    “Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network. [0322] Having been routed over a communications network to the base unit 33, the incoming stream is read from the communications interface such as a WiFi access point 22, unpacked in an unpacker 25, decoded in a decoder 26 and then inserted into a suitable composition such as an OpenGL based composition in the compositor 29 for display on a central display device. Ex. 1005 ¶¶ 321–322 (emphasis added to portions quoted by Petitioner). Patent Owner notes that “[t]he Petition mistakenly cites to ¶ 322 of Beel but quotes ¶ 321.” PO Resp. 20 n.3. However, it appears that Petitioner has grafted together a portion of paragraph 321 that introduces peripheral device 32 with a portion of paragraph 322, which discusses features of base unit 33. However, this grafting has been done in such a way as to convey (incorrectly) that peripheral device 32, not base unit 33, includes unpacker 25, decoder 26, and compositor 29 that process the first processed video data received by the first peripheral device to generate second video data. Dr. Almeroth’s testimony, which copies Petitioner’s incorrectly altered quotation to paragraph 322 of Beel, is unreliable as to this claim limitation and is entitled to no weight.4 Thus, Petitioner has no expert testimony on which to rely for this claim limitation.” slip op. at 19

    “5 At the oral argument, when challenged on its reliance on paragraph 322, Petitioner argued that paragraph 321 of Beel teaches this limitation. Tr. 22:26–23:24. Petitioner did not make this argument in the Petition and, instead, raised it for the first time during oral argument; thus, it will not be considered. See Dell Inc. v. Acceleron, LLC, 884 F.3d 1364, 1369 (Fed.

Even if we were to consider this new argument, it would not be persuasive. As Patent Owner observes (PO Resp. 20), any processing performed by peripheral device 32 in paragraph 321 is on data received from the processing device and destined for the base station via the network, rather than data flowing in the direction of the first processed video data of claim 1.” slip op. at 22

Petitioner also argues that “[a]dditional experience could substitute for a formal degree or formal training (and vice versa).” Id. Patent Owner proposes a slightly different level of skill, arguing that a person of ordinary skill in the art “would have had a bachelor’s degree in Mechanical Engineering, Computer Engineering, Chemical Engineering, Materials Science, or a comparable field and at least two years of experience related to 3D printing, with additional experience potentially being a substitute for a formal degree or training (and vice versa).” Prelim.

    “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

Chang, however, does not mention, specifically, that Chang’s pump is a “diaphragm” pump. We note, however, that this claim clause does not state or require any specific type of pump. It merely requires a “pump.” Clause 1[e]/29[e], discussed below, however, does require a “diaphragm” pump. Petitioner here merely lays the foundation for this later clause by asserting that “Fang provides a straightforward suggestion of a diaphragm pump including a diaphragm housing component formed in a wall of the pump housing.” Id. at 18 (citing Ex. 1009 ¶¶ 24–25, Fig. 7; Ex. 1003 ¶ 97). Thus, Petitioner asserts, Fang teaches “an ‘air pump’ in pneumatic connection with the diaphragm that serves to generate negative air pressure,” and Chang teaches “the location of pump components (e.g., ‘motor’ [46]).” Pet. 33 (citing Ex. 1007 ¶¶ 72, 80, Fig, 6A; Ex. 1009 ¶¶ 19, 24).

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

    “(c) Petitioner Shows a Motivation to Combine Because Petitioner cites a portion of Denk that states, “for the same overall strength and rigidity, the weight may be reduced, or for the same weight, the strength and rigidity may be significantly increased in the load direction specified by the design,” we find that Denk provides a motivation to use its tubular component in the bicycle of Moechnig. Pet. 13–14; Ex. 1006, col. 2. We also credit Petitioner’s testimonial evidence regarding the motivation to combine because the record supports it. Ex. 1003 ¶ 57; Ex. 1006, cols. 1–2; Ex. 1007, 1:10–14; Ex. 1008 ¶¶ 1, 9, 49; Ex. 1010, 6:22–26. The record shows that lightweight components were desirable. See, e.g., Ex. 1006, col. 1; Ex. 1008 ¶ 1. We also agree with Petitioner that one of ordinary skill in the art would have reduced weight or improved strength relative to Moechnig, because Denk describes reducing weight or increasing strength as “specified by the design,” indicating that it is a matter of ordinary skill in the art to achieve less weight or more strength when applying Denk to Moechnig. Ex. 1006, col. 2. how Denk combined with Moechnig would have reduced weight or increased strength, because Denk itself indicates it would have done so. PO Resp. 24–25; Ex. 1006, col. 2 (“for the same overall strength and rigidity, the weight may be reduced”). We also do not agree with Patent Owner that “Denk provides no indication that it would be more lightweight than a standard steerer tube with equal wall thickness and circular profile,” because Denk provides an indication.

