    “We agree with Patent Owner that Petitioner’s contentions in this ground do not cure the issues for limitations 1D and 1E. Petitioner’s contentions in this ground involve combining Khan and Ali’s teachings of identifying a horizon line and lane lines with Choe. For example, Petitioner argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have combined known elements according to known methods to yield predictable results” and that “[i]mplementing these known mathematical models in Choe’s calibration system, according to their known functions, would have yielded predictable results.” Pet. 39. Petitioner further argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have used a known technique (predictive models) to improve similar devices in the same way” and that “[u]sing predictive models for Choe’s lane and horizon prediction would have also applied a known technique (predictive models) to a known device (a manual annotator device) ready for improvement.” Pet. 40. Petitioner’s proposed combination, therefore, still relies on Choe’s teachings of transmitting an overlaid image to an annotator device. We note that Petitioner asserts that, “[o]nce Khan in view of Ali identifies the horizon and lane lines, it overlays the horizon line and/or lane lines on the video, as shown in the screenshots below.” Pet. 41–42. Although Petitioner mentions Khan and Ali’s teachings with respect to video here, Petitioner does not adequately explain how the teaching of an overlaid video would be combined with Choe’s single image annotator teachings. As discussed above, Choe discloses transmitting a single overlaid image to the annotator” slip op. at 23

    “Thus, Petitioner has not provided sufficient evidence and argument to explain how the additional teachings of Khan and Ali teach limitations 1D and 1E in combination with Choe. Petitioner, therefore, has not demonstrated unpatentability of claims 1–5 by a preponderance of the evidence. F. Obviousness over Choe and Workman (Claims 1–4) Petitioner asserts that claims 1–4 would have been obvious over the combined teachings of Choe and Workman. Pet. 47–52; Pet. Reply 26–30. Petitioner asserts that, “if [Patent Owner] alleges that Choe does not explicitly disclose which predictive models it uses or whether it uses predictive models to identify the horizon line, a [person of ordinary skill in the art] would have searched for references that use predictive models and how such models were used,” which “would have led to Workman, which discloses predictive models to identify the horizon line.” Pet. 47. According to Petitioner, “[u]sing Workman’s predictive model to identify the horizon line would also have merely been combining known elements ([convolutional neural networks (CNNs)] and annotation for camera calibration) according to known methods to yield predictable results and used known techniques (CNNs) to improve similar devices in the same way.” Pet. 48–49. Thus, Petitioner relies on Workman to teach a predictive model to identify a horizon line. See Pet. 47–49. Choe with respect to limitations 1D and 1E. Indeed, Workman involves horizon line estimation in single images. See Ex. 1011, 10 (§ 5) (“We introduced Horizon Lines in the Wild (HLW), a new dataset for single image horizon line estimation, to address the limitations of existing horizon line detection datasets.”).

    “According to the ’713 patent, “[p]urge tower 24 itself may be . . . recycled or otherwise discarded as desired.” Ex. 1001, 8:27–28. This description provides some support for Patent Owner’s view, because a purge tower too intimately integrated with the part would be difficult or impossible to recycle or discard. This is further supported by the ’713 patent’s statement that “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Id. at 8:30–34. It also is supported by Dr. Hickner’s testimony that the ’713 patent “clearly shows . . . the 24 purge tower separated from the part” and that “the purge tower is a separate physical object.” Ex. 2016, 28:8–10, 64:1–9. On the other hand, there is evidence supporting Petitioner’s view that, as long as the purge tower is generally separate from the part and the support structure, it may still make contact with those portions of the print. As noted above, “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Ex. 1001, 8:30–34. This language does not exclude locations adjacent to or in contact with the part or the support structure. Thus, determine that a “purge tower,” as that term is used in the context of the ’713 patent, may not be an integrated portion of a printed part or support structure but need not be free of all contact with the printed part or support structure.” slip op. at 9

  • BurdenNot shown unpatentable

    “There is evidence of record to support both Petitioner’s view and Patent Owner’s view. On the record developed at trial, however, we cannot say that the preponderance of the evidence favors Petitioner, who bears the burden of proof. See 35 U.S.C. § 316(e). Accordingly, Petitioner has not shown by a preponderance of the evidence that KISSlicer teaches printing a layer of a purge tower each time the printer switches one extruder to the operating mode. Because proving the obviousness of claims 1 and 16 requires such a showing, Petitioner has not shown by a preponderance of the evidence that claims 1 and 16 would have been obvious over the combination of Priedeman and KISSlicer. 5. Analysis of Remaining Claims Claims 2, 6, 7, 9, and 17 all depend, directly or indirectly, from claim 1 or claim 16. Accordingly, they all include the limitations of either claim 1 or claim 16. Because, as discussed above, Petitioner has not shown that the combination of Priedeman and KISSlicer teaches or suggests all the limitations of claims 1 and 16, Petitioner also has not proven by a preponderance of the evidence that claims 2, 6, 7, 9, and 17 would have been obvious over that combination of references.” slip op. at 21

