague and broad that it could be applied to combine any two references because it merely asserts that one reference would “take advantage of the . . . technology disclosed in” another. See, e.g., In re Van Os, 844 F.3d 1359, 1361 (Fed. Cir. 2017) (explaining that “a finding that a combination of prior art would have been . . . ‘intuitive’ is no different than merely stating the combination ‘would have been obvious’”). This approach wholly misses KSR’s “articulated reasoning” standard. See KSR, 550 U.S. at 418. The Reply’s assertion that reducing a surgeon’s cognitive load in Doo “suggests an improvement on conventional medical imaging displays, such as disclosed in Amira,” fares no better. Reply 20. This assertion again fails to explain why one of ordinary skill in the art would have combined Amira with Doo. For instance, Petitioner provides no explanation as to how Amira’s display would further reduce cognitive load. See Reply 19–20 (only vaguely referring to Amira’s “[t]racking capabilities [that] allow for . . . interaction with the visualization” (Ex. 1005, 14, 26)). Not only that, but Doo itself presents a solution for the cognitive load problem. See Ex. 1008 ¶ 14 (“The present invention is particularly adapted to manage the multitude of medical images needed to be viewed by a surgeon during an operation so that a surgeon is not required to look away from the patient, so that the surgeon does not have to sustain heavy cognitive loading.”). Petitioner does not persuasively explain why one of ordinary skill in the art would turn to yet another reference (like Amira) for an additional solution, or even what that solution would be.” slip op. at 23

“(2) Our analysis We agree with Patent Owner. Patent Owner’s plain reading of limitation 1(c) is correct, and under this reading, the combination of Shackle and Birrell fails to disclose or suggest limitation 1(c). Limitation 1(c) states in part: “at least one LED circuit having any number of LEDs . . . needed to approximately match the forward voltage drop of a first input voltage to the LED driver.” Ex. 1001, 27:22–25 (emphasis added). We have omitted the language “connected in series or series parallel” to highlight the grammatical relationship between the noun phrase “any number of LEDs” and the verb phrase “needed to approximately match.” The plain reading of this limitation is that the at least one LED circuit has any number of LEDs needed to approximately match the forward voltage drop of the LED driver input. Petitioner’s reading, that “the at least one LED circuit,” rather than “any number of LEDs,” must approximately match the forward voltage drop of the LED driver input, is strained and not grammatically plausible. See Reply 1–3. Petitioner does not assert there is an express disclaimer or disavowal in the specification that supports its position; Petitioner instead relies on examples disclosed in the specification to support its faulty interpretation of limitation 1(c). See Reply 2–3. These arguments are unpersuasive. It is axiomatic that we must not “limit[] the claimed invention to preferred embodiments or specific examples in the specification.” Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1346–47 (Fed. Cir. 2015). Not only that, but Petitioner’s citations to the specification better support Patent Owner’s position. In Petitioner’s view, the specification requires other non- LED components to be combined with one or more LEDs to “appropriately match the voltage.” Reply 2. The main example Petitioner relies on describes 38 LEDs having a total voltage drop of 114 V in a circuit with a bridge rectifier having a 6 V voltage drop. Id. at 2–3 (citing Ex. 1001, 16:64–17:7). Yet the 114 V voltage drop of the LEDs alone “approximately matches” the input voltage of 120 V, without the contribution of the bridge rectifier (6 V). Id. Indeed, 114 V out of 120 V is a 95% match. Thus, this example supports Patent Owner’s view that it is the voltage drop of the LEDs themselves, not the LED circuit as a whole, that must approximately match the LED driver input. See Sur-reply 6–7.” slip op. at 16

“combination. The first is that the proposed combination is not at all clear. Although Petitioner need not propose a bodily incorporation of different embodiments, Petitioner must provide a “reasoned analysis” explaining what the combination is. See DSS Tech. Mgmt., Inc. v. Apple Inc., 885 F.3d 1367, 1377 (Fed. Cir. 2018); In re Keller, 642 F.2d 413, 425 (CCPA 1981); see also Kinetic Concepts, Inc. v. Smith & Nephew, Inc., 688 F.3d 1342, 1368 (Fed. Cir. 2012) (“We must be careful not to allow hindsight reconstruction of references to reach the claimed invention without any explanation as to how or why the references would be combined to produce the claimed invention.”) (citation omitted). But the Petition never explains how or where Piepgras’s glass substrate would be combined with Piepgras’s alleged flexible substrate, the rope light of Figure 31. At most, Petitioner suggests incorporating the illumination device 500 of Figure 42 in the rope light of Figure 31. Pet. 48 (“Piepgras provides for configurations where a reflective platform (reflective substrate) mounts lighting system 500 in a manner applicable generally to the inventions of Piepgras . . ., and thus including the rope lighting application discussed above.”). As for the glass substrate, Petitioner merely states that “a POSITA would have found it predictable to configure the Shackle-Piepgras device to implement a flexible substrate mounted to the glass substrate, wherein at least one of the plurality of LED packages is mounted to the flexible substrate.” Id. (citing Ex. 1002 ¶ 150). This vague statement just parrots the claim language and does not explain anything about how the glass substrate would be included in the combination.” slip op. at 28

They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