    “On this record, we are persuaded that Petitioner adequately establishes that Usui discloses all of the limitations of claim 1. Usui discloses that aluminum or aluminum alloy layer 15 is in electrical contact with titanium underlayer 13, and titanium nitride layer 14 is located “intermediate the [titanium underlayer] 13 and the aluminum or aluminum alloy layer 15” to prevent “reaction between the aluminum layer 15 and underlayer 13.” Ex. 1004, 3:27–29, 3:38–41, 3:58–63. Usui further discloses that “a capping layer is provided above layer 15,” and that “[p]referred capping layers are titanium nitride and combinations of as layer 18 of a group IVA metal, preferably titanium with a titanium nitride layer 19.” Id. at 3:67–4:6. Usui teaches that titanium nitride layer 19 is about 150 to 800 Å thick, and that the thickness of titanium underlayer 13 is between about 90 to 110 Å. Id. at 3:31–33, 4:6–8. Usui also teaches that the interconnect metallurgy structures described therein “exhibit[] enhanced electromigration characteristics” and “are especially useful for forming electrical connections or wiring such as between active and/or passive devices of an integrated circuit structure.” Id. at 1:8–14. Usui’s description of a plurality of metal layers (layers 13–18) and a capping layer formed over the plurality of metal layers (layer 19), along with its description of the structure’s usefulness for forming electrical connections in an integrated circuit structure, is sufficient, on this record, to establish that Usui discloses “an electrode stack including a plurality of metal layers and a capping layer formed over said plurality of metal layers” as recited in claim 1. Usui’s teaching that the capping layer is a refractory metal nitride (titanium nitride) that has a thickness (150–800 Å) greater than the bottommost layer of the plurality of metal layers (layer 13, 90–110 Å), sufficiently establishes, on this record, that Usui discloses the “said capping layer consisting only of a refractory metal nitride, said refractory metal nitride forming a top of said electrical contact and having a thickness greater than that of a bottommost layer of said plurality of metal layers” limitation of claim 1.” slip op. at 11

    “device.” This term appears twice in claim 11, once in the phrase “an orientation sensor to detect rotation of the mobile communication device,” and once in the phrase “rotation of the mobile communication device detected by the orientation sensor.” Ex. 1001, 39:13–14, 39:36–38. Patent Owner argues that we should construe this term as limited to “detecting the rotation of the mobile communication device as a whole, not the movement of individual components.” PO Resp. 15–18. Petitioner disputes this, arguing that “rotation of the mobile communication device” should be construed not only to cover rotation of the device as a whole but also should “encompass[] any rotation of the mobile communication device relative to any object, including itself,” which would extend to rotation of “any component of the device.” Reply 4–5. We need not resolve this dispute to determine the outcome of Petitioner’s asserted challenges to the ’246 patent. As discussed more fully below, under either party’s proposed construction of “rotation of the mobile communication device,” Petitioner has shown by a preponderance of the evidence that the challenged claims are unpatentable. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

    “On the record developed during trial, we are persuaded that Petitioner has shown by a preponderance of the evidence that Kalliola teaches “an orientation sensor to detect rotation of the mobile communication device,” where “rotation of the mobile communication device” includes rotation of the device as a whole, regardless of whether it also includes rotation of one portion of the device relative to another. Kalliola teaches “motion sensors integrated in WCD 100” that are “used to detect when WCD 100 is being moved,” as well as to detect “when user 110 moves WCD 100 too quickly for an accurate DoA estimation.” Ex. 1004 ¶¶ 84, 86. Although Patent Owner argues that Kalliola’s motion sensors do not detect rotation of the device, this is incorrect on the record as developed at trial. Kalliola teaches that the motion sensor may take “the form of a semiconductor gyroscope chip.” Id. ¶ 84. There is ample evidence that gyroscopes detect rotation. Ex. 1013, 38 (identifying as an “orientation sensor” a “[t]hree-axis gyro” and a “[d]ynamic [h]igh [r]ange [gyro]”); Ex. 1046, 49:18–20 (Dr. Feuerstein testifying that gyroscopes “can be used to detect angular velocity”); Ex. 1047 ¶ 47 (citing Ex. 1051, 170; Ex. 1053, 9) (Dr. Buehrer testifying that a person of ordinary skill in the art “would understand that gyroscopes are well-known inertial sensors that specifically detect rotational motion”).

    “whether Kalliola’s teaching of pausing and resuming its DoA estimation based on detected rotational motion, or Kalliola’s teaching of speeding up its DoA estimation based on detected rotational motion, amounts to determining direction based on rotation. Pet. 63–64; PO Resp. 25–27; Reply 24–27; Sur-Reply 11–14. On the record developed during trial, we are persuaded that the preponderance of the evidence supports a finding that Kalliola teaches determining direction based on rotation. First, Kalliola discloses “pausing a DoA estimation until the motion of the WCD is detected by the motion sensors,” then resuming “the updating of the DoA estimation” when motion is detected. Ex. 1004 ¶¶ 14, 84. Second, Kalliola discloses a “correction or compensation mode” that is “employed when user 110 moves WCD 100 too quickly for an accurate DoA estimation,” with this “increase[d] speed of the DoA estimation” being triggered by the “[i]ncreased activity detected by motion sensors in WCD 100.” Id. ¶ 86. As discussed above with respect to limitation 11(d), the detected motion that triggers either of these modes can be rotational motion of the WCD detected by a gyroscope.” slip op. at 22