    “We disagree with Patent Owner. First, Patent Owner’s reliance on Wonderland as announcing a rule having broad effect is misplaced. Patent Owner contends that the “Federal Circuit has confirmed that where the primary reference already includes the function of the secondary reference, an allegation to incorporate that function into the primary reference is improper hindsight and no motivation to combine exists.” Id. at 29 (citing Wonderland NurseryGoods Co. v. Thorley Indus., LLC, 988 F.Supp. 2d 479, 498–99 (W.D. Pa. 2013), aff'd, 644 F. App'x 1011 (Fed. Cir. 2016); citing Kinetic Concepts, Inc. v. Smith & Nephew, Inc., 688 F.3d 1342, 1368 (Fed.Cir.2012))). Patent Owner’s citation to Wonderland does not support the proposition for which it is cited, namely that the Federal Circuit has “confirmed” that incorporating a function from a secondary reference into a primary reference is “improper hindsight” that precludes a motivation to combine teachings from the primary and secondary references. In Wonderland, the district court denied an accused infringer’s motion for summary judgment of invalidity, in part, due to its finding that genuine issues of material fact existed for the issue of whether sufficient motivation to combine prior art existed. Wonderland, 988 F. Supp. 2d at 511. The Wonderland decision does not constitute a final ruling on that issue, and the Federal Circuit’s summary affirmance of the final ruling by the district court does not address the issue or reflect how the issue was resolved at trial. Wonderland NurseryGoods Co. v. Thorley Indus., LLC, 644 F. App’x 1011 (Fed. Cir. 2016). Second, Petitioner also correctly points out that although Ferro refers to wireless charging, it provides no implementation details. Ex. 1004 ¶ 36; Ex. 2003, 54:8–55:9. Ferro also describes manual options for initiating charging, Ex. 1003¶ 146 (citing Ex. 1004 ¶ 109), and that an ordinarily skilled artisan would have been motivated to apply Oyobe’s vehicle sensor to allow a user to initiate Ferro’s charging methods more easily without the user having to leave the vehicle, Ex. 1003 ¶¶ 151, 152.

Ex. 1110 ¶¶ 130–131. Specifically, paragraphs 130 and 131 describe that: the notification manager of the eventing and alerting subsystem 452 queries the configuration server 454 for the user's notification preferences and correlates these notification preferences with session manager 456 to determine the best notification method. That is, the notification manager queries the configuration server 454 and determines, for example, that the user has certain online notification preferences and certain offline notification preferences. If online, notify by, for example, the user's active session. If offline, notify by, for example, a txt message. . . .

Reply 4–5; see also id. at 3–6 (entire argument). A plain reading of a “model associated with a base station” would encompass a model that operates in a base station. We do not see anything in the ’704 specification that would indicate “associated with” has any special meaning, or has a meaning contrary to our understanding of the plain meaning. We do not see the word “associated” outside the claims, whereas we see the word “implement” throughout the specification, generally in reference to an actual use of a model (consistent with our plain reading). See, e.g., Ex. 1001, 5:35–39, 6:3–17, 10:55–11:3 (discussing “implementations” where the model or some other feature of the system is used in a particular way).

    “scenarios” (see PO Resp. 16–21), Patent Owner argues that “Jüschke does not disclose any association of the weight or bias parameters, . . . to any deployment scenario, and . . . base station” (id. at 19). For the reasons explained in our claim construction section above, we construe “deployment scenarios” to include “inline mode” models located within a base station, according to the list of deployment scenarios set out in the ’704 patent. See Ex. 1001, 2:38–65. The in-line deployment scenario depicted in Figure 6A of the ’704 patent bears a striking resemblance to the arrangement depicted in Figure 1 of Jüschke. In both figures, the analog radio signal is fed directly into the model and then the model directly outputs the signal to the amplifier. Compare Ex. 1001, Fig. 6A, with Ex. 1005, Fig. 1. As construed, the “deployment scenarios” represent the physical configurations of the device in which the model is found, such as “in-line.” Petitioner shows by a preponderance of the evidence that Jüschke’s similar in-line configuration is a “deployment scenario” as claimed because it teaches an inline model for a cellular system transmitter (i.e., base station).

    “Based on our claim construction analysis of claim 4, above, we agree with Patent Owner that claim 4 requires an actually transmitted signal and an update of the transmitter’s model. This claim construction eliminates Petitioner’s position regarding Holt teaching a modeled signal. See, e.g., Pet. Reply 17–23. We then turn to Petitioner’s argument that Holt teaches updating a model using an actually transmitted signal. See Pet. 59–60. There, Petitioner relies on a disclosure in Holt of an “actual communication channel 302 used to train the channel model 208.” Ex. 1006, 18:1–2. This is depicted in Figure 6 of Holt, in connection with a “fourth loss function” which is used to “train the decoder model.” Id. at 18:42–48; see generally id. at 17:58–18:51 (describing Figure 6). Whether training the channel model or the decoder model, Holt here does not disclose using the actual communication channel to train the encoder, i.e., transmitter. In sum, we find that Petitioner has not shown by a preponderance of the evidence that the prior art describes the claimed step of “obtaining a received radio signal,” and even if it did, Petitioner has not shown by a preponderance of the evidence that the prior art describes the claimed step of “updating the value of the model parameters” in the manner required by claim 4. Claims 12 and 20 are nearly identical to claim 4, and Petitioner’s ground fails for similar reasons. See Pet. 76.

    “said integrity is compromised, then also providing an indication of said compromised integrity.” Ex. 1001, 20:65–21:2. Although Petitioner points out that the limitation does not expressly recite “‘specifically’ monitoring the tight coupling” (Pet. Reply 8), the structure of the clause suggests that the tight coupling is specifically monitored. At a high level, the limitation is straightforward in its recitation that the integrity being monitored is “of the tight coupling” (Ex. 1001, 20:65–66 (emphasis added)), plainly suggesting that the tight coupling is specifically monitored. More granularly, breaking the relevant clause down to its grammatical parts, the clause recites a gerund (“monitoring”) acting on a direct object (“the integrity”) which is modified by a prepositional phrase (“of the tight coupling”). Notably, the object of the preposition (“of”) is “the tight coupling.” Altogether, this reads that the integrity being monitored is specifically of the tight coupling. Also, the claim recites that “if said integrity is compromised, then also providing an indication of said compromised integrity.” Therefore, from the claim language we know that the “integrity” of the tight coupling is something that may be “compromised,” which is consistent with Patent Owner’s proposed construction of determining whether the physical coupling has been “accessed or disturbed.” Petitioner’s interpretation effectively inserts additional language into the limitation such that the limitation includes monitoring the integrity of a device containing or surrounding the tight coupling, such as a camera (or camera housing), e.g., “monitoring the integrity of a camera that includes the tight coupling.” But, because the plain reading and the structure of the limitation reads that it is specifically the tight coupling’s integrity—not another physical structure, like a camera—which is being monitored, a monitored is not consistent with the language of the claim. See PO Resp. 9 (arguing that “Petitioner’s construction is improper because the claim language explicitly requires monitoring the physical coupling between the memory and the sensor as opposed to some third structure” (emphasis omitted)).” slip op. at 17

Petitioner’s proposed modification of Lundahl also involves using LEDs as a light source instead of Lundahl’s fluorescent tubes. Id. According to Petitioner, a POSITA would have been motivated to make this change because: (1) LEDs had a lower cost and a longer lifetime than fluorescent tubes; (2) fluorescent tubes were known to have inconsistent light output within the tube itself; and (3) “the use of LEDs would be more practical to reduce spacing between light sources and the edges of the panels, as opposed to the bulky metal couplings at the end of fluorescent tubes, to reduce optical dead space across the light surface.” Id.

This argument ignores that Larsen expressly identifies hinges on at least bottom side surfaces, and Petitioner merely proposes modifying their location from the bottom sides to inner sides. We find credible Dr. Grove’s testimony that relocating hinges would have been within the level of ordinary skill in the art. Ex. 1015 ¶ 155.

Petitioner’s argument that having “rental microbusiness” implemented as a “smart phone application” that enables sharing virtual keys is insufficient to show obviousness, because, as noted by Patent Owner, certain embodiments in Kleve appear to discourage or even hinder the sharing of virtual keys. These embodiments require the use of credentials associated with the virtual key, where the credentials can be “facial recognition, voice print recognition, matrix barcode (ex. two-dimensional code), code word or phrase for speech recognition, temporary mobile web login IDs and password, or other types service.” See Ex. 1005 ¶ 37. Dr. Almeroth testifies that multiple people could be authorized on the same vehicle if they collectively rent a vehicle and that a person of ordinary skill in the art would “have been motivated to enable each user to share the virtual key with other authorized users associated with the same rental request.” Ex. 1004 ¶ 55. But given Kleve’s disclosure that the system handles key generation and distribution (Ex. 1005 ¶ 39), the evidence does not show that a person of ordinary skill in the art would have wanted to give this control to each authorized user who has received an e-key. “It is impermissible to use the claimed invention as an instruction manual or ‘template’ to piece together the teachings of the prior art so that the claimed invention is rendered obvious.” Fritch, 972 F.2d 1260, 1266 (Fed.
